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

A suitable RAMS for infrastructure works should be built around a task-by-task risk assessment, a documented safe system of work, competent supervision, and continuous review as site conditions change. Start with a baseline survey of the workplace, work processes, tasks, and equipment; then break each activity into steps, identify hazards, sources, exposed persons, likelihood, and severity, and assign a risk priority so that high-risk work is stopped until effective controls are in place. Reassess whenever the job changes, new equipment is introduced, an accident occurs, or site conditions materially change. [3] [9] [1]

• Typical infrastructure-work hazards to assess include: excavation collapse, buried/overhead utilities, plant movement, lifting operations, struck-by and caught-between hazards, traffic interface, falls into excavations or from edges, manual handling, noise, dust including respirable silica, vibration, hazardous substances, flooding or water ingress, unstable ground, poor lighting, adverse weather, and public interface.
• For each task step, record the hazard type, hazard source, body parts at risk, severity, probability, risk code, and control method.
• Use the hierarchy of controls first: eliminate the hazard where possible, then engineering controls, work-practice controls, administrative controls, and PPE last.
• Suspend any activity assessed as high risk until the hazard is eliminated or reduced to an acceptable level.

[9] [2] [1] A practical safe system of work for infrastructure projects should include pre-start planning, permits, utility verification, competent operators, exclusion zones, inspection regimes, communication arrangements, and emergency readiness.

• Before work starts: review drawings and utility records, obtain permits, complete site-specific RAMS, brief the workforce, confirm competencies, inspect access/egress, and verify emergency arrangements.
• During work: maintain supervision, segregate pedestrians and plant, enforce exclusion zones, control access to excavations and lifting areas, monitor weather and ground conditions, and stop work if conditions deviate from the RAMS.
• After changes or incidents: review the assessment, update controls, re-brief affected workers, and document the revision.

[5] [10] Task-specific risk controls for common infrastructure activities:

• Excavation and trenching: locate and isolate underground services before breaking ground; use a permit-to-dig; provide suitable support, battering, or trench boxes based on soil and depth; keep spoil and plant back from the edge; provide safe access/egress; inspect excavations at the start of shift and after rain, vibration, or ground disturbance; prevent falls with barriers; control water ingress and atmospheric hazards where relevant.
• Lifting operations: use a lift plan for routine and complex lifts; verify crane/excavator lifting capacity, ground bearing pressure, outrigger support, and certified lifting accessories; appoint competent operator, slinger/signaller, and supervisor; establish exclusion zones; never allow personnel under suspended loads; control wind and visibility limits.
• Plant and equipment: use only inspected and suitable plant; complete pre-use checks; ensure guards, alarms, cameras, lights, and emergency stops function; separate reversing plant from pedestrians; isolate and lock out equipment before maintenance.
• Traffic management: implement a traffic management plan with designated routes, barriers, signage, speed limits, banksmen where needed, delivery controls, and protected pedestrian walkways; coordinate with public-road requirements where works interface with live traffic.
• Temporary works and work at height: verify design and inspection of shoring, edge protection, covers, and access systems; protect openings; use fall prevention before fall arrest.
• Environmental and occupational health controls: suppress dust, manage noise and vibration, control runoff and contamination, store fuels/chemicals safely, and use SDS information for hazardous substances.

[3] [3] [9] Construction health and safety requirements should include competent persons, induction and task briefing, permit-to-work controls, inspections, welfare, housekeeping, incident reporting, and worker involvement in hazard review.

• Provide site induction covering hazards, emergency arrangements, traffic routes, utilities, welfare, and reporting lines.
• Use permits for high-risk activities such as excavation, lifting, hot work, confined spaces, and electrical isolation where applicable.
• Ensure workers are trained, supervised, and fit for task; verify licenses/certificates for plant operators and lifting personnel.
• Maintain good housekeeping, lighting, access routes, and material storage to reduce slips, trips, fire load, and struck-by risks.
• Carry out regular inspections and involve workers in reviewing job steps, hazards, and practical controls.

[10] [4] PPE for infrastructure works should be selected only after higher-order controls are considered, and it must match the hazard, fit the worker, and be maintained in safe condition.

• Typical minimum site PPE: safety helmet, high-visibility clothing, safety footwear, and task-appropriate gloves and eye protection.
• Additional PPE based on assessment: hearing protection, respiratory protection, face shield, cut-resistant gloves, chemical-resistant gloves, fall protection, flotation devices near water, weather protection, and arc-rated/electrical PPE where electrical hazards exist.
• Head protection is needed where there are overhead objects that could fall, exposed low beams, or energized electrical equipment.
• Fall protection is needed where there are unguarded surfaces above a lower level or above dangerous equipment.
• Torso protection may include high-visibility garments, flame-resistant clothing, chemical-resistant coveralls, or insulated clothing depending on the hazard.
• Hand protection should be selected for mechanical, chemical, thermal, or electrical hazards and matched to the specific exposure.

[2] [6] [7] [8] [11] [12] Emergency procedures in the RAMS should cover rescue, first aid, fire, utility strike, trench collapse, plant collision, lifting incident, hazardous substance exposure, severe weather, and evacuation. The document should define alarm methods, emergency contacts, nearest hospital, site access for responders, rescue equipment, spill kits, fire extinguishers, and who is authorized to stop work. For excavations, plan non-entry rescue where possible and never allow unplanned rescue attempts into an unsafe trench or confined space. All incidents, near misses, and significant changes should trigger review of the RAMS and re-briefing. [5] [4]

For compliance, the RAMS should demonstrate that hazards have been assessed, controls selected using the hierarchy of controls, PPE decisions communicated to affected workers, and the assessment reviewed and documented as required by the applicable jurisdiction. The cited documents specifically reference Oregon OSHA and Washington L&I/WAC-based PPE assessment approaches, including certification of the hazard assessment, employee communication, fit, use, and periodic reassessment. For infrastructure works, you should also ensure compliance with the applicable construction, excavation, lifting, traffic-management, utility, environmental, and emergency-planning laws and codes in the country/state where the project is executed.

In practice, a concise RAMS structure for infrastructure works should include: scope of works; sequence of operations; roles and responsibilities; plant, tools, and materials; competency requirements; hazard identification and risk ratings; task-specific controls; permits; PPE; inspection and maintenance requirements; traffic management; lifting and excavation controls; environmental controls; emergency arrangements; and monitoring/review arrangements.
