Administrative controls are the second most effective method of hazard control,
Administrative controls limit workers' exposures by scheduling shorter work times in contaminant areas or by implementing other "rules". These control measures have many limitations because the hazard itself is not actually removed or reduced. Administrative controls are not generally favored because they can be difficult to implement, maintain and are not a reliable way to reduce exposure. When necessary, methods of administrative control include:
- Restricting access to a work area.
- Restricting the task to only those competent or qualified to perform the work.
- Scheduling maintenance and other high exposure operations for times when few workers are present (such as evenings, weekends).
- Using job-rotation schedules that limit the amount of time an individual worker is exposed to a substance.
- Using a work-rest schedule that limits the length of time a worker is exposed to a hazard.
