and transport compressed gas cylinders in the upright position
with the valve protective caps on.
Secure cylinders in portable service upright with a chain.
- Never weld in areas with limited or restricted
air supply (confined space) without prior approval from the
Department of Safety and Environmental Affairs.
- Do not store or place cylinders where
they will be exposed to heat, flame, impact, electric arcs or
circuits, high temperature process equipment or sparks.
regulators and pressure gauges only with gases for which they
are designed and intended. Do
not attempt to repair or alter cylinders, valves, or attachments.
a "Defective" tag on any fuel gas cylinder in which leaks occur
and immediately remove it from service and store outdoors.
gas cylinders are close to welding or cutting operations, place
a fire resistant shield between the cylinders and these operations.
an "Empty" tag on all empty cylinders and store them separately
from full ones.
removing a regulator from a cylinder valve, close the cylinder
valve and release the gas from the regulator.
proper eye and/or face protection when welding.
- Inspect torches in
use at the beginning of each working shift for leaking shutoff
valves, hose couplings, and tip connections.
- Use friction lighters
or other approved devices to light torches. Never use matches
or hot work to light torches.
- Shut gas cylinders
off when operations are suspended for any substantial period
of time, such as during lunch or overnight.
Upon completion of welding operations, warn other workers
of the location of hot metal.
- Cut or weld only in
areas that are or have been made fire safe.
- Where practicable,
relocate all combustibles at least 35 feet from the work site. Where relocation is impracticable, combustibles
should be protected with flame-proofed covers or otherwise shielded
with suitable guards or curtains.
- Maintain suitable fire
extinguishing equipment ready for use while welding and cutting
are being performed.
- Make sure fire watchers
are employed whenever welding or cutting is performed in locations
where other than a minor fire might develop.
WELDING AND CUTTTING
- Protect workers or
other persons adjacent to the welding areas from the rays by
erecting noncombustible or flameproof screens or shields, or
have them wear appropriate safety goggles.
- Make sure arc welding
and cutting cables are insulated, flexible and capable of handling
the maximum current required by the operations, taking into
account the duty cycles.
- Make sure ground connections
are mechanically and electrically adequate to carry the current.
- When electrode holders
are left unattended, remove electrodes and place holders to
prevent employee injury.
- Keep the power supply
switch in the off position when arc welders or cutters leave
or stop work or when machines are moved.
- When arc welding is
performed in wet or high humidity conditions, use additional
protection, such as rubber pads or boots, against electric shock.
- If you are exposed to UV radiation, make sure your
skin is covered completely to prevent ultraviolet burns and
damage. Be sure your
helmets and hand shields do not have leaks, openings or highly
- Perform soldering activities
only if you are trained and authorized to do so.
- Always wear personal
protective equipment, including safety glasses, when soldering.
- Always solder in well-ventilated
- Minimize soldering
fumes by using the lowest acceptable wattage and holding the
electrode perpendicular and as close to the work surface and
- Position yourself while
welding or cutting so that your head is not in the fumes.
- Remove all nearby flammable
or combustible materials before striking an arc or lighting
- Keep welding areas
free of equipment and machines that could cause trips or falls.
