Toxic Fumes - laguna Plasma Level 2 CNC Owner's Manual

TOXIC FUMES-

Proper precautions must be exercised to prevent the exposure of others in the vicinity to toxic
fumes that may be generated while plasma cutting.
Certain chlorinated solvents such a perchloroethylene and trichlorethylene will decompose under
ultraviolet radiation to form phosgene and other gasses. Care must be taken to avoid the use of
these solvents on materials being cut with plasma arc cutting equipment. Containers of these
solvents and other degreasing agents should be removed from the immediate area around the
plasma arc.
Metals coated with or containing significant amounts of lead, cadmium, zinc, mercury, or
beryllium can produce harmful concentrations of toxic fumes when the plasma arc cuts. Adequate
local exhaust ventilation must be used, or the operator must be supplied with special equipment
to guarantee a supply of fresh air such as a respirator or air supplied helmet.
Metals coated with materials that emit toxic fumes must not be cut unless:
1.) The coating is removed prior to cutting.
2.) The area is adequately ventilated.
3.) The operator is supplied with fresh air breathing equipment.
