Which statement best describes safe misfire handling?

• A. Relight the existing charge when possible
• B. Disarm the misfire after inspecting the device
• C. Move equipment away and immediately dispose of the charge
• D. Secure the area and wait for qualified personnel to assess the situation

Answer: (D)

When a device fails to fire, its status is uncertain and could still be dangerous. The safest approach is to secure the area, keep others away, and wait for qualified blasting personnel to assess the situation. Trained blasters have the knowledge, tools, and approved procedures to determine whether the misfire can be safely managed, disarmed, or disposed of, and to coordinate any necessary follow-up steps. Relighting the charge is risky because a misfired device might detonate if re-energized, and the wiring or timing could be compromised. Disarming without proper training and equipment can trigger a blast or cause delayed detonation. Simply moving equipment away and disposing of the charge bypasses the required identification and controlled handling that professionals must perform. Securing the area and awaiting qualified personnel minimizes risk and ensures safety protocols are properly followed.
