In December of 1991, OSHA issued a standard to guard against occupational exposure to bloodborne pathogens. This standard, part 1910.1030 of the Code of Federal Regulations was published in the Federal Register.
On November 27, 2001, OSHA published a compliance directive 2-2.69 that now includes the revisions to the original standard.
These regulations are law!
Many states have an additional occupational exposure statute that must be followed as well. Your employer should be familiar with all applicable rules and standards to reduce your risk of infection with bloodborne pathogens in the performance of your job.
