Occupancy/occupancies

The law of mass action has been successfully applied to many drug dose-response relationships since the early work of Clark. The systematic relation between the dose of a drug and the magnitude of its response is based on three assumptions (1) response is proportional to the level of receptor occupancy (occupancy theory), (2) one drug molecule combines with one receptor site, and (3) a negligible fraction of total drug is combined with the receptors. These assumptions must also apply to Beidler s equation. 

Occupant vulnerabilities are one of the key factors in determining the levels of both individual and aggregate risks for building occupants. Occupant vulnerabilities are used in risk screening as discussed in Chapter 4 and are used in detailed risk assessments.

Ergonomic issues affect aU types of people and occupations. Occupations such as nursing assistants and registered nurses laborers and freight, stock and material movers janitors and cleaners maintenance and repair workers and heavy and tractor-trailer truck drivers are among the most vulnerable populations, representing more than 25 percent of MSD cases. In 2012, MSD cases accounted for a median of 12 days away from work compared to nine days for all other types (Bureau of Labor Statistics, 2013).
