What is the maximum permissible length for a single section ladder?

The maximum permissible length for a single section ladder is 20 feet. This design limitation is in place to ensure safety during use, as longer ladders can become unwieldy and more difficult to control when being raised or lowered. A single section ladder that exceeds this length may pose a greater risk of tipping over, collapsing, or causing injury during use due to its increased height and instability.

This 20-foot maximum is typically applied in many safety regulations and guidelines for ladders, prioritizing worker safety while allowing for versatility in various job applications. By keeping the ladder within this length, users can maintain better balance and control, making it easier to access elevated work areas securely.
