Nitrogen Dioxide
Nitrogen dioxide gas is produced when nitrogen and oxygen in the air pass through
the electric arc. A hazard may exist if uncontrolled, excessive levels of nitrogen
dioxide are formed. With proper venting to the outside, the machine's internal
ventilation system is adequate to control nitrogen dioxide during torch cutting, if the
system is functioning normally.
Acetyl Chloride
Acetyl chloride gases form in the air surrounding the plasma arc when the airborne
vapors of chlorinated solvents or degreasers decompose upon being exposed to the
ultraviolet radiation of the arc. A hazard may exist if uncontrolled, excessive levels
of acetyl chlorides are formed. A pungent "sweetish" aroma similar to chlorine
bleach is the first sign that these gases are being produced. Shut down the plasma
arc cutting system immediately if you detect the acetyl chloride odor. Do not resume
cutting until you locate and control the source of the vapors.
Various cleaning solvents and vapor degreasers contain chemicals that decompose
rapidly when exposed to ultraviolet radiation.
If the solvents, cleaning solutions, or vapor degreasers used in the shop contain any
of the following chemicals,
do not use them near the plasma arc cutting system:
1. trichloroethylene
2. trichloroethane
3. perchloroethylene
4. perchloroethane
5. trifluoro-trichloroethane (fluorocarbon-113)
These chemicals also decompose into small amounts of the toxic gases phosgene
and chlorine. You will notice the acetyl chloride odor long before phosgene or
chlorine levels become harmful.
The vapors can decompose up to several feet away from the arc,
do not rely on the
machine's internal ventilation system to control solvent vapors and their products
.
Do not use or store chlorinated solvents, cleaning solutions, and vapor degreasers
close to the machine, where the vapors can enter the torch-cutting area.
NOTE:
It may prove advisable to provide separate ventilation for the
solvent/degreaser storage area.
