Title: Oxygen/ Fuel Cutting and Welding

Oxygen/ Fuel Cutting and Welding
  • By Ryan Saucier

2
Oxygen/ Fuel cutting torches can be used to cut,
pierce and gouge mild steel.

Oxygen/Fuel Cutting Guidelines
4
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.

5
Oxygen/ Fuel Cutting
  • Use 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 the proper
    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.

6
Oxygen/Fuel Cutting
  • WARNING!
  • Never perform welding or cutting operations on a
    container that has held toxic, combustible or
    flammable liquids or vapors. 
  • Never perform welding or cutting operations in an
    area containing combustible vapors, flammable
    liquids, or explosive dust.

7
Oxygen/Fuel Cutting
  • Good housekeeping practices improve the safety of
    any work area.  They are essential to the safety
    of welding and cutting operations due to the
    potential hazards involved.
  • Keep all welding and cutting apparatus clean and
    free of grease, oil, and other flammable
    substances.

8
Oxygen/Fuel Cutting
  • Warning!
  • Never allow oxygen to contact grease, oil, or
    other flammable substances.  Although oxygen by
    itself will not burn, these substances become
    highly explosive. 
  • They can ignite and burn violently in the
    presence of oxygen.

9
Oxygen/Fuel Cutting
  • Ventilate welding and cutting work areas
    adequately. 
  • Maintain sufficient air flow to prevent
    accumulation of explosive or toxic concentrations
    of gases. 
  • Welding or cutting operations using certain
    combinations of metals, coatings, and gases
    generate toxic fumes.  Use respiratory protection
    equipment in these circumstances.

10
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 and provide good visibility of the work. 

11
Oxygen/Fuel Cutting
  • Wear flame resistant clothing, protective gloves,
    sleeves, aprons and safety shoes to protect skin
    and clothing from sparks and slag. 
  • Keep collars, sleeves and pockets buttoned. 
  • DO NOT 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 the cutting 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?
