The minimum diameter of a tag line that should be used to control loads is a critical safety measure. A tag line serves as a means to manage and guide loads safely during lifting operations, ensuring that workers can maintain a safe distance from potentially hazardous movements.

A diameter of not less than 16mm is recommended because it provides enough strength and durability to withstand the forces exerted on the line during the handling of heavy loads. This specification helps to prevent the tag line from breaking or becoming ineffective when subjected to the tension created by controlling a load, especially in dynamic work environments.

Choosing a line with a diameter smaller than 16mm may compromise safety and control, posing risks not only to the operators handling the load but also to other personnel on-site. Therefore, this specification is put in place to enhance safety protocols in excavation and lifting operations.
