F2. Ignition sources
Ensure that all the obvious and unobvious ignition sources have been removed from the
equipment and handling areas. Ignition sources can vary greatly and these sources may
include sparks from electrical equipment or welding and cutting tools, hot surfaces, open
flames from heating equipment, smoking materials, etc.
F3. Ventilation
There should be adequate airflow where flammable substances are stored and used.
Good ventilation will mean that any vapor arising from a leak or a release will be rapidly
dispersed. In case one of the components of the refrigerating hermetic circuit (compressor,
dryer, condenser, evaporator, capillary, refrigerant) needs to be serviced, the basic safe
guideline must be always followed:
NEVER USE FLAMES OR HEAT SOURCES IF
FLAMMABLE REFRIGERANT IS PRESENT
INSIDE THE REFRIGERATING CIRCUIT
Flames can be used only when there is evidence that no flammable substance is still inside the
circuit or the circuits; IN CASE OF MULTIPLE CIRCUITS NONE OF THEM MUST CONTAIN
FLAMMABLE SUBSTANCES in case heat sources are to be used: all circuits need to be emptied
and absence of flammable substances must be proved.
IMPORTANT
Provisions for all jobs involving the opening of the refrigerating circuit:
‐
SHUT DOWN THE POWER SUPPLY
‐
MANDATORILY WEAR GLOVES AND GLASSES
‐
DO NOT WORK WITH OPEN FLAMES BEFORE THE PIPEWORK HAS BEEN CUT!
‐
REMOVE ALL SPARK SOURCES FROM THE WORK AREA (LIGHTERS, LAMPS,
CIGARETTES).
