What is a significant feature of a connector in safety systems?

A significant feature of a connector in safety systems is that it may be an integral part of the system. In the context of occupational safety, especially in the construction industry, connectors are crucial components that ensure the effectiveness and reliability of fall protection systems. They serve as the link between various parts of the safety equipment, such as harnesses, lanyards, and anchorage points.

Having connectors as integral parts of the system enhances the overall structural integrity and functionality of the safety equipment. It ensures that all elements work in unison to provide the necessary protective measures against falls or other hazards. Depending on the system's design and application, connectors can include various types of hardware, not limited to carabiners, which indicates versatility in safety design.

In contrast, the other options suggest limitations that do not reflect the essential role of connectors in safety systems. For instance, the notion of connectors being standalone or only carabiners ignores the multitude of configurations and types of connectors available that work together as part of a comprehensive safety system. Additionally, the requirement for connectors to be removable from the harness does not apply universally since some connectors are designed to remain attached permanently for optimal safety.
