Precautions for Work with Flammable
Refrigerant
Prior to beginning work on systems containing FLAMMABLE
REFRIGERANTS, safety checks are necessary to ensure that
the risk of ignition is minimized.
1. Work shall be undertaken under a controlled procedure so
as to minimize the risk of a flammable gas or vapor being
present while the work is being performed.
2. All maintenance staff and others working in the local area
shall be instructed on the nature of work being carried out.
Work in confined spaces shall be avoided.
3. The area shall be checked with an appropriate refrigerant
detector prior to and during work, to ensure the technician
is aware of potentially toxic or flammable atmospheres.
Ensure that the leak detection equipment being used is
suitable for use with all applicable refrigerants.
4. If any hot work is to be conducted on the refrigerating
equipment or any associated parts, appropriate fire
extinguishing equipment shall be available to hand. Have
a dry powder or CO2 fire extinguisher adjacent to the
charging area.
5. No person carrying out work in relation to a refrigeration
system which involves exposing any pipe work shall use
any sources of ignition in such a manner that it may lead
to the risk of fire or explosion. All possible ignition sources,
including cigarette smoking, should be kept sufficiently far
