A work station-specific emission value cannot be specified because this value de-
pends on the process and the environmental conditions. It depends on differing
parameters, such as the power range, the component geometry, the material, the
resonance properties of the workpiece, the work station environment, and many
other factors.
Danger from
Toxic Gases and
Vapors The fumes produced during plasma surface treatment contain toxic gases and
vapors.
The fumes produced contain substances that may cause birth defects and can-
cer in some circumstances.
Use at-source extraction source and a room extraction system.
If possible, use integrated extraction devices.
The operator of the plasma system is obliged to maintain the values for the max-
imum allowable concentrations (MAC).
- Ensure that there is sufficient fresh air!
- Arrange the extraction capacity so that at least 3 times the gas used can be
extracted per plasma torch.
Keep your head out of the fumes and gases.
Take the following precautionary measures for fumes and harmful gases:
- Do not breathe them in
- Extract them from the work area using appropriate equipment.
Use breathing apparatus with air supply if there is insufficient ventilation.
When no work is taking place, close the valve of the gas cylinder or the main gas
supply.
If there is uncertainty as to whether the extraction capacity is sufficient, com-
pare the measured toxic emission values against the permissible limit values.
The following components are factors that determine how toxic the fumes are:
- The materials used for the workpiece
- Electrodes
- Coatings
- Cleaning agents, degreasers, and the like
- The type and amount of component contamination
Consult the corresponding material safety data sheets and manufacturer's in-
structions for the components listed above.
Keep flammable vapors (such as solvent vapors) out of the arc radiation range.
Danger from Fire Flying sparks can cause fires and explosions.
Never perform the plasma surface treatment near flammable materials.
Flammable materials must be kept at least 11 meters (36 ft. 1.07 in.) from the
arc or protected with a certified cover.
Keep suitable, tested fire extinguishers on hand.
Sparks and pieces of hot metal may also get into surrounding areas through
small cracks and openings. Take appropriate measures to ensure that there is no
risk of injury or fire.
