What is the required no-smoking distance from designated areas?

• A. No smoking within 50 meters
• B. No smoking within 50 feet
• C. No smoking within 10 feet
• D. No smoking within 100 feet

Answer: (B)

The main idea here is keeping a safety buffer around designated areas to prevent ignition from smoking or flame sources. The required no-smoking distance is 50 feet. This size of buffer provides a practical margin to account for heat, embers, or sparks that could reach flammable materials, even with some wind or small errors in keeping distance. In this context, feet are the standard unit, so 50 feet is the established rule. A 50-meter distance would be unnecessarily large for typical operations, 10 feet is too close to reliably prevent ignition, and 100 feet goes beyond the standard requirement.
