Safety precautions

1. Servicing

1) Checks to the area

Prior to beginning work on systems containing

flammable 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.

2) Work procedure

Work shall be undertaken under a controlled

procedure so as to minimise the risk of a

flammable gas or vapour being present while

the work is being performed.

3) General work area

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.

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

flammable atmospheres. Ensure that the leak

detection equipment being used is suitable

for use with flammable refrigerants, i.e. non-

sparking, adequately sealed or intrinsically

safe.

5) Presence of fire extinguisher

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 CO2 fire extinguisher adjacent

to the charging area.

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

flammable refrigerant shall use any sources

of ignition in such a manner that it may lead

to the risk of fire or explosion. All possible

ignition sources, including cigarette smoking,

should be kept sufficiently far away from the

site of installation, repairing, removing and

disposal, during which flammable 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.

7) 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.

8) 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

Warning

WARNING

Any person who is involved with working on or breaking into a refrigerant circuit should

hold a current valid certificate from an industry-accredited assessment authority, which

authorises their competence to handle refrigerants safely in accordance with an industry

recognised assessment specification.

Servicing shall only be performed as recommended by the equipment manufacturer.

Maintenance and repair requiring the assistance of other skilled personnel shall be carried

out under the supervision of the person competent in the use of flammable refrigerants.
