WELDING,CUTTING,HOT WORK ❑General safe work practices:
<br /> (GAS OR ARC) . Hot work permit system to be implemented.
<br /> UV/IR light-eye/skin burns,hot-work . Operator properly protected(eye protection,clothing,apron,etc.).
<br /> hazards,toxic welding fumes, . Fire hazard controls(watcher,fire extinguisher,water,isolate combustibles).
<br /> compressed gases,electrical shock . Protect nearby personnel from hazardous UV,IR light(shielding,curtain).
<br /> ❑For gas weld I ng/cutti ng,use gas cylinder safe practices(secured,upright,caps on when not in use,prevent
<br /> Damage;never secure gas cylinders to metal bench used for arc welding).
<br /> ❑For arc welding,follow electrical safe work practices.See Section 6.8.,"Electrical Hazards."
<br /> ❑See Section B.13.,"Commercial Chemical Products,"for hazards of welding rods(toxic metals),welding gases.
<br /> Geosyntec Procedure(s):HS-511-Welding,Cutting and Other Hot Work
<br /> COMPRESSED AIR,COMPRESSOR ❑Never direct nozzle toward body;do not use compressed air for cleaning clothes.
<br /> (for compressed gases,see ❑If compressed air is used for cleaning,restrict pressure to 30 psi or below,equip nozzle with chip guard.
<br /> Section 8.13.,"Compressed Gases") ❑Use eye protection.
<br /> ❑Ensure air tank,hoses,fittings are in good repair using factory fittings.
<br /> PORTABLE GENERATOR ❑Follow general safety practices for Operation of Equipment/Machinery(above),and as follows:
<br /> Hazards:Electrical shock,carbon • Use in accordance with manufacturer's instructions.
<br /> monoxide in exhaust,fuel-related • Keep generator and work area dry.
<br /> fire,injury from mechanical hazards, • Never use indoors,or near building air intake vents due to carbon monoxide hazard.
<br /> lifting • Provide for ventilation and/or air monitoring where hazardous accumulation of exhaust emissions is possible.
<br /> • Use hearing protection in close proximity to operating generator,as needed.
<br /> • Use power cords/extension cords specified by instructions.
<br /> • Use ground-fault circuit interrupters(GFCls)in accordance with manufacturer's instructions.
<br /> • See Section B.8.,"Electrical Hazards."
<br /> • Shut down equipment before refueling. See safe practices for flammable/combustible liquids in Section 8.13.,
<br /> "Commercial Chemical Products."
<br /> Geosyntec Procedures:HS-109-Hearing Conservation,HS-111-Air Monitoring,
<br /> HS-115-Hazard Communication(for fuel),HS-121-Electrical Safety,Others as applicable
<br /> PORTABLE HEATERS ❑Follow general safety practices for Operation of Equipment/Machinery(above),and as follows:
<br /> (electric or fuel powered) • Keep heater dry,and locate heater on level surface away from high traffic areas.
<br /> Hazards: I • Never use fuel-powered heaters indoors,or near air intake vents,due to carbon monoxide hazard.
<br /> Electric-powered: Electrical shock, • Provide for ventilation and/or air monitoring where hazardous accumulation of exhaust emissions is possible.
<br /> fires from hot surfaces. • Keep combustible materials at least 3 feet from hot surfaces.
<br /> Fuel powered:Carbon monoxide in • Do not use an extension cord or power strip to power an electric heater.
<br /> exhaust,fires from hot surfaces, • For electric heaters,See Section B.8.,"Electrical Hazards."
<br /> fuel-related fires • Shut down fuel-powered equipment before refueling. See safe practices for flammable/combustible liquids
<br /> and/or compressed gases in Section B.13.,"Commercial Chemical Products."
<br /> Geosyntec Procedures: HS-111-Air Monitoring,HS-115-Hazard Communication(for fuel,
<br /> HS-121-Electrical Safety,Others as applicable
