CBD is primarily an occupational lung disease, but it has been reported in household contacts of beryllium workers and individuals living near beryllium facilities.

Workplace Standards

Air

The OSHA regulation for beryllium and its compounds is an 8-hour time-weighted average (TWA) of 2 micrograms (as beryllium) per cubic meter of air (2 µg/m3).

An employee should not be exposed to a concentration of beryllium and beryllium compounds exceeding 5 µg/m3.

The 30-minute maximum peak level is 25 µg/m3.

NIOSH recommends that beryllium be treated as a potential human carcinogen and advises a 10-hour TWA not to exceed 0.5 µg/m3.

Environmental Standards
Air

Beryllium has been designated a hazardous air pollutant under the Clean Air Act. According to EPA regulations, beryllium emissions from stationary sources cannot exceed 10 g (0.022 lbs) over a 24-hour period.

Ambient air concentrations averaged over a 30-day period near stationary sources must not exceed 0.01 µg/m3.

Water

The EPA advisory for beryllium in water is less than 68 nanograms per liter (ng/L) for consumption of 2 L of ambient water per day.
