can accumulate– this could be done by ensuring windows are open where necessary and ventilation and extraction systems are on and are fully functional
    * purging
    * using an air-supplied respirator, particularly in confined spaces
    * checking cylinders, cylinder fittings, hoses and connections to ensure that they are not damaged or in poor condition – this might include checking fittings and hoses for signs
      of corrosion or degradation or spraying them with a small amount of detergent solution
      or leak-detection spray and looking for bubble formations which may indicate the presence
      of a gas leak.

4.3 Maintaining control measures
Regulation 37: A person conducting a business or undertaking must ensure that the implemented control measures remain effective. This includes checking that the control measures are fit for purpose; suitable for the nature and duration of the work and are installed and used correctly.
Maintenance of control measures may involve the following:
    * regular inspections of control measures
    * supervision to ensure workers are using the control measures properly
    * preventative maintenance and testing programs for chemical storage and handling systems
    * periodic air monitoring to ensure that engineering and administrative controls remain effective.
Maintenance procedures should include mechanisms for workers to report defective control measures as soon as they are identified so that prompt remedial action can be taken.

Preventative maintenance and integrity testing
Regulation 363: A person conducting a business or undertaking must ensure, so far as is reasonably practicable, that a system used at the workplace for the use, handling or storage of hazardous chemicals is used only for the purpose for which it was designed, manufactured, modified, supplied or installed and is operated, tested, maintained, installed, repaired and decommissioned having regard to the safety or workers and other persons at the workplace.
Systems for the storage and handling of hazardous chemicals generally require on-going maintenance and testing to ensure that they continue to be safe for the intended use and that they maintain their operational integrity. Such systems include, but are not limited to, reaction vessels, chemical transfer lines, pumps, spill bunding and storage tanks, filters etc.
To ensure that the integrity of chemical handling systems is preserved, planned maintenance programmes should be designed and carried out at regular intervals, consistent with manufacturer's instructions or advice provided by other competent persons. If this is not reasonably practicable, inspections and maintenance should be carried out annually.
Examples of preventative maintenance and integrity testing might include:
    * Inspection of glass linings on steel or metal alloy reaction vessels to ensure there are no cracks or holes which might allow contact of incompatible materials with the metal vessel.
    * Regular checking of bursting (rupture) discs and pressure-relief systems on pressure
