a "Exposure" means measured exposure or potential for exposure at the indicated level.

b Powered, air-purifying respirator.

3.6.2 Other Personal Protective Equipment

The use of other PPE (e. g., gloves, lab coats, or coveralls), as determined by the ES

* Airborne exposures to beryllium equal or exceed the AL.

* Surface contamination exceeds, or is presumed to exceed, the housekeeping standard (i.e., 3 µg Be/100 cm2).

All workers required or wanting to use PPE shall follow the requirements of Document 11.1, which requires that the selection of PPE be documented. The processes of Document 2.2 shall also be followed.

3.7 Facilities and Equipment

Facilities used for beryllium work should be designed to minimize the spread of beryllium aerosols and to minimize beryllium contamination and opportunities for beryllium exposure. Therefore, such facilities have the following features:

* Beryllium work areas that are at negative pressure relative to non-beryllium work areas (e.g., beryllium machine shops).
