Fire extinguishers transported under UN1044 and oxygen cylinders transported for emergency use under UN1072 may include installed actuating cartridges (cartridges, power device of Division 1.4C or 1.4S), without changing the classification of Division 2.2, provided the aggregate quantity of deflagrating (propellant) explosives does not exceed 3.2 grams per cylinder.
Hazard Communication Standard requirements for …
Under the standard, a compressed gas (defined as a gas or mixture of gases having, in a container, an absolute pressure exceeding 40 psi at 70 degrees, or a liquid having a vapor pressure exceeding 40 psi at 100 degrees), is considered a physical hazard and therefore, is considered a hazardous chemical.
If a gas cylinder is involved in a fire: Do not approach or attempt to move the cylinder or operate the valve – keep away. Raise the alarm. Evacuate the immediate area and keep others away. Contact the Fire & Rescue Service. Inform the Fire & Rescue Service of the location, quantity and type of gases involved.

What happens to a gas cylinder in a fire?
Gas cylinders in fires. Gas cylinders are designed to contain gases under pressure. However, cylinders are at risk of failure and may rupture due to the combined effects of increasing pressure and weakening of the cylinder wall when exposed to extreme heat – therefore it is important that users understand how to respond in the event of a fire.
