Raising The Bar Guidance - Road Sweeper / Collector Equipment Requirements

The Road Sweeper, also known as a Road Sweeper Collector, is a critical piece of equipment for maintaining clean and safe road surfaces on construction sites and highways. This machine collects debris, dust, and loose materials, minimizing environmental pollution, improving road safety, and maintaining compliance with regulations. However, due to its movement, suction, and rotating brushes, strict adherence to safety standards is necessary to prevent accidents and manage environmental risks. National Highways’ "Raising the Bar 1" guidelines outline specific requirements to ensure the safe and efficient operation of road sweepers on all projects.

General Minimum Requirements

The General Minimum Requirements (GMR) establish baseline safety standards for all types of equipment, including Road Sweepers:

1. Daily Inspections: Road Sweepers must undergo thorough pre-use inspections every day. Operators should complete a checklist to detect any potential issues that could compromise safety or equipment functionality, such as hose blockages or damaged brushes.

2. Compliance with Legislation: Road Sweepers must meet UK regulatory standards, including compliance with UKCA certification and the European Commission Machinery Directive (2006/42/EC), with a declaration of conformity.

3. Safety Decals and High-Visibility Markings: Safety decals must be clear, legible, and visible on the machine. Access points, handrails, and operational controls should be marked with high-visibility colours to facilitate safe use.

4. Seat Belts: Functional seat belts are mandatory for the operator’s seat and must be worn at all times during operation to enhance safety.

5. Public Highway Compliance: Road Sweepers used on public roads must have appropriate registration plates, fully functional lights, and flashing amber beacons in line with Chapter 8 of the Traffic Signs Manual.

Equipment-Specific Safety and Compliance Standards

Due to its moving parts, suction systems, and close proximity to traffic and pedestrians, the Road Sweeper requires additional safety standards for efficient and safe operation:

1. Amber Beacon and Seat Belt Indicator: An amber beacon should be installed to increase visibility, and an external green light should signal when the operator’s seat belt is fastened. The green light may be turned off on public highways if required by lighting regulations.

2. 360° Visibility Standards: Road Sweepers must meet 360° visibility requirements using mirrors, cameras, or other visual aids to ensure the operator can see around the vehicle, especially when navigating around pedestrians or other vehicles.

3. Reversing Alarm: A directional, white-noise reversing alarm should be installed to alert nearby personnel and pedestrians when the Road Sweeper is reversing. The alarm should be clearly audible outside the cab.

4. Brush and Suction Control Safety: Brush and suction controls should be easily accessible and clearly labelled. Operators should be trained to disengage these functions when not in use to prevent accidents.

5. Debris Container and Hopper Locking: The debris container and hopper must be securely locked during transport and operation. Operators should check these locking mechanisms as part of their daily inspections.

6. Dust Suppression System: Road Sweepers must be equipped with a dust suppression system to minimize airborne dust, which can pose respiratory hazards and affect nearby traffic visibility.

7. Emergency Stop Button: A clearly marked emergency stop button should be accessible to the operator, allowing for immediate shutdown of all functions in case of an emergency.

8. Anti-Roll Stability: Road Sweepers must be designed with anti-roll stability to prevent tipping, particularly when operating on inclines or uneven surfaces.

Dust and Emission Control Standards

Dust and emissions control are crucial to minimize environmental impact and ensure operator and public safety:

1. Dust Suppression Water System: Road Sweepers should use a water-based dust suppression system to reduce airborne dust during sweeping. The water tank should be filled before each use, and operators should monitor water levels during operation.

2. Stage V Emission Compliance: For projects emphasizing environmental impact, Road Sweepers should comply with Stage V emission standards to reduce pollutants and align with environmental goals.

3. Enclosed Hopper: The debris hopper should be enclosed to prevent dust and debris from escaping, especially when operating in windy conditions.

4. Air Filter Maintenance: Air filters should be regularly inspected and maintained to ensure effective dust filtration, protecting both the operator and the environment.

