Is it safe to operate 2-way radio equipment within a 300-foot radius of a blasting area?

• A. Yes
• B. No
• C. Only on specific channels
• D. It depends on weather

Answer: (B)

The main safety idea is that the blast zone must remain as a controlled, distraction-free area. Within 300 feet of blasting, using two-way radios is restricted because any electrical or radio activity could pose a risk of unintended initiation or interference with the blasting operation, and it can distract workers during a critical procedure. Weather or channel choices don’t change this risk. The safe practice is to avoid operating radio equipment in that radius and rely on established, approved communication methods outside the blast area.
