What is required for ladders used at construction sites to ensure safety?

Ladders used at construction sites must be kept free from any oil or grease to ensure the safety of workers utilizing them. A clean, dry ladder surface promotes better traction and reduces the risk of slip-related accidents, which can lead to serious injuries. The presence of substances like oil or grease can create hazardous conditions, making it difficult for workers to maintain their footing while climbing or descending the ladder.

While there are other safety standards and practices related to ladder use, such as the requirement for ladders to extend a certain distance above a support surface or regular inspections, the need to keep ladders clean is a fundamental aspect of ladder safety that directly impacts the immediate safety of workers at the site.
