WELDING AND
CUTTING
The performing of welding and cutting
operations exposes the employee to certain hazards. No welding units
should be used by any plant employee except those regularly employed
to do such work. Such operations also expose structures and items to
damage by fire. When performing welding and cutting operations
follow these safety rules:
Gas Welding &
Cutting
1. When performing gas welding and
cutting operations a portable fire extinguisher should be
immediately available as well as approved goggles must be
worn.
2. Gas cylinders should never be moved
or stored unless valve protection caps are in place. Exception: When
the gas cylinders are secured to a wheeled cart.
3. Store and move cylinders in a
secured upright position.
4. Do not take cylinders into confined
spaces.
5. Make sure regulations, hoses,
couplings & tip connections are in good condition, (no breaks,
damaged or cracked glass, or oil contamination). Never burn the head
out of a drum, use a drum cutting tool.
6. Do not interchange hose connections
between fuel gas and oxygen.
7. Always use a spark lighter when
lighting a gas torch. Do not use matches or hot work to light
torches.
8. Do not weld or cut in or near
flammable materials, especially paints, dusts, gases or vapors. If,
for any reason, it is necessary to solder or weld a tank which has
previously contained gasoline or any other flammable liquid, the
tank must first be filled with water and the operation performed
while the tank is full except for a small air space around the spot
to be welded. No one except those authorized should undertake this
kind of work.
9. Do not use compressed gas for
comfort, cooling, blowing dust from clothing, or for cleaning off
work areas.
10. Always wear suitable eye and face
protection when engaged in welding, cutting, or heating
materials.
11. When leaving torch unattended, turn
off gas valves at cylinders.
12. Check area before and after welding
for fire hazards.
13. To prevent backflash, backflash
preventors should be installed between the torch and the gas
cylinders. Some newer gas cylinder regulators have built-in
backflash preventors.
14. Report faulty or defective
equipment to your supervisor. |
