OSHA requires feasible engineering OR administrative controls, and mandatory hearing protection when the PEL is exceeded. The maximum time a person can be exposed for a noise level 100 dB can be calculated as. 1.0 mg/m3 b. This means that, for limited periods, a worker may be exposed to concentration excursions higher than the PEL, so long as the TWA is not exceeded and any applicable excursion limit is not exceeded. The Substantial Evidence TestIII. A PEL is usually given as a time-weighted average (TWA), although some are short-term exposure limits (STEL) or ceiling limits. NIOSH uses a hierarchy of control to reduce or remove hazardous noise. Action level means employee exposure, without regard to the use of respirators, to an airborne concentration of lead of 30 micrograms per cubic meter of air (30 µg/m 3) calculated as an 8-hour time-weighted average (TWA).
