Risk Assessment

Activity/Process Hazard Who/What Affected Existing Controls Pre-Control Risk (S/L/R) New Controls Required Post-Control Risk (S/L/R)
Selection of appropriate road plates Selection of road plates with inadequate load-bearing capacity or incorrect dimensions Vehicles and pedestrians - risk if plates fail under load
• Operatives - injuries during installation
• Underground services/excavations - damage if plates collapse
• Road plates selected with appropriate load-bearing capacity for expected traffic
• Plates sized to extend minimum 300mm beyond excavation edges on all sides
• Thickness determined based on span and anticipated loads
• Selection considers pedestrian and vehicle traffic
• Only plates in good condition used
• Pre-use inspection for structural integrity
5/3/15 (High) • Implement mandatory pre-installation checklist to verify appropriate plate specification
Site Supervisor, before each installation
5/2/10 (High)
Lifting and handling road plates Manual handling injuries during lifting and positioning
• Crush injuries from dropped plates
• Vehicle and mechanical handling risks
Operatives - musculoskeletal injuries, crush injuries, fractures
• Others in vicinity - injuries from falling/shifting plates
• Mechanical lifting devices used for metal road plates
• Plates equipped with lifting points where appropriate
• Lifting operations planned by competent personnel
• Exclusion zones established around lifting operations
• GRP footway plates provided for manual handling where suitable
• Manual handling training provided
• Team lifting for heavier items
• Weight communicated to handlers
• PPE including safety footwear and gloves
4/3/12 (High) • Develop specific risk assessments for different plate installation scenarios
Health & Safety Manager, within 2 months
4/2/8 (Moderate)
Installing road plates over excavations Inadequate support for plates
• Movement of plates under traffic
• Trip hazards from raised edges
• Collapse of excavation sides under load
Road users - injuries if plates move or fail
• Pedestrians - trips on raised edges
• Operatives - injuries from excavation collapse
• Excavation sides verified as stable before installation
• Sufficient bearing area ensured around excavation
• Minimum 300mm bearing on solid ground all sides
• Plates recessed/secured with countersunk bolts where necessary
• Appropriate ramping with bituminous material if not recessed
• Secured against movement using fixings or bituminous seals
• Installations checked/signed off by competent person
• Traffic management during installation/removal
4/3/12 (High) • Implement mandatory inspection of excavation support before plate installation
Site Supervisor
• Provide specialized training on road plate installation

4/2/8 (Moderate)
Using road plates in vehicular areas Loss of vehicle control (skidding)
• Movement of plates under traffic
• Noise disruption from loose plates
• Vehicle damage from raised edges
Road users - injuries/fatalities in accidents
• Vehicles - damage from raised edges or movement
• Local residents - noise disturbance
• Road plates with appropriate skid resistance selected
• Plates secured against movement with fixings or bedding
• Warning signs placed in advance of plated areas
• Speed restrictions implemented where appropriate
• Regular monitoring and maintenance
• Plates recessed flush where possible
• Anti-skid coatings applied where necessary
• Noise-dampening materials used
• Edge transitions designed to minimize impact
5/3/15 (High) • Establish mandatory daily monitoring program for plates in high-traffic areas
Site Supervisor
• Develop specific traffic management plans for different scenarios
Traffic Management Specialist
5/2/10 (High)
Using footway plates for pedestrian areas Trip hazards from plate edges
• Slipping hazards (especially when wet)
• Inadequate support for mobility devices
Pedestrians (especially elderly, visually impaired, disabled) - injuries from trips and falls
• Wheelchair/mobility scooter users - difficulty crossing or accidents
• Footway plates with slip-resistant surfaces used
• Edges ramped or chamfered to minimize trips
• Warning signs placed where necessary
• Plates secured to prevent movement or lifting
• Appropriate thickness to prevent flexing
• Regular inspections to ensure correct positioning
• Plates kept clean for slip resistance
• Consideration for disabled users
• Alternative routes provided where possible
3/4/12 (High) • Provide regular cleaning of footway plates in high-traffic areas
Site Supervisor
3/2/6 (Moderate)
Inspecting and maintaining road plates Failure to identify damaged/deteriorated plates
• Inadequate monitoring of position and security
• Failure to respond to public concerns
All road users and pedestrians - risk from poorly maintained plates
• Company reputation - damage from perceived negligence
• Regular inspections conducted while in use
• Damaged/deformed/worn plates removed from service
• Maintenance records kept
• Public concerns promptly investigated
• Regular cleaning to maintain skid resistance
• Anti-skid coatings reapplied when worn
• Securing mechanisms checked during inspections
• More frequent inspections in adverse weather
4/3/12 (High) • Establish maintenance program including regular refurbishment
SLT
• Consider implementing QR codes linking to inspection database

No risk score provided
Removal of road plates Premature removal leaving unprotected excavations
• Manual handling injuries during removal
• Damage to road surface/excavation
• Traffic obstruction during removal
Operatives - musculoskeletal injuries
• Road users - risk from traffic disruption
• Public - risk from inadequately protected excavations
• Plates only removed when excavations ready for immediate backfill
• Mechanical lifting devices used for metal plates
• Traffic management in place during removal
• Temporary barriers immediately placed when plates removed
• Excavations backfilled promptly after removal
• Removal planned to minimize disruption
• Plates inspected for damage after removal
• Road surfaces checked and repaired if necessary
4/3/12 (High) • Develop specific risk assessment for plate removal operations
HSQE
• Provide additional training on safe removal techniques

4/2/8 (Moderate)
Using road plates in adverse weather Increased slip hazards in wet/icy/snowy conditions
• Reduced excavation stability during heavy rain
• Changes in ground conditions affecting support
Road users and pedestrians - increased accident risk
• Operatives - risk from excavation instability
• Enhanced skid resistance plates used in wet/icy areas
• Additional warning signs during adverse weather
• Increased inspections during/after weather events
• De-icing materials applied during freezing conditions
• Drainage considered to prevent water accumulation
• Weather forecasts monitored
• Excavations inspected for stability after heavy rain
4/4/16 (High) • Consider alternative solutions to road plates for long-term excavations during winter
