1. UBC SAFETY ORGANIZATION STRUCTURE

The role and responsibility of the UBC-RMS is to provide programs, services, assistance and

guidance to the university community on all aspects of health, safety and environmental

matters. The department also works with standing University committees which make

recommendations on health and safety issues. UBC-RMS promotes the participation of all

faculty, staff and students in safety committees and in addressing health and safety issues

of concern. Several training course are held throughout the year to assist employees in

developing departmental programs. For information on courses refer to:

www.riskmanagement.ubc.ca/courses. For UBC-RMS organizational chart refer to:

http://www.hse.ubc.ca/about-hse/organizational-chart.

The completion of the UBC-RMS Laboratory Chemical Safety Course and Fire Extinguisher

Training are mandatory for all faculty, staff and graduate students who handle hazardous

materials. This requirement must be completed before commencing any work in the

Chemistry Department research and/or instructional laboratory areas. For more

information contact: [email protected]

UBC safety committees fall into one of the three general categories:

• The University Health and Safety Committee, which has representatives from all areas

of the University.

• Faculty Advisory Committees dealing with special health and safety and environmental

problems.

• The Local Safety Committees (LSC) which form the backbone of the health, safety and

environmental programs at the university.

1.1 UBC RISK MANAGEMENT SERVICES

1.2 UNIVERSITY SAFETY COMMITTEES


1.2.1 The University Health and Safety Committee

This committee consists of 19 members representing various aspects of the University

community and is structured to comply with the Industrial Health and Safety Regulations. The

primary goal of this committee is to provide recommendations which assist the University by in

carrying out its safety policy. The Director of Health, Safety and Environment is not a member

of this committee. The Director is, however, a resource person to the Committee and the office

of Health, Safety and Environment, and can provide secretarial and technical assistance where

required.

1.2.2 Advisory Committee

The Advisory Committee consist of the University Committee on Radioisotopes and Radiation

Hazards, the University Biosafety Committee, the University Chemical Safety Committee, the

University Underwater Diving Committee, the Environmental Programs Committee, the

Asbestos Control and Training Steering Committee, and the Personal Security Committee. The

first six Advisory Committees report through the vice-president of Research while the latter

reports through the vice-president of Administration and Finance.

1.2.3 The Local Safety Committee (LSC)

The LSC represents a smaller component of the University safety network. There are over 80 of

these committees. The nature of these committees varies from area to area, as does the

frequency of these meetings. Copies of the minutes of these committees are reviewed by RMS

and by the University Health and Safety Committee. Appropriate actions are taken as

necessary.

UBC and the Department of Chemistry are committed to providing a healthy, safe and secure

workplace for all workers. As a part of this commitment the Chemistry Department has

developed a comprehensive Safety Program. This program is based on, and requires

2. BASIC SAFETY INFORMATION

Before Students/staff commence working in any ChemDept research or instructional labs

they are required to have completed the UBC Risk Management Chemical Safety Training

(RMS150 & 151) and attended for Fire Extinguisher Training. Your supervising Faculty

may require additional UBC Risk Management training courses and lab specific training;

discuss this with your supervising Faculty Member.

YOU are required to maintain a personal record of your UBC Safety Training and provide a

copy of your records/documents/Certificates to your supervising Faculty to document

completion of all UBC Safety Training requirements.

You must wear a lab coat and safety glasses at all times when working in laboratories at

UBC. Only 100% cotton lab coats are acceptable for use in any of the ChemDept research or

instructional labs.

Absolutely no food or beverages are to be consumed or stored in areas designated as lab space.

Garbage/waste containers in lab space cannot be used for food/beverage waste materials.

If you find any spills that need to be cleaned up, notify the ChemDept Safety Office. Spills that are

not cleaned up promptly can result in serious slip-and-fall injuries.

If you use any supplies from ChemDept Spill Karts in the process of cleaning up spills, complete a

Spill Report Form or e-mail so that the Spill Kart can be reviewed and re-stocked.

2.1 MINIMUM SAFETY TRAINING

2.2 LAB COATS AND SAFETY GLASSES

2.3 FOOD AND BEVERAGE IN LAB AREAS

2.4 SPILLS


Review the Emergency Procedures Posters so you know how to get assistance in the event of

physical injuries. Accident/Incident Reports are required to be submitted to the ChemDept Safety

Office within 24-48 hours of the event.

