GENERAL INSTRUCTIONS

Checks to the area
Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the
risk of ignition is minimized. For repair to the refrigerating system, the following precautions shall be complied with prior
to con-ducting work on the system.
Work procedure
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.
General work area
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. The area around the workspace shall be sectioned off. Ensure that the
conditions within the area have been made safe by control of flammable material.
Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is
aware of potentially flammable atmospheres. Ensure that the leak section equipment being used is suitable for use with
flammable refrigerants, i.e. nonsparking, adequately sealed or intrinsically safe.
Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated parts, propriate fire extinguishing
equipment shall be available to hand. Have a dry powder or CO 2 fire extinguisher adjacent to the charging area.
No ignition sources
No person carrying out work in relation to a refrigeration system which involves exposing any pipe work that contains or
has contained flammable refrigerant 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 away from the site
of installation, repairing, removing and disposal, during which flammable refrigerant can possibly be released to the
surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make sure that there
are no flammable hazards or ignition risks. "No Smoking" signs shall be displayed.
