Part 4 Chemical Hazards, Biological Hazards and Harmful Substances

Section 29 Restricted area

This section lists requirements applicable only to restricted areas. By definition, these are areas where there is a reasonable likelihood that airborne concentrations of asbestos, silica, coal dust or lead will exceed their OELs. Restricted areas are therefore subject to additional conditions.

The employer is responsible for ensuring that the release of particulate is kept at a minimum by using ventilation, wetting to suppress dust, or other methods. An employer must provide workers in the restricted area with protective clothing that prevents contamination of the other clothing they are wearing. The employer must ensure workers use the clothing provided.

It is also the employer’s responsibility to ensure that workers do not take fibrogenic dust or lead particulate with them when leaving the restricted area. Section 23 already requires an employer to provide the facilities, including showers, that workers need to remove the contamination before workers leave the work site. Both the employer and worker have a duty to ensure that the worker is decontaminated prior to leaving the restricted area.
