What is a best practice for a worker pulling wire by hand?

Lubricating wires before pulling is a critical best practice as it significantly reduces friction and the potential for damage to both the wire and the conduit through which it is being pulled. When wires are properly lubricated, the pulling process becomes smoother, making it easier to manage long runs and minimize the risk of the wire kinking or breaking. Additionally, lubrication helps to protect the insulation on the wires, ensuring their integrity and reliability over time. This practice not only enhances efficiency but also promotes safety, as it reduces the physical strain on the worker.

The other choices present approaches that either lack safety considerations or do not enhance the likelihood of a successful wire pulling operation. For instance, relying solely on protective gloves does not address other safety aspects, such as proper body mechanics and equipment utilization. Using manual strength without support could lead to physical injuries or improper installation, while working unprotected could expose an individual to unnecessary risks, undermining the learning experience. Thus, lubricating wires stands out as the best practice in this scenario.
