Electricity
DANGER! Electric shock hazard!
Contact with live parts entails an immediate risk of electric shock. Damage
to the insulation or individual parts can create a very great hazard.
Therefore:
−
If damage to the insulation is discovered, switch off the power supply
immediately and have the necessary repairs carried out.
Have work on the electrical system carried out only by qualified electri-
cians.
−
Before all work on the electrical system, disconnect the power, earth
and short.
−
Before maintenance, cleaning and repair work, switch off the power
supply and secure to prevent restarting.
−
Do not bypass or deactivate fuses or circuit breakers. Use only fuses
with the correct amperage for replacement.
Keep moisture away from live parts. This can result in short-circuits.
Electromagnetic fields
DANGER! Risk of death for persons with heart pacemakers or other
magnetically influenced implants!
Electromagnetic fields impair the function of heart pacemakers and other
magnetically influenced implants. Electromagnetic fields can cause irritation
to sensory organs, nerve and muscle cells. Therefore:
– Keep persons with heart pacemakers and other magnetically influenced
implants away from the working area.
– Post signs at the working area accordingly.
– Post signs at the accesses and doors to the working area accordingly.
– Do not run welding cables over your head or along your spine. (The ex-
posure limits are safely observed for distances of
≥
20 cm. Maintain a
minimum distance of 1 cm between the cable package and your head or
spine!).
Electromagnetic fields – Danger for magnetisable property!
Keep magnetisable data media and other magnetically influenced objects
away from the working area.
Weld spatter and flying sparks
WARNING! Fire and explosion hazard from weld spatter and flying
sparks! Risk of injury from weld spatter and flying sparks!
Weld spatter and sparks can occur during welding. These can cause fires
and explosions. These can cause injuries if they contact the body. There-
fore:
– Before starting welding work, ensure that there are no inflammable or
explosive materials in the vicinity of the working area.
– Do not carry out welding work in particular in the vicinity of pressure
vessels, tanks, oil drums, paint and lacquer drums or in areas with a
potentially explosive atmosphere.
– Have fire fighting equipment on hand.
– Keep access and escape routes clear.
– During all welding work, always wear a face mask, fireproof protective
working clothes and welder's gloves.
– Do not carry easily inflammable items such as matches or cigarette
lighters with you.
