What are common ignition sources to control around munitions?

• A. Open flames and smoking.
• B. Sparks, friction, heat, static electricity, open flames, smoking, and electrical equipment not rated for explosive atmospheres.
• C. Water exposure only.
• D. Ignition sources are not relevant to munition safety.

Answer: (B)

Understanding which ignition sources must be controlled around munitions is about eliminating anything that could start a fire or detonation in storage and handling areas. The best choice lists a full range of ignition sources: open flames and smoking, sparks, friction, heat, static electricity, and electrical equipment not rated for explosive atmospheres. Each category covers common ways energy can be released: open flames and smoking are direct fire risks; sparks and friction can occur from tools or contact; heat from hot surfaces or equipment; static electricity can build up and discharge during handling; and non-rated electrical gear can spark or overheat in explosive atmospheres. Together they reflect the real safety measures used to prevent unintentional initiation. The other options are incomplete or misleading: focusing only on open flames and smoking misses other significant sources; water exposure does not inherently ignite munition materials; and claiming ignition sources aren’t relevant contradicts fundamental safety principles.
