device and liquid petroleum gas cylinders should have an operational spring-loaded pressure relief valve. Acetylene cylinders must be fitted with a fusible plug in the neck of the cylinder and must always be stored and used in an upright position.

Control measures
    * Avoid work being carried out in oxygen-enriched (over 23 per cent) or oxygen-depleted (under 19.5 per cent) atmospheres.
    * Keep the work area well ventilated, particularly in low lying areas and roof spaces where gases can accumulate.
    * Use an air supplied respirator, particularly in confined spaces.
    * Monitor the atmosphere to check it is free of harmful contaminants and contains an adequate oxygen level. See 3.10 of this Code for more information about confined spaces.
    * Check cylinder fittings, hoses and connections are not damaged or in poor condition.

3.7 Noise

Regulation 57: A person conducting a business or undertaking must manage the risk to health and safety relating to hearing loss associated with noise. The person conducting a business or undertaking must ensure that the noise a worker is exposed to at the workplace does not exceed the exposure standard for noise.
Regulation 58: Audiometric testing must be provided to a worker who is frequently required to use personal hearing protectors to protect the worker from hearing loss associated with noise that exceeds the exposure standard for noise.
Exposure to high noise levels can cause permanent hearing loss. Equipment for performing welding can generate varying levels and frequencies of noise that may cause workers to be exposed to noise that exceeds the exposure standard. Specifically plasma arc welding generally exceeds the noise levels generated by other welding activity and ranges between 98 to 112 dB(A).
The exposure standard for noise in relation to hearing loss, is defined in the WHS Regulations as an LAeq,8h of 85 dB(A) or an LC,peak of 140 dB(C). There are two parts to the exposure standard for noise because noise can either cause gradual hearing loss over a period of time or be so loud that it causes immediate hearing loss.
The most effective control measure is to remove the source of noise completely. If this is not possible, modify equipment and processes to reduce the noise, or isolate the source of noise from people by using distance, barriers, welding bays and sound absorbing surfaces (types of engineering control measures).
If these measures are not reasonably practicable, implement administrative control measures which limit the amount of noise people are exposed to and how long they are exposed to it.
Lastly, personal hearing protection must be provided to protect workers from any remaining risk.
