The OSHA regulation at 29 C.F.R. §1910.1000(d) requires employers to determine the cumulative exposure of workers to certain gases over an 8-hr work shift using the following formula:
E = CaTa + CbTb + …. + CnTn
8
E is the equivalent exposure for the work shift,
C is the concentration during any period of time in which the concentration remains constant, and
T is the duration of time in hours of the exposure.

The regulation further stipulates that no employee can be further exposed to the gas when the value of E exceeds the 8-hr time-weighted average limit set for the given substance. If a worker is exposed to ammonia concentrations throughout the workday as follows, 125 ppm for 4 hr; 75 ppm for 2 hr; and 25 ppm for 2 hr, determine the equivalent exposure (E):
