What is the central focus of the bloodborne pathogens standard?

OSHA's Bloodborne Pathogens standard as revised pursuant to the Needle stick Safety and Prevention Act of 2000, illustrates approaches to safeguard workers against the health hazards caused by the bloodborne pathogens.  

Its requirements include items like universal precautions, exposure control plans, personal protective equipment, engineering and work practice controls, hepatitis B vaccination, housekeeping, laboratories, hazard communication and training, post-exposure follow-up, and recordkeeping.  

The standard implies requirements on employers whose workers can be rationally expected to contact blood or other probable infectious substances, like certain body fluids, and human tissues.