No one is permitted to utilize an elevator while it is transporting a full liquid nitrogen cylinder. If

you need to transport a liquid nitrogen cylinder in a departmental elevator, make sure the proper

caution strap is attached across the entry of the elevator.

It is recommended that you avoid working alone in the laboratory. If you need to be in the

laboratory after hours, keep friends and family informed of your schedule to avoid worries. Let

someone (your supervisor or someone from the next door lab) know that you are planning to be in

the laboratory alone, so they can come and check up on you. Keep a record of hourly contact with

someone.

If you are walking alone to your car or home at night, you have several campus resources that you

can utilize, such as:

The AMS Safe Walk program, call (604) 822-5355 or visit the website at:

3. ACCIDENT INVESTIGATION & REPORT

The purpose of the accident reporting and investigations is to prevent a recurrence of the

hazardous condition causing the event. The goal of the accident investigation is to find solutions

and not to place blame. The success of the accident investigation depends on:

accidents being reported by workers

investigations being conducted with established procedures

corrective action taken to prevent recurrence

The WCB must be informed immediately if any accident occurs that:

results in death or critical condition with a serious risk of death

involves a major structural failure or collapse of a building

involves a major release of a toxic or hazardous substance

was an accident required by regulation to be reported

The Department is also required to report to the UBC-WCB Claims Assistant, Dolly Hsiao, phone

(604) 822-8759 or e-mail [email protected] for every:

work-related injury (the report must be made within 24 hours of the occurrence).

disabling occupational disease or allegations of an occupational disease (the report must be

made within 24 hours of receiving the worker’s report of the disease).

work-related death (the report must be made immediately).

4. PERSONAL CLOTHING/ACCESSORIES & PERSONAL PROTECTIVE

EQUIPMENT (PPE)

4.1.1 Supervisor’s Responsibilities

The supervisor must ensure that appropriate personal protective equipment is: available to workers properly worn when required properly cleaned, inspected, maintained and stored.

4.1.2 Worker’s Responsibilities

A worker who is required to use personal protective equipment must: use the equipment in accordance with training and instruction inspect the equipment before use refrain from wearing protective equipment outside of the work area where it is required if to do

so would constitute a hazard report any equipment malfunction to the supervisor or employer. a worker who is assigned responsibility for cleaning, maintaining or storing personal protective

equipment must do so in accordance with training and instruction provided

Personal clothing of a worker must be of a type and in a condition which will not expose the worker to any unnecessary or avoidable hazards. (See WCB OHS Reg 8.10) Shorts, skirts (including for women pantyhose/tights/leotards) and sandals are not appropriate in lab areas and may pose significant safety risks. In clothing fires, burns are often deeper and cover more skin surface. Many synthetic fabrics cause severe burns because they melt and form a hot, tacky residue which sticks to the skin. These kinds of burns are more likely to cause hospitalization and death. Many times hospital treatment from clothing burns is longer and more extensive.

4.1 RESPONSIBILITIES

4.2 PERSONAL CLOTHING AND ACCESSORIES


Consider wearing light weight, loose fitting clothing made of 100% cotton with a smooth, tightly woven finish or wool fabrics. Avoid clothing made of synthetic fabrics such as nylon, polyester, acetate and acrylic, and especially avoid laminated fabric containing polyurethane sponge, as this ignites and burns quickly. Dangling necklaces, bracelets or similar jewelry should be removed when working in lab areas. Medical alert bracelets can be worn with transparent bands that hold the bracelets snugly to the skin. Long hair should be restrained, away from the face area.

Use of PPE should only be considered after material substitution, administrative controls and engineering controls are evaluated. When there is a risk of employee exposure the employer must provide personal protective equipment. Employee should be trained in the proper use and storage of PPE PPE requirements need to be evaluated at least annually and based on the hazard exposure.

Typical PPE will include: eye and head protection, body protection (gloves, aprons), and respiratory protection, if Threshold Limit Value (TLV) is to be exceeded. Refer to PPE Selection Table below for more information.

