Explosive stimuli (FISHED) include which of the following?

• A. Friction, Induction, Strain, Heat, Electronic, Destruction.
• B. Friction, Ignition, Shock, Elevation.
• C. Fission, Ionization, Shear, Humidity.
• D. Friction, Impact, Shock, Heat, Electronic, Discharge.

Answer: (D)

Explosive stimuli are the different ways energy can be delivered to an explosive to trigger it. The FISHED mnemonic captures six main paths: Friction, Impact, Shock, Heat, Electronic, and Discharge. Friction and impact/shock are mechanical energies that can generate enough localized heat and pressure to reach initiation. Heat provides thermal energy to ignite sensitive material. Electronic and discharge refer to electrical energy—sparks or electrical discharges—that can supply the needed energy to start the reaction. The option that lists all six of these categories best represents the recognized initiation stimuli. Other options mix in terms that aren’t part of the standard FISHED set, so they don’t fully align with the established initiation pathways.
