Safety
SR-45i User’s Manual
Section 1 Safety
General Precautions
Whereas plasma cutting has been used safely for years, it does require certain
precautions to ensure the safety of the operator and other people around the
equipment. It is management’s responsibility to see that the following safety
information is provided to each person who will operate, observe, perform
maintenance, or work in close proximity to this piece of equipment.
Installation, as well as repairs, made to the SR-45i system should only be
performed by qualified personnel. The SR-45i system makes use of both A.C.
and D.C. circuitry for operation.
Fatal shock hazard does exist. Exercise
extreme caution while working on the system
.
Ultraviolet Radiation Protection
Plasma cutting produces ultraviolet radiation similar to a welding arc. This
ultraviolet radiation can cause skin and eye burns. For this reason, it is essential
that proper protection be worn. The eyes are best protected by using safety
glasses or a welding helmet with an AWS No. 8 shade or ISO 4850 No. 11 shade,
which provides protection up to 100 amperes. All exposed skin areas should be
covered with flame-retardant clothing. The cutting area should also be prepared
in such a way that ultraviolet light does not reflect. Walls and other surfaces
should be painted with dark colors to reduce reflected light. Protective screens or
curtains should be installed to protect additional workers in the area from
ultraviolet radiation.
Noise Protection
The SR-45i system generates high noise levels while cutting. Depending on the
size of the cutting area, distance from the cutting torch, and arc current cutting
level, acceptable noise levels may be exceeded. Proper ear protection should be
used as defined by local or national codes. See Section 2 for noise emission
levels.
Toxic Fume Prevention
Care should be taken to ensure adequate ventilation in the cutting area. Some
materials give off toxic fumes that can be harmful or fatal to people in the vicinity
of the cutting area. Also, some solvents decompose and form harmful gases when
exposed to ultraviolet radiation. These solvents should be removed from the area
prior to cutting.
