<br /> WELDING,CUTTING,HOT WORK ❑General safe work practices for operators of welding equipment:
<br /> ❑Arc-welding(electrical arc) • Hot work permit system shall be implemented.
<br /> ❑Gas-welding/cutting(fuel gases) • Operator properly protected(eye protection,clothing,apron,etc.).
<br /> Hazards: • Fire hazard controls(watcher,fire extinguisher,water,remove combustibles from work area).
<br /> UV/IR)ight-eye/skin burns ' • 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(physical see D.14."Commercial Chemical Products."
<br /> j hazards,fire,oxygen deficiency) I ❑For arc welding,follow electrical safe work practices;see D.10."Electrical Work Tasks."
<br /> electrical shock
<br /> ❑For inhalation hazards from welding fumes(toxic metals)and gases(asphyxiant,flammable),see D.14.
<br /> "Commercial Chemical Products."
<br /> ® PORTABLE ELECTRIC GENERATOR j ®Follow general safe work practices for Powered Tools&Equipment(above),and as follows:
<br /> Hazards: • Use in accordance with manufacturer's instructions,including instructions for grounding the generator.
<br /> Electrical shock I • Keep generator and work area dry.
<br /> Carbon monoxide inhalation • Never use indoors,or near building air intake vents due to carbon monoxide hazard.
<br /> hazard • Provide for ventilation and/or air monitoring where hazardous accumulation of exhaust emissions is possible.
<br /> Fuel-related fire hazard ! • Use hearing protection in close proximity to operating generator(where noise level exceeds 85 dBA).
<br /> Injury from mechanical or lifting i • Use power cords/extension cords specified by instructions.
<br /> hazard • Use ground-fault circuit interrupters(GFCIs)in accordance with manufacturer's instructions;see D.10.
<br /> Burns from hot surfaces "Electrical Work Tasks."
<br /> • Shut down equipment before refueling;see safe practices for flammable/combustible liquids in D.14.
<br /> "Commercial Chemical Products."
<br /> PNEUMATIC/HYDRAULIC HAZARDS ❑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 ❑Use PPE for eye(goggles or face shield)/hand/head/hearing/skin protection,as appropriate for the hazard.
<br /> I
<br /> ❑Ensure tank,hoses,fittings are in good repair using factory fittings,equipped with whip-checks.
<br /> ❑Pressurized steam
<br /> (For compressed gas cylinders,see ' ❑If pressure relief device poses a hazard to workers,reconfigure or shield device or restrict access by workers.
