F6-BOOST FLAMMABLE REFRIGERANT
SAFETY INSTRUCTIONS
The following are additional safety recommendations when servicing HVAC&R equipment containing
flammable refrigerants. These instructions do not replace existing occupational hazardous procedures or
other local, state and/or federal agency regulations.
Technicians working on HVAC&R systems with flammable refrigerants should have detailed knowledge and
skills in handling flammable refrigerants, personal protective equipment, refrigerant leak prevention, handling
of cylinders, leak detection and monitoring, and proper disposal of contaminated refrigerants. Additional
knowledge of legislation, regulations, and standards relating to flammable refrigerants may also be required.
Check your local occupational safety codes.
The area of service should be marked as Temporary Hazardous or Flammable Zone. This will be a 3 meter
(10 feet) perimeter around the HVAC&R equipment being serviced. No smoking signs or other hazardous
zone signs should be posted. Local supervisor should be notified of the hazardous zone's existence.
The following are recommended practices when servicing flammable HVAC&R equipment:
• A flammable gas detector should be used to monitor the air in the Temporary Flammable Zone.
• A dry powder or CO2 fire extinguisher must be available at the service location.
• An ignition proof ventilation fan should be used to provide a minimum of 5 air changeovers per hour.
• Ensure the HVAC&R equipment has been disconnected from electrical service.
• All potential ignition sources within the Temporary Flammable Zone must be disabled.
• When connecting service equipment such as vacuum pumps, scales, recovery units, etc. to a power
source, the connection must be made outside the Temporary Hazardous Zone perimeter.
• A grounding strap must be used between the recovery unit's metal INLET or OUTLET port and recovery
tank's unpainted metal fitting. The grounding strap is used to dissipate any static electricity build up that
can occur, especially during liquid recovery.
• Once the recovery process of the flammable refrigerant is complete, the HVAC&R system should be purged
with 100% Nitrogen. Do not use air.
DANGER - EXPLOSION RISK: Do not mix flammable refrigerants with air. All precautions
must be taken to eliminate the mixing of air with flammable refrigerants, including
monitoring the recovery cylinder of air or oxygen content.
