Write a risk assessment for Write a risk assessment and a method statement for infrastructure

A suitable RAMS for infrastructure works should begin with a task-by-task risk assessment and method statement covering the sequence of work, hazards, persons at risk, initial risk rating, controls, residual risk, supervision, competence, permits, emergency arrangements, and inspection requirements. The risk assessment should identify each job or task, the hazards, where they are located, the likelihood of injury, the severity of potential injury, and the PPE needed. A practical approach is to use a job hazard analysis that breaks the work into steps and records hazard type, hazard source, body parts at risk, severity, probability, risk code, and control method. [7] [2] [6]

For risk evaluation, use a severity-versus-probability matrix and assign a risk code to each task step. High-risk activities must not proceed until controls are implemented; medium-risk activities require prompt control measures; low-risk activities may proceed if no other mandatory safeguards are required. This is especially important for excavation, lifting, live traffic interfaces, underground services, and plant movement, where the potential for fatal or severe injury is significant. [1] [1] [1]

Typical hazard identification for infrastructure works should include:

• Underground and overhead services, including electric, gas, water, telecoms, and confined utility corridors
• Excavation collapse, falls into excavations, inundation, contaminated ground, and striking buried services
• Plant and vehicle movement, reversing, blind spots, pedestrian interface, and rollover
• Lifting operations, suspended loads, crane radius intrusion, unstable ground, and rigging failure
• Manual handling, hand-arm vibration, noise, dust, silica, fumes, and hazardous substances
• Work at height, falling objects, unstable edges, and access/egress hazards
• Public protection risks, including adjacent roads, footpaths, occupied premises, and third-party access
• Adverse weather, poor visibility, fatigue, lone working, and emergency access constraints

[6] [7] Task-specific controls should follow the hierarchy of controls. First eliminate the hazard where possible, then use engineering controls, work practices, and administrative controls, with PPE as the last layer. The RAMS should clearly state the control method for each hazard and stop the work if the residual risk remains unacceptable. [3] [2] [3]

A safe system of work for infrastructure activities should include:

• Pre-start planning, utility searches, drawings review, permits, and site-specific briefing
• Competent supervision and trained operators, slingers, signallers, banksmen, and excavator operators
• Defined work sequence, exclusion zones, and communication arrangements
• Inspection of plant, lifting gear, access equipment, and excavation supports before use
• Segregation of pedestrians and vehicles, controlled access points, and public protection barriers
• Permit-to-dig, permit-to-lift, hot-work or isolation permits where applicable
• Monitoring for changing ground, weather, traffic, and service conditions, with authority to stop work
• Daily briefings, toolbox talks, and review of RAMS when scope or conditions change

[11] [11] PPE requirements for infrastructure works should be selected from the hazard assessment and commonly include:

• Head protection where there is risk from falling objects, low overhead obstructions, or electrical exposure
• Eye and face protection for dust, flying particles, cutting, grinding, breaking, drilling, and chemical splash risks
• High-visibility torso protection for plant and traffic interface areas
• Hand protection matched to the hazard, such as general work gloves, cut-resistant gloves, chemical-resistant gloves, or insulated gloves
• Foot protection such as steel toe footwear, puncture-resistant soles, slip-resistant soles, or chemical-resistant boots
• Hearing protection where noise exposure reaches or exceeds action levels
• Fall protection where there are unguarded edges or work above lower levels
• Respiratory protection where dust, silica, fumes, or other airborne contaminants cannot be adequately controlled by other means

[8] [16] [14] [15] [17] [9] [10] [6] For excavation works, the RAMS should require service detection and confirmation before breaking ground, a permit-to-dig system, safe excavation support or battering/benching as appropriate, spoil and plant kept back from edges, safe access and egress, inspection by a competent person, and controls for water ingress, contaminated ground, and atmospheric hazards where relevant. No one should enter an unsupported excavation where collapse is possible, and excavator operations should be controlled with exclusion zones and a trained banksman where visibility is restricted.

For lifting operations, the RAMS should define the lift plan, load weight, radius, crane or lifting appliance capacity, ground bearing capacity, rigging arrangement, exclusion zone, communication method, weather limits, and competent personnel. Lifting accessories should be inspected before use, suspended loads must never pass over people, and the area should be controlled to prevent unauthorized entry. Complex or high-risk lifts should be planned and supervised by an appointed competent person.

For plant and equipment, only suitable and inspected equipment should be used, with operators trained and authorized for the specific machine. Pre-use checks should cover brakes, steering, alarms, lights, guards, attachments, tires or tracks, leaks, and emergency devices. Defective plant should be taken out of service. Reversing should be minimized, and where unavoidable it should be controlled by segregation, cameras or alarms, and a banksman when needed.

Traffic management should be documented in the RAMS and site traffic plan. It should include delivery routes, one-way systems where possible, speed limits, pedestrian walkways, crossing points, signage, barriers, lighting, reversing controls, and arrangements for interface with the public highway. Where works affect live roads or footpaths, use approved temporary traffic management layouts, maintain emergency access, and protect pedestrians with clear segregated routes.

Site safety arrangements should include induction, welfare, housekeeping, lighting, secure storage, environmental controls, first aid, fire points, spill response, and clear reporting lines. Regular inspections are necessary to confirm that controls remain effective and to identify new hazards when equipment, materials, processes, or locations change. [5] [5]

Emergency procedures in the RAMS should cover excavation collapse, service strike, fire, medical emergency, plant collision, lifting incident, hazardous substance exposure, and severe weather. The document should state emergency contacts, site address and access points, rescue arrangements, isolation procedures for utilities and plant, first-aid provision, spill containment, and evacuation or muster arrangements. Workers should be briefed on who raises the alarm, who contacts emergency services, and who controls the scene until help arrives.

In terms of compliance and documentation, the RAMS package should include the risk assessment, method statement, PPE hazard assessment, permits, inspection records, plant certifications, lifting accessory records, training and competence records, induction records, emergency arrangements, and evidence of communication to the workforce. PPE selection must be communicated to affected employees, fitted correctly, used when exposed to hazards, and maintained in safe condition. [12] [4] [13]

A concise RAMS structure for infrastructure works is: scope of works; responsibilities; competence requirements; references and permits; plant, tools, and materials; sequence of operations; hazard identification and risk ratings; control measures by task; PPE; traffic and pedestrian management; excavation controls; lifting controls; environmental controls; emergency procedures; monitoring, inspection, and review; and workforce briefing/sign-off. The assessment should be certified and kept under review whenever the job changes, new equipment or processes are introduced, an accident occurs, or site conditions materially change. [5] [11] [3]
