What is the primary purpose of a safety harness?

The primary purpose of a safety harness is to prevent falls. When working at heights, such as on telecom towers, the risk of falling is significant. A safety harness is designed to securely attach the worker to a stable structure or anchor point, thereby minimizing the risk of a fall and protecting the individual from injury. This crucial safety equipment is an integral part of fall protection systems, ensuring that in the event of a slip or unpredicted movement, the worker remains safely attached and suspended rather than losing balance and falling.

While the other options mention supporting loads, facilitating climbing, or reducing fatigue, these do not capture the main function of a safety harness in a safety context. The focus here is primarily on fall prevention, making it essential for workers to utilize harnesses correctly to ensure their safety while performing tasks at heights.
