What is a key precaution when using open-flame effects near wooden stage elements?

• A. Use wood without any protective materials.
• B. Use fire retardant materials and maintain clearance.
• C. Keep flames away from audience only.
• D. Operate only with higher humidity.

Answer: (B)

Open-flame effects near wooden stage elements pose a real fire risk because wood can ignite from heat, sparks, or embers. The best precaution is to use fire-retardant materials around the flame area and keep a safe clearance between the flame source and any wooden elements. Fire-retardant materials are treated to resist ignition and slow flame spread, giving crews time to detect and suppress any incident. Maintaining clearance reduces heat transfer and prevents sparks from reaching wood. This approach fits into a broader safety plan with trained operators and proper extinguishing equipment. The other options miss essential protections: using unprotected wood raises ignition risk; keeping flames away from the audience alone doesn't protect wooden set pieces; and higher humidity by itself isn’t a reliable or sufficient safety measure.
