Plan Every Task Before Work Begins
One of the biggest safety mistakes is beginning work before completing a proper risk assessment.
Before anyone leaves the ground, consider:
- What work needs completing?
- How long will it take?
- What equipment is required?
- Who will carry out the work?
- Are there overhead hazards?
- Are there pedestrians nearby?
- Can the task be completed another way?
- What rescue plan is in place?
Planning significantly reduces unexpected problems once work begins.
Carry Out a Thorough Risk Assessment
Every construction project is different.
A comprehensive risk assessment should identify:
| Assessment Area | Questions to Ask |
|---|---|
| Ground conditions | Is the surface stable? |
| Weather | Is it safe to work today? |
| Traffic | Are vehicles operating nearby? |
| Overhead cables | Are minimum clearances maintained? |
| Falling objects | How will debris be controlled? |
| Emergency access | Can emergency services reach the site? |
| Equipment suitability | Is the chosen platform appropriate? |
Risk assessments should be updated whenever site conditions change.
Choose the Correct Access Equipment
One of the most important safety decisions involves selecting suitable equipment.
Different jobs require different solutions.
Common Access Equipment
| Equipment | Best Used For |
|---|---|
| Scissor lifts | Vertical indoor work |
| Boom lifts | Reaching obstacles |
| Articulating booms | Restricted access areas |
| Telescopic booms | Long horizontal outreach |
| Spider lifts | Confined or delicate ground |
| Truck-mounted platforms | Highway maintenance |
| Vertical lifts | Warehouses and retail units |
Hiring professional access equipment from specialists such as Access Hire UK ensures machines are maintained, inspected and suitable for demanding construction environments.
Never Use Equipment Beyond Its Limits
Every access platform has:
- Maximum working height
- Safe working load
- Platform capacity
- Outreach limits
- Wind restrictions
Ignoring these limits creates unnecessary risks.
Common mistakes include:
- Carrying excessive materials
- Allowing too many workers onto one platform
- Overreaching instead of repositioning the machine
- Using the machine on unsuitable ground
Manufacturers specify these limits for good reason.
Inspect Equipment Before Every Shift
Daily inspections are essential.
Checks should include:
| Inspection Item | Why It Matters |
|---|---|
| Tyres or tracks | Stability |
| Hydraulic leaks | Safe operation |
| Emergency lowering system | Rescue capability |
| Controls | Reliable movement |

Maintaining three points of contact reduces slips while climbing into or out of platforms.
Avoid Overreaching
One of the most common causes of falls is reaching too far.
Instead:
- Lower the platform
- Reposition the machine
- Raise it again safely
Although repositioning takes longer, it dramatically improves safety.
Keep Platforms Organised
Messy platforms create trip hazards.
Good housekeeping includes:
| Good Practice | Benefit |
|---|---|
| Store tools securely | Prevents trips |
| Remove waste regularly | Cleaner workspace |
| Secure loose materials | Stops falling objects |
| Avoid clutter | Easier movement |
| Keep exits clear | Faster evacuation |
Simple organisation improves both productivity and safety.
Protect Workers Below
Working at height affects everyone on site.
Safety measures include:
- Exclusion zones
- Barrier systems

Even small tools can cause serious injuries when dropped from significant heights.
Understand Weather Conditions
Weather has a major impact on safe working.
Conditions requiring additional caution include:
- Strong winds
- Heavy rain
- Snow
- Ice
- Lightning
- Dense fog
High winds are particularly dangerous for boom lifts because of their increased surface exposure.
If conditions deteriorate, work should stop until it is safe to continue.
Monitor Ground Conditions
Access platforms rely on stable foundations.
Before positioning equipment, check for:
| Ground Hazard | Possible Issue |
|---|---|
| Soft soil | Machine sinking |
| Underground services | Ground collapse |

- Recent incidents
- Equipment updates
- Manual handling
- Falling object prevention
- Site-specific hazards
Short, regular discussions help maintain safety awareness.
Inspect Access Routes
Workers often focus on the platform itself while overlooking how they reach it.
Safe access routes should be:
- Clear of debris
- Well lit
- Free from trip hazards
- Protected from vehicle movements
- Clearly marked
Safe access begins before anyone leaves the ground.
Avoid Working Alone
Where practical, workers operating at height should not work in complete isolation.
Having colleagues nearby means:

Choosing the correct machine improves both safety and productivity.
Secure Materials Before Lifting
Loose materials become dangerous when elevated.
Workers should:
- Secure loads
- Avoid stacking materials too high
- Keep heavy items low within the platform
- Use tool storage where provided
This reduces the chance of falling objects during movement.
Keep Pedestrians Safe
Construction sites often remain close to occupied buildings or public areas.
Additional precautions include:
- Temporary fencing
- Warning signs
- Banksmen
- Covered walkways where appropriate
- Controlled delivery zones
Protecting the public is just as important as protecting workers.
Budget for Safety Rather Than Minimum Cost
