Which statement best explains the purpose of RF safety signage?

• A. To warn that RF exposure levels may exceed safe limits
• B. To indicate a general safety area
• C. To indicate a fire hazard
• D. To designate a restricted zone

Answer: (A)

RF safety signage is meant to warn that radiofrequency exposure could exceed safe limits. It communicates the risk so workers know to limit time near the source, follow exposure guidelines, and use any required protective measures. RF energy can cause health effects, including tissue heating, so the primary purpose of the sign is to alert about potential exposure rather than marking a general area, a fire hazard, or a restricted zone.