Basic PPE For basic laboratory work always wear lab coat, safety glasses, appropriate gloves, long pants and closed-top shoes. Dangling necklaces, bracelets or similar jewelry should be removed when working in lab areas. Medical alert bracelets can be worn with transparent bands that hold the bracelets snugly to the skin. Long hair should be restrained, away from the face area. See also: Personal clothing and accessories (above VIDEO: PPE BASIC

4.3 PERSONAL PROTECTIVE EQUIPMENT (PPE)

http://www.chem.ubc.ca/safety/safety_manual/whmis_how_to.shtml#pelhttp://www.chem.ubc.ca/safety/safety_manual/protective_equip.shtml#selection#selectionhttp://www.chem.ubc.ca/safety/safety_manual/cd1-intro1.html


Should be used when there is hazard from: flying particles liquid chemicals acids and caustic liquids gases and vapors injurious light chipping, grinding, welding

Face shield Use Face Shield when working with a high volume of chemicals. Note the Safety Glasses under the Face Shield.

Eye protection

Use special Safety Glasses or Goggles to protect against injurious light, such as these glasses that protect eyes against laser radiation

Use Chemical Goggles when there's a risk of exposure to toxic or irritant fumes.

4.4 EYE AND FACE PROTECTION


4.4.1 Eye Protection when Working with Chemicals

Adequate eye protection is required for all individuals in the laboratory. Do not remove your eye protection until you have physically left the lab room. The following types of eye protection are acceptable:

Protective glasses should meet the requirements of ANSI Standard Z87.1-1989, Practice for Occupational and Educational Eye and Face Protection.

For labs (particularly organic) where exposure to toxic or irritating fumes could be a problem, the best form of eye protection is safety goggles that will form a tight seal to your face.

A full-face shield is highly recommended when there is a risk of explosion or splashing, or with combustion and high temperature reactions.

If there is a risk of face injury, suitable face protection must be worn. Face protectors and non-prescription safety eyewear must meet the requirements of: CSA Standard CAN/CSA-Z94.3-92, Industrial Eye and Face Protectors, or ANSI Standard Z87.1-1989, Practice for Occupational and Educational Eye and Face

Protection.

4.4.2 Normal prescription eyeglasses

Normal prescription eyeglasses or safety glasses, either with or without safety side-shields are

acceptable, as long as the lenses are shatterproof and cover a large enough area surrounding your

eye (this usually means that the frames must be a minimum of 4 cm from top to bottom as well as

from side to side). NOTE: check size restrictions with the instructor or PI

Protective glasses/goggles and face shields that cover prescription eyeglasses are available commercially and/or from Chemistry Stores.

Bifocal and trifocal eyeglasses must not be used if there is danger of impact unless they are worn behind impact-rated goggles or other eye protection.

4.4.3 Contact Lenses

The wearing of contact lenses in the chemical laboratory has historically been perceived as a safety hazard. Some concerns are:

chemicals splashed into the eyes can become trapped under or absorbed by the lenses; some chemicals cause coagulation of the protein in the eye within seconds; chemical vapors trapped under or dissolve into soft lenses; the difficulty to remove lenses if something has been splashed into your eyes.

More recently, both the American Chemical Society and the (American) Occupational Health and Safety Administration have issued statements indicating their studies suggest the wearing of contact lenses does not pose any additional hazard and can be treated as safe if, and only if, safety glasses or goggles are also worn.


If you choose to wear contact lenses in the laboratories you are required to inform and discuss this with your supervisor (Faculty member, lab director and/or TA's) before commencing any work with chemicals. It is important that we know this fact in the event of an injury to your eyes.

It is recommended that you not wear contact lenses when working with: acrylonitrile, methylene chloride, 1,2 dibromo-3-chloropropane, ethylene oxide, and methylene dianiline.

Use appropriate skin, hand, foot or body protection if a worker is exposed to a substance or condition which is likely to puncture, abrade or otherwise adversely affect the skin, or be absorbed through it. If there is a danger of injury, contamination or infection to a worker's hands, arms, legs, or torso, the worker must wear properly fitting protective equipment appropriate to the work being done and the hazards involved.

4.5.1 Gloves

Use when there is a risk of: cutting materials, working with extreme temperature chemical burns hazardous material skin absorption Depending on the procedure to be carried out, different types of gloves must be available in the laboratory. The gloves should “fit” the chemical. Check for appropriate: glove material, permeation rating, and breakthrough time. Asbestos gloves should not be used. If any are found, they should be replaced. Gloves are made from a variety of materials which vary in their permeability and wear-

resistance. Disposable gloves are made of PVC, latex, nitrile, and combinations of the aforementioned.

