Which safety precaution should be taken when handling compressed air?

Using ear protection when handling compressed air is essential for safety due to the potential noise levels generated by compressed air systems. When operating pneumatic tools or machinery that relies on compressed air, the sound can reach levels that may cause hearing damage over time. Therefore, wearing ear protection helps mitigate the risk of noise-induced hearing loss, making it a critical safety precaution in environments where loud pneumatic equipment is used.

While other precautionary measures such as turning off power before checking the system, and using gloves when operating pneumatic tools, are also important for different safety reasons, they do not specifically address the risks associated with noise from compressed air environments. Wearing appropriate clothing for mobility does not contribute to safety regarding the handling of compressed air and could potentially lead to other hazards. Thus, prioritizing ear protection is vital in promoting overall safety when working with compressed air.
