Proper training is essential. No one should be permitted to handle a compressed gas container or utilize a compressed gas until such handler or user is familiar with the proper equipment to us in association with the gas, and the hazardous properties of the gas. A review of all label information and appropriate MSDS should be completed as a part of your training. Handling compressed gas is dangerous, and you should be familiar with the hazards before handling compressed gas.

  • Never identify content by container color, except in the case of medical gases. Color codes are not uniform throughout the industry.
  • Cylinder contents must be identified by a decal, label, tag, or stenciling.
  • Never abuse gas cylinders by using them for rollers, blocks, striking arcs, etc.
  • Never attempt to lift the cylinder by the valve protection cap.
  • Do not store or transport compressed gases in closed vans or automobiles.
  • Always secure cylinders in storage and in use to insure against their tipping over.
  • Never store cylinders near sources of heat.
  • Never remove the valve protection cap until the cylinder is secured (chained or belted in place) and is ready for use.
  • Never tamper with the cylinder valve or cylinder pressure relief device. If defective, do not attempt repairs.
  • Never attempt to trans fill gas from one cylinder to another, or mix any gasses in a cylinder.


State, local building and fire codes will apply to the installation and storage of compressed gas. It is important to understand which codes apply to your facility, and assure that the codes are met. The following information covers some of the major requirements of many of the codes for the storage co compressed gases.

  • Store all cylinders in designated areas that are secured.
  • Incompatible gases shall be separated from each other by a distance of at least 20 feet or by an incombustible barrier at least 5 feet high having a fire resistance rating of at least one-half hour. Incompatible gasses are those that are toxic, flammable, or oxidizing.
  • Oxidizers shall be stored a minimum of 20 feet from flammable gases or combustible materials, or separated by a barrier at least 5 feet high having a fire resistance rating of at least one-half hour.
  • Outdoor storage shall be kept clear of dry vegetation and combustible materials for a minimum distance of 15 feet.
  • Cylinders stored outside shall not be placed on the the ground or on surfaces where water can accumulate. They should be protected from the weather, and shaded in areas where extreme temperatures prevail.
  • Storage areas shall be provided with physical protection from vehicle damage.
  • Do not store cylinders near elevators, truck-loading platforms, gangways, or under operating cranes, or other areas where they can be damaged by falling objects.
  • Storage indoors should be in dry, well ventilated, cool, areas free from contact with corrosive materials or fumes, preferably constructed of fire-resistant materials.
  • Cylinders shall not be exposed to temperatures in excel of 125 degrees F.
  • Smoking and open flames shall not be permitted in oxygen and flammable gas storage areas or within 20 feet of storage areas.



  • Almost all accidents involving compressed gas cylinders are a result of improperly using, transporting, storing or handling the compressed gas cylinder.
  • Moving compressed gas cylinders in cars or vans can be dangerous. AVOID IT.
  • Never move gas cylinders in closed spaces such as car trunks- it could cause an explosion or fire.
  • Fix gas cylinders in an upright position, with windows open to ventilate.
  • If a cylinder is put on its side it must be made unmovable. Drive with windows open.
  • Make sure the cylinder is secured in the body of the vehicle, not the trunk, either vertically or horizontally so that it will not move relative to the vehicle.
  • Drive directly to your destination-no intermediate stops. Gas cylinders should not remain in the vehicle longer than necessary for transportation.
  • Take a route which is most direct. If possible, avoid routes with heavy traffic.
  • When destination is reached turn off engine, set emergency brake, put transmission into park or first (with manual transmission) and get assistance in removing the cylinder from the auto or van, depending on its size and weight.
  • If returning the cylinder by auto or van, follow directions that apply to pick-up and transportation of the full cylinder.
  • Do not operate any spark of flame producing devices or smoke within 25 feet of any oxidizing gas or flammable gas.

Proper specifications and guidelines referring to transporting, handling and storing cylinders can be found on ODOT's website. Follow strict the regulations by OSHA and ODOT when moving and using compressed gas. Regulations and codes may vary depending on state.
