What is a potential hazard when working near microwave antennas?

When working near microwave antennas, exposure to harmful electromagnetic radiation is indeed a significant hazard. Microwave antennas emit microwave radiation, which can have adverse effects on human health if proper safety precautions are not in place. This type of radiation can lead to thermal injuries and may also have non-thermal effects that are still being studied. Workers must adhere to established safety protocols and maintain a safe distance from the antennas during operation to minimize the risk of exposure.

The other hazards, while still relevant in various contexts, do not specifically correlate with the operations involving microwave antennas. For instance, risk of falling objects is more associated with elevated work sites or improper securing of tools. Noise-induced hearing loss is generally a concern in environments with high levels of noise, rather than radiation exposure. Allergic reactions to equipment materials, while possible, are not a primary concern when it comes to microwave antennas and their operation. Understanding and mitigating the risks of electromagnetic radiation exposure is critical for the safety of technicians working with or near these antennas.
