Working at Height Safety in Construction

Falls from height remain one of the leading causes of serious injury and fatality in the construction industry. Understanding the risks and applying effective control measures is essential to prevent accidents and protect lives.

What is Working at Height?

Working at height includes any task where a person could fall and suffer injury. This is not limited to obvious high-level work such as scaffolding or roofs. It also includes:

• Ladders and step ladders
• Working platforms and podium steps
• Edges and open sides
• Fragile surfaces
• Ground-level openings such as trenches or shafts

Any situation where a fall is possible must be treated as a working at height risk.

The Hierarchy of Control for Working at Height

Avoid Working at Height Where Possible

The first and most important step is to avoid working at height altogether. If a task can be completed safely from the ground using:

• Long-reach tools
• Mechanical equipment
• Better planning or alternative methods

this should always be the preferred option.

Plan Work at Height Properly

If working at height cannot be avoided, it must be carefully planned. This includes selecting the safest method and ensuring that suitable equipment is available and used correctly.

Examples of appropriate equipment include:

• Scaffolding
• Mobile Elevating Work Platforms (MEWPs)
• Podium steps
• Properly secured ladders

Good planning helps prevent rushed decisions and unsafe practices.

Assessing the Work Area

Before starting any task, the area must be thoroughly assessed for hazards, including:

• Unstable or uneven ground
• Weather conditions such as wind or rain
• Overhead obstructions
• Fragile roofs or surfaces

A safe working platform must be stable, level and strong enough to support workers, tools and materials.

Using the Right Equipment Safely

All equipment used for working at height must be suitable, well-maintained and used correctly.

• Scaffolding must be erected, inspected and signed off by a competent person
• Ladders should only be used for short-duration, low-risk tasks and must be properly secured
• MEWPs must only be operated by trained and certified workers

Good Housekeeping and Safe Platforms

Housekeeping plays a key role in preventing falls. Work platforms must be kept tidy and free from hazards.

Risks can arise from:

• Loose materials
• Tools left near edges
• Debris or cluttered walkways

Maintaining a clean and organised workspace significantly reduces the risk of trips and falls.

Edge Protection and Fall Prevention

Where there is a risk of falling, collective protection measures must be in place, including:

• Guardrails
• Toe boards
• Barriers and edge protection

If these measures cannot fully eliminate the risk, fall arrest or fall restraint systems may be required.

These systems must only be used by trained and competent individuals.

Conclusion

Working at height is a major risk in construction, but it can be managed effectively with the right approach. By avoiding unnecessary work at height, planning tasks carefully, using suitable equipment and maintaining good housekeeping, organisations can significantly reduce the risk of falls and keep workers safe.
