Falls from height are a major cause of construction fatalities. The Work at Height Regulations require employers to plan work, use the right equipment like scaffolds or cherry pickers, and ensure workers are competent to safely complete tasks and prevent falls. Collective fall protection like nets or air bags should be prioritized over personal measures like harnesses. Ladders should only be used for light, short-duration work when no safer option is available. Fragile roofs require special precautions like working from below using a mobile elevating work platform.

- 1. Health and Safety Executive Health and Safety Executive Safe working on or near roofs
- 2. Summary • Why • The law • In practice • Ladders • Golden rules
- 3. WHY • Gravity kills • More fatal accidents in construction caused by falls than anything else • Two biggest classes of fatal falls – are domestic roof level repairs (7 off ladders, 6 other causes) – through fragile roof (5 last year), even more this) Numbers are provisional 2008/9 stats and typical

- 6. The Law Work at Height Regulations 2005 • Apply to all work activities in all industries • Apply to all at work by employees, employers or self employed • Plan work • Use the right equipment • Use competent people PREVENT FALLS, REDUCE INJURY
- 7. The Regulations Hierarchy • AVOID work at height if you can • PREVENT falls by using the proper gear, such as scaffolds or cherry pickers • MINIMISE the chances of being hurt if you fall Applies even to small, quick jobs Doing nothing is dangerous and illegal
- 10. Risk Assessment Examples of what to consider include: • the work activity • equipment to be used • location of the work and any hazards • working environment (weather, lighting) • condition of existing work surfaces • duration of the work • physical capabilities of workers
- 11. Avoid work at height
- 12. Prevent Falls • Use an existing or ‘safe’ place of work where no additional measures are required • Use working platforms with guardrails or powered access platforms • Use a work restraint system (preventing someone getting into a position from which he can fall)
- 14. Minimise the distance and consequences • Collective control measures should always take priority over personal control measures. • Collective measures e.g. airbags, nets etc. are usually passive and require no action by the user • Personal protection measures e.g. fall arrest harnesses are ‘active’ and require the user to do clip on for them to work effectively
- 15. Minimise the risks using collective measures Nets Air bags
- 16. Select the right gear Think about • Where you are going to be working (ground conditions, space, public) • How far you could fall and how likely you are to be injured • How long will the job take and how often will it need to be done • What you need to do to rescue someone should they fall • Can the building or scaffold etc take the weight of the workforce and materials need for the job • Is it the best piece of kit for the job
- 17. Select the right equipment
- 18. Select the right equipment
- 19. Use of ladders Not banned but should only work from a ladder (including step ladder) • when other equipment such as a tower scaffold is not suitable • for light work that takes a few minutes • of the correct type and in good condition • placed on firm level ground and properly secured • and set at the correct length and angle for the job
- 20. Appropriate use of ladders?
- 21. Use work equipment to prevent a fall
- 22. Other things to think about • Prevent tools and materials falling – Throwing materials or debris (bombing) never acceptable • Warn employees about danger areas • You need to make sure that equipment such as scaffolds are checked • After assembly or installation • At suitable intervals or after exceptional circumstances • Scaffold and tower scaffold inspection in each new position and then every 7 days • MEWP on site within previous 7 days
- 23. Fragile Roofs • Sheet materials including asbestos cement or skylights – Will not support weight • Walking the bolts not acceptable • Work from underneath from a mewp wherever possible (special roof fixings available to allow this)
- 24. Golden rules • Plan • Choose right equipment to – Prevent falls – Reduce injury • Competent workers Don’t chance it