Operator Competency and Requirements

The competency of the operator is essential to safe and efficient operation of a Road Sweeper. The following standards apply:

1. Licensing and Certification: Operators must hold the appropriate driving license category and any additional certifications required for operating a Road Sweeper on public roads.

2. Safety and Familiarization Training: Operators must receive training specific to the model and type of Road Sweeper, including operation of the brushes, suction system, and debris container.

3. Dust Control Knowledge: Operators should be trained in dust control measures, including use of the dust suppression system and understanding of how weather conditions can impact dust levels.

4. Ground Condition Awareness: Operators should be trained to assess ground conditions, particularly in construction zones or near road edges, to avoid tipping and ensure stable operation.

5. Emergency Procedures: Operators must be familiar with emergency stop procedures and how to safely disengage the brushes and suction in case of equipment malfunction.

Desirable Features

Additional features are recommended to improve safety, efficiency, and environmental compliance for Road Sweepers:

1. 360º Camera System: A 360º camera system enhances visibility, helping operators detect obstacles, personnel, or other vehicles in the surrounding area, especially when manoeuvring in confined spaces.

2. Pedestrian Detection System: Some camera systems offer pedestrian detection, alerting operators if people are within a 5-meter range, which is particularly useful in busy or urban areas.

3. Stage V Engine Emission Compliance: For environmentally conscious projects, a Stage V-compliant engine is recommended to reduce emissions, especially when working in sensitive or urban areas.

4. Automatic Water Refill System: An automatic water refill system for the dust suppression tank can enhance operational efficiency, ensuring that the tank remains adequately filled during extended use.

5. Hopper Level Indicator: A hopper level indicator helps the operator monitor debris levels, reducing the likelihood of overfilling and subsequent spillage or dust release.

6. Anti-Collision Sensors: Anti-collision sensors improve safety by alerting operators to nearby obstacles, reducing the risk of accidental contact with vehicles, structures, or pedestrians.

Hazard Identification and Mitigation

Operating a Road Sweeper involves specific risks, and proper hazard mitigation is essential to maintain safety:

• Tipping Risks: Road Sweepers are at risk of tipping, particularly when operating on slopes or with a full debris hopper. Anti-roll stability and thorough ground assessments are crucial to avoid tipping incidents.

• Dust Hazards: Without proper dust control, Road Sweepers can generate significant airborne dust, impacting nearby pedestrians, workers, and vehicles. Dust suppression systems must be fully functional, and water levels should be checked before operation.

• Debris Discharge Risks: If the hopper is overfilled or improperly secured, debris can spill onto the road, creating hazards for other road users. Regular monitoring of hopper levels and secure locking mechanisms help mitigate this risk.

• Proximity to Other Vehicles and Pedestrians: Road Sweepers are often used on busy roads or near pedestrian walkways, which can create collision risks. A 360º camera system, pedestrian detection, and reversing alarm help minimize these risks.

• Noise Exposure: Road Sweepers generate considerable noise, potentially affecting nearby workers and the public. Operators should wear hearing protection, and noise reduction measures, such as low-noise brush and suction systems, are recommended.

• Rotating Brush Hazards: The rotating brushes can be hazardous to nearby personnel if not properly disengaged. Operators should turn off the brushes when not in use and should be aware of the brush’s swing radius to avoid accidental contact with obstacles or people.

Summary

The Road Sweeper is an essential piece of equipment for maintaining safe and clean road surfaces on construction sites and highways. However, the suction, rotating brushes, and close proximity to traffic and pedestrians require strict adherence to National Highways’ "Raising the Bar 1" standards. By following protocols such as daily inspections, 360° visibility, and dust suppression, operators and site managers can ensure safe and effective use of Road Sweepers. Additional features like a 360° camera system, pedestrian detection, and anti-collision sensors can further enhance safety, efficiency, and environmental compliance.
