    * have a water hose or fire extinguisher handy to put out any small fire close to the cylinder –
      a water spray can also be used to keep the cylinder cool in the event of a fire.
To ensure the in-built safety features of a cylinder function correctly, cylinders of liquefied flammable gas need to be positioned so that the safety relief device is in direct contact with the vapour space within the cylinder. Keep the cylinder upright, unless the design permits other positions – this depends on the position and operation of the relief device. If in doubt check
the manufacturer's or supplier's instructions.
For further guidance on safe storage and handling of gas cylinders, refer to AS 4332: The storage and handling of gases in cylinders.
Further advice on storage and handling of specific gases is available from the following Australian Standards:
    * AS/NZS 2022: Anhydrous ammonia – Storage and handling
    * AS 1894: The storage and handling of non-flammable cryogenic and refrigerated liquids
    * AS/NZS 2927: The storage and handling of liquefied chlorine gas
    * AS 3961: The storage and handling of liquefied natural gas
    * AS/NZS 1596: The storage and handling of Liquefied Petroleum (LP) gas

UNODOURISED LIQUEFIED PETROLEUM GAS (LP GAS) OR DIMETHYL ETHER
Although the sense of smell should not be relied upon to detect gas leaks and hazardous chemicals, it can often provide some level of warning to nearby workers in some instances.  Unodourised LP Gas can be particularly hazardous and, due to the absence of any discernable odour, it cannot be detected by the sense of smell. Dimethyl ether (DME), a highly flammable gas, is often used as a propellant for LP gas.
The risks from storing and using unodourised LP Gas can be reduced by using the following control measures:
    * Keep the storage and handling of unodourised LP Gas or DME to a minimum, and restrict uses to those for which no less hazardous alternative is available (e.g. aerosol propellant)
    * The area where it is stored and handled should be well ventilated, or in a room designed
      for that purpose fitted with explosion ventilation, or in the open. Access to these areas should be restricted to essential personnel.
    * Gas detection equipment should be installed to detect gas where an explosive atmosphere could develop and provide an automatic alarm before dangerous levels of gas are reached so that immediate action may be taken. The gas detector should emit an audible sound
      and have a visual
