Examples for such working procedures are:
- breaking into the refrigerating circuit.
- opening of sealed components.
- opening of ventilated enclosures.
● Information on servicing
- Prior to beginning work on systems, safety checks are
necessary to ensure that the risk of ignition is
minimized.
- Work shall be undertaken under a controlled procedure
so as to minimized the risk of flammable gas or vapor
being present while the work is being performed.
- 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. The leak
detection equipment should be suitable for use with all
applicable refrigerants, i.e. non-sparking, adequately
sealed or intrinsically safe.
● Presence of fire extinguisher
- If any hot work is to be conducted, appropriate fire
extinguishing equipment shall be available to hand.
Have a dry powder or CO2 fire extinguisher adjacent to
the charging area.
● No ignition sources
- All possible ignition sources, including cigarette
smoking, should be kept sufficiently far away from the
site of installation, repairing, removing and disposal.
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.
● Ventilated area
- 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.
● Checks to the refrigeration equipment
- where electrical components are being changed,
they shall be fit for the purpose and to the correct
specification.
At all times the manufacturer's maintenance and service
guidelines shall be followed. If in doubt, consult the
manufacturer's technical department for assistance.
The following checks shall be applied to installations.
- The charge size is in accordance with the room size
within which the refrigerant containing parts are installed.
