       * using engineering control measures, for example, installing ventilation systems
         to capture or remove airborne contaminants. Refer to 4.1 of this code for more information on ventilation.
    * Implement administrative control measures, for example procedures to handle hazardous chemicals safely.
    * Provide appropriate respiratory protection.
Check the SDS for welding rods and wires to identify which gases and fumes are released during welding. Further information about controlling airborne contaminants is available in the Fume Minimisation Guidelines published by the Welding Technology Institute of Australia.

Exposure standards

Regulation 49: A person conducting a business or undertaking must ensure that no person at the workplace is exposed to a substance or mixture in an airborne concentration that exceeds the exposure standard for the substance or mixture.
Exposure standards represent airborne concentrations of a particular substance or mixture that must not be exceeded. There are three types of exposure standard:
    * 8-hour time-weighted average
    * peak limitation
    * short term exposure limit.
Exposure standards are based on the airborne concentrations of individual substances that, according to current knowledge, should not cause adverse health effects nor cause undue discomfort to nearly all workers.
Chemicals with workplace exposure standards are listed in the Workplace Exposure Standards
for Airborne Contaminants. These exposure standards are also available from the Hazardous Substances Information System (HSIS) on the Safe Work Australia website. The HSIS database contains additional information and guidance for many substances. Although exposure standards may also be listed in Section 8 of the SDS, you should always check the Workplace Exposure Standards for Airborne Contaminants or HSIS to be certain.
Guidance on interpreting exposure standards is available in the Guidance on the Interpretation
of Workplace Exposure Standards for Airborne Contaminants.
To comply with the WHS Regulations, monitoring of workplace contaminant levels for chemicals with exposure standards may need to be carried out.

Monitoring airborne contaminant levels

Regulation 50: A person conducting a business or undertaking must ensure that air monitoring is carried out to determine the airborne concentration of a substance or mixture
at the workplace to which an exposure standard applies if:
    * the person is not certain on reasonable grounds whether or not the airborne concentration
      of the substance or mixture at the workplace exceeds the relevant exposure standard; or
    * monitoring is necessary to determine whether there is a risk to health.
Air monitoring is the sampling of workplace atmospheres to obtain an estimate of workers' potential inhalation exposure to hazardous chemicals.
Air monitoring can be used:
    * when there is uncertainty about the level of exposure
    * to indicate whether exposure standards are being exceeded or approached
    * to test the effectiveness of the control measures.
Air monitoring should
