Preventing Sensitization and Disease from Beryllium Exposure WARNING! Workers exposed to particles, fumes, mists, or solutions from beryllium-containing ma-terials may develop beryllium sensitization or chronic beryllium disease, a potentially disabling or even fatal respiratory disease.
The method was evaluated using beryllium oxide spiked onto Whatman #541 cellulose and nylon filters at levels of (0, 0.02, 0.1, 0.2, 0.3, 0.4, 1.5, 3.0, and 6.0) μg (five samples at each level). of Energy sites suspected to be contaminated with beryllium. Field samples measured by portable fluorometry were
Beryllium recovery was 98.2% with a measurement precision, S r, of 0.008 [2]. This method is an improvement of S339 [3], which was validated over the range of 2.68 to 11.84 μg/m 3 using a 40-L sample.
This is the docket for the draft NIOSH methods for Beryllium. NIOSH Method 7704 (air sampling) and Method 9110 (wipe sampling) and the backup data report for these methods. Beryllium is a health hazard with many uses in the ceramics industry and in military artillery.

removed from any possible beryllium contamination. Any area afected by the dissolution or detection soluti ns must be immediately washed with plenty of water. Ammonium bifluoride will etch glass, so it is essential that all ammonium b fluoride solutions be contained in plastic labware. Avoid exposure by c
