Introduction

In the construction and public work sectors the cutting torch is a valuable and useful tool designed to quickly and efficiently cut metals in a variety of applications. Before going any further we want to remind you that it’s important to consult your local OSHA requirements for cutting and welding safety, and always refer to the safety requirements for your organization.

Disclaimer

Working with oxygen fuel cutting and welding torches presents a number of hazards making the use of proper safety and operating procedures mandatory. This program is not an attempt to train you in all the hazardous conditions that can exist in welding and cutting operations. This can’t be accomplished in a short program like this so be sure you’ve been thoroughly trained in the safe use of your equipment before attempting to use any welding or cutting equipment.

Pre-job Checklist, Fireproofing, Work Environment

Now, before starting to work, be sure the floor itself is fireproof, such as concrete. Of course, from time to time you may have to work on a wood floor which will require that it be covered with sand or wetted down with water.

Heat resistant material can also be used to protect certain areas. Asbestos has been used in the past, but due to the health risks associated with asbestos other fireproof materials should be used to protect against sparks, and hot metal.

Work benches should be constructed with fireproof tops. Frequently fire bricks or medal grids are used as a working surface. Since cutting operations consume oxygen adequate ventilation must be used to prevent oxygen deficiency, flammable or toxic gases, or fumes while working in confined spaces. Remember when working in confined spaces be sure that all the requirements for work in confined spaces are followed as confined spaces can become a death trap.

Oxygen and fuel cylinders should be secured or chained to the cylinder cart, bench, or work area to prevent an accidental fall. If a cylinder should fall there’s a serious risk of injury as the regulator or cylinder neck may be broken off causing the cylinder to take off like a rocket. A cylinder jetting wildly around on the job site is a truly terrifying experience.

Personal Protective Equipment

As with all jobs, proper personal protective equipment is imperative for protection from flying slag, sparks, and of course, bright light. Goggles with tempered lenses shaded number 5 or darker help protect the eye and allow better visibility. Remember swap meet sunglasses or street glasses should never be worn as they provide no protection from the many potential eye hazards.

Protective sleeves, gloves, and aprons should be worn to guard the skin and clothing against burn or flying sparks. Never wear clothing with oil or grease on them as the spark can quickly set your clothing on fire. Safety shoes are also a must as the hazard of hot slag can quickly burn through tennis shoes. Not to mention the potential of dropping heavy material on your foot.

Fire Prevention

When working with oxygen fuel operations fire prevention should be a prime consideration.

• First, never use grease or oil on or around any oxygen fuel equipment. In the presence of oxygen even a tiny amount can cause an explosion and major fire.
  
  
• Two, keep flames and sparks well away from cylinders and hoses. If you’ve been around cutting operations very long you know this rule is frequently ignored.
  
  
• Three, keep combustible material such as rags and paper well away from cutting operations as sparks can fly great distances.
  
  
• Next, use heat resistant material to protect nearby walls and floors.
  
  
• Always have a multi-purpose fire extinguisher on hand, and know how to use it. Also, check it regularly to be sure it will function in the event of a fire.
  
  
• Only use oxygen fuel equipment with the gases it was designed to work with. Never open oxygen cylinder valve more than one complete turn, and keep the cylinder wrench on the cylinder valve so that it can be quickly turned off in an emergency.
  
  
• Never test gas leaks with a flame. Use only approved leak detection solutions.
  
  
• Finally, when your work is completed check the area for possible smoldering materials that can cause a fire after you’ve left.
