procedures,besuretoreadandfollowthesafetyprecau-
tions listed below as well as all other manuals, material
safety datasheets,labels,etc.FailuretoobserveSafety
Precautions can result in injury or death.
PROTECT YOURSELF AND OTHERS --
Some welding, cutting, and gouging
processes are noisy and require ear
protection.Thearc,likethesun,emits
ultraviolet (UV) and other radiation
and can injure skin and eyes. Hot metal can cause
burns. Training in the proper use of the processes
and equipment is essential to prevent accidents.
Therefore:
1. Always wear safety glasses with side shields in any
workarea,evenifweldinghelmets,faceshields,and
goggles are also required.
2. Use a face shield tted with the correct lter and
cover plates to protect your eyes, face, neck, and
ears from sparks and rays of the arc when operating
or observing operations. Warn bystanders not to
watch the arc and not to expose themselves to the
rays of the electric-arc or hot metal.
3. Wear ameproof gauntlet type gloves, heavy long-
sleeve shirt, cuess trousers, high-topped shoes,
and a welding helmet or cap for hair protection, to
protect againstarcraysandhot sparks orhot metal.

glasses.
FIRES AND EXPLOSIONS -- Heat from
ames and arcs can start res. Hot
slagor sparkscan alsocauseres and
explosions. Therefore:
1. Remove all combustible materials well away from
the work area or cover the materials with a protec-
tivenon-ammablecovering.Combustiblematerials
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 oors or wall openings and cause a hid-
