Administrative Controls

Administrative controls reduce the exposure duration of individuals, thereby reducing the employee’s overall exposure. Two alternatives are employee rotation and work shift modification. There are, however, drawbacks to these controls including:

  • it may not be feasible to rotate employees with sufficient frequency to comply with the exposure limit (more frequently than every two hours is generally considered to be infeasible),
  • the workers may not be versatile enough to perform different jobs, and
  • greater management involvement is required.

Modifications in shift patterns are never easy. Effective exposure reduction by these techniques also requires that a constant contaminant level be present. For intermittent processes or where production rates vary between shifts, the differing levels of activity cause fluctuations in contaminant concentrations that may make average exposures difficult to quantify or predict. Because of these limitations, administrative controls should be considered secondary to engineering controls and other work practices that may be more effective in controlling exposures.
