Which elements constitute approved work controls in the safety policy's three components?

• A. LOTO, isolation, and barricading.
• B. Hazard assessment, PPE, and training.
• C. Personal safety gear and signage.
• D. Maintenance schedules and logs.

Answer: (A)

Approved work controls focus on preventing hazards from harming workers by controlling the hazard at its source and limiting access to the area. Lockout/Tagout stops equipment from being energized or reenergized, so it can’t start unexpectedly during maintenance. Isolation physically disconnects the equipment from all energy sources, ensuring there is no energy available to cause harm. Barricading creates a visible boundary around the work area and prevents unauthorized or unqualified people from entering, reducing exposure to hazards. Together, these three controls address both energy hazards and access, providing a comprehensive safeguard during maintenance.

Other options rely on protective gear or planning steps rather than controlling the hazard directly. PPE protects the worker but doesn’t eliminate the hazard itself, hazard assessment and training are important planning activities, and maintenance schedules and logs are records rather than active controls.
