Beryllium metal Metal: A hard, brittle, gray-white solid.

The IDLH value for beryllium has not changed, but other information on this page has been changed, including updated exposure limits, updated respirator recommendations, and a new NIOSH Carcinogen Policy. For the most up to date information on Beryllium see the NIOSH Pocket Guide to Chemical Hazards.

05 μg to 4 μg of beryllium on the sampling media. Alternative ratios of dissolution solution and detection solution may be used for anal zing alternative ranges of beryllium concentration. To test a range of 0.005 μg to 0.4 μg of beryllium on the sampling media, 0.4 mL …

Because beryllium sensitization can occur at very low levels of exposure, the level of residual beryllium contamination remaining was not considered in the determination. During the course of the radiation dose reconstruction process, data capture efforts were focused on processes and conditions relative to radioactive materials.

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.

Control Technology and Exposure Assessment for Occupational Exposure to Beryllium: Abrasive Blasting with Coal-slag

Apr 6, 2007 · of Energy sites suspected to be contaminated with beryllium. Field samples measured by portable fluorometry were also analyzed using hot-plate digestion and ICP-AES

Occupational exposure to beryllium occurs at places where the chemical is mined, processed, or converted into metal, alloys, and other chemicals. Workers engaged in machining metals containing beryllium, recycling beryllium from scrap alloys, or using beryllium products may also be exposed to higher levels of beryllium.

Beryllium RTECS # DS1750000 CAS # 7440-41-7 See: NMAM or OSHA Methods Updated September 2018 Molecular Weight 9.01 Molecular Formula Be

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.
