Health and Safety Executive Management of contractors: short duration & fragile roof work Liz Standen HM Inspector of Health and Safety
KEY ELEMENTS OF MANAGEMENT SYSTEM
Outline of WAH Regulations • • Requirements for: - • • • Competence (Reg 5) • • Requirements for work equipment (Reg 8) Organisation, planning & supervision (Reg 4) Avoidance of risk from WAH (Reg 6) Selection and use of work equipment for WAH (Reg 7) Risk assessment approach
Selection of equipment – regulation 7 • • Choice of work equipment must take account of: • Access and egress and the distance to be negotiated • • Distance and consequences of a fall Working conditions and the risks to persons safety Duration and frequency of use Ease of rescue/evacuation Risk of use, installation and removal of equipment
Safe means of access onto roof • Existing means, internal/external staircase or ladder and roof access hatches • • • General access scaffolds Stair towers Fixed or mobile scaffold towers Mobile access equipment Ladders
Preventing falls
Verge edge protection
Fall mitigation
Short duration work • Tasks measured in minutes rather than hours • Includes inspection, replacing a few tiles, adjusting TV aerial • May not be RP to install edge protection or independent scaffold • Precautions depend on overall assessment of risk
Minimum requirements for short duration work on roofs • Safe means of access to roof level (secured ladder to eaves as a minimum) • Safe means of working on the roof e. g. : – On a sloping roof a properly constructed and supported roof ladder – On a flat roof a fall restraint harness secured to suitable anchor points – Fall arrest as last resort – importance of rescue plan – MEWPS – particularly appropriate for shortduration minor work
Demarcation of access routes and work areas • • • For short-duration limited work on sections of flat roof where edge protection not reasonably practicable Simple form of continuous physical barrier which identifies work area and access routes – “safe area” Barrier must be at least 2 m from edge of roof, leading edges and fragile materials No unprotected holes, breaks or fragile materials within “safe are” unless suitably protected Barriers should be durable and immediately obvious to all –bunting, tape, markings at foot level not acceptable Use of demarcation barrier requires high level of supervision and discipline
The things we see when out and about!
Fragile roofs • • Single layer roof lights • Non-reinforced fibre cement sheets • Falls through fragile roofs account for 22% of all fatal falls Corroded metal sheets • Glass (including wired glass) • Rotted chipboard An average of 7 deaths a year Not just construction – maintenance repair and cleaning
Fragile roofs • Roof materials and fixings will degrade overtime (erosion, weather damage, UV, etc) and result in fragility • All roofs should be treated as fragile until a competent person has confirmed they are not
Fragile roof hierarchy • Work from underneath using a suitable work platform • Work from a MEWP basket • Perimeter edge protection and staging/crawling boards which spread load across roof (should span at least two purlins) • Staging should be fitted with guardrails otherwise fall mitigation required (crash-decks, birdcage, nets, soft landing systems, fall arrest)

Key elements of successful contractor management • • Procurement Competence & leadership Planning & selection of equipment Good communication Strong supervision Workforce buy-in Behavioural culture
What it looks like when done effectively What it looks like when it is done badly or not at all. Leaders: -Maintain attention on the significant risks and implementation of adequate controls. -Demonstrate their commitment by their actions, they are aware of the key health and safety issues; -Ensure consultation with the workforce on health and safety. -Challenge unsafe behaviour in a timely way Leaders: -Set no health and safety priorities -Don’t understand the need to maintain oversight. -Do not meet their own organisation’s standards/procedures e. g. wearing correct PPE on site/shop floor. Lack of engagement with health and safety by workers. Health and safety is seen as an add-on, irrelevance or nuisance Poor incident history (accidents, near misses, plant damage or other indicators e. g. poor maintenance, poor housekeeping). Management of health and safety A systematic approach is used to manage health and safety People understand the risks and control measures associated with their work. Contractors adhere to the same standards Appropriate documentation is available: current, organised, relevant People understand their roles and those of others. Performance is measured – to check controls are working and standards are being implemented, and learn from mistakes after things go wrong. Beyond compliance: A formal system (such as BS OHSAS 18001, ISO 9001) is used: has it been externally accredited? Health and safety is integrated into business processes Benchmarking is used to compare performance with others. Supply chains are influenced to improve health and safety. A ‘Wellness’ programme is in place. Management of health and safety Incomplete or missing paperwork. Does not link to actual risks in workplace. Confusion over roles, inaction as no one takes responsibility for health and safety, distrust of management motives. Widespread, routine violations of procedures. No oversight of contractors. Information is not passed on, not understood, or not implemented. Managers are unaware of employee concerns or do not respond appropriately Lessons are never learnt.
Tips for managing contractors • • Use PAS 91 for procurement competence • Clear job spec with benchmarks & penalties for non-conformance • • • Check supervisory competence Get early input from competent CDMC & designer Mechanism for RA review for job revisions Monitor actual site performance Clear communication, roles & responsibilities End of project review with contractor’s director
