Scaffolding Safety
The Problem
Falls from scaffolding are one of the leading causes of injuries and fatalities in the construction industry. Improper setup, inadequate inspections, and unsafe practices are often the root causes of these incidents. Today, we’ll discuss scaffolding safety—how to identify hazards, follow proper procedures, and prevent accidents on the job site.
Identify the Hazards
- Falls: The most common hazard, caused by missing guardrails, unstable planks, or lack of fall protection.
- Collapse: Scaffolds that are improperly assembled or overloaded can collapse, endangering workers.
- Falling Objects: Tools or materials falling from scaffolds can injure people working below.
- Electrical Hazards: Scaffolds placed too close to power lines can result in electrocution.
Safety Practices and Preventative Measures
Scaffold Setup and Stability
- Ensure scaffolds are erected on stable, level ground with base plates and sole boards.
- Use proper bracing and secure scaffolds to the structure as per manufacturer and engineer specifications.
Load Capacity
- Never exceed the working load limit of a scaffold, including the weight of workers, tools, and materials.
- Distribute loads evenly across the platform to reduce the risk of tipping.
Guardrails and Fall Protection
- Install guardrails, mid-rails, and toe boards on all open sides of platforms 2 metres or higher, or lower where there is a risk of injury.
- Use a personal fall arrest system (harness and lanyard) if guardrails cannot be used and the risk of a fall exists.
Access and Egress
- Use ladders, stair towers, or other safe means of access—never climb scaffold frames.
- Keep access routes clear of tools and debris.
Daily Inspections
- A competent person must inspect scaffolds before each shift and after any alterations or severe weather.
- Check for damaged planks, loose connections, or missing guardrails.
Working Near Power Lines
- Maintain safe approach distances as required by WorkSafe NZ—at least 4 metres unless otherwise authorised.
- Use insulated materials and work with the utility provider if scaffolding must be placed closer.
Falling Object Protection
- Use toe boards, mesh, or debris netting to stop objects falling from platforms.
- Keep tools and materials organised and secured.
Real-Life Case or Scenario
A worker was seriously injured when a scaffold collapsed due to overloading and lack of proper bracing. It had not been tied to the structure, and too much material had been stored on the platform. This incident could have been avoided by following the correct load limits, securing the scaffold, and conducting a proper inspection.
Employee Responsibilities
- Inspect scaffolds before use and report any defects or hazards.
- Follow correct loading limits and never overload platforms.
- Use only designated access points and wear fall protection when required.
- Keep tools secured and avoid throwing or dropping materials from height.
Employer Responsibilities
- Provide scaffolds that meet WorkSafe NZ standards.
- Ensure all scaffolds are erected, altered, and dismantled by competent persons.
- Deliver training on scaffolding safety and fall protection.
- Promptly correct any reported hazards.
Discussion & Questions
- "What common hazards have you noticed with scaffolding on this job site?"
- "Does anyone have an example of a scaffolding-related incident and how it was resolved?"
Commitment/Action Plan
Let’s commit to inspecting scaffolds before every use, following weight limits, and using fall protection when needed. Starting today, make scaffold safety a part of your daily routine.
Wrap-Up
Scaffolding safety is not just about compliance—it’s about making sure we all go home safely. By inspecting scaffolds, following safe practices, and using the right equipment, we can prevent serious injuries and fatalities. Thanks for staying focused on safety.
Standards Overview
WorkSafe New Zealand requires that:
- All scaffolding be erected, altered, and dismantled by competent persons.
- Fall protection be used for platforms 2 metres or higher (or less where a fall risk exists).
- Scaffolds meet the design and construction requirements of AS/NZS 1576 and the Health and Safety at Work Act 2015.
- Daily inspections be carried out by a competent person.
- Safe working loads are clearly marked and not exceeded.
