Road Cutting and Paving HIRA (Hazard Identification and Risk Assessment)
Road cutting and paving are essential operations in highway construction, infrastructure development, and utility trenching. These activities involve the use of heavy equipment, hot bituminous materials, and manual labor, often in open environments with moving traffic and changing weather conditions.
This makes roadwork inherently hazardous due to risks such as machinery accidents, contact with hot surfaces, dust and fumes, noise exposure, slips, and potential underground utility strikes.
A comprehensive HIRA is vital to control these hazards, ensuring the safety of workers and the public while maintaining productivity and quality.
Objective of Road Cutting and Paving HIRA
- To identify hazards associated with road cutting and paving operations.
- To assess and categorize risks based on severity and likelihood.
- To implement effective control measures (engineering, administrative, and PPE).
- To ensure compliance with traffic management and worker safety standards.
Scope
This HIRA applies to:
- Asphalt and concrete road cutting (manual or mechanical)
- Paving with bitumen, concrete, or other surface materials
- Handling hot mix asphalt and compaction equipment
- Road preparation and leveling
- Temporary traffic diversion and pedestrian safety
- Working around live traffic zones
Step-by-Step HIRA for Road Cutting and Paving
1. Activity Description
Road cutting involves cutting existing pavement using machines or tools to access sub-layers or install utilities. Paving includes laying and compacting new materials (e.g., bitumen or concrete) to build or resurface roadways.
2. Hazard Identification Table
| S. No. | Hazard | Potential Effects | Persons at Risk |
|---|---|---|---|
| 1 | Contact with moving machinery (cutters, rollers) | Crush injuries, amputations | Operators, workers nearby |
| 2 | Exposure to hot bitumen/asphalt | Burns, skin irritation | Paving crew |
| 3 | Dust inhalation from cutting concrete/asphalt | Respiratory illness | Operators, helpers |
| 4 | Noise from road cutters and compactors | Hearing loss | Machine operators |
| 5 | Vibrations from road equipment | Hand-arm vibration syndrome | Equipment operators |
| 6 | Slips on loose gravel, bitumen, or water | Sprains, fractures | All site workers |
| 7 | Working near traffic without barriers | Vehicle collisions, fatality | Crew and pedestrians |
| 8 | Underground utility strikes | Electrocution, explosion, flooding | Cutting team |
| 9 | Manual handling of paving blocks and bags | Back injury, muscle strain | Laborers |
| 10 | Improper PPE or hot weather conditions | Heat stress, dehydration | Entire workforce |
3. Risk Assessment Matrix
Risk Rating = Likelihood (L) × Severity (S)
Scale: 1–5 for both L and S
| Hazard | L | S | Risk Rating | Risk Level |
|---|---|---|---|---|
| Machinery contact | 3 | 5 | 15 | High |
| Bitumen/asphalt burns | 3 | 4 | 12 | High |
| Dust exposure | 4 | 3 | 12 | High |
| Noise | 4 | 2 | 8 | Medium |
| Vibration | 3 | 3 | 9 | Medium |
| Slips on uneven surface | 4 | 2 | 8 | Medium |
| Traffic collision | 3 | 5 | 15 | High |
| Utility damage | 2 | 5 | 10 | High |
| Manual handling | 4 | 2 | 8 | Medium |
| Heat stress | 3 | 3 | 9 | Medium |
4. Control Measures
Engineering Controls:
- Use equipment with built-in guards, reverse alarms, and emergency stops.
- Apply water spray or dust suppression systems on cutting areas.
- Install physical barricades and cones around the site.
- Use proper compaction and surface leveling machines.
- Ensure bitumen distributors are insulated and maintained.
Administrative Controls:
- Develop and implement a Traffic Management Plan.
- Issue a Permit to Work (PTW) for road cutting and hot work.
- Provide shift rotation for long or hot workdays.
- Conduct pre-work toolbox talks and daily safety briefings.
- Coordinate with utility service providers before cutting.
- Display road signage for speed limits, detours, and hazards.
Personal Protective Equipment (PPE):
- Flame-resistant clothing and gloves for paving crew.
- High-visibility reflective vest.
- Safety boots with heat-resistant soles.
- Dust masks and respirators.
- Hearing protection (ear plugs/muffs) and anti-vibration gloves.
- Safety helmets and eye protection.
5. Safe Work Procedure (SWP)
Before Work Begins:
- Conduct a detailed Job Hazard Analysis (JHA).
- Confirm utility locations and obtain permits/drawings.
- Mark work zones and install barricades and diversion signs.
- Check equipment functionality and PPE availability.
- Brief crew on hazards, first aid, and emergency contacts.
During Road Cutting and Paving:
- Maintain a safe distance between workers and machines.
- Operate cutting and paving machinery only by trained personnel.
- Ensure bitumen is heated within safe temperature limits.
- Apply water spray to reduce dust.
- Monitor wind direction to minimize dust/fume exposure.
- Keep first aid kits and burn treatment readily accessible.
After Completion:
- Cool machinery before relocation or cleaning.
- Inspect the area for hazards like loose material, sharp tools.
- Collect debris and waste for safe disposal.
- Remove barricades and signage only after the area is deemed safe.
- Report and document any incidents or near-misses.
6. Emergency Preparedness
- Maintain burn kits, fire extinguishers, and first aid boxes near hot work zones.
- Display emergency contact numbers and route maps.
- Provide rescue and response training to shift leads and safety staff.
- Conduct mock drills for electrocution, fire, and traffic impact.
- Keep traffic marshals or flagmen equipped with stop/go paddles and whistles.
7. Roles and Responsibilities
| Role | Responsibility |
|---|---|
| Site Engineer | Approve method statement and layout plans |
| HSE Officer | Conduct inspections, enforce PPE and controls |
| Supervisor | Monitor daily work, implement safety procedures |
| Equipment Operator | Safely operate road cutting and paving machines |
| Laborer | Assist with manual tasks, report unsafe conditions |
| Traffic Marshal | Direct vehicle and pedestrian traffic safely |
| First Aider | Respond to injuries including burns and heat exhaustion |
Summary of Key Recommendations
- Always coordinate with utility companies before cutting roads.
- Enforce strict use of PPE and ensure proper hydration of workers.
- Use a Traffic Management Plan with diversions, barriers, and trained marshals.
- Apply dust suppression and noise/vibration control where possible.
- Keep burn and first aid kits readily accessible near hot paving zones.
- Prohibit untrained workers from using cutting/paving machines.
- Maintain clear communication between all workers through handheld radios or visual signals.
Monitoring and Review
- Conduct daily site audits and housekeeping checks.
- Review incident logs and hazard reports weekly.
- Use job rotation to reduce repetitive strain or heat exposure.
- Update HIRA whenever new machinery, material, or method is introduced.
- Schedule refresher training for operators and traffic control teams.
Conclusion
Road cutting and paving may appear routine, but they involve numerous hazards that demand proactive safety planning and discipline. A strong HIRA process, supported by site controls, proper training, and worker vigilance, significantly reduces the risk of injury, illness, and project delays.
By following these safety measures and instilling a culture of hazard awareness, project teams can carry out roadwork operations efficiently while ensuring the well-being of everyone on-site.
