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 I ❑If compressed air is used for cleaning,restrict pressure to 30 psi or below,equip nozzle with chip guard.
<br /> ❑High-pressure liquid I ❑Use PPE for eye(goggles or face shield)/hand/head/hearing/skin protection,as appropriate for the hazard.
<br /> El Pressurized steam I ❑Ensure 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 I • Keep heater dry and locate heater on level surface away from high traffic areas to prevent tipping.
<br /> ❑fuel-powered I • Never use fuel-powered heaters indoors,or near air intake vents,due to carbon monoxide hazard.
<br /> Hazards: • Provide ventilation and/or air monitoring where hazardous accumulation of exhaust emissions is possible.
<br /> Shock(electrical) • Keep combustible materials at least 3 feet from hot surfaces.
<br /> Carbon monoxide emissions and • Plug electric heaters directly into wall outlet(don't use extension cord or power strip).
<br /> fuel-related fire hazards(fueled) • For electric heaters,see D.10.,"Electrical Work Tasks."
<br /> Fires/burns from hot surfaces. • 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."
<br /> LOCKOUT/TAGOUT(LO/TO)OF ❑Prepare site-specific written LC/TO program,and equipment-specific written LC/TO procedures(as
<br /> HAZARDOUS ENERGY To prevent applicable);implement control procedures for hazardous energy sources,provide locks/tags,train workers,
<br /> unplanned equipment start-up or designate"authorized"personnel,notify"affected"personnel.
