When compressed gas cylinders are introduced into a work area or building for the first time e-mail fire@ucl.ac.uk with details of the type of gas, number of cylinders and the location where they will be used and stored. This information will be used by the Fire Safety Team to update the fire and rescue information packs available in the Premises Information Box.


Whenever possible, select the smallest size of gas cylinder available. When siting gas cylinders in the workplace, make sure that: gas cylinders

  • they are supported with chains or straps in an upright position;
  • they are protected from mechanical damage and sources of heat;
  • the gas supply is turned off at the cylinder when not in use;
  • the area where the cylinder is used is well ventilated;
  • oil, grease or jointing compound is NOT used on cylinder fittings.


If possible, arrange to have gas cylinders delivered to the point of use. If this is not possible, make sure that:

  • anyone moving cylinders is trained to do it safely;
  • a trolley is always available to move cylinders from the storage area to the work area;
  • personal protective equipment is worn to protect feet and hands. More.......
  • gas cylinders are never moved with the valve open.


Cylinders should ideally be stored outside the building. If this is not possible, the number of stored cylinders should be kept to a minimum.

Access to cylinder storage areas should be restricted to authorised people only. The storage area should be well ventilated and cylinders should be stored in the following way:

restricted access

      close the cylinder valve and replace dust caps;

      support the cylinders with chains or straps in an upright position;

      empty cylinders should be labeled 'empty' and stored separately from full ones;

      segregate gases according to type and compatibility (refer to the safety data sheet if in doubt).


sign flammable


Doors to areas where compressed gas cylinders are used and stored should display hazard warning signs indicating the presence of compressed gas cylinders and any additional hazard associated with the type of gas e.g. flammability. This information is essential to fire and rescue personnel when carrying out operations

See: TN095 Laboratory Fire Safety Signs (General Hazard Warning)
