For challenge agents such as asbestos that require laboratory analysis with its inherent time lag to quantify airborne concentrations, this compliance posture magnifies the worker protection challenges for non-routine activities such as decommissioning and demolition.
Lessons Learned: Where workplace concentration measurements demonstrate that airborne concentrations are in excess of applicable occupational asbestos exposure limits, the employer must be able to demonstrate BOTH:
- That respiratory protection in use by the occupants was sufficiently protective, AND
- That all feasible engineering and work practice controls have been applied to minimize
