1.0 INTRODUCTION

1.1 NWT Abandonment Program

The NWT well abandonment program consists of the abandonment of O-15, B-41, N-65, C-02 and N-65 wells in accordance with the Office of the Regulator of Oil and Gas Operations – NWT (OROGO) requirements. Permanent bridge plugs and cement will be used to isolate the downhole zones and the casing will be cut & capped one meter below ground level.

1.2 Purpose and Scope of the Environmental Protection Plan

Due to the limited nature and short duration of these operations and their relatively low environmental impact, this document reflects the scale of the operations.

The sections of the above document that are relevant to the operations planned for the well abandonment and equipment removal (e.g. waste management, fundamental mitigation measures, etc.) have been incorporated in this document to create a field site-specific reference.

This NWT Abandonment Program Environmental Protection Plan (EPP) is a component of the Paramount Operational Excellence Management System (POEMS), which is required to fulfill regulatory requirements. Paramount’s NWT EPP Program is developed and maintained, implemented and improved according to the POEMS (Management System). The POEMS sets procedures for how activities will be carried out while, at the same time, ensuring compliance with requirements for safety, environmental protection and conservation of resources.

The POEMS addresses the items listed below.

a) the policies on which the system is based;b) the processes for setting goals for the improvement of safety, environmental protection and

waste prevention;c) the processes for identifying hazards and for evaluating and managing the associated risks;d) the processes for ensuring that personnel are trained and competent to perform their duties;e) the processes for ensuring and maintaining the integrity of all facilities, structures,

installations, support craft and equipment necessary to ensure safety, environmentalprotection and waste prevention;

f) the processes for the internal reporting and analysis of hazards, minor injuries, incidents andnear-misses and for taking corrective actions to prevent their recurrence;

g) the documents describing all management system processes and the processes for makingpersonnel aware of their roles and responsibilities with respect to them;

h) the processes for ensuring that all documents associated with the system are current, validand have been approved by the appropriate level of authority;

i) the processes for conducting periodic reviews or audits of the system and for taking corrective actions if reviews or audits identify areas of non-conformance with the system andopportunities for improvement;

j) the arrangements for coordinating the management and operations of the proposed work oractivity among the owner of the installation, the contractors, the operator and others, asapplicable; and


3

k) the name and position of the person accountable for the establishment and maintenance of the system and of the person responsible for implementing it.

1.3 Responsibilities and Roles

Roles associated with the Liard abandonment program are presented in Table 1. The President and Chief Operating Officer of Paramount ultimately is accountable for the program. The Environmental Coordinator is responsible for development and maintenance of the NWT EPP Program and assists with implementation, though it is the Managers of the Drilling and Operations departments that are responsible for implementation. The Onsite HSE advisor will be responsible for the NWT EPP Program field implementation. The region Vice President (VP), is the President’s designate for the Liard area. As such, the VP is responsible for working with the Environmental Coordinator and Managers of the Drilling and Operations departments to ensure that the Liard EPP Program is being implemented and, if not, for ensuring issues are addressed. If necessary, the VP will request assistance from the President.

2.0 HAZARD REVIEW

2.1 A Summary of Studies Undertaken to Identify Environmental Hazards and to Evaluate Risks Relating to the Proposed Work or Activity

A detailed review of the environmental impacts associated with, or potentially associated with all of the activities in the Liard area was performed for the Mackenzie Valley Environmental Impact Review Board (Review Board). A review of the environmental assessment (EA) of the Ranger Oil Limited, Canadian Forest Oil Ltd., and Chevron Canada Resources Limited Integrated P‐66A/N‐61/K‐29 Gas Wells and Pipeline Tie‐in Fort Liard, NWT development proposal was performed, according to the requirements of Part V of the Mackenzie Valley Resource Management Act (MVRMA). http://reviewboard.ca/registry/ea99‐00610086 The development proposal consisted of two gas wells, one produced water injection well, a sour gas pipeline, a produced water pipeline (in a common trench with the gas line), an all season road, and all construction and operation activities associated with the road and the wells. The potential for two more gas wells, sour gas and water pipeline connections, and associated construction and operation activities were also considered. The Review Board reviewed and considered all information provided by the developer, expert advisors, regulatory authorities and the public in conducting the EA. Having considered all the evidence, the Review Board decided according to paragraph 128(1) (b) (ii) of the MRVMA to recommend approval of the development proposal subject to fourteen measures six of which are meant to mitigate potential adverse impact upon the environment. Those that are relevant to the work planned are addressed below. Environmental Impacts Specific to Abandonment

1. Extent if Physical Footprint - This project will use the existing wellsite and winter roads. If a camp is required, it will be located on an existing camp disturbance.

