SECTION IV: REFRIGERATION HAZARDS
GENERAL
Refrigeration systems involve both electrical power and mechanical action. These
systems may present any of the 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.
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.
ALWAYS WEAR EYE PROTECTION AND PROTECT YOUR
HANDS, FACE, AND BODY WHEN WORKING NEAR
THE REFRIGERATION SYSTEM
