The Hierarchy of Controls
Warnings
Warnings such as signs, barrier tape, and alarms help employees become aware of hazards. In most hierarchy of control models, warnings are included with administrative controls. It’s also important to know that warnings do not prevent exposure. They only warn students and others that a hazard exists. Warnings are only useful if they are not ignored.
Work Practice Controls
Work practice controls include procedures and appropriate cleaning and disinfection practices. Good housekeeping practices should be used to help prevent surface contamination and hygiene facilities and practice to protect workers from exposure.
Important work practice controls include:
- staggering and alternating schedules;
- reducing maximum occupancy in all areas of the building;
- closing indoor communal use spaces;
- promoting hand hygiene;
- implementing cleaning and disinfection protocols; and
- posting signs and messages to promote protective measures.
