24 CDM 3201 Order No. BA 92-12-3321A Issue 19.09.08
THREAT TO LIFE by toxic vapors and airborne particles
Toxic vapors and airborne particles may occur during stud welding
operations, especially with surface treated materials.
Ensure that a fume extraction is available that the room is adequately
ventilated according to accident prevention regulations.
If possible, do not weld in rooms which are lower than 3 meters.
Special regulations apply for confined rooms according to accident
prevention regulations of the official bodies of your country (see
appendix).
THREAT TO LIFE by red-hot metal spatters (fire risk)
Make sure that a fire extinguisher is within reach.
Do not wear clothes, which are contaminated with combustible
materials like oil, grease, kerosene etc. during welding.
Always wear your personal protective equipment such as:
– protective gloves to current standards (see appendix),
– safety goggles with a window providing protection class 2 to
current standards (see appendix),
– non-combustible clothes
– ear protection to current standards (see appendix),
– a protective apron over your clothes,
– a protective headgear when welding overhead.
Before starting to weld, remove all combustible articles and liquids in
vicinity of the workplace.
Weld only in sufficient distance from combustible articles or liquids.
choose a safety distance where there is no risk to injury from welding
spatters!
THREAT TO LIFE by blow-up of explosive gases and materials
Never weld in rooms exposed to danger by explosion.
Special know-how is required when welding hollow parts which
– are combustible or support combustion,
– can emit toxic gases, vapors, or airborne particles,
– can explode.
Never execute such operations, if you do not have such special know-
how.
Observe the regulations for accident prevention and standards
which apply to the use of your stud welding unit (see appendix).
The official Professional Association of your country will
provide you with further information.
Please note that in your country additional standards and safety
conditions (especially rules for accident prevention) may differ
from the standards mentioned in this operating manual.
