English
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:
• 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.
Instant-on torches
Plasma arc comes on immediately when the torch switch is activated.
The plasma arc will cut quickly through gloves and skin.
• Keep away from the torch tip.

• Do not hold metal near the cutting path.
• Never point the torch toward yourself or others.
