When Plan Examiner deals with situations involving explosive hazards they should reference NFPA _____ for guidance.

• A. 61 & 69
• B. 61
• C. 69
• D. 70

Answer: (A)

When explosive hazards are involved, you need guidance that covers both preventing explosions and protecting people and property if one occurs. NFPA 61 provides the standards for the prevention of fires and explosions in the handling, storage, and transport of explosives, helping ensure proper conditions and procedures to reduce ignition sources. NFPA 69 complements that by detailing explosion prevention systems, including design features like venting, isolation, inerting, and suppression to prevent or mitigate an explosion. Using both standards gives a complete framework for plan reviews dealing with explosives—addressing how materials are handled and how controls are put in place to prevent and manage an explosion. NFPA 70, the National Electrical Code, governs electrical installations and isn’t the primary guide for explosive-hazard protection.
