What Height Classifies as Working at Height?

One of the most common questions we hear during training is:

“What height counts as working at height?”

Many people assume there must be a specific height measurement that determines when work becomes classified as working at height.

In reality, the definition is much broader and focuses on the risk of falling, not the distance from the ground.

In this REAX training video, Andy explains the concept using a simple example to demonstrate how working at height can occur above ground level, below ground level or even at ground level.

The key principle behind working at height regulations is simple:

A task is considered working at height if a person could fall from a distance liable to cause personal injury.

This means there is no specific height threshold where work suddenly becomes classified as working at height.

To explain this concept, consider three simple examples:

• Standing at ground level next to a large hole where a fall could occur
• Climbing a ladder from the bottom of an excavation
• Working on a tower structure above ground level

In each of these situations, there is a risk of falling and being injured, meaning the task falls under working at height safety considerations.

Practical Steps / Key Takeaways

When determining whether work qualifies as working at height, ask the following questions:

• Could a worker fall from their position and be injured?
• Are there open edges, holes or drop-offs nearby?
• Is work being carried out on ladders, platforms or structures?
• Could materials or equipment increase the fall risk?
• Are appropriate control measures in place to prevent a fall?

If a fall risk exists, the activity should be treated as working at height, regardless of the actual height involved.

We emphasise that working at height is about understanding risk, not focusing on a specific measurement.

Many incidents occur during everyday tasks that appear low level but still involve a fall hazard.

By helping organisations recognise these risks early, we can ensure appropriate planning, equipment and training are in place before work begins.

Clear understanding of what qualifies as working at height is an important first step in improving safety across many industries.
