Splashes and flying sparks
WARNING ! Splashes and flying sparks constitute a danger of fire and
explosion. Splashes and flying sparks pose a risk of injuries.
Welding generates sparks and -hot spatter. They can ignite combustible ma-
terials and generate explosions. Contact with body parts may entail injuries.
Therefore:
Before you tackle any welding jobs, make sure there are no combustible
and/or explosive materials in the work area.
Do not carry out welding jobs in the vicinity of pressure vessels, tanks, oil
barrels, paint cans and/or in a work area with an explosive atmosphere.
Have fire extinguishing gear ready at hand.
Make sure access and escape routes are not blocked.
During any and all welding jobs: be sure to be wearing a face screen,
non-inflammable safety clothing and welder's gloves.
Do not carry easily inflammable objects in your pockets (matches,
lighters etc.).
Hot surfaces
CAUTION ! Hot surfaces pose a risk of burns.
Electrodes may heat up to 80 degrees centigrade approx. Stock may have
up to 100 degrees right after welding. So there is an acute risk of burning
yourself. Therefore:
Never work without proper safety clothes and gloves near hot compo-
nents.
Let freshly welded parts cool down to ambient temperature before you
go on to work with them.
Vapours
WARNING ! Vapours may constitute a danger to your health.
Stock that has not been properly ground and cleaned before welding may
be contaminated with residues of glues, paints, undercoating products etc.
that may generate harmful or even toxic vapours during welding. Therefore:
Before you tackle any welding jobs, make sure the sheets you want to
weld have been properly ground and cleaned and are free of residues.
Be sure to be wearing a face screen. Respiratory equipment may be rec-
ommendable in case of doubt.
