Preventing Chronic Beryllium Disease and Beryllium Sensitization

The National Institute for Occupational Safety and Health (NIOSH) is conducting
a public review of the NIOSH draft document entitled NIOSH Alert: Preventing
Chronic Beryllium Disease and Beryllium Sensitization, NIOSH Docket Number
NIOSH-120. The overall goal of the review is to enhance the quality and
credibility of Agency recommendations by ensuring that the scientific and
technical work underlying these recommendations receives appropriate public
review. This guidance document does not have the force and effect of law.

Beryllium is a lightweight metal with many remarkable properties, including
heat resistance and conductance, electrical conductance, flexibility,
formability, neutron moderation, x-ray transparency and lubricity. Exposure to
beryllium can lead to sensitization, a cell-mediated allergic-type response,
and cause a granulomatous lung disease called chronic beryllium disease.

The Alert describes the nature of the lung disease and other health effects
that can occur from exposure to beryllium and beryllium-containing materials
and recommend steps companies and workers should take to minimize the health
risk to workers. This guidance document does not have the force and effect of
law.
