What is the minimum height an access ladder should extend above the landing?

The minimum height an access ladder should extend above the landing is 900mm. This height is established to ensure that individuals using the ladder have a secure handhold when transitioning from the ladder to the landing. A ladder that extends 900mm above the landing provides adequate support, allowing users to safely grip onto the landing area while stepping off the ladder, thereby reducing the risk of slips and falls. This requirement is in line with safety regulations that aim to provide safe access and egress for workers, especially in construction and maintenance settings.

Ladders that extend insufficiently above the landing can compromise safety, as users may not have a stable point of contact during dismount. It is essential that safety standards be adhered to in order to maintain a safe working environment. Additionally, standards are often developed based on industry practices and worker safety data, aiming to minimize accidents related to ladder use.
