R290.
2.2.1. GENERAL INSTRUCTIONS
1. INFORMATION ON SERVICING
1.1 Checks to the area
Prior to beginning work on systems containing ammable refrigerants, safety checks are
necessary to ensure that the risk of ignition is minimised. For repair to the refrigerating system,
the following precautions shall be complied with prior to conducting work on the system.
1.2 Work procedure
Work shall be undertaken under a controlled procedure so as to minimise the risk of a ammable
gas or vapour being present while the work is being performed.
1.3 General work area
All maintenance sta and others working in the local area shall be instructed on the nature of
work being carried out. Work in conned spaces shall be avoided. The area around the workspace
shall be sectioned o. Ensure that the conditions within the area have been made safe by control
of ammable material.
1.4 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 ammable atmospheres. Ensure that the leak
detection equipment being used is suitable for use with ammable refrigerants, i.e. non-sparking,
adequately sealed or intrinsically safe.
1.5 Presence of re extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated parts,
appropriate re extinguishing equipment shall be available to hand. Have a dry powder or CO₂
re extinguisher adjacent to the charging area.
1.6 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 ammable refrigerant shall use any sources of ignition
in such a manner that it may lead to the risk of re or explosion. All possible ignition sources,
including cigarette smoking, should be kept suciently far away from the site of installation,
repairing, removing and disposal, during which ammable 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 ammable hazards or ignition risks. “No Smoking” signs
