Final answer:
The best protection to prevent a fall when removing a section of guardrail is securing a harness and lanyard to an anchor point, in compliance with OSHA standards, rather than options which could increase risk.
Step-by-step explanation:
The question addresses the issue of workplace safety, particularly in the context of preventing falls when a worker is required to remove a section of guardrail in order to remove materials from a fork truck. When considering the options provided for the best protection against falls, securing a harness and lanyard to an adequate anchor point is the most effective measure. This is in accordance with OSHA's standards that require employers to provide proper fall protection equipment like safety harnesses and lines.
Using a forklift without safety equipment, standing on the top rail of the guardrail, or removing the entire guardrail would not provide the same level of protection and would likely increase the risk of falls and injuries. It is imperative to follow safety guidelines when working at heights including staying a safe distance from the edge not leaning too far over railings, making sure that dropped objects do not pose a risk to people or vehicles below, and ensuring that no property damage occurs as a result of the work being conducted. Employers must also ensure the workplace is free of recognized hazards and provide proper training and equipment to ensure worker safety.