The recommendations and requirements of the Land Use Permit will be followed, along with good environmental and industry practices. Environmental risk or effect from this project: Potential effects of the proposed work or activity on extent of physical footprint is predicted to have a negligible environmental consequence because there will be no new surface disturbance required for this specific project. Paramount will ensure good environmental and industry practices are followed

2. Water Quality - The Review Board recognized previous public concern with the potential for contaminated emissions, including sedimentation, to water. The Review Board recommends that best industry practices be followed to ensure that such emissions are minimized. Environmental risk or effect from this project: A potential environmental hazard from the project is water contamination from a surface spill. Surface water effects are predicted to have a low environmental consequence because there will be no additional disturbance. Operations will be conducted in the winter, when

http://www.reviewboard.ca/upload/project_document/1305583337_Report_of_Environm

cleanup of any spill will be facilitated prior to any contaminant entering the watershed. Groundwater effects are predicted to be negligible. Paramount has in place an emergency response plan to respond to, report on and clean-up any spills of chemicals, fuels or other harmful substances. Paramount will follow best industry practices to ensure that such emissions are minimized.

3. Air Quality - No flaring is planned as part of the project. A small low pressure, sweet gas head will likely be present in the casing and this will be vented as part of the well kill procedure at the beginning of operations. There is no H2S associated with this well. Environmental risk or effect from this project: There is negligible risk of air contamination due to the nature of the well and the planned operations.

4. Wildlife - Due to the short duration of the project, long term wildlife data collection, monitoring and cumulative effect assessment are not appropriate. Environmental risk or effect from this project: Effects to wildlife habitat are predicted to be negligible due to the fact there will be no increased land disturbance and the proposed work is of short duration.

5. Suspension and Restoration - Immediate activities are the abandonment of five wells. Removal of surplus equipment will occur, and reclamation may occur as part of this program Environmental risk or effect from this project: Effects from this project are predicted to be negligible due to the fact there will be no additional disturbance for the proposed work or activity, beyond the existing wellsite and access roads.

6. Flaring – No flaring is anticipated in this operation Environmental risk or effect from this project: No air quality environmental consequences caused by flaring are anticipated from this project.

2.2 A Summary of the Measures to Avoid, Prevent, Reduce or Manage Environmental Risks

The Review Board EA identified measures to avoid, prevent, reduce or manage environmental risks (see summary below). Through the EA, development in the Liard area in the foreseeable future was approved subject to fourteen measures, six of which are meant to mitigate potential adverse impact upon the environment. The measures to avoid, prevent, reduce or manage environmental risks presented in the EA recommended by the MVEIRB have been incorporated into the Liard EPP Program manual. Pertinent sections of the manual are:

• Appendix 1: Fundamental Mitigation (including existing guidelines, best management practices and corporate procedures referenced therein); and

• Appendix 2: Task-specific Mitigation (including existing guidelines, best management practices and corporate procedures referenced therein).

3.0 APPLICABLE PROCEDURES

3.1 Critical Structures, Facilities, Equipment & Systems

Structures, facilities, equipment and systems critical to environmental protection are listed in Table 2. Systems in place for their inspection, testing and maintenance include:

• CAODC Service Rig Inspection Form: This industry standard form is used to verify correct and safeinstallation of the service rig. It is completed after rig up and prior to the commencement of operations

• Snubbing equipment is operated and maintained in accordance with DACC IRP #14 (as applicable).

• Boilers and well testing equipment comply with ABSA and BC Safety Authority and are manufacturedin accordance with ASME requirements.

• Fluid storage tanks (excluding small rig tank) are provided with secondary containment and inspectedregularly for leakage

Table 2: List of Structures, Facilities, Equipment and Systems Critical to Environmental Protection

Structure, Facility,Equipment or System

Blow-out Prevention and related systems

Boilers

Containment Tanks

Completion fluid system

Shut down devices

Function

Blow-out prevention and related systems are designed to control underground pressure that has the potential to reach the surface and cause a blow-out.