These gloves are for general use and have low abrasion resistance. More resistant, impermeable, reusable gloves are made from butyl rubber, nitrile, or neoprene. For more information on gloves resistance see the glove chart.

4.5 BODY PROTECTION

http://www.chem.ubc.ca/safety/safety_manual/protec_equip_body.shtml#permeation#permeationhttp://www.ansellpro.com/download/Ansell_7thEditionChemicalResistanceGuide.pdf


Nitrile gloves are highly resistant, give maximum protection from liquid chemicals. Thin Nitrile Gloves (purple) are good for general use; Heavy-duty Nitrile Gloves (green) are for a heavy volume of chemicals; also for spill clean-up

Rubber: good chemical resistance, low abrasion resistance

Neoprene: almost impermeable to regular solvents, fairly abrasion resistant


Kevlar Gloves: cut resistant for handling glassware

Use Heat-Resistant Multi-Composite Gloves to protect high or low temperatures or special procedures.

4.5.2 Lab aprons or lab coats

The strength and permeability of aprons depends on the materials used.

Aprons should be fire-resistant, chemical-resistant, and easily washed. Flammable fabrics should be avoided. Lab coats should be made of strong fabric and must be able to be removed quickly in

case of accident. They must be long enough to protect the legs. Lab coats exposed to harmful chemicals should not be worn in public areas.

4.5.3 Footwear

Worker’s footwear must be of a design, construction, and material appropriate to the protection required. To determine appropriate protection the following factors must be considered: slipping, uneven terrain, abrasion, ankle protection and foot support, crushing potential, temperature extremes, corrosive substances, puncture hazards, electrical shock and any other recognizable hazard.


If a determination has been made that safety protective footwear is required to have toe protection, metatarsal protection, puncture resistant soles, dielectric protection or any combination of these, the footwear must meet standards requirements (refer to Occupational Health and Safety regulations for details) Footwear for chemistry laboratory work:

Substantial shoes must be worn and should cover the entire foot. Open-toed shoes and sandals must not be worn in the laboratory. Safety shoes or foot guards may be required under certain circumstances (e.g., when

moving compressed gas cylinders – foot guards are available in cylinder storage area).

When cleaning up floor spills wear plastic foot covers available on all spill carts.

Respiratory protection is required when toxic chemicals are used outside the hood and there is a potential to exceed allowable exposure limits.

Use of respirators should be considered to control exposure only after engineering and administrative controls have been considered. These types of controls include ventilation (e.g. fume hoods), enclosing the process, substitution with less hazardous products, rescheduling of work procedures, etc. Users are responsible for:

Obtaining proper certification for respirator use from the Department Safety Program Administrator

Using the respirator in accordance with training instructions Being properly fit-tested for a respirator Cleaning, disinfecting, and storing the respirator Reporting any respirator malfunction to their supervisor

4.6 RESPIRATORY PROTECTION

http://regulation.healthandsafetycentre.org/s/Part8.asp#SectionNumber:8.22


5. CHEMICAL FUME HOOD

1. Conduct all operations which may generate air-born contaminants inside a hood; 2. Always wear appropriate eye protection, gloves, and a 100% cotton lab coat when

working around a fume hood; 3. Do not raise the sash higher than the labeled height. This will reduce hood

efficiency; 4. Keep apparatus at least 15 cm from the front edge of the hood; 5. If the hood is used for semi-permanent experiments, post the name of the person in

charge, experiment title, and possible hazards; 6. Do not store chemicals inside the hood. Hazardous chemicals should be stored in an

appropriate safety cabinet; 7. Keep your face outside the plane of the hood opening; 8. Avoid cross drafts at the face of the hood. Minimize foot traffic past the hood and

position windows and supply air diffusers to direct air flow away from the hood; 9. Do not place electrical receptacles or other ignition sources inside the hood when

flammable liquids or gases are present; No permanent electrical receptacles are permitted in the hood;

10. Avoid blocking the rear ventilation slot. Material stored at the back of the hood should be stored on an elevated shelf so that the slot air flow is not impeded;

11. Leave the sash lowered when the hood is unattended; 12. Keep the bypass grill clean.

Good experimental design requires that hood users develop a plan of action to follow if the fume hood fails. This planned procedure should include the following steps: 1. If serious hazard of fire, explosion, or toxic gas release is created in the laboratory, call the Fire

Department (911). 2. Shut down any experiments and make the hood as safe as possible (See UBC Plant Operations

Shut Down Procedures). 3. Report "Trouble Calls" to Main Office (Lani Collins 2-2189) or direct to Plant Operations (2-

2173). 4. Prepare the hood for maintenance and tag the hood sash as "Out of Service - Do Not Use". (Use

suitable paper and affix to the lower edge of the sash.) 5. Advise Chemistry Administrator 2-2752 and Safety Program Administrator 7-5216.

