Exposure control areas.
You must establish temporary or permanent exposure control areas where airborne concentrations of benzene are above, or can be reasonably expected to be above, the permissible exposure limits (PELs) for benzene by doing all the following:
(1) Post signs in accordance with WAC 296-849-11010.
(2) Distinguish the boundaries of exposure control areas from the rest of the workplace in any way that minimizes employee access.
(3) Allow only authorized personnel to enter exposure control areas.
Note: | • You may use permanent or temporary enclosures, caution tape, ropes, painted lines on surfaces, or other materials to visibly distinguish exposure control areas or separate them from the rest of the workplace. |
• When distinguishing exposure control areas you should consider factors such as: | |
– The level and duration of airborne exposure. | |
– Whether the area is permanent or temporary. | |
– The number of employees in adjacent areas. |
Reference: | If exposure control areas are established, go to Respirators, WAC 296-849-13045. |