A closed pressure vessel with a furnace to burn coal, oil, or gas, used to generate steam from water.

A secondary containment system designed to contain leakage and prevent it from impacting the surrounding environment.

The main functions of completions fluids include providing hydrostatic pressure to prevent formation fluids from entering the well bore, keeping the mill cool and clean during milling of cement and mechanical plugs, carrying out cuttings and suspending the cuttings while milling is paused, and the assembly is brought in and out of the hole. The completion fluid used for a particular job is selected to avoid formation damage and to limit corrosion.

Because of the size, speed, and risk involved in the use of rig assist snubbing units and service rigs, safety shutdown systems are used to stop pipe rotation in an emergency

3.2 Chemical Selection

The only “process chemical” or “drilling fluid agent” that will be used in this program is Class G Oilwell cement.Although not currently programmed, it is possible that 15% Hydrochloric acid may be needed to facilitate cement squeezing. In that case, "soda ash" (Na2CaO3) will also be required to neutralize any live acid returns. These products are routinely used in the industry and established supplier's operational and safety procedures will be followed.

3.3 Waste Management

A description of equipment and procedures for the treatment, handling and disposal of waste material is provided in 3.3.1 and Table 3 below (extracted from Paramount's Corporate Procedures Waste Management Plan).

3.3.1 Discharge Streams

Discharge streams into the natural environment resulting from the NWT Abandonment program are limited to minor air emissions (venting of head gas in casing). Any significant trapped gas will be flared. Discharge limits for grey & black water are not presented because the onsite supervisor trailer will be self-contained and there will be no discharge of any waste. Completions fluids (containing cement / bridge plug milling solids), will be hauled to the nearest approved Class II Landfill in British Columbia or Alberta.

4.0 MONITORING COMPLIANCE

4.1 Monitoring Compliance with the EPP

Paramount’s NWT EPP Program is developed and maintained, implemented and improved according to the P OEMS. With respect to monitoring compliance with the NWT Abandonment EPP Program, the POEMS requires regular inspections by Field Supervisors and Managers, an annual audit of the POEMS and an evaluation of Environmental Protection targets through environmental indicators. A summary of inspections, audits and indicators is provided in the subsequent sub-sections and full details can be found in section 3 of the POEMS

4.1.1 Inspections

Inspections are designed to ensure that Field Supervisors and Managers make consistent checks of key components in their work areas and foster good working habits. Paramount maintains procedures for inspections and for establishing and maintaining records of the results. Further information on inspections is provided in section 3 of POEMS.

4.1.2 NWT POEMS Audit

An annual POEMS audit, conducted by the HSE department is required to examine the overall implementation of the POEMS.

4.1.3 Improvement

Environmental indicators help answer the question, “Were the targets met?” Environmental data is collected, validated and presented annually by the Environmental Coordinator, allowing the review and modification of objectives/targets. Paramount will record the extent to which planned objectives and performance criteria have been met and report to the corporation as a whole. The information may be made available to the public.


14

APPENDIX 1: FUNDEMENTAL MITIGATION Fundamental mitigation includes essential measures to eliminate, or at least minimize, negative impacts to air, water, land, and terrestrial species and aquatic species during all activities undertaken as part of the NWT abandonment Project. Note: Only those measures the may apply to the planned operations have been included.

a. LAND AND TERRESTRIAL SPECIES Mitigation measures to minimize negative effects to land and terrestrial species are included in the existing guidelines, best management practices and corporate procedures. Project-specific mitigation measures to minimize negative effects to land and terrestrial species are categorized and listed alphabetically below.

ACCESS MANAGEMENT

Motorized vehicles will travel on approved routes. The use of pipeline ROWs and the creation of ancillary access will be minimized. The recreational use of all-terrain vehicles (ATVs) and snowmobiles by construction personnel will not be permitted in the project area.

