?■ INDUSTRIAL HYGIENE ELEVATED EXPOSURE NOTICE working in close quarters in basement levels it may not be possible to stand very far away and this may be why the result above was so high. Additional methods of control, such as increased ventilation and, where feasible, wetting down should be implemented to minimize the dust exposure during use of Brokk machines in basement levels.
I am available to consult on controls for this and other operations.
It is important that proper use of respiratory protection be enforced until such time as is feasible controls are identified and can be implemented to reduce exposures to levels below the shift adjusted OEL. Sampling records indicate that respiratory protection was in use by all workers during these exposure evaluations.
These notifications are provided to you to ensure that this information is provided to employees and that appropriate control, PPE, and training action is taken by the contractor.
