What is the maximum allowable scaffold plank extension beyond its support?

The maximum allowable scaffold plank extension beyond its support is 300 mm. This limit is in place to ensure safety and stability while working on scaffold systems. Extending planks beyond their support structures can create a risk of tipping or failure, which can lead to falls or accidents.

When scaffold planks are properly supported and extend no more than this specified distance, it helps maintain a balanced load distribution and minimizes the risk of the plank sliding off or failing under weight. This guideline is critical in construction and carpentry work, as it ensures the scaffolding is safe for workers who rely on it to perform their tasks at height.

Adhering to these standards is crucial for preventing incidents on job sites, and it emphasizes the importance of using scaffolds correctly according to established safety regulations.