BORROW PITS

A Territorial Quarrying Regulations Quarry Permit from INAC is required to construct a borrow pit. Borrow pits will be re contoured to a stable profile (e.g. back sloped to a slope ratio not less than 3:1) and the salvaged topsoil / organic material replaced

CLEANUP Good housekeeping will be practiced. The target date for final cleanup will be immediately after the project is complete, when feasible, or as directed by the Land Use Inspector

EQUIPMENT MAINTENANCE – INVASIVE SPECIES

Construction and reclamation equipment (i.e., equipment used to “break ground”) will be cleaned before entering the Fort Liard, NWT Project area to ensure weed free condit ions. Similarly, materials such as pipe should be sourced from storage yards free of weeds. Equipment passing through areas identified as having a weed problem will be cleaned (e.g., steam/high pressure water, compressed air, etc.) prior to continuing work.

SNOW CLEARING To minimize impact on wildlife species abundance, snow removal will be limited to only that necessary for safe and efficient work.

SOIL CONSERVATION – FROST DEPTH

On work areas free of timber, snow will be packed onto the rough, natural surface with light-weight tracked vehicles to drive frost into the ground. To achieve sufficient snow-pack depth, thus a protective surface barrier, corduroy may be added to the snow. As well, water may be used to build-up the protective surface barrier. When working on wet, muskeg or permafrost terrain, ensure sufficient frost penetration is present to avoid terrain damage. Recommended minimum frost


15

depths are: (w) muskeg – 45 cm; (x) loam soils – 15 cm; (y) saturated silts or clays – 30 cm; and (z) sloughs or shallow water – 90 cm Erosion will be mitigated in areas disturbed by Project activities by various methods, as appropriate (e.g., check dams, contouring, cross ditches, cross berms, ditch plugs, diversion berms, positive drainage, seeding, silt fence, slash rollback, swales, etc.).


16

b. LAND USERS Project-specific mitigation measures to minimize negative effects to land users are listed below.

TRAPPERS

The appropriate the appropriate government and indigenous representatives will be notified by Paramount of the construction schedule as soon as the schedule is determined. Ideally, this should be at least two (2) weeks prior to approved clearing. If possible, arrangements will be made to have the trap line owners clearly identify trapping access routes and equipment (e.g., remove their traps and snares, etc.) in the vicinity of the right of way prior to clearing to ensure that they are protected during construction.

TRAILS Trails will not be blocked.

c. WILDLIFE AND WILDLIFE HABITAT Mitigation measures to minimize negative effects to wildlife and wildlife habitat are included in the existing guidelines and best management practices presented in the bulleted list below.

• GNWT. 2017. Safety in Grizzly and Black Bear Country. Department of Environment and Natural Resources.

• Canadian Pipeline Environment Committee. 2004. The pipeline industry and the Migratory Birds Convention Act.

Project-specific mitigation measures to minimize negative effects to wildlife and wildlife habitat are categorized and listed alphabetically below.

AVOIDANCE

Vehicle and equipment operators will be instructed to maintain appropriate speeds and to be aware of potential encounters with wildlife. If wildlife is encountered, it will not be fed or harassed and will be given an opportunity to disperse at its own rate. Pet dogs will be prohibited.

DENS / NESTS Dens and nests, even if inactive, will not be knowingly disturbed if it can be avoided.

HUNTING Project personnel are forbidden to carry firearms (except with written permission from Paramount) and to hunt.

REPORTING

Any incidents with nuisance wildlife or collisions with wildlife will be reported to GNWT, ENR. In the event that bear dens are encountered within the Project area, GNWT, ENR will be notified.

SNOW MANAGEMENT -

WINDROWS

Should snow be removed from access corridors, windrows at the edges of the road will be constructed. The windrows will have gaps (8 m) at regular intervals (every 300 to 500 m) to allow animal movement and to provide escape routes.


17

d. SPECIES AT RISK OR SPECIES OF SPECIAL STATUS AND RELATED HABITAT Project-specific mitigation measures to minimize negative effects to species at risk are categorized and listed alphabetically below. CARIBOU Existing Disturbance: Paramount will integrate new development with other

existing and/or planned activities, such as using existing clearings, common corridors, parallel corridors, etc. to the extent practicable.

Timing: Late winter and spring are the times of year when caribou (especially pregnant cows) are most likely to be negatively affected by human activity. Therefore, Paramount will adopt an “early in, early out” philosophy for winter development activity.

Noise: Paramount will minimize extraneous noise sources and use adequate noise attenuation on engines.

