According to AFI 91-202, what should a supervisor ensure?

• A. Knowledge of all hazards in operations.
• B. Conveys emergency procedures to workers only, not casuals or visitors.
• C. Maintains housekeeping standards only.
• D. Knowledge of all hazards in operations, convey emergency procedures to workers, casuals, and visitors, maintain housekeeping standards, know steps for abnormal conditions, and enforce personnel/explosive limits.

Answer: (D)

Supervisors must ensure safety by making sure everyone on site understands the hazards, emergency procedures are communicated to workers, casuals, and visitors, housekeeping standards are kept, there are clear steps for handling abnormal conditions, and personnel and explosive limits are enforced. This combination covers the full range of preventive actions needed to protect people and property: awareness of hazards, rapid and correct emergency response by all who may be on site, a clean and orderly work area to reduce accidents, readiness for unusual or dangerous situations, and strict adherence to limits on who can handle or be exposed to explosives. When these elements are in place, it significantly lowers the risk of mishaps and keeps the operation under proper control.