5.1 SAFE WORK PRACTICES

5.2 LABORATORY PROCEDURE


Hood users should incorporate the following elements into their emergency planning in order to facilitate the emergency shut down of experiments being conducted in fume hoods:

An understanding of the hazards associated with the materials being used. Keep the amount of toxic material in use to a minimum.

The provision for personal protective equipment such as chemical cartridge respirators which will provide protection from chemicals in use.

A planned experimental shut down procedure, so that the experiment may be shut down safely. (Some experiments may be safely interrupted, but it may be safer for others to be driven to completion). Shut down includes: closing chemical containers, closing off heat, relieving all pressures, removing hazardous substances and monitoring for radioisotopes.

Determining if evacuation of the lab would be required and if the Fire Department should be called.

All extremely hazardous chemicals, compressed gas and/or lecture bottles must be REMOVED from fume hood The following items may remain in the Fume Hood:

PROPERLY IN A SHARPS CONTAINER.

All disposable syringes must be disposed of special waste. Biohazardous syringes and biohazardous "Sharps" containers must be autoclaved or

chemically decontaminated prior to disposal and require a Biological Waste Disposal Tag (Red) with generator barcode attached.

Low Volume Syringes can be disposed of completely with needle, plastic syringe barrel and plunger in a “SHARPS" container, dispose of using Biological Waste Disposal Tag (Red) with generator barcode attached.

High Volume Syringes. Remove the needle from the syringe barrel and collect the needle in a “SHARPS” container, dispose of using Biological Waste Disposal Tag (Red) with generator barcode attached.

Collect the syringe barrels without needle in plastic bags biohazardous syringe barrels must be autoclaved or chemically decontaminated

prior to disposal and require a Biological Waste Disposal Tag (Red) with generator barcode attached.


non-biohazardous syringe barrels can be disposed of using a Non-Regulated Contaminated Solid Waste Tag (Yellow) with generator barcode attached; complete "Other" as “PLASTIC WASTE FOR INCINERATION".

Take to the designated waste disposal site. Note that all waste, emissions, and hazardous materials procedures must comply

with UBC Policy # 6 (Environmental Protection Compliance) which can be viewed at http://www.policy.ubc.ca

6.4.4 Disposal of Sharps and Needles

This procedure applies to the disposal of ALL sharps and needles that may be contaminated or uncontaminated by biohazardous agents. Sharps and needle disposal may include the following components:

Sharp metal cutting blades (e.g. scalpels); Disposable plastic low volume syringes; and, Needles

Figure 1 - A sharps container with

disposal tag.

Sharps and needles must be collected in red or yellow sharps containers made of a hard impervious plastic that is both autoclavable and acceptable for incineration. They must be labeled with a Biological Waste Disposal Tag (Red) on the outside. These containers are available in Chem Stores. Only APPROVED sharps containers may be used for these wastes. These containers must not be used for any other purpose.

Collect all sharps and needles in approved plastic "sharps containers".

Do not fill the container past the indicated “Full” line. Chemically decontaminate all infectious items prior to disposal

into the container or, autoclave the entire container once it is full.

Securely close and snap the lid in place. Take to the designated waste disposal site. Do NOT put sharps into plastic bags. Containers must be tagged with the Biological Waste Disposal

Tag (Red) with generator barcode attached. Identify waste content by checking the appropriate box on the tag and fill out the requested information.

