Young Worker Awareness
What's Safe? What isn't?
A perfectly safe and healthy workplace would have no hazards.
Hazard: any situation, condition or thing that may be dangerous to the safety or health of workers.
Unfortunately, many workplace hazards are so familiar that we ignore them and put ourselves, and sometimes others, at risk.
DID you know that most injuries among new workers happen within
the first year of work?
Young workers are at the greatest risk of getting injured during their first six months on the job.
Young men are more likely to be injured on the job than any other group of workers.
DID you know that most injuries among new workers happen within
the first year of work? Most injuries take place in the
service industry - to students and other young people working as waiters, cooks and store clerks
Do you know anyone that has been injured on the job?
What types of injuries can occur in the workplace?– Sprains and strains– Cuts– Broken bones– Loss of limbs– Crushing injuries– Internal organ damage– Eye injuries
What are some of the consequences of a workplace
injury. Short- and long-term disability Disfigurement Dismemberment Death

Lost Youth Video Quiz
1. Young workers have the same risk of injury on the job as other workers do.
❒ True ❒ False
False Young people between 15 and 24 years are particularly vulnerable to work-related injuries. They’re eager to please and have much to offer, but they typically lack the experience to judge what’s safe and what’s not.
Lost Youth Video Quiz
2. Only jobs in industries such as construction and forestry are dangerous for young workers.
❒ True ❒ False
False When people think about the risk of workplace injury, they assume it is pretty much limited to jobs in construction and manufacturing, and it’s true—these industries can be hazardous. However, most youth work in restaurants, supermarkets, and retail stores. are often shocked to hear that these are the sectors with the highest rate of injury to young workers.
Lost Youth Video Quiz
3. Injuries to young workers are often major ones.❒ True ❒ False
True Injuries to young workers do include minor strains, cuts, and bruises that heal quickly. But young workers also suffer from severe injuries—fractures and dislocations, for example—that result in short-term disability. Worst of all, young workers can and do suffer from very serious injuries such as amputations, broken backs, and third-degree burns. These injuries can mean permanent impairment, disfigurement, and disability
Lost Youth Video Quiz4. Young workers don’t have any health and safety
rights on the job—they can get fired for speaking up.
❒ True ❒ False
False All workers in Alberta are protected by the Workers Compensation Act . This legislation says employers must provide all employees with a safe workplace, adequate training and supervision, and properly maintained and functioning safety equipment. Workers also have the right to refuse work if they believe the task or conditions are unsafe. The Act also protects them from disciplinary action for reporting a safety or other work-related problem. Concerns can be reported anonymously to the WCB
Lost Youth Video Quiz5. Only the WCB can guarantee workplace
safety for young workers.❒ True ❒ False
False Keeping young workers safe is a shared responsibility. Employers, unions, co-workers, parents, educators, youth, the community, and the WCB all have a part to play.
Lost Youth Summary More than 50 percent of work-related
accidents happen during a young worker’s first six months on the job.
Males under 25 are much more likely to be injured on the job than any other workers.
Each day in Alberta., 34 young workers are hurt on the job, or one every 42 minutes.
Every week, five of these young workers are permanently disabled in workplace accidents.

Hazards in the Workplace
It is important to know what hazards are, and to know what your rights and duties are when you meet them.
Some hazards can cause an immediate injury.
Hazards in the Workplace For instance, you could slip and fall
on a wet or greasy floor, or be burned by a hot grill.
You could get splashed by a chemical, such as sulfuric acid or ammonia, and get a burn.
A fire or an explosion can cause serious injury or death.
Hazards in the Workplace Burns, cuts, muscle strains and broken
bones are acute injuries you can feel as soon as the accident happens.
Some hazards can cause you to become sick or injured over a period of time.
For instance, if you work with certain hazardous chemicals, the damage that happens in your body may not be noticed right away.
How do you find a hazard? Ask yourself what if questions... What if I bump into the open containers
of hot oil? What if the forklift tips over on my co-
worker in a fast turn? What if I inhale the toxic fumes from the
toilet cleaning chemicals? Learn to spot a hazard - before an
incident happens - is the first step to staying safe.
How do you find a hazard?
Every job will have slightly different hazards.
Wherever you work, there are 4 main types of hazards and some examples:
Physical hazards– Using the same tool all day long – Being crushed by equipment – Tripping or falling
How do you find a hazard?
Biological hazards– Bee stings – Allergic reaction to plants,
insects or mold – Being in contact with materials
where viruses or bacteria are present
How do you find a hazard?
Chemical hazards– Using cleaning products
regularly – Using paint materials regularly – Using toxic chemicals
How do you find a hazard?
Psychosocial Hazards– Intimidation, verbal abuse – Working hours – Rotating shift work
How do you find a hazard?
Ergonomic hazards– Repetitive motions– Overexertion– Awkward Postures

Three key steps that can be used to control a hazard:– Recognition
– Evaluation
– Control
Controlling a HazardSee it. Questions to ask: What is unsafe? How many unsafe
acts or conditions are there? What are the hazards?
Think it. Questions to ask: Why is it a hazardous situation?
What could happen? What is creating the hazard? What injuries could occur?
Do it. Questions to ask: What could be done to prevent an
accident from happening? What could minimize the risk? What could be done to eliminate or minimize the hazard?

