Information on servicing
Prior to beginning work on systems containing FLAMMABLE REFRIGERANTS,
safety checks are necessary to ensure that the risk of ignition is minimised.
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.
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, i.e. non-sparking, adequately sealed or
intrinsically safe.
If any hot work is to be conducted on the refrigeration equipment or any associated
parts, appropriate fire extinguishing equipment shall be available to hand. Have a
dry powder or CO
2 fire extinguisher adjacent to the charging area.
All possible ignition sources, including cigarette smoking, should be kept
sufficiently far away from the site of installation, repairing, removing and disposal,
during which 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.
Ensure that the area is in the open or that it is adequately ventilated before
breaking into the system or conducting any hot work. A degree of ventilation shall
continue during the period that the work is carried out. The ventilation should
safely disperse any released refrigerant and preferably expel it externally into the
atmosphere
