Occupational Safety Training for Operating Road Rollers

1. Overview of Rollers Truck

a. What is a Rollers Truck?

A rollers truck (also called a roller, rollers truck) is a specialized vehicle commonly used in construction and roadwork. It is equipped with rolling drums, often heavy-duty, that help compact and level soil or other materials on road surfaces or construction sites.

The main function of a rollers truck is to compact and level layers of soil, stone, or other construction materials to create a uniform foundation for roads, airports, urban areas, or other construction projects. Compaction improves soil strength, reduces elasticity, and prevents soil movement during use.

Rollers trucks are typically used after soil has been distributed and leveled by other machinery such as excavators, bulldozers, or graders. For large construction projects, the use of rollers trucks is a critical part of building and maintaining infrastructure.

b. How Rollers Trucks Work

The operation of a rollers truck relies on rolling drums to generate pressure and compaction force required to densify layers of soil or construction material. Below is a detailed description of how rollers trucks work:

• Roller Drum: The main feature of a rollers truck is one or more rolling drums. These drums can be adjusted to increase or decrease pressure on the soil.
• Pressure and Compaction Force: As the rollers truck moves over the soil, the roller drums generate high pressure mainly from their own weight and the drum mechanism. This pressure is applied to the soil, creating compaction force.
• Compaction and Soil Densification: The applied force helps densify and compact the soil. This process reduces spaces between soil particles, improving mechanical properties and soil stability.
• Pressure Adjustment: If necessary, the operator can adjust the roller drum pressure to meet project-specific requirements using the vehicle’s hydraulic control system.
• Speed Control: Rollers trucks usually allow speed control to ensure even distribution of pressure and compaction across the working surface.

In summary, rollers trucks operate by using roller drums to create pressure and compaction force, helping densify soil layers to prepare for construction or infrastructure maintenance.

c. Industries Using Rollers Trucks

Rollers trucks are mainly used in construction and roadwork. Specific industries include:

• Road Construction: Compaction of soil layers is essential for building and maintaining roads. Rollers trucks create a uniform, dense surface, reducing elasticity and increasing soil strength.
• Infrastructure Construction: In projects like airports, ports, dams, and other public works, rollers trucks prepare the soil surface for subsequent construction stages.
• Urban and Industrial Development: For new urban areas or industrial zones, rollers trucks are used to compact soil and prepare surfaces for building structures.
• Road Maintenance and Land Management: Rollers trucks are also used for road maintenance and soil regulation to ensure stability and resist weather and daily usage effects.

2. Overview of Labor Safety Training for Operating Rollers Trucks

a. What is Labor Safety Training?

• Labor safety training for operating rollers trucks consists of lessons that equip workers with awareness and methods to prevent workplace accidents. Workers directly operating rollers trucks belong to Group 3.
• The safety training course helps workers identify and avoid hazards, reducing the risk of accidents while working.

b. Training Duration

Initial safety training:

• Total training hours are at least 24 hours, including exam time.
• 8 hours theory on policies and labor safety laws
• 8 hours theory on basic labor safety knowledge
• 4 hours theory on specialized training content
• 2 hours practical training on specialized content
• 2 hours final theory test

The training center will divide the program into multiple sessions depending on workers’ schedules. Typically, there are 6 sessions over 3 days if the company arranges continuous learning time.

Periodic safety training:

• Before the labor safety card expires, workers must attend periodic safety training if they want to renew it, with training hours being at least 50% of the initial safety training duration.

Explanation: Total periodic safety training is at least 12 hours, including exam time. After completing the course and passing the test, workers are reissued or have their labor safety card renewed.

d. Labor Safety Card

After completing the labor safety training and passing the exam, workers will be issued a labor safety card (commonly called Group 3 labor safety certificate).

The Group 3 card includes the worker’s full name, date of birth, job, working environment, training duration, red stamp, and signature confirming course completion.

According to the regulations in Clause 2 of Article 24, Decree 44/2016/ND-CP, there are two cases:

• If the employer and employee have a labor contract, the employer must sign, stamp, and validate the card after the employee completes training and passes the test.
• If the worker is freelance or seasonal and has no labor contract, the training unit must sign, stamp, and validate the card after the worker completes training and passes the test.

3. Hazards When Operating a Roller

Operating a roller can involve many hazards, especially if safety measures are not followed. Here are some common hazards:

• Injuries to Operators and Staff:
  • Collisions and Accidents: Rollers often operate in complex construction environments, and collisions with other objects such as motorcycles, pedestrians, or other construction vehicles can lead to serious accidents.
• Workplace Safety:
  • Steep Slopes and Inclines: Failing to follow safety rules when operating a roller on sloped terrain can cause tipping or loss of control, endangering the operator and staff.
• Mechanical Issues:
  • Equipment Malfunctions: If the roller is not regularly maintained or has technical issues, mechanical failures may occur, making operation hazardous.
• Environmental Conditions:
  • Harsh Weather Conditions: Operating a roller in extreme weather such as heavy rain, snow, or unstable ground conditions increases risks and may cause accidents.
• Working Near Other Construction Equipment:
  • Collisions with Other Equipment: In construction environments, rollers often work near other machinery. Collisions with them can create dangerous situations.
• Exposure to Toxic Substances:
  • Exposure to Hazardous Materials: If the construction site involves toxic substances, the operator and staff may be at risk of poisoning.
• Non-Compliance with Safety Rules:
  • Not Wearing Helmets or Protective Gear: Failing to wear proper safety equipment such as helmets increases the risk of head injuries in case of accidents.

4. Measures to Prevent Workplace Accidents When Operating Rollers

To prevent workplace accidents when operating rollers, safety measures must be strictly applied and followed. Here are some key measures:

• Training and Instruction:
  • Safety Training: Ensure that roller operators and related staff are fully trained in safe operation. This includes understanding the vehicle’s features, safety rules, and emergency response procedures.
• Regular Inspections and Maintenance:
  • Scheduled Maintenance: Perform regular maintenance on rollers to ensure all systems function properly and prevent sudden mechanical failures.
• Use of Safety Equipment:
  • Wear Helmets and Personal Protective Equipment: Require all operators and staff to wear helmets and protective gear to prevent head injuries and other hazards.
• Speed Control:
  • Maintain Safe Speed: Keep a safe speed, especially on uneven terrain or slopes.
• Monitor Working Environment:
  • Check Work Conditions: Monitor conditions including weather, humidity, and terrain to make safe operational decisions.
• Reduce Collision Risks:
  • Safe Driving Techniques: Apply safe driving techniques to reduce the risk of collisions with other staff or vehicles on site.
• Periodic Safety System Checks:
  • Inspect Safety Systems: Regularly check roller safety systems including brakes, warning lights, alarms, and other devices.
• Stop Work in Dangerous Conditions:
  • Cease Work When Necessary: If working conditions become too hazardous, stop work and reassess the situation before continuing.
• Establish Safe Zones:
  • Define Safety Areas: Set up and maintain safety zones around rollers to prevent others from entering and reduce collision risks.
• Internal Signaling and Traffic Systems:
  • Use Safety Signals and Internal Traffic Control: Ensure rollers are equipped with safety signals and internal traffic systems to warn others in the work area.
• Periodic inspection of rollers to detect early safety issues such as wear, mechanical faults, or defects, thereby reducing workplace accident risks.
