Who is designated as the only qualified individual to establish working limits in on track safety?

The individual designated as the only qualified person to establish working limits in on track safety is the roadway worker employee in charge. This role is critical because it encompasses the responsibility of ensuring safety protocols are followed and that working limits are correctly defined to protect all workers in the area.

The roadway worker employee in charge is trained and certified specifically for this function, which includes understanding the complexities of the work environment, signaling protocols, and communication with train operators to prevent accidents. They must be knowledgeable about the regulations governing safety procedures and possess the authority to make decisions that directly affect the safety of the work zone.

Other roles, such as safety officers or maintenance personnel, may play important parts in the overall safety management and oversight but do not have the specific training or authority to establish working limits. This makes the role of the roadway worker employee in charge critical to maintaining on track safety.
