Before determining the proper procedure for confined space entry, a(n) ____ must be performed.

• A. Hazard review
• B. Site survey
• C. Risk assessment
• D. Job safety analysis

Answer: (A)

Identifying hazards in the confined space is the crucial first step. A hazard review looks at all potential dangers—atmospheric risks (like oxygen deficiency or toxic gases), flammable vapors, engulfment hazards, energy sources that could release unexpectedly, physical obstacles, and entry/exit limitations—and determines the controls you’ll need. By reviewing hazards first, you can decide what procedures, monitoring, ventilation, PPE, training, and permits are required to enter and work safely. Other options describe useful safety activities, but they don’t zero in on the space-wide hazards in the way a hazard review does. A site survey checks layout and access; a risk assessment considers probability and severity more broadly; a job safety analysis focuses on steps of a task. So, conducting a hazard review provides the essential foundation for setting the proper confined space entry procedure.
