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.