Line-of-Site: For any new access, Paramount will minimize lines- of-site from access roads using “dog-legs” (see figure below) or other techniques.

Source: Yukon Energy, Mines and Resources (2006)

Access Management: Paramount will create barriers (e.g. felled trees, signage, etc.) to discourage access from roads to pipeline rights-of-way and seismic lines.


18

Support Other Initiatives: The following initiatives will support the Action Plan: Boreal Woodland Caribou Conservation in the Northwest Territories 2010–2015 (Prepared by GNWT – ENR):

Paramount will continue to track its footprint by making available “as-built” maps of the Fort Liard Project area.

Paramount, among other partners, is supporting scientific research entitled, “Development of ecologically-based criteria to assess the impact and recovery of seismic lines”, which is being conducted by Dr. Erin Bayne, Assistant Professor with the Integrated Landscape Management Group at the University of Alberta.

WOLVERINE To mitigate potential impacts to wolverine, Paramount will scout sites prior to undertaking activities that may impact active natal denning habitat. In the event that wolverines or active natal denning habitat is observed near sites, activity will be minimized so as not to disturb the animals and the appropriate authorities will be notified.


19

e. WATER AND AQUATIC SPECIES Mitigation measures to minimize negative effects to water and aquatic species are included in the existing guidelines and best management practices presented in the bulleted list below.

• DFO Protocol for Water Withdrawal for Oil & Gas Activities in the Northwest Territories and Changes to DFO Protocol for Winter Water Withdrawal in the NWT, except where terms and conditions for withdrawal are already in place (i.e., existing Water Licences).

• DFO (Fisheries and Oceans Canada). 1995. Freshwater Intake End-of-Pipe Fish Screen Guidelines

Project-specific mitigation measures to minimize negative effects to water and aquatic species are categorized and listed alphabetically below.

FOREIGN MATERIAL Trees will not be purposely felled into water bodies. Likewise, slash, debris, rocks and soil will not be knowingly introduced into a water body.

GRADING Grade away from watercourses to minimize introduction of soil and organic debris. No windrowed or fill material shall be placed in the watercourses during grading.

GROUNDWATER If water wells are used, care will be taken to ensure water withdrawal is completed at a rate to protect water well integrity

SETBACK DISTANCES

Paramount will observe setback distances of 100m from the edge of a disturbance to the edge of a watercourse / water body, except when a watercourse / water body is being crossed (see DFO Northwest Territories Operational Statements). Where necessary, alternative setbacks will be determined through consultation with the MVLWB.

WETLAND RESTORATION

Wetlands will be restored to approximate their pre-construction profile. Revegetation will be through natural encroachment. Peatland areas will not be seeded or fertilized.

WATER WITHDRAWL FROM

WATERCOURSES

Water will be withdrawn from watercourses, as per DFO Northwest Territories Operational Statements:

• the withdrawal of any water will not exceed 10% of the instantaneous flow, in order to maintain existing fish habitat and

• water flow is maintained under the ice, where this naturally occurs. Reference Yukon Energy, Mines and Resources. 2006. Oil & Gas Best Management Practices Seismic Exploration. 37pp. Available online at: http://www.emr.gov.yk.ca/oilandgas/pdf/bmp_seismic.pdf


20

APPENDIX 2: TASK SPECFIC MITIGATION Task‐specific mitigation includes essential measures to eliminate, or at least minimize, negative impacts to air; land and terrestrial species and water and aquatic species during specific activities undertaken as part of the NWT Abandonment Project.

a. TEMPORARY CAMPS Project-specific mitigation measures to minimize negative effects to the environment associated with temporary camps are categorized and listed alphabetically below.

LOCATION Campsites will coincide with previously cleared land, or natural clearings, on relatively level terrain 100m from any watercourse, where possible. No new campsites are planned.

CONSTRUCTION

Depending on the infrastructure required (e.g., trailers, sewage sumps, welding shop, vehicle parking, etc.), an area 40m x 70m to 100m x 100m will be cleared for temporary camps. Slash will be windrowed at the camp boundaries and used for rollback during site reclamation. Snow will be used to level minor irregularities on the surface as much as possible. Vehicles will be used to compact the insulating snow cover to promote deep frost penetration.

