Is Scaffolding Dangerous?

The short answer is: scaffolding can be dangerous if proper safety measures aren’t followed. Working at height always carries risks, and scaffolding adds another layer of complexity.

According to the Health and Safety Executive (HSE), falls from height remain one of the biggest causes of workplace fatalities and major injuries in the UK construction industry. In fact, recent statistics show that falls from height account for nearly 30% of all fatal injuries to workers, with many of these incidents involving scaffolding.

Here are some statistics to put things into perspective:

50 people died last year in the UK due to falls from height
Over 4,000 workers suffer serious injuries from falls annually
Approximately 15% of all reported construction accidents involve scaffolding

These numbers highlight why strict safety protocols aren’t just recommendations — they’re essential life-saving measures. When you’re working several metres above ground level, even small mistakes can have huge consequences.

This is precisely why it’s crucial to recruit a highly trained and properly insured scaffolding team, like Merlin Scaffolding, for your project. Professional scaffolders undergo rigorous training and follow strict safety guidelines to minimise risks. They understand the complexity of scaffold structures and know how to erect, maintain, and dismantle them safely.

Erecting Scaffolding

The assembly phase is when many scaffolding accidents occur. Here are the key hazards associated with erecting scaffolding and how to control them:

Hazard: Unstable Ground

Scaffolding erected on uneven or soft ground can shift, tilt, or collapse entirely.
Control Measures:

Conduct thorough ground assessments before beginning assembly
Use base plates and sole boards to distribute weight evenly
Ensure adequate drainage to prevent ground softening

Hazard: Structural Weakness

Poor design or substandard components can lead to catastrophic failure.
Control Measures:

Always use scaffolding components that meet British Standards (BS EN 12810-1)
Follow manufacturer guidelines regarding load capacity and set up
Use a tagging system to identify and remove damaged components
Have qualified engineers review complex or unusual scaffold designs

Hazard: Falls During Assembly

Workers are at particular risk when erecting the scaffold before all guardrails are in place.
Control Measures:

Use proper personal fall arrest systems during assembly
Employ the ‘advanced guardrail’ system where temporary guardrails are installed from the level below
Establish clear assembly procedures with safety checkpoints
Never allow workers to climb on scaffold components not designed for climbing

Overloaded Scaffolding

One of the most common causes of scaffold collapse is exceeding the maximum load capacity. Here’s how to address this serious hazard:

Hazard: Excessive Weight

Scaffolding that holds more weight than it was designed for is at risk of collapsing.
Control Measures:

Clearly mark load limits on scaffold structures
Train workers to understand and respect load limits
Distribute weight evenly across the scaffold platform
Consider the combined weight of workers, tools, and materials
Conduct regular inspections to ensure limits aren’t exceeded

Hazard: Dynamic Loads

Activities like jumping, dropping heavy objects, or using powerful tools can create sudden forces that exceed the scaffold’s weight limit.
Control Measures:

Train workers to avoid creating sudden impacts on scaffold platforms
Provide separate structures for activities that create vibration or impact
Use shock-absorbing mats when necessary
Implement strict policies against horseplay on scaffolding

Hazard: Material Storage Issues

Failure to store materials properly can create dangerous imbalances and trip hazards.
Control Measures:

Create dedicated material storage areas away from scaffold edges
Never allow materials to accumulate on scaffolding platforms
Establish clear protocols for material delivery and removal
Consider using material hoists for heavier items

Scaffolding Weather Protection

Adverse weather conditions are among the main hazards associated with scaffolding. Here’s how to control these environmental hazards:

Hazard: High Winds

Strong winds can destabilise scaffolding and create dangerous working conditions.
Control Measures:

Follow wind speed guidelines (typically work should stop when wind speeds exceed 23mph)
Use weather monitoring systems on site
Secure or remove loose materials before high winds arrive
Consider wind loads during the design phase and use ties accordingly
Install wind shields on exposed scaffolding where appropriate

Hazard: Rain and Wet Conditions

Wet conditions increase slip hazards and can affect ground stability.
Control Measures:

Use slip-resistant platform materials
Ensure proper drainage systems are built into scaffold designs
Cover materials that shouldn’t get wet
Provide workers with appropriate footwear
Implement regular inspections after heavy rainfall

Hazard: Extreme Temperatures

Both hot and cold weather can create additional risks.
Control Measures:

In hot weather, provide shade and schedule frequent breaks
In cold conditions, clear ice and snow promptly
Adjust work schedules to avoid the most extreme weather periods
Consider how temperature affects material properties (expansion/contraction)

Hazard: Lightning

Metal scaffolding can attract lightning strikes.
Control Measures:

Cease work and evacuate scaffolding during thunderstorms
Use lightning detection systems on larger sites
Establish clear emergency procedures for severe weather events
Consider proper grounding for very tall scaffold structures

Electrical Hazards

When scaffolding interacts with electrical systems, the risks can be particularly severe. Here’s how to manage these hazards:

Hazard: Overhead Power Lines

When metal scaffolding comes in contact with power lines, workers are at risk of electrocution.
Control Measures:

Conduct thorough site surveys to identify all overhead lines
Maintain safe distances (typically at least 3 metres from power lines)
Use non-conductive materials for screens and barriers where proximity is unavoidable
Consult with utility companies about de-energising lines during work if necessary
Consider scaffold design to maintain clearance from power sources

Hazard: Electrical Equipment on Scaffolding

Power tools and lighting systems create additional electrical risks on scaffolding.
Control Measures:

Use low-voltage systems where possible
Implement proper cable management to prevent trips and damage
Require RCD (residual current device) protection for all electrical equipment
Schedule regular testing of all electrical equipment
Train workers on electrical safety specific to scaffolding environments

Hazard: Wet Conditions Combined with Electricity

Water dramatically increases electrical hazards.
Control Measures:

Use only weatherproof electrical fittings rated for outdoor use
Inspect all connections before use, especially after rain
Implement strict procedures for powering down systems during wet weather
Provide proper storage for electrical equipment when not in use

Employee Training

Perhaps the most important control measure for scaffold safety is comprehensive employee training. Well-trained workers can identify and respond to hazards before they lead to accidents.

Essential Training Elements

All scaffolding workers should receive training in:

Scaffold classification and types
Load calculations and weight distribution
Assembly and dismantling procedures
Fall protection systems
Hazard identification
Emergency protocols
Equipment inspection
Weather safety
Proper use of personal protective equipment (PPE)

Ongoing Education

Scaffold safety isn’t a one-time lesson. The most effective training programmes include:

Regular refresher courses
Updates on new safety regulations and equipment
Toolbox talks specific to current projects
Incident reviews to learn from near-misses
Practical exercises and simulations