WHMIS
WHMIS
WHMIS STANDS for Workplace Hazardous Materials Information System.
WHMIS is a nation-wide system that gives you the facts you need about the materials you handle in the workplace. WHMIS has three components: (1) Labels (2) Worker Education (3) Material Safety Data Sheets (MSDSs)
WHMIS Classes
WHMIS applies to materials called “controlled products”.
A controlled product is a product that meets the criteria for one or more of the six WHMIS hazard classes.
Each class, except Class D, has a separate “hazard symbol.
Class D has three hazard symbols — one for each of its divisions.
WHMIS Classes
Labels
There are two kinds of WHMIS labels — supplier labels and work site labels
Supplier labels appear on controlled products purchased from Canadian suppliers
Supplier labels provide basic information about how to handle a product safely.
Supplier labels have a distinctive rectangular slash-marked border.
Labels
Supplier labels contain 7 pieces of information: (1) product name;(2) name and address of the supplier (3) symbols for each of the product’s hazard
classes(4) main hazards of the product(5) precautions during handling and use of the
product(6) first aid measures(7) reference to the MSDS for more information
Labels
Labels
Work site labels appear on controlled products that have been transferred from suppliers’ containers to work site containers, or products where the supplier label may be damaged or missing and on controlled products made at the work site
LabelsWork site labels are less detailed than supplier labels and only require three pieces of information:
(1) name of the product;
(2) information on how to use the product safely; and
(3) reference to the MSDS for further information.
Labels
Material Safety Data Sheets
If you need to know more about a product than you can find on the label, go to the product’s MSDS.
These sheets have more detailed information about a product’s properties, its hazards, and how to prevent overexposure.
There is no specific required layout for the WHMIS MSDS, but it must include at least each of the nine categories of information and the required detailed information in each category.
Material Safety Data Sheets
Material Safety Data Sheets
An MSDS is supposed to be sent to an employer with every controlled product the employer buys.
MSDSs must never be more than three years old.
The MSDSs for all controlled products at a work site must be kept in a place where workers have easy access to them.
If you are a worker and don’t know where they’re kept, ask your supervisor.
Worker Education The third component of the system, Worker
Education, helps workers understand WHMIS information so they can work safely with controlled products.
This education explains the WHMIS system and gives workers specific training related to the controlled products they work with at their workplace .
Employers are required to provide worker education for WHMIS.
Worker Education
WHMIS worker education includes training workers to understand:
the information on WHMIS labels and MSDSs, the meaning of that information and its application to their work
identification systems that are used in place of labels at a work site
specific procedures for safe use, handling, storage and disposal of the controlled products that workers handle
Worker Education procedures for dealing with fugitive emissions of
the controlled products workers may encounter procedures for emergencies involving controlled
products.
The information taught in a WHMIS worker education program is important because it helps workers protect their health and safety at work.

Safe Shop Practices
Electrical Safety
Electricity may be supplied as 120 V or 240 V.
Tools and machines are designed to operate on only one specific voltage.
Serious damage and fire can result if you use the incorrect voltage.
Electrical Safety
An ungrounded electric power tool can lead to an electric shock and death if the current is high enough.
An electric power hand tool or stationary machine must be grounded.
Electrical Safety
Never remove the third prong to match a two slotted outlet.
Check the insulation on cords for breaks or cracks.
Never stand on wet ground or floor while using electric tools.
Air Power Safety
Compressed air is used for operating air tools, for spraying and cleaning.
Use a “safety blow” nozzle when cleaning with compressed air.
Air Power Safety
A “safety blow” nozzle reduces the air pressure so it wont be more than 30 psi.
Always check for damaged hoses or connections.
Air Power Safety
Do not turn the hose towards others or your own skin.
The air may have particles that will penetrate the skin.
Never use compressed air to clean metal fragments.
FuelHeat
Oxygen
Fire Safety
Fire can break out anywhere, including where you work.
Each year numerous fires in the workplace cause injury and property loss.
Employees should know ...
The location of two exits closest to their work area.
The location of the nearest fire alarm pull station and how to use it.
Your responsibilities in a fire, which are in the fire safety plan.
If You Discover a Fire
Activate the nearest fire alarm pull station.
Leave the area immediately, closing all doors behind you.
Go to the nearest exit and leave the building.
Close all doors behind you.
The Use of Extinguishers Most workplaces contain
portable fire extinguishers. Fire extinguishers can only
put out small, contained fires, such as a fire in a wastebasket.
If you have not been trained in the proper use of portable extinguishers, do not attempt to fight a fire.
Never fight a fire
If the fire is large or spreading.
If your escape route may be blocked by the spread of fire.
If you are not trained in the correct use of the extinguisher or are unsure of the type of fire.
Fire Prevention Tips for a Safer Workplace
No smoking in any shop areas. Check and replace any electrical cords that have
cracked insulation or broken connectors. Avoid octopus wiring. Do not run extension cords across doorways or
under rugs. Avoid plugging more than one extension cord into
an outlet. Use only CSA approved power tools.
Fire Prevention Tips for a Safer Workplace
Leave enough space for the circulation of air around heaters and other equipment such as welders and wood working machines.
Keep all power tools a safe distance from combustible materials.
Always turn off or unplug tools and machines at the end of each day.
Fire Safety Checklist RUBBISH - Dispose of daily; do not
allow unnecessary accumulation. FLAMMABLES - Store safely in proper
containers; no breaks, or spills. HOUSEKEEPING - Keep the work
area neat and clean. WIRING - Report or repair unsafe
conditions.
Fire Safety Checklist MACHINERY - Keep clean and in good
working order. COMBUSTIBLES - Keep well away from
sources of heat (at least 3 feet). VENTILATION - Ventilate waste and
high-fume areas. EXTINGUISHERS - Keep in place the
proper ones and mark them well if out of sight.
Fire Safety Checklist EXITS, PASSAGEWAYS - Keep clear,
unobstructed and unlocked! EVACUATION ALARM - Recognize it! EVACUATION PROCEDURES - Practice
and make sure everyone knows the procedures.
ELECTRICAL EQUIPMENT - Keep at a minimum clearance of at least 3 feet . Do not overload circuits.
