1.02 General Safety Information for Victor
CS Regulator
A Fire Prevention
Welding and cutting operations use fire or combustion
as a basic tool. The process is very useful when properly
controlled. However, it can be extremely destructive if not
performed cor rectly in the proper environment.
1. The work area must have a fireproof floor.
2. Work benches or tables used during welding or cut-
ting operations must have fireproof tops.
3. Use heat resistant shields or other approved material to
protect nearby walls or unprotected flooring from sparks
and hot metal.
4. Keep an approved fire extinguisher of the proper
size and type in the work area. Inspect it regularly to
ensure that it is in proper working order. Know how
to use the fire extin guisher.
5. Move combustible materials away from the work site.
If you can not move them, protect them with fireproof
covers.
!
WARNING
NEVER perform welding, heating, or cutting op-
erations on a container that has held toxic, com-
bustible or flammable liq uids, or vapors. NEVER
perform welding, heating, or cutting operations in
an area containing combustible vapors, flam mable
liquids, or explosive dust.
B Housekeeping
!
WARNING
NEVER
allow oxygen to contact grease, oil, or other
flam mable substances. Although oxygen by itself
will not burn, these substances become highly
explosive. They can ignite and burn violently in
the presence of oxygen.
Keep ALL apparatus clean and free of grease, oil and other
flammable substances.
C Ventilation
!
WARNING
Ade quately ventilate welding, heating, and cutting
work areas to prevent accumulation of explosive
or toxic concen trations of gases. Certain combina-
tions of metals, coatings, and gases generate toxic
fumes. Use respiratory protection equipment in
these circumstances. When welding/brazing, read
and understand the Material Safety Data Sheet for
the welding/brazing alloy.
D Personal Protection
Gas flames produce infrared radiation which may have a
harm ful effect on the skin and especially on the eyes. Select
goggles or a mask with tempered lenses, shaded 4 or darker,
to protect your eyes from injury and provide good visibility
of the work.
Always wear protective gloves and flame-resistant clothing to
protect skin and clothing from sparks and slag. Keep collars,
sleeves, and pockets buttoned. DO NOT roll up sleeves or cuff
pants.
When working in a non-welding or cutting environment,
always wear suitable eye protection or face shield.
!
WARNING
Practice the following safety and operation precau-
tions EVERY TIME you use pressure regulation
equipment. Deviation from the following safety
and operation instructions can result in fire, ex-
plosion, damage to equipment, or injury to the
operator.
E Compressed Gas Cylinders
The Department of Transportation (DOT) approves the design
and manufacture of cylinders that contain gases used for
welding or cutting operations.
1. Place the cylinder (Figure 1-1) where you will use it.
Keep the cylinder in a vertical position. Secure it to a cart,
wall, work bench, post, etc.
