Oxygen/ Fuel Cutting
Welding and cutting operations use fire or
combustion as a basic tool. The process is
very useful when properly controlled.However, it can be extremely destructive if not
performed correctly in the proper environment.
The work area must have a fireproof floor.
Work benches or tables used during welding or
cutting operations must have fireproof tops.

Oxygen/ Fuel CuttingUse heat resistant shields or other approved
material to protect nearby walls or unprotected
flooring from sparks and hot metal.
Keep an approved fire extinguisher of theproper size and type in the work area. Inspect
it regularly to ensure that it is in proper working
order. Know how to use the fire extinguisher.Move combustible materials away from the
work site. If you can not move them, protect
them with fireproof covers.

WARNING!Never perform welding or cutting
operations on a container that has heldtoxic, combustible or flammable liquids orvapors.
Never perform welding or cuttingoperations in an area containingcombustible vapors, flammable liquids, or
explosive dust.

Good housekeeping practices
improve the safety of any work
area. They are essential to the safetyof welding and cutting operations due
to the potential hazards involved.
Keep all welding and cuttingapparatus clean and free of grease,
oil, and other flammable substances.

Warning!Never allow oxygen to contact
grease, oil, or other flammablesubstances. Although oxygen byitself will not burn, these substances
become highly explosive.They can ignite and burn violently in
the presence of oxygen.

Ventilate welding and cutting work areasadequately.
Maintain sufficient air flow to preventaccumulation of explosive or toxicconcentrations of gases.
Welding or cutting operations using
certain combinations of metals, coatings,and gases generate toxic fumes. Userespiratory protection equipment in these
circumstances.

Oxygen/Fuel Cutting
Gas flames produce infrared radiation
which may have a harmful effect on
the skin and especially on the eyes.Select goggles or a mask with
tempered lenses shaded 5 or darker
to protect your eyes from injury andprovide good visibility of the work.

Wear flame resistant clothing,
protective gloves, sleeves, aprons
and safety shoes to protect skin andclothing from sparks and slag.
Keep collars, sleeves and pockets
buttoned.DONOT roll up sleeves or cuff pants.

Oxygen/ Acetylene Safety
1. This process can KILL you and others.
Be sure to follow all safety rules.
2. Be sure to completely shut down thecutting torch when the job is completed.
3. Keep all oils and grease away from the
regulators. When oxygen is compressed
with a petrochemical, it becomes highly
reactive and can explode. Imagine a
500lb bomb exploding in front of you. Will
there be any pieces to pick up?
