D.14. COMMERCIAL CHEMICAL PRODUCTS(per HAZCOM or WHMIS) Applicable Not Applicable, Not Anticipated Site-Specific Notes&Clarifications:Emissions from vehicles and/or heavy equipment PRODUCTS REGULATED BY i ❑Safety Data Sheets(SDSs)available,either on site or readily available within same work shift,containers HAZCOM'(US)or WHMISZ(CAN) labelled properly,workers trained/oriented on hazards. ❑For subcontractor/contractor use of chemical products,confirm SDS availability for affected onsite workers. ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 'OSHA Hazard Communication Standard(United States);7 Workplace Hazardous Material Information System(Canada) GENERAL SAFE WORK PRACTICES ❑Consult SDS for HSE hazards,symptoms of exposure;ensure workers have been apprised of safe practices. FOR FIELD USE OF CHEMICALS E ❑Handle with care,maintain good housekeeping,provide adequate illumination in work area. E ❑Pour/dispense/transfer liquid chemicals on stable work surface. E ❑Use chemicals in well-ventilated area;use fans/blowers/exhaust for active ventilation,as appropriate. ❑Have eyewash bottles,eyewash station,deluge capabilities,commensurate for the hazard,readily available. ❑Have spill/neutralization equipment,appropriate for the chemicals,readily available. E ❑Conduct air monitoring as appropriate;see Part E,"Air Monitoring,Worker Exposure Monitoring." STORAGE/TRANSPORT OF ❑Transport chemicals only in sealed containers,secured to prevent shifting/breakage during travel. CHEMICALS/HAZMAT E ❑Store chemicals only in sealed containers;overnight storage in squirt/spray bottles prohibited. ❑Non-Emergency(Routine) ElStore flammable/combustible liquids in chemical storage cabinets,or other appropriate storage arrangement. Chemical Storage Risk of personal ❑For liquids,provide secondary containment during storage. contact and/or incidental release E ❑Segregate incompatible chemicals during storage. El HAZMAT Transport ElFor incidental release/spill;maintain spill kit suitable for low flammability/toxicity/quantity/volatility release. E ❑DOT/TDG/IATA-Regulated transport:see D.17."Hazmat/Dangerous Goods Shipping/Transportation. ❑Risk of Emergency Spill/Release ❑For emergency spills:describe spill/release hazard and response plan/procedure above,and indicate ❑CFTAS(Chemical Facility Anti- emergency response contact in Part B,"Emergency Response and First Aid." Terrorism Standards)Applicability: ❑Locate emergency gear(eyewash,fire extinguisher,spill kit,safety signage)near storage area,as applicable. On-site overnight storage of non- ElFor CFTAS-applicable chemical storage,a safety and chemical management plan must be prepared and waste chemical product at quantity reviewed by a HSE Professional before bringing material to the site.(Does not apply to materials brought on to >25 gal(115L)or 2250 lbs.(115 kg) i the site for daily work purposes and transported away at the end of each day) COMPRESSED GAS CYLINDERS ❑Secure cylinders upright,caps on when not in use. ❑Flammable E ❑Handle with care;use and store cylinders in a manner and location to prevent damage. ❑Non-flammable ❑Propane cylinders not in use must be stored outdoors in a cage or similar secure ventilated enclosure. ❑Toxic ❑Ensure acetylene cylinders are NOT secured to steel arc welding bench. ❑Asphyxiant ❑Segregate oxygen and fuel gases by distance(20')or fire-rated barrier. ❑Oxygen ❑Control ignition sources. E ❑"No smoking"signage at cylinder storage area for flammable gases. FLAMMABLE/COMBUSTIBLE ❑Use proper fuel safety can(metal fuel container with self-closing spout and flame arrestor preferred). LIQUIDS E ❑Control/remove ignition sources near storage and use areas. ❑Grounding and bonding where appropriate. E ❑Ensure a Type B or ABC fire extinguisher is readily available. ACIDS,CAUSTICS,OTHER ❑Use appropriate protection for eyes/face(goggles/face shield)and skin(gloves,sleeves,apron). CORROSIVES E ❑Use eyewash,deluge shower,drench hose,hand washing(with water),as appropriate. ❑For severe eye hazards(due to high corrosivity,large quantity),15-min.eyewash required. TOXIC ❑For toxic substances,use/store in a manner to control exposure hazards(inhalation,ingestion,skin contact, skin absorption);use active ventilation and/or PPE as appropriate. ® EMISSIONS FROM FUEL ®Position outdoor personnel upwind of exhaust source. COMBUSTION,HOT PROCESSES E ®Avoid"idling"of equipment when not in use. ❑Gasoline ❑Use passive ventilation(air infiltration/air currents)to disperse atmospheric hazards in breathing zone. ❑Diesel ❑Use dilution ventilation(blowers/fans)to provide fresh air to work area and dissipate atmospheric hazards. ❑Propane/Natural Gas ❑Use exhaust ventilation(hood/duct/exhaust stack/blower)to capture/divert exhaust from work area. ❑Welding/cutting/hot work ❑Use respiratory protection for high levels of smoke,exhaust particulates,soot. ®Vehicle/equipment exhaust ❑Conduct air monitoring as appropriate;see Part E,"Air Monitoring,Worker Exposure Monitoring." ❑Other OTHER HAZARDS r ❑Describe other hazardous substances and safety measures under"Site-Specific Notes&Clarifications,"above.
