SAFETY INSTRUCTIONS THERMAL ARC 161 S
Manual 0-5183 1-5 Safety Instructions
C Ventilation
!
WARNING
Ade quately ventilate welding, heating, and cutting
work areas to prevent accumulation of explosive or
toxic concen trations of gases. Certain combinations
of metals, coatings, and gases generate toxic fumes.
Use respiratory protection equipment in these circum-
stances. 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 precautions
EVERY TIME you use pressure regulation equipment.
Deviation from the following safety and operation
instructions can result in fire, explosion, 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.
Figure 1-1: Gas Cylinders
!
WARNING
Cylinders are highly pressurized. Handle with care.
Serious accidents can result from improper handling
or mis use of compressed gas cylinders DO NOT drop
the cylinder, knock it over, or expose it to excessive
heat, flames or sparks. DO NOT strike it against other
cylinders. Contact your gas supplier or refer to CGA
P-1 “Safe Handling of Compressed Gases in Contain-
ers” publication.
NOTE
CGA P-1 publication is available by writing the Com-
pressed Gas Association, 4221 Walney Road, 5th
Floor, Chantilly,VA 20151-2923
2. Place the valve protection cap on the cylinder whenever
mov ing it, placing it in storage, or not using it. Never drag
or roll cylinders in any way. Use a suitable hand truck to
move cylin ders.
3. Store empty cylinders away from full cylinders. Mark them
“EMPTY” and close the cylinder valve.
4. NEVER use compressed gas cylinders without a pressure
reducing regulator attached to the cylinder valve.
5. Inspect the cylinder valve for oil, grease, and damaged
parts.
!
WARNING
DO NOT use the cylinder if you find oil, grease or dam-
aged parts. Inform your gas supplier of this condition
immediately.
6. Momentarily open and close (called “cracking”) the cylinder
valve to dislodge any dust or dirt that may be present in the
valve.
CAUTION
Open the cylinder valve slightly. If you open the valve
too much, the cylinder could tip over. When cracking
the cylinder valve, DO NOT stand directly in front of
the cylinder valve. Always perform cracking in a well
ventilated area. If an acetylene cylinder sprays a mist
when cracked, let it stand for 15 minutes. Then, try to
crack the cylinder valve again. If this problem persists,
contact your gas supplier.
