What standards are applicable to Industrial Hygiene?
The field of Industrial Hygiene references two major criteria when evaluating exposures of individuals to chemical or physical agents. One criterion is the regulatory OSHA PEL. A PEL refers to the maximum concentration of a substance to which OSHA allows occupational exposure. Another exposure parameter is the TLV, which is an advisory value espoused by the ACGIH. It represents the most recent data from scientific exposure studies. A PEL or TLV is compared against the sampled concentration as collected over an average workday. These values should not be exceeded to protect the health of the individual.
