Protecting your-
self and others
Danger from toxic
gases and va-
pours
Persons involved with welding exposes themselves to numerous risks, e.g.:
- flying sparks and hot pieces of metal
- light from the arc, which can damage eyes and skin
- hazardous electromagnetic fields, which endanger the lives of people us-
ing cardiac pacemakers
- risk of electrocution from mains current and welding current
- greater noise pollution
- harmful welding smoke and gases
Anyone working on the workpiece while welding is in progress must wear suit-
able protective clothing with the following properties:
- flame-resistant
- insulating and dry
- covers the whole body, is undamaged and in good condition
- Safety helmet
- trousers with no turn-ups
Protective clothing refers to a variety of different items. Operators should:
- protect eyes and face from UV rays, heat and sparks using a protective
visor and regulation filter.
- behind the safety visor, wear regulation protective goggles with side pro-
tection.
- wear stout footwear that provides insulation even in wet conditions
- wear suitable gloves to protect hands (electrically insulated and providing
protection against heat).
- Insulated ear protection should be worn to reduce the harmful effects of
noise and to prevent injury.
Keep all persons, especially children, out of the working area while any devic-
es are in operation or welding is in progress. If, however, there are people in
the vicinity,
- make them aware of all the dangers (risk of dazzling by the arc, injury
from flying sparks, inhaling welding fumes, noise, possible danger from
mains or welding current, etc),
- provide suitable protective equipment or
- erect suitable safety screens/curtains.
The fumes produced during welding contain harmful gases and vapours.
Welding fumes contain substances that may, under certain circumstances,
cause birth defects or cancer.
Keep your face away from welding fumes and gases.
Fumes and hazardous gases
- must not be breathed in
- must be extracted from the working area using appropriate methods.
Ensure an adequate supply of fresh air.
Otherwise, a protective mask with an air supply must be worn.
Close the shielding gas cylinder valve or main gas supply if no welding is tak-
ing place.
If there is any doubt about whether the extraction system is powerful enough,
then the measured toxic emission values should be compared with the permis-
sible limit values.
