How should lighting be configured in magazines?

• A. Standard ceiling lighting.
• B. Gas lanterns.
• C. Adequate, explosion-rated lighting that does not produce sparks or heat, with protected wiring.
• D. Unprotected wiring with bright bulbs.

Answer: (C)

In magazines, lighting must be explosion-proof and non-sparking to prevent ignition of any powders or propellants present. The space contains energetic materials, so any heat, flame, or electrical arc could start a fire or explosion. Gas lanterns have an open flame and are inherently unsafe in such a environment. Regular ceiling lighting may not be rated for explosive atmospheres and can still generate heat or sparks. Unprotected wiring is a serious hazard because damaged insulation can create sparks. Explosion-rated lighting is designed to avoid sparks and excessive heat, and when paired with protected wiring, it minimizes ignition risk. That's why the safest and most appropriate choice is lighting that is explosion-rated, non-sparking, and wired with protected conductors.
