Safety precautions

2-3. 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 ﬂ ammable atmospheres.

•

Ensure that the leak detection

equipment being used is suitable

for use with ﬂ ammable refrigerants,

i.e. non sparking, adequately

sealed or intrinsically safe.

•

In case of leakage/spillage

happened, immediately ventilate

area and stay upwind and away

from spill/release.

•

In case of leakage/spillage

happened, do notify persons down

wind of the leaking/spill, isolate

immediate hazard area and keep

unauthorized personnel out.

2-4. Presence of ﬁ re extinguisher

•

If any hot work is to be conducted

on the refrigeration equipment or

any associated parts, appropriate

ﬁ re extinguishing equipment shall

be available at hand.

•

Have a dry powder or CO

2

ﬁ re

extinguisher adjacent to the

charging area.

2-5. 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

ﬂ ammable refrigerant shall use

any sources of ignition in such a

manner that it may lead to the risk

of ﬁ re or explosion. He/She must

not be smoking when carrying out

such work.

•

All possible ignition sources,

including cigarette smoking, should

be kept sufﬁ ciently far away from

the site of installation, repairing,

removing and disposal, during

which ﬂ 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 ﬂ ammable hazards or

ignition risks.

•

“No Smoking” signs shall be

displayed.

2-6. 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.
