Occupational Safety Training for Operating Motor Graders

1. Overview of Grader Trucks

a. What is a Grader Truck?

A grader truck is a specialized vehicle used in construction and road works. It is also called a motor grader or land leveling machine. The primary function of a grader truck is to cut and level the ground to create a smooth and even surface, often used for roads or airports.

Grader trucks usually have a front blade that can be adjusted to create different slopes and curves on the ground surface. They also have large wheels for efficient movement over diverse terrains. Some graders also have pivoting capabilities for more precise work.

b. How Grader Trucks Work

The operation principle of a grader truck mainly involves using a blade to cut and level the ground surface. Detailed description of its working principle:

• Blade:
  • Blade structure: The grader truck has a wide front blade, usually made of hard steel to efficiently cut and level the ground.
  • Blade adjustment: The blade can be adjusted to change the cutting depth and tilt, allowing the grader to adapt to different terrains and specific tasks.
• Frame and wheels:
  • Load-bearing frame: Grader trucks have a strong frame to withstand the pressure from cutting and leveling operations.
  • Wheels: Large wheels provide stable movement across varied terrains. Some models can pivot for easier maneuvering.
• Control system:
  • Main controls: The operator uses controls to adjust the blade depth and steer the vehicle.
  • Blade control system: Adjusts the angle and tilt of the blade, determining how the ground is cut and leveled.
• Engine:
  • Powerful engine: Graders are equipped with strong engines to provide sufficient power for heavy-duty work and challenging terrains.
• Hydraulic system:
  • Hydraulic system: Provides hydraulic power to move and adjust key components like the blade and wheels.

c. Industries Using Grader Trucks

Grader trucks are primarily used in construction and roadwork. Key industries and applications include:

• Construction:
  • Building residential, industrial, and infrastructure projects.
  • Preparing ground surfaces for houses, buildings, and other structures.
  • Creating and maintaining road slopes, especially for highways and national roads.
• Roadwork:
  • Building and maintaining transportation networks.
  • Creating smooth and safe road surfaces for improved traffic safety and driver comfort.
• Mining:
  • Preparing land surfaces for mining operations.
  • Leveling extraction areas for safer and easier access.
• Agriculture:
  • In some cases, graders can be used to level land before planting or seeding.
• Industrial Processing:
  • Preparing land before building factory infrastructure or processing sites.
• Waste Management and Environmental Projects:
  • Leveling land during construction of waste treatment facilities and other environmental projects.
• Military:
  • Used for land preparation and infrastructure construction in military projects.

2. Overview of Occupational Safety Training for Grader Truck Operation

a. What is Occupational Safety Training?

• Occupational safety training for operating grader trucks provides sessions to raise awareness of workplace accident prevention. Workers directly involved with grader trucks belong to Group 3.
• This training helps workers identify hazards, prevent risks, and reduce workplace accidents during operation.

b. Training Duration

Initial safety training:

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

The safety training center schedules sessions according to workers’ availability. Typically, there are 6 sessions over 3 days if the company can provide continuous learning time.

Periodic safety training:

• Before the occupational safety card expires, workers must attend periodic safety training with a duration of at least 50% of the initial training.

Explanation: The total time for periodic safety training is at least 12 hours, including exams. After completion and passing the test, the safety card is reissued and renewed.

d. Occupational Safety Card

After completing the occupational safety training and passing the exam, workers will receive a Group 3 Occupational Safety Card (commonly known as Group 3 Safety Certificate).

This card shows full name, date of birth, job, work environment, training duration, official stamp, and signature confirming completion.

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

• If the employer and employee have a labor contract, the employer must sign and stamp the safety card for Group 3 employees after completing training and passing the exam.
• If the worker is freelance or temporary without a labor contract, the training unit must sign and stamp the safety card after completing training and passing the exam.

3. Hazards When Operating a Grader

Operating a grader requires caution and skill, and there are several hazards that operators and those around them need to be aware of. Here are some common hazards:

• Hazards to the Operator:
  • Protective Covers and Work Areas: Operators must avoid the machine’s working zones and protective covers to prevent accidents and injuries.
• Hazards to People Nearby:
  • Safe Zone: Operators must ensure that no one or no objects are near the working area of the grader to avoid collisions and accidents.
  • Warnings:
    • Grader operation can sometimes generate high noise levels, so safety measures and hearing protection are necessary.
    • Following safety warnings and rules is crucial to prevent accidents involving surrounding personnel.
• Environmental Hazards:
  • Ground Conditions: Unstable ground can lead to loss of control of the grader, especially on hilly or muddy terrain.
  • Bad Weather: During heavy rain or snow, tire traction may be reduced, increasing the risk of losing control.
• Equipment Hazards:
  • Cutting Blade: The blade can pose serious risk if not used properly or if maintenance issues exist. Operators must keep it sharp and safe.
  • Hydraulic System: Malfunctions in the hydraulic system can cause loss of vehicle control.
• Control-Related Hazards:
  • Loss of Control: Loss of control of the grader can occur if the operator does not use the controls correctly or if there are faults in the control system.

4. Measures to Prevent Work Accidents When Operating a Grader

To control and reduce the risk of work accidents while operating a grader, several important safety measures must be followed by operators and managers. Key measures include:

• Training and Retraining:
  • Ensure grader operators are fully trained in its operation and use.
  • Provide continuous and refresher training to update safety knowledge and new techniques.
• Regular Inspection and Maintenance:
  • Conduct regular inspections and maintenance to ensure the grader operates safely and properly.
  • Ensure cutting blades are sharp and critical systems, like hydraulics, are functioning correctly.
• Use of Personal Protective Equipment:
  • Operators and nearby workers must wear helmets to protect against head injuries.
  • Use safety glasses, ear protection, and appropriate safety shoes.
• Safety Planning:
  • Before starting work, operators and managers should plan for safety, identify potential hazards, and implement countermeasures.
  • Ensure the work area is cleared of unnecessary obstacles.
• Warning and Traffic Management:
  • Implement effective warning measures such as signs and lights to indicate the grader’s working zone.
  • Manage traffic carefully, especially when working on public roads.
• Ground Condition Management:
  • Monitor ground and weather conditions. Avoid working on unstable terrain or during adverse weather.
• Proper Use of Controls:
  • Learn to operate the grader’s controls safely and correctly.
  • Always check controls before starting work.
• Careful Interaction with Surrounding Personnel:
  • Maintain communication with nearby workers to ensure safety.
  • Avoid working close to people or vehicles without proper awareness and coordination.
• Regular Safety Checks:
  • Perform safety checks before each work session to ensure all systems function properly.
• Emergency Planning:
  • Have an emergency plan, including how to exit the vehicle if necessary.
• Periodic grader inspection to detect safety issues early, such as wear or mechanical failure, reducing the risk of work accidents.
