1. Oxygen/ Fuel Cutting and Welding By Ryan Saucier
2. Oxygen/ Fuel cutting torches can be used to cut, pierce and gouge mild steel.
3. 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.

33. Oxygen/ Acetylene Cutting Torch Stored in Flammable Liquids Cabinet
35. 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?
36. Remember Safety is Job # 1
