However, unintended exposure to drugs in the manufacturing workplace can cause significant health hazards to workers. It is important to protect the workforce from these delete- rious effects by limiting exposure to an acceptable level, the occupational exposure limit (OEL). OEL is defined as airborne concentrations (expressed as a time-weighted average for a conventional 8-h workday and a 40-h work week) of a substance to which nearly all workers may be repeatedly exposed (for a working lifetime) without (a) Identify THREE (3) possible biological or chemical hazards exposed to the workers in the pharmaceutical manufacturers.