EROSION PREVENTION

Site stability at temporary campsites will be assessed within one year after construction. If unstable, appropriate corrective action will be undertaken as soon as practical to stabilize the site, thereby minimizing erosion.

SECTION 4: FIRST AID MEASURES Description of First Aid Measures General: Never give anything by mouth to an unconscious person. If you feel unwell, seek medical advice (show the label if possible). Inhalation: When symptoms occur: go into open air and ventilate suspected area. Keep at rest and in a position comfortable for breathing. If you feel unwell, seek medical advice. Skin Contact: Remove contaminated clothing. Immediately flush skin with plenty of water for at least 60 minutes. Immediately call a POISON CENTER or doctor/physician. Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing for at least 60 minutes. Immediately call a POISON CENTER or doctor/physician. Ingestion: Rinse mouth. Do not induce vomiting. Immediately call a POISON CENTER or doctor/physician.

Most Important Symptoms and Effects Both Acute and Delayed General: Corrosive to eyes, respiratory system and skin. Exposure may produce an allergic reaction.


04/23/2015 EN (English US) 3/11

Inhalation: The three types of silicosis include: 1) Simple chronic silicosis – which results from long-term exposure (more than 20 years) to low amounts of respirable crystalline silica. Nodules of chronic inflammation and scarring provoked by the respirable crystalline silica form in the lungs and chest lymph nodes. This disease may feature breathlessness and may resemble chronic obstructive pulmonary disease (COPD); 2) Accelerated silicosis – occurs after exposure to larger amounts of respirable crystalline silica over a shorter period of time (5-15 years); 3) Acute silicosis – results from short-term exposure to very large amounts of respirable crystalline silica. The lungs become very inflamed and may fill with fluid, causing severe shortness of breath and low blood oxygen levels. Inflammation, scarring, and symptoms progress faster in accelerated silicosis than in simple silicosis. Progressive massive fibrosis may occur in simple or accelerated silicosis, but is more common in the accelerated form. Progressive massive fibrosis results from severe scarring and leads to the destruction of normal lung structures. Some studies show that exposure to respirable crystalline silica (without silicosis) or that the disease silicosis may be associated with the increased incidence of several autoimmune disorders such as scleroderma (thickening of the skin), systemic lupus erythematosus, rheumatoid arthritis and diseases affecting the kidneys. Silicosis increases the risk of tuberculosis. Some studies show an increased incidence of chronic kidney disease and end-stage renal disease in workers exposed to respirable crystalline silica. Corrosive to the respiratory tract. Skin Contact: Cement may cause dry skin, discomfort, irritation, severe burns, and dermatitis. Exposure of sufficient duration to wet cement, or to dry cement on moist areas of the body, can cause serious, potentially irreversible damage to skin, eye, respiratory and digestive tracts due to chemical (caustic) burns, including third degree burns. A skin exposure may be hazardous even if there is no pain or discomfort. Cement is capable of causing dermatitis by irritation and allergy. Skin affected by dermatitis may include symptoms such as, redness, itching, rash, scaling, and cracking. Irritant dermatitis is caused by the physical properties of cement including alkalinity and abrasion. Allergic contact dermatitis is caused by sensitization to hexavalent chromium (chromate) present in cement. The reaction can range from a mild rash to severe skin ulcers. Persons already sensitized may react to the first contact with cement. Others may develop allergic dermatitis after years of repeated contact with cement. Eye Contact: Airborne dust may cause immediate or delayed irritation or inflammation. Eye contact with large amounts of dry powder or with wet cement can cause moderate eye irritation, chemical burns and blindness. Eye exposures require immediate first aid and medical attention to prevent significant damage to the eye. Ingestion: May cause burns or irritation of the linings of the mouth, throat, and gastrointestinal tract. Chronic Symptoms: If dust is generated, repeated exposure through inhalation may cause cancer or lung disease.

Indication of Any Immediate Medical Attention and Special Treatment Needed If exposed or concerned, get medical advice and attention.

SECTION 5: FIRE-FIGHTING MEASURES Extinguishing Media

Special Hazards Arising From the Substance or Mixture

Advice for Firefighters Precautionary Measures Fire: Exercise caution when fighting any chemical fire. Firefighting Instructions: Do not get water inside containers. Do not apply water stream directly at source of leak. Protection During Firefighting: Do not enter fire area without proper protective equipment, including respiratory protection. Hazardous Combustion Products: None.

