Gas Safety Checklist

The beginning of the year is an excellent time to perform a comprehensive review of safety practices within your operations.  We at CeeKay have compiled a list of commonly encountered safety topics in regards to our industry.  As your technical resource for all things welding and gas related please contact your sales representative or give us a call at 314-644-3500 if you have any specific questions in which you would like to address.

This checklist is not all-inclusive. This list should be used as precautions and general guidelines. Each company or employee should reference OSHA, US Department of Labor, and CGA for specific rules and regulations. 


  • Are all employees instructed in the location of appropriate fire extinguishing equipment and proper procedures in case of an accident or emergency?

General Information & Storage

  • Are cylinders stored in upright positions and immobilized by chains or other means to prevent them from being knocked over?

LP Gases stored appropriately per the manufacturer as to ensure safety relief is in contact with vapor space.

  • Are cylinders stored away from highly flammable substances such as oil, gasoline, or waste?
  • Are flammable gases separated from oxidizing gases in storage areas?

20 Ft away or with separate non-combustible barrier (such as a wall) at least 5 feet high with a fire-resistance rating of at least one-half hour.

  • Are oxygen and fuel gas cylinders separated by minimum of 20 feet when in storage? A fire-resistant partition between cylinders can also be used at least 5 feet high.
  • Are storage rooms for cylinders dry, cool and well-ventilated? The storage rooms should be fire resistant and the storage should not be in subsurface locations. Cylinders should be stored in secure areas of temperatures below 125 degrees fahrenheit, away from radiators or other sources of heat.
  • Are cylinders stored away from incompatibles ; excessive heat, continuous dampness, salt or other corrosive chemicals, and any areas that may subject them to damage?
  • Is the storage area premaritally posted with names of the gases stored in the cylinders?
  • Do all compressed gas cylinders have their contents and precautionary labeling clearly marked on their exteriors?
  • Are charged or full cylinders labeled and stored away from empty cylinders?


  • Are all hoses, torches, couplings, gauges, and other equipment inspected at the beginning of each work session?
  • Are welders and gas users provided with appropriate and adequate personal protective equipment, trained to use it, and using it?
  • Are regulators, torches, and point of use for all gases being evaluated supplied with proper approved safety devices like flashback arrestors and check valves?


  • Use ANSI-approved eye protection and refer to safety data sheets for any additional protective equipment.
  • Regulators must be free of oil, grease, or other contaminants. Do not use plumbers tape or other adhesives on CGA fittings.
  • A flash arrestor should be installed in the line when flammable gas is being used, if possible.

Manifolds, Valves, Piping, & Regulators

  • Are all compressed gas cylinder valve covers in place when cylinders are not in use?
  • If a cylinder can take a valve protection cap it must be on at all times except when connected for use.
  • Distribution lines and their outlets must be clearly labeled including: Name of the Gas and Directional Arrow.
  • Piping or hoses should be examined regularly. Do not use unnecessarily long hoses and keep hoses kink free.
  • A flash arrestor should be installed in the line when flammable gas is being used.

For more information please contact a Cee Kay Supply representative and refer to the proper regulatory governing authority or industry standards for use.