Note: sharps containers MUST NOT be placed into the "Glass Waste Only" cans

http://www.policy.ubc.ca/


6.5.1 Pathological Waste

Pathological waste includes: Animal Carcasses, Pathological Material, Biological Material, Infectious Material, Expired Drugs, Sharps and Needles

Package sharps and needles into heavy plastic sharps containers. Package other material in heavy black or orange hospital plastic bags. Weight of bag

must not exceed 15 kilograms (30 pounds). Double bag if material is wet and messy, to prevent leakage. Tie securely and attach Biological Waste Disposal Tag (Red) and generator barcode

to each bag. Complete the tag as required to indicate type of material

Figure 2 – A properly bagged and labelled biological waste disposal bag

6.5.2 Non-Indigenous Species Waste

Non-indigenous species are defined as species that are not native (indigenous) to an area and have been introduced through human activities either on purpose or by accident. Materials that may contain non-indigenous species include:

Algae and plants; Animal bedding materials; Cloned and genetically altered organisms – all types. Cultured organisms, microorganisms, plants and animals; and,

6.5 PATHOLOGICAL AND NON-INDIGENOUS WASTE


Single pass and re-circulating fresh and saltwater cooling or aquarium systems; Soils – all types; Terrestrials and aquatic plants and animals including those on baits, nets and

sampling equipment; Disposal of non-indigenous species will be considered as Risk Group II with moderate individual and limited community risk. All Risk Group II waste MUST be contained in ORANGE autoclave bags (bags may be purchased from any laboratory supplies vendor). The bags MUST then be autoclaved sufficiently to render the organism in question harmless. Autoclaved bags must be leak proof. To prevent leaks and breakage during storage or transportation, double bagging with a clear plastic bag is required. Environmental Services Facility (ESF) must be able to package the bag into a box (length – 22”, height – 22”, width – 22”) from our disposal supplier. Therefore, the maximum size of the bags must be less than the aforementioned box dimensions.

Each bag must not weigh more than 10 kg. Do not put glass or sharps in with Risk Group 2 waste. After autoclaving, bags must be tagged with the UBC Environmental Services

Biological Waste Disposal tag (Red), Affix your waste generator number sticker where indicated. On the tag, check off the box marked “Autoclaved Risk Group II” and place it in the building's designated area for pick-up by ESF.

Hazardous waste produced as a result of chemicals being left over from, or the products of, an experiment. A concerted attempt should be made to minimize hazardous waste generation using the “3 R’s”: reduce, reuse, and recycle. Examples of minimization methods include: using diluted rather than concentrated solutions; using micro or semi-micro techniques; considering the substitution or elimination of extremely hazardous materials through the use of less hazardous materials; using films, videotapes or demonstrations in teaching situations rather than individual experiments.

6.6 CHEMICAL WASTE DISPOSAL


6.6.1 General Waste Chemicals

Figure 3 – A properly packaged and labeled box of chemicals

for disposal

Go to RMS’s Chemical Waste Inventory System, complete and submit your chemical waste inventory on-line.

Once approved forms are returned, the chemicals should be packed into a sturdy cardboard box with vermiculite, according to the class or code noted. The approved waste disposal form should be placed in an envelope and taped onto the top of the box.

On the top of the box, write the correct chemical classification code in 3 inch sized letters. Also, write on top of each box the generator’s name, department number, and telephone number.

Take boxes to the designated waste disposal site.

6.6.2 In-Lab Chemical Waste Treatment

The small-scale treatment and deactivation of products and by-products as part of the experiment plan is one approach that can be used by researchers to address this problem at the laboratory level. Below are some treatment suggestions for use in the laboratory. This information was extracted from: Prudent Practices in the Laboratory (1995), National Research Council. (Online version http://www.nap.edu/catalog/4911.html). Use only the procedures specific to the waste you intend to neutralize. With the exception of neutralization, these processes are intended for treatment of small quantities, not more than a few hundred grams. Larger quantities should be treated only in small batches. The generator must ensure that the procedure eliminates the regulated hazard before the products are disposed of as non-hazardous waste. In addition, if the procedure suggests disposal of the product into the sanitary sewer, it must comply with the Vancouver Sewerage and Drainage District, Sanitary Sewage Waste Discharge prohibitions and restrictions www.metrovancouver.org/boards/bylaws/Bylaws/GVSDD_Bylaw_299.pdf

6.6.3 Disposal of Waste Oil

IMPORTANT NOTE: Waste oils must not be contaminated with PCBs (Polychlorinated Biphenyl) or solvents.

http://www.hse.ubc.ca/cwif/http://www.hse.ubc.ca/cwif/http://www2.chem.ubc.ca/safety/safety_manual/waste_designated_location.shtmlhttp://www2.chem.ubc.ca/safety/safety_manual/waste_designated_location.shtmlhttp://www.nap.edu/catalog/4911.htmlhttp://www.metrovancouver.org/boards/bylaws/Bylaws/GVSDD_Bylaw_299.pdf


The oil can be collected in three ways:

Supplier’s original disposable plastic container if it is in good condition (i.e. not leaking);

Labeled 4L plastic bottles; or,

205 litre metal drums.

