Yes, worker exposures to beryllium at the new PEL, STEL, and action level can be reliably measured using existing sampling and analytical methods.
OSHA has carefully reviewed the available scientific literature and expert testimony contained in the rulemaking record on the ability of modern sampling and analytical methods to reliably measure beryllium at the new PEL, STEL, and action level. OSHA and NIOSH methods for analyzing beryllium are able to measure concentrations at the new PEL and action level with acceptable precision.
