Scaffold Safety: essential answers
These answers summarize this guide; they do not replace a work permit, legal compliance decision or site-specific risk assessment.
What does this activity involve?
Scaffolds provide temporary access and working platforms but can create severe fall, collapse and falling-object hazards when incorrectly erected, modified or used. Scaffolds should be designed, erected, altered and dismantled by competent persons, inspected before use and maintained in a safe condition throughout the work.
What are the main hazards?
• Falls from open sides, ends or incomplete platforms
• Scaffold collapse caused by poor foundations, missing ties or overloading
• Falling tools, materials or scaffold components
• Unsafe or obstructed access
See the full hazard list below.
What are the essential controls?
• Ensure the scaffold is designed, erected, altered and dismantled by trained and competent persons.
• Provide stable foundations using suitable base plates, sole boards and level supporting surfaces.
• Install all required ties, braces and stabilizers in accordance with the scaffold design.
• Fully deck working platforms and control gaps between boards and structural members.
The full control measures are listed below.
What should be checked before work?
✓ The scaffold has been inspected by a competent person
✓ A valid scaffold-status tag is displayed
✓ Foundations, base plates and sole boards are stable
✓ Ties, braces and stabilizers are installed
✓ Platforms are fully decked and boards are secured
✓ Top rails, midrails and toe boards are complete

Scaffolds provide temporary access and working platforms but can create severe fall, collapse and falling-object hazards when incorrectly erected, modified or used. Scaffolds should be designed, erected, altered and dismantled by competent persons, inspected before use and maintained in a safe condition throughout the work.
Main Hazards
• Falls from open sides, ends or incomplete platforms
• Scaffold collapse caused by poor foundations, missing ties or overloading
• Falling tools, materials or scaffold components
• Unsafe or obstructed access
• Missing guardrails, midrails or toe boards
• Platform gaps, loose boards or insufficient decking
• Contact with overhead electrical lines
• Unauthorized alteration or removal of scaffold components
• Adverse weather, high winds or slippery platforms
Required PPE
✓Safety helmet with secured chin strap where required
✓Safety footwear with slip-resistant soles
✓Suitable work gloves
✓High-visibility clothing
✓Full-body harness and approved fall-arrest system when collective protection is incomplete or required by the assessment
✓Eye protection where work creates flying particles
Essential Controls
1Ensure the scaffold is designed, erected, altered and dismantled by trained and competent persons.
2Provide stable foundations using suitable base plates, sole boards and level supporting surfaces.
3Install all required ties, braces and stabilizers in accordance with the scaffold design.
4Fully deck working platforms and control gaps between boards and structural members.
5Provide complete top rails, midrails and toe boards on exposed sides and ends.
6Provide safe access using secured ladders, stair towers or purpose-designed access systems.
7Display a clear scaffold-status tag and prevent use when the scaffold is incomplete or unsafe.
8Inspect the scaffold before first use, after alteration, after severe weather and at required intervals.
9Keep platforms free from loose materials, waste, ice, oil and trip hazards.
10Respect the scaffold load rating and distribute materials evenly.
11Maintain safe clearance from overhead electrical lines.
12Prevent unauthorized removal or movement of guardrails, boards, ties and other components.
Common Mistakes
×Using a scaffold before inspection or without a valid status tag
×Climbing scaffold frames instead of using designated access
×Working from incomplete or partially decked platforms
×Removing guardrails or boards to create temporary access
×Overloading platforms with materials and equipment
×Leaving loose tools or materials near platform edges
×Using damaged, bent or incompatible scaffold components
×Moving a mobile scaffold while workers remain on the platform
×Continuing work during high winds or severe weather
Pre-use Scaffold Checklist
✓The scaffold has been inspected by a competent person
✓A valid scaffold-status tag is displayed
✓Foundations, base plates and sole boards are stable
✓Ties, braces and stabilizers are installed
✓Platforms are fully decked and boards are secured
✓Top rails, midrails and toe boards are complete
✓Safe and unobstructed access is available
✓The scaffold is free from visible damage or unauthorized alteration
✓Platforms are clean and free from loose materials
✓The intended load is within the scaffold capacity
✓Electrical-line clearance is adequate
✓Weather conditions are suitable for safe use
Unsafe Scaffold and Emergency Response
Stop work immediately if the scaffold moves, leans, settles, becomes damaged, loses ties or guardrails, or shows any sign of instability. Evacuate the platform using the safest available route, isolate the area below and prevent further use. Do not attempt unauthorized repairs. A competent scaffold person must inspect the structure and approve any corrective action before the scaffold is returned to service.
