SAFETY PRECAUTIONS
These Safety Precautions are for your protection. They summarize precau-
tionary information from the references listed in Additional Safety Informa-
tion section. Before performing any installation or operating procedures,
be sure to read and follow the safety precautions listed below as well as all
other manuals, material safety data sheets, labels, etc. Failure to observe
Safety Precautions can result in injury or death.
PROTECT YOURSELF AND OTHERS - Some welding, cutting and gouging
processes are noisy and require ear protection. Hot metal can
cause skin burns and heat rays may injure eyes. Training in
the proper use of the processes and equipment is essential to
prevent accidents. Also:
1. Always wear safety glasses with side shields in any work area,
even if welding helmets, face shields, or goggles are also required.
2. Wear flameproof gauntlet type gloves, heavy long-sleeve shirt,
cuffless trousers, high-topped shoes, and a welding helmet or cap
for hair protection, to protect against hot sparks and hot metal. A flameproof
apron may also be desirable as protection against radiated heat and sparks.
3. Hot sparks or metal can lodge in rolled up sleeves, trousers cuffs, or pockets.
Sleeves and collars should be kept buttoned, and open pockets eliminated
from the front of clothing.
4. Protect other personnel from hot sparks with a suitable non-flammable
partition or curtains.
5. Use goggles over safety glasses when chipping slag or grinding. Chipped
slag may be hot and can travel considerable distances. Bystanders should
also wear goggles over safety glasses.
FIRES AND EXPLOSIONS - Heat from a flame can act as an ignition source. Hot
slag or sparks can also cause fires or explosions. Therefore:
1. Remove all combustible materials well away from the work area
or completely cover the materials with a protective non-flamma-
ble covering. Combustible materials include wood, cloth, sawdust,
liquid and gas fuels, solvents, paints and coatings, paper, etc.
2. Hot sparks or hot metal can fall through cracks or crevices in
floors or wall openings and cause a hidden smoldering fire on
the floor below. Make certain that such openings are protected
from hot sparks and metal.
3. Do not weld, cut, or perform any other hot work on materials, containers, or
piping until it has been completely cleaned so that no substances on the
material can produce flammable or toxic vapors. Do not do hot work on
closed containers. They may explode.
4. Have fire extinguishing equipment handy for instant use, such as a garden
hose, a pail of water or sand, or portable fire extinguisher. Be sure you are
trained in its use.
5. After completing operations, inspect the work area to be sure that there are
no hot sparks or hot metal which could cause a later fire. Use fire watchers
when necessary.
6. For additional information, refer to NFPA Standard 51B, "Fire Prevention in
Use of Cutting and Welding Processes", which is available from the National
Fire Protection Association, Batterymarch Park, Quincy, MA 02269.
FUMES AND GASES - Fumes and gases, particularly in confined spaces, can
cause discomfort or injury. Do not breathe fumes or gases from welding
or cutting, Therefore:
1. Always provide adequate ventilation in the work area by natural or mechanical
ventilation means. Do not weld, cut, or gouge on materials such as
galvanized steel, stainless steel, copper, zinc, lead, beryllium, or cadmium
unless positive mechanical ventilation is provided. Do not breathe fumes
and gases from these materials.
2. If you develop momentary eye, nose, or throat irritation while operat-
ing, this is an indication that ventilation is not adequate. Stop work at
once and take necessary steps to improve ventilation in the work area.
Do not continue to operate if physical discomfort persists.
3. Refer to ANSI/ASC Standard Z49.1 listed below for specific ventilation recommendations.
EQUIPMENT MAINTENANCE - Faulty or improperly maintained equipment,
such as torches, hoses and regulators, can result in poor work, but even more
important, it can cause injury or death through fires. Therefore:
1. Always have qualified personnel perform the installation, troubleshooting,
and maintenance work. Do not operate or repair any equipment unless you
are qualified to do so.
2. Keep all oxy-fuel equipment free of grease or oil. Grease, oil, and other similar
combustible materials, when ignited, can burn violently in the presence of
oxygen.

heat and wet conditions, oil or grease, corrosive atmospheres and inclement
weather.
4. Keep all safety devices in position and in good repair.
5. Use equipment for its intended purpose. Do not modify it
in any manner.
GAS CYLINDER HANDLING - Gas cylinders, if mishandled, can rupture or
explode violently. Sudden rupture of a cylinder, valve or relief device can
injure or kill you. Therefore:
1. Use the proper gas for the process and use the proper pressure reducing
regulator designed to operate from the compressed gas cylinder. Do not
use adaptors to mount the regulator on the cylinder. Maintain hoses and
fittings in good condition. Follow manufacturer's operating instructions for
mounting the regulator to the gas cylinder.
2. Always secure cylinders in an upright position by chain or strap to suitable
hand trucks, benches, walls, post, or racks. Never secure cylinders to work
tables or fixtures where they may become part of an electrical circuit.
3. When not in use, keep cylinder valves closed. Have the valve protection cap
in place on top of the cylinder if no regulators is installed. Secure and
move cylinders by using suitable hand trucks. Avoid rough handling
of cylinders.
4. Locate cylinders away from heat, sparks, or flame of a welding,
cutting, or gouging operation. Never strike an arc on a cylinder.
5. For additional information, refer to CGA Standard P-1, "Precau-
tions for Safe Handling of Compressed Gases in Cylinders:, which
is available from the Compressed Gas Association, 1235 Jefferson Davis
Highway, Arlington, VA 22202.
