I included the following references....

> 1910.1450(d)(1) ---employer shall measure the employee's exposure to any
> substance regulated by a standard which requires monitoring if there is
> reason to believe that exposure levels for the substance routinely exceed
> the AL.
>
> 1910.1450 (C) --for lab use of OSHA regulated substances, the employer
> shall assure that the lab employees' exposure to such substances do not
> exceed the PEL.
>
> Using methylene chloride as an example, 1910.1052 (d)(1) states--where MC
> is present in the workplace, the employer shall determine each employee's
> exposure by taking a personal breathing zone sample or taking
> representative sample.
>
> Based on this information (and other information in the standard) do you
> conduct air monitoring for employees working in a fumehood?  If not, is
> this because you do not anticipate levels which exceed the action level
> per 1910.1450(d)(1) above?  How do you document this rationale /
> assessment?
