Toxic Gases

• Toxic gases must be used in ventilated cabinets.
• Pipe and systems for toxic gas must be checked for integrity (1)
• Check carefully for leaks.
• Risk assessments must be completed.

(1) Use a safe gas to test system.

Gas Cylinders - General Siting Guidance (for non toxic gases)

The hierarchy of control must be considered during the process of risk assessment when considering the best location for a gas cylinder.

Oxygen

• Oxygen must be used with care in metal pipework systems –particles will ignite in oxygen flowing at high speed , so turn on systems slowly.

General Guidance once a location has been identified (other gases)

• Place the cylinder in an upright position
• Place the cylinder in an unobstructed position
• Place away from sources of heat or cold [ cryogens]
• Place the cylinder tag on the indicator hook
• Fit the correct regulator to the cylinder.
• Check regulator control is in low pressure position.
• Check all connections for tightness.
• Open the cylinder delivery valve slowly.
• Adjust the regulator slowly to desired pressure.
• Check for leaks.
