ponents or conditions including, but not limited to:

heavy objects, refrigerants, materials under pressure,

rotating components, and both high and low voltage.

Each of these items has the potential, if misused or

handled improperly, to cause bodily injury or death. It

is the obligation and responsibility of rigging, instal-

lation, and operating/service personnel to identify and

recognize these inherent hazards, protect themselves,

and proceed safely in completing their tasks. Failure

to comply with any of these requirements could result

in serious damage to the equipment and the property in
