The standard(s) for explosion prevention measures include which NFPA standards?

• A. NFPA 68
• B. NFPA 69
• C. NFPA 69/NFPA 68
• D. NFPA 12

Answer: (C)

Explosion prevention measures rely on two complementary standards: one that focuses on preventing explosions and another that provides a venting path if a deflagration occurs. NFPA 69 covers Explosion Prevention Systems, detailing how to design, install, and maintain systems that prevent explosions from starting or escalating, including controls, purging, inerting, ignition source management, and interlocks. NFPA 68 covers Explosion Venting, specifying when and how to vent pressure safely to protect equipment and personnel during a deflagration. Using both standards together gives a complete approach: you implement prevention measures to reduce or eliminate the chance of an explosion, and you have venting provisions to relieve pressure if a deflagration does occur. NFPA 12 is not about explosion prevention and does not fit this context.
