FIRE HAZARDS
1. Prevent sparks or hot scale from producing flames.
2. Remove inflammable or combustible materials from the cutting area.
3. Make sure that fire-fighting equipment is located near the work area.
4. Situate the unit in an area where the air can be sucked in and exhausted
from the grilles on the panel.
ELECTRO-MAGNETIC INTERFERENCE (EMI)
1. Make sure that there are no other power supply cables, control lines,
telephone leads or other equipment near the unit.
2. Make sure that there are no radio receivers or televisions.
3. Make sure there are no computers or other control systems.
4. Make sure that there is no-one with a pacemaker or hearing aid in the
area around the unit.
5. Check the immunity of any other equipment operating in the same
environment. In certain cases additional protective measures may be
required. Before installing the plasma cutting unit, carry out an inspection
of the surrounding area, observing the following guidelines:
Interference can be reduced in the following ways:
1. If there is interference in the power supply line, an E.M.I. filter should be
inserted between the mains and the unit.
2. The output cables of the unit should be shortened; these should be kept
close together and stretched along the ground.
PERSONAL PROTECTIVE EQUIPMENT(PPE)
One of the hazards during the cutting process is the emission of
electromagnetic waves due to the electric arc. The length of these waves
ranges from infrared to ultraviolet. If these rays hit the eyes they can cause
various complaints such as conjunctivitis, burns to the retina, deterioration of
sight, etc. Moreover a high concentration of ultraviolet rays can burn the skin.
It is, therefore, extremely important that the operator uses adequate safety
equipment and clothing, such as:
CAUTION: DO NOT CUT FUEL OR LUBRICANT CONTAINERS EVEN IF THEY
ARE EMPTY. DO NOT CUT CONTAINERS OR CASINGS WHICH CONTAIN
FLAMMABLE MATERIAL. NEVER CUT IN ENVIRONMENTS WHICH ARE
POLLUTED BY FLAMMABLE GAS OR COMBUSTIBLE LIQUID VAPOURS
(SUCH AS PETROL).
