SECTION IV: REFRIGERATION HAZARDS
GENERAL
Refrigeration systems involve both electrical power and mechanical action. These
systems may present any of t
he potential dangers shown in the sections on electrical and
mechanical hazards contained in this manual. See Sections II and III for further
information.
A. Compressed Refrigerant
Refrigeration systems involve the compression and evaporation of gases. The
pressures contained represent a potential hazard if suddenly released in confined
areas. Caution is required when performing maintenance tests or repairs. All
testing of sealed refrigeration systems must be done by trained personnel who are
familiar with the systems and pressures involved.
B. Physical Protection
The accidental release of refrigerant gases can result in physical injuries. Always
wear protective glasses and protect your hands, face, and body when working near
the refrigeration system.
WARNING:
ALWAYS WEAR EYE PROTECTION AND PROTECT YOUR HANDS,
FACE, AND BODY WHEN WORKING NEAR THE REFRIGERATION
SYSTEM.
SECTION V: TEMPERATURE HAZARDS
GENERAL
Maintenance personnel should be alerted to the potential hazards from hot metal surfaces.
High temperatures may be present throughout the refrigeration system even though
electrical power has been removed.
