Must ensure no leak during refrigerant charge.
Must ensure conducting safety checks before starting work on systems that
contain flammable refrigerants to minimize the risk of ignition.
Must ensure to follow all related safety precautions before conducting work on
the system when repairing the refrigeration system.
Must ensure the work is conducted under controlled procedures to minimize the
risk of a flammable gas or vapor being present.
Avoid working in enclosed space and ensure a safety distance of at least 2
meters from any source, or establish a free space zone of at least 2 meters in
radius.
Must use suitable protective equipment per the actual situation.
Must ensure to stay away from any flammable materials and heat-producing
items.
A suitable refrigerant detector should be used to check the area before and
during work to identify potentially combustible environments.
The leak detection equipment should be non-sparking, adequately sealed, or
intrinsically safe.
If a leak or spill occurs, ventilate the area immediately, stay upwind and avoid
the spill/release.
In the event of a leak or spill, inform individuals downwind of the leak/spill,
isolate the immediate hazard area, and restrict unauthorized personnel.
If any heat-related work is to be done on the cooling equipment or any related
parts, relevant fire extinguishing equipment should be accessible.
Keep a dry powder or CO
When working on a system, avoid using any ignition sources that could
risk a fire or explosion.
Keep all potential ignition sources, including smoking, sufficiently far from the
installation, repair, removal, and disposal site where flammable refrigerant could
be released.
Check the area around the equipment before starting work to ensure that
thereare no flammable hazards or ignition risks (electrical sockets included).
Must display "No Smoking" signs.
Must ensure the area is open or adequately ventilated before opening the
system or conducting any heat-related work.
