What does the mnemonic FISHED stand for in explosives safety?

• A. Fuels, Ignition, Spark, Heat, Electricity, Detonation
• B. Friction, Impact, Shock, Heat, Electronic, Discharge
• C. Friction, Impact, Shock, Heat, Electronics, Discharge
• D. Friction, Impact, Sound, Heat, Electronic, Discharge

Answer: (B)

In explosives safety, FISHED represents six ways an explosive can be initiated: Friction, Impact, Shock, Heat, Electrical (Electronic), and Discharge. The option listing Friction, Impact, Shock, Heat, Electronic, and Discharge exactly matches these initiation modes, including both electrical energy and discharge (such as static electricity). The other options introduce terms not part of this mnemonic (like fuels or sound) or mix up the electrical terminology, so they don’t fit the standard six initiation mechanisms.
