Occupational Safety Training for Operating Vibro Hammer Vehicles

1. Overview of Vibro Hammer Vehicles

a. What is a Vibro Hammer Vehicle?

A vibro hammer, also called a vibro hammer machine, is a type of equipment used in the construction industry to drive piles or pile structures into the ground using vibration principles. Specifically, the vibro hammer generates vibrations at the top of the pile or structure, causing it to penetrate the soil.

Using a vibro hammer increases efficiency and reduces the time required compared to manual pile driving or other traditional methods. It is an essential tool in constructing bridges, buildings, seaports, and other projects requiring secure pile installation.

b. How Vibro Hammer Vehicles Work

The operating principle of a vibro hammer is based on generating vibrations to drive piles or structures into the ground. Here is a detailed description of how a vibro hammer works:

• Generating Vibration:
  • The machine has a vibration engine or vibration system, typically powered by electric or combustion engines.
  • The engine produces vibrations at the required frequency and intensity.
• Transmitting Vibration:
  • Vibrations are transmitted from the engine to the pile or structure via vibration transmission devices, usually vibration units or bolts.
  • The pile or structure is positioned on the vibro hammer head, enhancing vibration intensity at the contact point.
• Driving into the Ground:
  • Vibrations at the contact point between the pile and soil reduce friction, allowing the pile to penetrate the ground more efficiently.
  • For soft soil, vibrations loosen the soil, decreasing resistance to pile penetration.
• Controlling Direction and Depth:
  • The vibro hammer control system monitors and manages pile penetration.
  • Measurement and control devices help determine the direction and depth of pile insertion accurately.

c. Industries Using Vibro Hammer Vehicles

Vibro hammer vehicles are mainly used in construction and infrastructure industries. Some sectors where vibro hammers are commonly applied include:

• Bridge and Road Construction: Vibro hammers are used to drive piles for bridge and road projects, ensuring stability and firm foundations.
• Seaport and Marine Construction: For ports and marine structures, vibro hammers drive piles for platforms, scaffolding, and other marine structures.
• Building and High-Rise Construction: Vibro hammers are used for large-scale building projects to install piles efficiently.
• Infrastructure Development: They are applied in infrastructure projects like railways, roads, and urban development.
• Energy Projects: In the energy sector, vibro hammers drive piles for wind farms, solar energy stations, or other energy-related infrastructure.
• Oil and Gas Projects: In oil and gas operations, vibro hammers install piles for offshore rigs, platforms, and related equipment.

2. Overview of Safety Training for Operating Vibro Hammer Vehicles

a. What is Occupational Safety Training?

• Occupational safety training for vibro hammer operators consists of sessions designed to raise awareness and prevent workplace accidents. Employees directly operating vibro hammer vehicles belong to Group 3.
• Training helps workers identify and prevent hazards, reducing the risk of workplace accidents during operations.

b. Training Duration

Initial Safety Training Duration:

• Total training time is at least 24 hours, including examination time.
• 8 hours of theory on policies and occupational safety and hygiene laws
• 8 hours of basic occupational safety and hygiene knowledge
• 4 hours of specialized training theory
• 2 hours of practical exercises in specialized training
• 2 hours of final theoretical examination

Safety training centers may split the course into multiple sessions depending on workers’ schedules. Typically, there are 6 training sessions over 3 days, if continuous attendance is possible.

Periodic Safety Training:

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

Explanation: total periodic safety training must be at least 12 hours, including examination time. After completing the periodic course and passing the test, the worker is reissued or renewed the occupational safety card.

c. Training Content

d. Occupational Safety Card

After completing safety training and passing the examination, workers are issued an occupational safety card (commonly referred to as Group 3 safety certificate).

Group 3 safety cards display information such as full name, date of birth, job, and specific working environment. It also includes training duration, red seal, and signature confirming course completion.

According to 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 and stamp the safety card after the worker completes the training from a certified safety training unit and passes the test.
• If the worker is freelance or seasonal, without a labor contract, the training unit must sign and stamp the safety card after the worker completes the training and passes the test.

3. Hazards When Operating a Vibratory Pile Hammer Vehicle

Operating a vibratory pile hammer vehicle can involve several hazards, and operators must follow safety measures to minimize risks. Below are some common hazards when operating a vibratory pile hammer vehicle:

• Risk of Engine Vibration Exposure: Workers near the vibratory pile hammer may be exposed to engine vibrations, which can cause damage to muscles and bones, especially if proper personal protective equipment (PPE) is not used.
• Risk of Injury from Vibrations: Strong vibrations from the vehicle can create discomfort and fatigue, and without proper PPE, workers may suffer from musculoskeletal injuries.
• Risk of Electric Shock: Failure to follow electrical safety procedures when working with the vehicle’s electrical systems can result in the risk of electric shock.
• Risk of Mobile Vehicle Accidents: During movement of the vibratory pile hammer, accidents may occur if the operator is inattentive or if the steering system malfunctions.
• Risk of Falling Materials: During piling or work on structures, materials may fall from height, posing injury risks to workers below.
• Potential Ground Impact: Operating the vibratory pile hammer may create ground impacts, which if not properly controlled, can endanger surrounding structures or reduce construction quality.

4. Safety Control Measures When Operating a Vibratory Pile Hammer Vehicle

To control and minimize occupational accidents when operating a vibratory pile hammer vehicle, safety measures must be strictly implemented. Below are some measures managers and workers can follow to ensure safety:

• Training and Guidance: Continuous and comprehensive training for operators is essential. They need to understand safety rules, operating procedures, and emergency response methods.
• Use of Personal Protective Equipment: Anyone working near the vehicle must wear full PPE, including helmets, safety goggles, fire-resistant clothing, gloves, and safety shoes.
• Regular Inspection and Maintenance: Establish a regular inspection and maintenance schedule for the vehicle to ensure all systems and components are functioning correctly.
• Vibration Control: Limit working time near the vehicle to reduce vibration exposure. Provide vibration protective equipment if prolonged work is required nearby.
• Movement Management: Define safe working zones and control vehicle movement. Avoid areas with workers and clearly mark safety zones.
• Ground Impact Monitoring: If the vehicle creates ground impacts, use monitoring equipment to ensure surrounding structures and the work environment are not affected.
• Compliance with Safety Rules: Ensure all personnel comply with safety regulations and industry standards. Avoid skipping safety measures.
• Use of Safety Devices: Utilize safety devices such as warning systems, lights, and automatic control systems to reduce accident risks.
• Hazard Zone Classification: Clearly classify and mark hazard zones around the vehicle, especially areas in direct contact with piles or structures.
• Electrical Source Control: Ensure the electrical supply to the vehicle is strictly controlled and complies with electrical safety regulations.
• Periodic inspection of the vehicle to detect early safety issues such as mechanical wear or failure, reducing the risk of occupational accidents.
