SAFETY
The plasma arc by itself is the heat source
used for cutting. Accordingly, although the
plasma arc has not been identified as a
source of toxic fumes, the material being cut
can be a source of toxic fumes or gases that
deplete oxygen.
Fumes produced vary depending on the
metal that is cut. Metals that may release
toxic fumes include, but are not limited to,
stainless steel, carbon steel, zinc
(galvanized), and copper.
In some cases, the metal may be coated
with a substance that could release toxic
fumes. Toxic coatings include, but are not
limited to, lead (in some paints), cadmium
(in some paints and fillers), and beryllium.
Gases produced by plasma cutting vary
based on the material to be cut and the
method of cutting, but may include ozone,
oxides of nitrogen, hexavalent chromium,
hydrogen, and other substances if such are
contained in or released by the material
being cut.
Caution should be taken to minimize
exposure to fumes produced by any
industrial process. Depending upon the
chemical composition and concentration of
the fumes (as well as other factors, such as
ventilation), there may be a risk of physical
illness, such as birth defects or cancer.
It is the responsibility of the equipment and
site owner to test the air quality in the area
where the equipment is used and to ensure
that the air quality in the workplace meets all
local and national standards and regulations.
The air quality level in any relevant
workplace depends on site-specific variables
such as:
TOXIC FUMES CAN CAUSE INJURY OR DEATH
• Table design (wet, dry, underwater).
• Material composition, surface finish, and
composition of coatings.
• Volume of material removed.
• Duration of cutting or gouging.
• Size, air volume, ventilation and filtration
of the work area.
• Personal protective equipment.
• Number of welding and cutting systems in
operation.
• Other site processes that may produce
fumes.
If the workplace must conform to national or
local regulations, only monitoring or testing
done at the site can determine whether the
site is above or below allowable levels.
To reduce the risk of exposure to fumes:
• Remove all coatings and solvents from the
metal before cutting.
• Use local exhaust ventilation to remove
fumes from the air.
• Do not inhale fumes. Wear an air-supplied
respirator when cutting any metal coated
with, containing, or suspected to contain
toxic elements.
• Assure that those using welding or cutting
equipment, as well as air-supplied
respiration devices, are qualified and
trained in the proper use of such
equipment.
• Never cut containers with potentially toxic
materials inside. Empty and properly clean
the container first.
• Monitor or test the air quality at the site as
needed.
• Consult with a local expert to implement a
site plan to ensure safe air quality.