Do not use red solvent cans for disposal of waste oil. If you require empty oil containers, please contact the ESF Technician at (604) 822-6306 or (604) 822-1285.

Use Flammable Liquid Disposal Tag (Blue) and affix the generator barcode sticker. Write the type of oil in the container (on the line of the tag entitled “Other”):

i.e. Types of waste oil include the following:

Automotive lubricating oil;

Cutting oil;

Fuel oil;

Gear oil;

Hydraulic oil;

Refined petroleum based oil;

Synthetic oil;

Emulsion;

Crude oil; and,

Vacuum-pump oil.

.

Make sure that all waste oil containers are properly tagged and identified, with lids

tightly closed.

Place the containers on the carts in Cage #2 for pickup by ESF.

Do not mix waste oil with other solvents.

Do not overfill containers.

6.6.4 Acids and Bases

In most laboratories, both waste acids and waste bases are generated. Collect them separately and neutralize one with the other. If additional acid or base is required, sulfuric or hydrochloric acid and sodium or magnesium hydroxide, respectively, can be used. If the acid or base is highly concentrated, first dilute it to a concentration below 10%. Non-toxic neutralization products may be disposed of through the sanitary sewer. Toxic products such as ones containing heavy metals and toxic ions such as cyanide and sulphide should be disposed of according to approved protocols.


6.6.5 Thiols and Sulfides

Small quantities of thiols (mercaptans) and sulfides can be destroyed by oxidation to a sulfonic acid with sodium hypochlorite.

6.6.6 Acyl Halides and Anhydrides

Acyl halides, sulfonyl halides, and anhydrides react readily with water, alcohols, and amines. They should never be allowed to come into contact with waste that contains such substances. Most compounds in this class can be hydrolyzed to water-soluble products of low toxicity.

6.6.7 Aldehydes

Many aldehydes are respiratory irritants, and some (formaldehyde, acrolein), are quite toxic. They can be oxidized to the corresponding carboxylic acids, which are usually less toxic and less volatile.

6.6.8 Amines

Acidified potassium permanganate efficiently degrades aromatic amines. The mixture is then flushed down the drain.

6.6.9 Organic Peroxides and Hydroperoxides

Peroxides can be removed from a solvent by passing it through a column of basic activated alumina, by treating it with indicating Molecular Sieves®, or by reduction with ferrous sulfate. (These procedures do not remove dialkyl peroxides, which may also be present)

6.6.10 Metal Hydrides

Most metal hydrides react violently with water with the evolution of hydrogen, which can form an explosive mixture with air. Some are pyrophoric. Most can be decomposed by gradual addition of methyl alcohol, ethyl alcohol, n-butyl alcohol, or t-butyl alcohol to a stirred, ice-cooled solution or suspension of the hydride in an inert liquid, under nitrogen. Although these procedures reduce the hazard of reactive metal hydrides, the products from such deactivation may be hazardous waste that must be treated as such on disposal.

6.6.11 Inorganic Cyanides

Inorganic cyanides can be oxidized to cyanate using aqueous hypochlorite. Hydrogen cyanide can be converted to sodium cyanide by neutralization with aqueous sodium hydroxide, and then oxidized.


6.6.12 Metal Azides

Heavy metal azides are explosive and should be handled by trained personnel. Sodium azide is explosive only when heated to near its decomposition temperature (300°C), thus heating it should be avoided. Sodium azide should never be flushed down the drain since the azide can react with lead or copper in the drain lines to produce an azide that may explode. Azides can be destroyed by reaction with nitrous acid.

6.6.13 Alkali Metals

Alkali metals react violently with water, common hydroxylic solvents, and halogenated hydrocarbons. The metals are usually destroyed by controlled reaction with an alcohol. The final aqueous alcoholic material can usually be disposed of in the sanitary sewer.

The Environmental Service Facility is able to redistill acetone, and methanol solvents for reuse. UBC’s solvent recovery program operates spinning band distillation units, which can provide labs with re-distilled solvents of high purity (purity analysis is provided upon request). For more information on the Solvent Recovery Program, call (604) 822-1285.

