Health and Safety Legislation

  • HASAWA 1974 s.2 requires employers to ensure the health, safety and welfare of employees and others affected by their work, so far as is reasonably practicable.

  • HASAWA 1974 s.7 requires employees to take reasonable care of themselves and others, cooperate with safety arrangements and not misuse equipment provided for protection.

  • NRSWA 1991 requires street works to be signed, lit and guarded and reinstated to prescribed standards; undertakers must give notices and work to the prescribed specification.

  • Traffic Management Act 2004 Part 3 places a network management duty on local traffic authorities and enables permit schemes for works on the highway.

  • CDM 2015 applies to construction work including roadworks; a project is notifiable if it exceeds 30 working days with more than 20 workers at once, or 500 person-days.

  • RIDDOR requires reporting of work-related deaths, specified injuries, over-seven-day incapacitation, dangerous occurrences and certain occupational diseases.

  • Management of Health and Safety at Work Regulations 1999 require suitable and sufficient risk assessments, competent assistance and arrangements for serious imminent danger.

  • The hierarchy of control is: eliminate, substitute, reduce by engineering controls, reduce by administrative controls, then use PPE as a last resort.

  • PPE at Work Regulations 1992 require employer-provided PPE to be free of charge; employees must use it and report loss or damage.

Roles and Responsibilities

  • Under CDM 2015 the client has the greatest influence on a project and must make suitable arrangements for managing it, including allocating sufficient time and resources.

  • The principal designer coordinates health and safety during the pre-construction phase; the principal contractor coordinates health and safety during the construction phase.

  • The highway authority manages the road network, the street authority administers street works, and the undertaker carries out works on or under the highway.

  • The works supervisor must ensure signing, lighting and guarding are installed, checked and maintained for the duration of the works.

  • Operatives must follow the safe system of work, use the required PPE, and report defects, near misses and unsafe conditions to the supervisor.

  • A competent person has sufficient training, experience and knowledge and is appointed in writing where legislation requires a formal appointment.

  • NRSWA requires supervisors and operatives to hold the relevant competence card for the work type, with reassessment at intervals set by the scheme.

  • Site induction must be completed before work starts and must cover site hazards, traffic management, PPE rules and emergency arrangements.

  • Any worker can stop work if there is a risk of serious injury; the stop-work decision must be reported and the risk controlled before work restarts.

Quick reference

Personal Protective Equipment and Safe Systems of Work

  • PPE must be provided free at the point of use and selected from the risk assessment; it supplements, but does not replace, engineering and administrative controls.

  • Head protection on roadworks should meet BS EN 397; high-visibility clothing should meet BS EN ISO 20471, minimum class 2, with class 3 where the risk assessment requires.

  • Safety footwear for roadworks should meet BS EN ISO 20345 with toe protection; soles must suit wet, oily or uneven ground.

  • Eye, hand and hearing protection must be task-specific and compatible with other PPE worn by the operative.

  • High-visibility clothing must be worn on site, kept clean, and replaced if its retroreflective performance is degraded.

  • A safe system of work defines the sequence of operations, segregation of people and plant, access, egress and emergency arrangements.

  • A dynamic risk assessment is a continuous check of changing conditions; if conditions change, work stops and the safe system of work is revised.

  • Before entering a site, workers must complete induction and be briefed on the method statement, PPE rules and emergency arrangements.

  • Excavations, confined spaces and live carriageways require specific controls in addition to general PPE.

Quick reference

Signing, Lighting and Guarding of Roadworks

  • Signing, lighting and guarding must be installed before works begin and maintained until the site is safe for traffic and pedestrians.

  • Advance warning signs must be placed on all approaches; the distance from the first sign to the works increases with the speed limit according to the code of practice.

  • Signs must be visible, stable, not obscured by plant or spoil, and removed or covered when not in use.

  • Cones and barriers mark the works and taper traffic away from the closed area; the taper length increases with the speed limit.

  • Obstructions and excavations must be marked with red lamps visible from both directions during darkness or poor visibility.

  • Stop/go boards must be operated by two trained operatives who can see each other or communicate reliably; a single board is not used to control two-way traffic.

  • Portable traffic signals must be positioned so drivers see the signal before the works and cannot see conflicting signals.

  • Pedestrian routes must be signed, lit, barrier-protected and kept free of trip hazards; a footway closure requires an alternative signed route.

  • At the end of a shift the site must be left safe: covers secured, barriers in place, lamps lit and signing checked.

Quick reference

Traffic Management and Site Layout on the Highway

  • Traffic management options include lane closure, contraflow, convoy working, portable signals, give-and-take and road closure.

  • A road closure requires a Temporary Traffic Regulation Order or permit approval; the diversion route must be signed and suitable for the traffic using it.

  • The traffic management plan must cover access, egress, emergency vehicles, pedestrians, cyclists and works vehicle movements.

  • Site layout must separate pedestrians from plant and traffic using barriers, walkways and controlled crossing points.

  • Works vehicles should enter and leave in a forward direction where possible; reversing must be controlled by a banksman.

  • Materials and spoil must be stored clear of carriageway, footway, drains and access points, and must not block sight lines.

  • Temporary speed limits must be shown on approved signs and authorised by the highway authority; they cannot be imposed without approval.

  • Welfare facilities must be provided off the carriageway and located so workers do not cross live traffic unnecessarily.

  • At night the site must be lit so signs, barriers and walking routes are visible without causing glare to drivers.

Quick reference

Excavation, Underground Services and Reinstatement

  • Before excavation, obtain utility plans, carry out a desk study and use a cable avoidance tool and signal generator to locate buried services.

  • Trial holes must be hand-dug to confirm service position and depth; mechanical excavation is not used within the utility's specified safety margin.

  • Excavations must be supported by shoring, trench boxes or safe battering, and the support system must be designed by a competent person.

  • Excavations must be inspected by a competent person at the start of each shift and after rain, vibration or ground movement, with the inspection recorded.

  • Spoil, materials and plant must be kept back from the excavation edge to prevent collapse and falling objects.

  • Excavations must be barriered, covered or fenced; covers must be secure and marked with their load capacity.

  • Access and egress must be by ladders or steps kept clear and secure; workers must not jump into or climb out of trenches.

  • Confined spaces require a permit, gas testing, ventilation, rescue arrangements and a competent person before entry.

  • Reinstatement must follow the specified layers, compaction and materials; temporary reinstatement must be safe for traffic until permanent works are completed.

Plant, Equipment and Working Safely Near Live Carriageways

  • PUWER 1998 requires work equipment to be suitable, maintained, inspected where required and used only by competent people.

  • LOLER 1998 requires lifting equipment and accessories to be thoroughly examined at specified intervals and lifting operations to be planned.

  • Plant operators must hold the correct competence card for the machine and must complete daily pre-use checks.

  • Plant on or near the highway must display flashing amber beacons and be controlled by a banksman when reversing or slewing.

  • A safety zone must separate workers from live traffic; no operative may enter a live lane without approved traffic management.

  • Reversing should be eliminated where possible; where unavoidable, reversing areas must be segregated and controlled.

  • Quick-hitch couplings must be checked and confirmed engaged before lifting or moving attachments.

  • Fuel, oil and chemical spills must be contained with spill kits; contaminated material must be disposed of as hazardous waste.

  • Workers near live carriageways must wear high-visibility clothing and remain behind barriers unless their task requires otherwise.
