There are different classes of particulate filters, depending on the particulate material. Some types of atmospheres contain concentrations of hazardous substances that places the worker in immediate danger because these concentrations would impair the ability to leave the work area (self rescue) or potentially cause irreversible health effects, including serious injury or death in a matter of minutes. Workers with beards, long sideburns, or even a two-day stubble may not wear respirators because the hair breaks the seal between the skin and the respirator mask. Laboratory personnel are also under medical surveillance and may require immunizations for the microbes they work with. Discharges from industrial sources are the second major category of point-source pollution which strictly regulated by which piece of legislation?
