WELDING,CUTTING,HOT WORK ❑General safe work practices for operators of welding equipment:
<br /> ❑Arc-welding(electrical arc) • Hot work permit system to be implemented.
<br /> ❑Gas-welding/cutting(fuel gases) l • Operator properly protected(eye protection,clothing,apron,etc.).
<br /> Hazards: l • Fire hazard controls(watcher,fire extinguisher,water,remove combustibles from work area).
<br /> UV/IR light-eye/skin burns I • Protect nearby personnel from hazardous UV,IR light(shielding,curtain);see D.16."Radiation Hazards."
<br /> hot-work hazards/fire ❑For welding gas cylinders,secure them upright with caps on when stored or not in use;protect cylinders from
<br /> toxic metal welding fumes damage;NEVER secure gas cylinders to metal welding bench used for electrical arc welding);
<br /> compressed gases see D.14."Commercial Chemical Products."
<br /> electrical shock ❑For arc welding,follow electrical safe work practices;see D.30."Electrical Work Tasks."
<br /> ❑For inhalation hazards from welding fumes(toxic metals)and gases(asphyxiant,flammable),see D.14.
<br /> "Commercial Chemical Products."
<br /> Geosyntec Procedure(s):HS-511-Welding,Cutting and Other Hot Work
<br /> PORTABLE ELECTRIC GENERATOR l ❑Follow general safe work practices for Powered Tools&Equipment(above),and as follows:
<br /> Hazards: l • Use in accordance with manufacturer's instructions,including instructions for grounding the generator.
<br /> Electrical shock l • Keep generator and work area dry.
<br /> Carbon monoxide in exhaust I • Never use indoors,or near building air intake vents due to carbon monoxide hazard.
<br /> Fuel-related fire hazard l • Provide for ventilation and/or air monitoring where hazardous accumulation of exhaust emissions is possible.
<br /> Injury from mechanical or lifting • Use hearing protection in close proximity to operating generator,as needed.
<br /> hazard I • Use power cords/extension cords specified by instructions.
<br /> Burns from hot surfaces • Use ground-fault circuit interrupters(GFCls)in accordance with manufacturer's instructions;see D.10.
<br /> "Electrical Work Tasks."
<br /> • Shut down equipment before refueling;see safe practices for flammable/combustible liquids in D.14.

<br /> PNEUMATIC/HYDRAULIC HAZARDS El Never direct outlet nozzle toward body;use guards,restraints,engineering controls as appropriate.
<br /> ❑Air compressor ❑Never use compressed air for cleaning clothes you are wearing.
<br /> ❑Compressed air system ❑If compressed air is used for cleaning,restrict pressure to 30 psi or below,equip nozzle with chip guard.
<br /> ❑High-pressure liquid l ❑Use PPE for eye(goggles or face shield)/hand/head/hearing/skin protection,as appropriate for the hazard.
<br /> El Pressurized steam I ElEnsure tank,hoses,fittings are in good repair using factory fittings,equipped with whip-checks.
<br /> (For compressed gas cylinders,see ❑If pressure relief device poses a hazard to workers,reconfigure or shield device or restrict access by workers.
<br /> D.14."Commercial Chemical
<br /> Products")
<br /> PORTABLE HEATER ❑Follow general safety practices for Operation of Equipment/Machinery(above),and as follows:
<br /> ❑electric l • Keep heater dry and locate heater on level surface away from high traffic areas to prevent tipping.
<br /> ❑fuel powered l • Never use fuel-powered heaters indoors,or near air intake vents,due to carbon monoxide hazard.
<br /> Hazards: I • Provide ventilation and/or air monitoring where hazardous accumulation of exhaust emissions is possible.
<br /> Shock(electrical) l • Keep combustible materials at least 3 feet from hot surfaces.
<br /> Carbon monoxide emissions and • Do not use an extension cord or power strip to power an electric heater.
<br /> fuel-related fire hazards(fueled) • For electric heaters,see D.10.,"Electrical Work Tasks."
<br /> Fires/burns from hot surfaces. I • Shut down fuel-powered equipment before refueling;see safe practices for flammable/combustible liquids
<br /> and/or compressed gases in D.14."Commercial Chemical Products."
