Safety Precautions
General Practices
1. ALWAYS WEAR GOGGLES OR SAFETY GLASSES. Refrigerant liquid and battery acid can
permanently damage the eyes (see First Aid under Refrigerant Oil).
2. Never close the compressor discharge valve with the unit in operation. Never operate the unit with the
discharge valve closed.
3. Keep your hands, clothing and tools clear of the fans when the refrigeration unit is running. If it is
necessary to run the refrigeration unit with covers removed, be very careful with tools or meters being
used in the area.
4. Be sure the gauge manifold hoses are in good condition. Never let them come in contact with a fan
motor blade or any hot surface.
5. Never apply heat to a sealed refrigeration system or container.
6. Fluorocarbon refrigerants, in the presence of an open flame or electrical arc, produce toxic gases that
are severe respiratory irritants capable of causing death.
7. Be sure all mounting bolts are tight and are the correct length for their particular application.
8. Use extreme caution when drilling holes in the unit. The holes may weaken structural components.
Holes drilled into electrical wiring can cause fire or explosion. Holes drilled into the refrigeration
system may release refrigerant.
9. Use caution when working around exposed coil fins. The fins can cause painful lacerations.
10. Use caution when working with a refrigerant or refrigeration system in any closed or confined area
with a limited air supply (for example, a trailer, container or in the hold of a ship). Refrigerant tends to
displace air and can cause oxygen depletion, resulting in suffocation and possible death.
11. Use caution and follow the manufacturer’s suggested practices when using ladders or scaffolds.
Refrigerant
When removing any refrigerant from a unit, use a recovery process that prevents or absolutely minimizes
the refrigerant that can escape to the atmosphere. Although fluorocarbon refrigerants are classified as safe
refrigerants when proper tools and procedures are used, certain precautions must be observed when
handling them or servicing a unit in which they are used. When exposed to the atmosphere in the liquid
state, fluorocarbon refrigerants evaporate rapidly, freezing anything they contact.
First Aid
In the event of frost bite, the objectives of First Aid are to protect the frozen area from further injury, to
warm the affected area rapidly, and to maintain respiration.
• EYES: For contact with liquid, immediately flush eyes with large amounts of water and get prompt
medical attention.
• SKIN: Flush area with large amounts of lukewarm water. Do not apply heat. Remove contaminated
clothing and shoes. Wrap burns with dry, sterile, bulky dressing to protect from infection/injury. Get
medical attention. Wash contaminated clothing before reuse.
• INHALATION: Move victim to fresh air and use CPR or mouth-to-mouth ventilation, if necessary.
Stay with victim until arrival of emergency medical personnel.
