Shock and burn safety equipment for EMFR hazards in controlled areas with frequencies below 30 MHz may include which items?

• A. Grounding wires, electrical insulation, and safety matting.
• B. Radiation shielding, personal aroma gear, and hats.
• C. Fire extinguishers, ear protection, and gloves.
• D. PPE only without grounding or insulation.

Answer: (A)

The main idea here is how to prevent electrical shock and skin burns in areas where non-ionizing hazards from low-frequency EM exposure are present. For voltages and fault currents at frequencies below 30 MHz, the most effective protection comes from engineering controls that stop or limit current through a person and provide a safe path for fault currents. Grounding wires give any fault current a low-impedance route to earth, so a fault doesn’t cause a dangerous touch voltage on equipment surfaces. Electrical insulation adds a barrier between live parts and people, making it harder for current to flow through the body if contact occurs. Safety matting provides additional separation from conductive floors and helps reduce potential pathways for current to reach a worker, contributing to overall insulation at the work surface. Together, these elements form a practical, layered approach to reduce shock risk in EMFR-controlled areas. The other options mix items that don’t directly address shock prevention in this context, or rely on PPE alone. Radiation shielding or hats/ear protection don’t stop fault currents; PPE alone won’t prevent current from flowing through the body. Fire extinguishers are for fire safety, not electrical shock.
