What is the minimum separation between electrical and manual fire methods?

• A. 15 feet
• B. 50 feet
• C. 25 feet
• D. 10 feet

Answer: (C)

Keeping electrical firing equipment physically separate from manual firing operations is about preventing one system from affecting the other. The minimum separation is twenty-five feet, which provides a safe buffer against arcing, heat, or stray sparks from an electrical firing line reaching a manually triggered device. It also gives operators room to move, troubleshoot, and manage cables without stepping into the other system’s zone. If the distance were much smaller, a fault or misfire in the electrical system could more easily ignite or interfere with manual devices; if it were much larger, it could be unnecessarily cumbersome for the show layout. Twenty-five feet offers a practical safety margin that reduces risk while remaining workable on most setups.
