The contents of pressure bottles are generally indicated by the colour. The contents of the pressure bottles are also stamped on the bottles.

  • Bottle valves must never be lubricated.
  • Bottles must never be thrown or otherwise exposed to knocks, blows or strong loads. Therefore, they must be secured properly to prevent tipping, rolling or falling over.
  • Pressure bottles must be protected against strong heat. They must be positioned in such a way as to be easily removable in the event of a fire.
  • Only the bottles to be used for the work being carried out may be present at the work site. The valves must be closed on bottles not being used.
  • The valve’s protective cap or collar must be fitted securely during transportation.

Oxygen bottles must be kept scrupulously clear of any contamination with oil or grease. The valve must be opened slowly.
When using e.g. acetylene gas, a check valve must be fitted before the manometer.

The Danish Emergency Management Agency has issued technical regulations on how to design indoor and outdoor stores of larger quantities of gas and inflammable liquids.

Aerosol cans

Aerosol cans must not normally be exposed to temperatures in excess of 40 °C or for any other overload during use and transportation. Cans must not be punctured or discarded until they are completely empty.
