This makes beryllium a greater exposure hazard than other toxic metals. Beryllium is very toxic. OSHA's PEL for beryllium is the same limit the Atomic Energy Commission established for the metal back in 1949. Incidence rates among employees who machine beryllium rise as high as 10 to 14 percent. The latency period for CBD is generally 10 to 15 years, but it may take as long as 30 years from time of exposure to development of disease.
Some people also experience sensitivities to very small amounts of beryllium.
Don't be surprised if a debate heats up over whether any exposure to the material is safe. We've seen the combination of investigative reporting and scientific research spark emotional and political reactions to substances in the past, and it might happen again with beryllium. Greater controls could be mandated eventually, and may be prudent even without government action. Exposure fears could boil over in some workplaces. Greater precautions for working with the material are being recommended.
