Safety precautions when working on air conditioning systems
Risk of fatal injury and explosion from sources of ignition
Risk of fatal injury and explosion from sources of ignition in the
vicinity of air conditioning systems and refrigerant tanks. Escap‐
ing refrigerant could ignite and cause an explosion. Risk of ex‐
plosion leading to loss of life or serious injuries.
– Never bring sources of ignition close to air conditioning sys‐
tems and refrigerant tanks.
– Avoid electrostatic discharge, sparks from tools striking sur‐
faces and hot surfaces.
Risk of damage to refrigerant lines
There is a risk of damage to the refrigerant lines due to rupture of
the inner foil.
– Never bend refrigerant lines to a radius less than 100 mm.
1.2
Safety precautions when handling refrigerants
Risk of suffocation and poisoning from refrigerant
Coughing and nausea leading to suffocation and poisoning from
refrigerant vapours possible.
– Never inhale refrigerant vapours.
– Only work on the refrigerant circuit and refrigerant tanks in well
ventilated areas.
– Never work in or near cellars or other low lying areas.