6.7.1 Procedures

Segregate and collect each solvent in its own UBC waste solvent containers, typically these are plastic red “Jerry” cans.

Do not mix two different solvents together. Use only containers that have been used for the same solvent stream. Do not mix oil with solvents. Do not pour sludge, grit, paper, or inorganic chemicals, into the waste solvent. Complete the required information and affix the generator bar code to the Solvents -

Recovery Tag (Green). Give a brief history of the solvent. Identify all contaminants. Affix the tags to the containers.

Ensure all caps are tightened before placing the containers in the designated waste disposal site for pick-up by ESF.

6.7 ORGANIC SOLVENTS FOR RECOVERY

http://www.chem.ubc.ca/safety/safety_manual/waste_designated_location.shtmlhttp://www.chem.ubc.ca/safety/safety_manual/waste_designated_location.shtml


Figure 4 - A bar code for disposal tags

NOTE:

A research group that is generating waste solvents must register with the Environmental Service Facility: (2-6306).

The research group will be provided with tags and barcode labels.

The barcode on each label is a unique “generator number” assigned to that research group.

The group is responsible for applying the barcode label to the area marked “GENERATOR COMPLETE THIS SECTION ONLY” on the tag.

Figure 5 - Solvent Recovery Tag

Most chemicals that are used in research and teaching laboratories are stable and non-explosive at the time of purchase. Over time, some chemicals can oxidize, become contaminated, dry out, or otherwise destabilize to become Potentially Explosive Chemicals (PEC) (e.g., isopropyl ether, sodium amide, and picric acid). PECs are particularly dangerous because they may explode if they are subjected to heat, light, friction, or mechanical shock. For PECs disposal, the UBC campus uses an off-campus contractor. The special care and procedures required for these chemicals result in high disposal costs - $600 or more for each container.

6.8.1 Picric Acid

dry picric acid is a highly explosive material order minimum amounts store with at least 10% moisture content; bottles containing less than 10% water should be

considered shock sensitive and highly explosive inspect monthly to ensure moisture level is maintained

6.8 POTENTIALLY EXPLOSIVE CHEMICALS


never shake a bottle of picric acid solution must not be allowed to accumulate and dry around the container cap threads contact the Safety Office for disposal of old stocks if you detect dry material accumulation contact the department safety office to arrange for

special waste disposal.

Do not send unknown chemicals to the Environmental Services Facility. Store the chemicals in secured space until identified. Call Chemistry Safety Program Administrator 7-5216 to arrange for identification and disposal of unknown chemicals. There will be a charge for identification / disposal of these chemicals.

6.10.1 Mercury Thermometers (Unbroken or Waste)

No mercury has spilled and the thermometers are intact, put into a glass or plastic bottle. Label the bottle “Mercury Thermometers for Disposal”.

Complete waste inventory form http://www.hse.ubc.ca/cwif/ and wait for approval Post approved form on the container Take to the designated waste disposal site.

6.10.2 Broken Mercury Thermometers or Mercury Spills

Report the spill to a supervisor for further assistance. Evacuate all personnel from the area if spill is large, the room is small, and ventilation is

poor. If you are going to participate in the cleanup, wear appropriate personal protective

equipment such as lab coat, gloves (rubber, latex, or vinyl), plastic boot protectors, splash goggles and a half-mask respirator with an approved cartridge for mercury vapours (HAZMAT may determine that self-contained breathing apparatus may be required if spill is large, temperature is elevated, and/or site of spill is in an enclosed space with poor ventilation). Note: you must have completed the annual fit test, and received the proper training in order to wear a respirator.

Ventilate area as much as possible (i.e. open all windows). Mark off spill area with signs, barriers, or tape. If spill is on a flat, even, smooth surface, use two pieces of firm, straight edge paper, (e.g.

copying paper) or plastic and slowly guide the droplets together into a pool. Use a glass pipette with rubber ball to suck up the mercury and collect it in the smallest

possible size bottle (glass or plastic) with a tightly fitting lid. Label the bottle “Mercury Waste.”

For picking up tiny droplets on uneven surfaces, use Merconvap wipes. For tiny droplets in cracks, pieces of metallic zinc rinsed in 10% HCl can be used. Run the zinc along the cracks
