Wear for special work
For special work special protective equipment is necessary. It will be indicated in the certain
chapters. Following special equipment will be explained:
Face screen
protects the face and eyes against splashes, flying sparks and other hot
particles.
Ear protection
protects against hearing damage.
Welder's gloves
protect the hands against splashes, flying sparks and other hot particles,
and prevent contact with hot surfaces. Never use wet welder's gloves.
2.3 Particular dangers
Electricity
DANGER ! Electricity constitutes a danger to life and limb.
Touching live components can result in a fatal electrical shock. Therefore:
As soon as you notice any damage to insulation, disconnect the power
supply and have the damage repaired.
Before any and all electrical works: disconnect power, earth and short.
Check whether equipment is really dead.
Keep live components away from liquids and humidity. They may cause
short circuits.
Protect cables against running over, contact with oils, aggressive sub-
stances, tools, pointed and/or hot objects.
When pulling from a socket: Never pull on the cable. Pull on the plug.
Do not use the cable to trail or drag equipment over the floor. Always
grab equipment by the handles provided for that purpose.
Use strain relief clamps to protect cables.
Make sure protective ground conductors have been connected
properly.
Electromagnetic fields
DANGER! Electromagnetic fields pose a potentially fatal hazard to
people with pacemakers or other magnetisable implants.
Electromagnetic fields affect the functionality of pacemakers and other mag-
netisable implants. Electromagnetic fields can irritate human sense organs,
nerve and muscle cells. Therefore:
Persons with pacemakers or other magnetisable implants must not ap-
proach the work area.
Be sure to put up suitable warning signs.
Be sure to put warning signs on access ways and doors leading to the
work area.
Do not guide welding cables along people's heads or spines. (To comply
safely with permissible exposure limits, keep distances ≥ 20 cm. Keep a
distance of at least 1 cm between cable assemblies and people's heads /
spines.)
Electromagnetic fields – hazard to magnetisable objects
Magnetisable data carriers and similar objects that may suffer from mag-
netism must not be brought close to this equipment.
