Atmospheric testing
Employers should carry out atmospheric testing of the air around an abrasive blasting site for dust, especially when a toxic or hazardous material is involved.
Testing can be done before abrasive blasting work starts and during work to monitor the extent of effectiveness of controls and any additional action needed.
The four main components of atmospheric testing are:
- collection of an air sample by a trained specialist
- laboratory analysis
- interpretation of the results and comparison with National exposure standards for atmospheric contaminants in the occupational environment (non-Queensland Government link)
- taking action
Monitoring by trained personnel should be conducted in all abrasive blasting applications as part of the initial risk assessment process. This will enable the appropriate respirator to be selected and will ensure that workers and other people are not exposed to harmful dust concentrations.
The selection, use and maintenance of respiratory devices should be undertaken in accordance with AS/NZS 1715 Selection, Use and Maintenance of Respiratory Protective Devices (non-Queensland Government link).
