What is the minimum length of gaffs allowed?

The minimum length of gaffs allowed is 1.25 inches. This specification is important for ensuring safety and effectiveness when linemen are climbing utility poles. Gaffs, which are metal spikes attached to a climber's boots, provide critical support and grip while ascending and working at heights.

A length of 1.25 inches is considered the standard because it provides adequate penetration into pole materials such as wood, ensuring that linemen can rely on their gaffs for safety. If gaffs were shorter than this standard, they might not provide sufficient grip, which could lead to dangerous situations while working at heights. Thus, maintaining this minimum length is crucial for the safety of linemen during climbing operations.
