§1 SAFETY
Important Safety Precautions
OPERATION AND MAINTENANCE OF PLASMA ARC EQUIPMENT CAN BE DANGEROUS TO YOUR
HEALTH.
Plasma arc cutting produces intense electric and magnetic emissions that may interfere with the
proper function of cardiac pacemakers, hearing aids, or other electronic health equipment. Persons
who work near plasma arc cutting applications should consult their medical health qualified
technician and the manufacturer of the health equipment to deter- mine whether a hazard exists.
To prevent possible injury, read, understand and follow all warnings, safety precautions and
instructions before using the equipment.
GASES AND FUMES
Gases and fumes produced during the plasma cutting process can be dangerous and hazardous to your
health.
Keep all fumes and gases from the breathing area. Keep your head out of the cutting fume plume.
Use an air-supplied respirator if ventilation is not adequate to remove all fumes and gases.
The kinds of fumes and gases from the plasma arc depend on the kind of metal being used, coatings
on the metal, and the different processes. You must be very careful when cutting or cutting any
metals which may contain one or more of the following:
Antimony
Chromium
Mercury
Beryllium
Arsenic
Cobalt
Nickel
Lead
Barium
Copper
Selenium
Silver
Cadmium
Manganese Vanadium
Always read the Material Safety Data Sheets (MSDS) that should be supplied with the material you are
using.
These MSDSs will give you the information regarding the kind and amount of fumes and gases that may
be dangerous to your health.
Use special equipment, such as water or down draft cutting tables, to capture fumes and gases.
Do not use the plasma torch in an area where combustible or explosive gases or materials are
located.
Phosgene, a toxic gas, is generated from the vapors of chlorinated solvents and cleansers. Remove
all sources of these vapors.
