Scheduling off-shift maintenance work is an example of which type of control?

• A. Hazard control
• B. Administrative control
• C. Engineering control
• D. PPE

Answer: (A)

Scheduling off-shift maintenance work focuses on changing how and when the work is done to reduce exposure. In the safety controls hierarchy, this is an administrative control: it uses policies, procedures, and work practices to lower risk rather than altering the equipment or relying on personal protective equipment. By performing the maintenance when systems are offline or during periods of lower activity, and by limiting the number of workers on site, the chance of encountering energized equipment or arc flash is reduced. This kind of planning and scheduling is a procedural approach that complements engineering controls (like barriers or interlocks) and PPE, but it itself is not a change to the hardware or a piece of protective gear.