Reference to Other Sections Refer to section 9 for flammability properties.

SECTION 6: ACCIDENTAL RELEASE MEASURES Personal Precautions, Protective Equipment and Emergency Procedures

General Measures: Do not breathe dust. Do not get in eyes, on skin, or on clothing. For Non-Emergency Personnel Protective Equipment: Use appropriate personal protection equipment (PPE). Emergency Procedures: Evacuate unnecessary personnel.

Suitable Extinguishing Media: Use extinguishing media appropriate for surrounding fire. Unsuitable Extinguishing Media: Do not use a heavy water stream. Use of heavy stream of water may spread fire.

Fire Hazard: Not flammable. Explosion Hazard: Product is not explosive. Reactivity: Wet cement is alkaline and is incompatible with acids, ammonium salts and aluminum metal. Cement dissolves in hydrofluoric acid, producing corrosive silicon tetrafluoride gas. Cement reacts with water to form silicates and calcium hydroxide. Silicates react with powerful oxidizers such as fluorine, boron trifluoride, chlorine trifluoride, manganese trifluoride, and oxygen difluoride.


04/23/2015 EN (English US) 4/11

For Emergency Personnel Protective Equipment: Equip cleanup crew with proper protection. Emergency Procedures: Ventilate area.

Environmental Precautions

Prevent entry to sewers and public waters.

Methods and Material for Containment and Cleaning Up

For Containment: Place spilled material into a container. Avoid actions that cause the cement to become airborne. Avoid inhalation of cement and contact with skin. Wear appropriate protective equipment as described in Section 8. Scrape wet cement and place in container. Allow material to dry or solidify before disposal. Do not wash cement down sewage and drainage systems or into bodies of water (e.g. streams). Methods for Cleaning Up: Avoid actions that cause dust to become airborne during clean-up such as dry sweeping or using compressed air. Use HEPA vacuum or thoroughly wet with water to clean-up dust. Use PPE described in Section 8.

Reference to Other Sections See heading 8, Exposure Controls and Personal Protection. Concerning disposal elimination after cleaning, see item 13.

SECTION 7: HANDLING AND STORAGE Precautions for Safe Handling Additional Hazards When Processed: Keep bulk and bagged cement dry until used. Stack bagged material in a secure manner to prevent falling. Bagged cement is heavy and poses risks such as sprains and strains to the back, arms, shoulders and legs during lifting and mixing. Handle with care and use appropriate control measures. Engulfment hazard. To prevent burial or suffocation, do not enter a confined space, such as a silo, bin, bulk truck, or other storage container or vessel that stores or contains cement. Cement can buildup or adhere to the walls of a confined space. The cement can release, collapse or fall unexpectedly. Properly ground all pneumatic conveyance systems. The potential exists for static build-up and static discharge when moving cement powders through a plastic, non-conductive, or non-grounded pneumatic conveyance system. The static discharge may result in damage to equipment and injury to workers. Cutting, crushing or grinding hardened cement, concrete or other crystalline silica-bearing materials will release respirable crystalline silica. Use all appropriate measures of dust control or suppression, and Personal Protective Equipment (PPE) described in Section 8 below. Hygiene Measures: Handle in accordance with good industrial hygiene and safety procedures. Wash hands and other exposed areas with mild soap and water before eating, drinking, or smoking and again when leaving work. Wash contaminated clothing before reuse.

Conditions for Safe Storage, Including Any Incompatibilities Storage Conditions: Store in a dry, cool and well-ventilated place. Keep container closed when not in use. Incompatible Materials: Wet cement is alkaline and is incompatible with acids, ammonium salts and aluminum metal. Cement dissolves in hydrofluoric acid, producing corrosive silicon tetrafluoride gas. Cement reacts with water to form silicates and calcium hydroxide. Silicates react with powerful oxidizers such as fluorine, boron trifluoride, chlorine trifluoride, manganese trifluoride, and oxygen difluoride. Storage Temperature: Unlimited

Specific End Use(s) Cement is used as a binder in concrete and mortars that are widely used in construction. Cement is distributed
