Occupational Safety Training for Handheld Angle Grinder Operation

1. Overview of Handheld Angle Grinders

a. What is a Handheld Angle Grinder?

A handheld angle grinder is a type of portable power tool used for grinding, cutting, or shaping various materials using a grinding or cutting disc. Angle grinders are commonly used in a wide range of applications, including construction, repair, metal fabrication, and various DIY tasks.

Handheld angle grinders typically have a grinding head of varying diameters depending on the specific task. They can be adjusted to grind or cut at different angles, enabling precise and versatile operations.

However, a handheld angle grinder is a powerful tool and must be used carefully following instructions to ensure user safety. Safety measures include wearing protective eyewear, masks, gloves, and protective clothing, as well as securing the grinder properly to prevent accidents.

b. Operating Principle of Handheld Angle Grinders

The operating principle of a handheld angle grinder is simple. It uses an electric motor to spin a disc at very high speed. This disc can be a grinding or cutting disc depending on the task.

Here is a basic overview of how a handheld angle grinder works:

• Power supply: When the grinder is connected to an electric source, it starts operating.
• Motor rotation: The motor inside the grinder generates rotational force, usually at high speeds, often between 5,000 and 10,000 RPM or even higher.
• Grinding or cutting disc: The motor transfers rotational power to the disc, creating a spinning surface for cutting or grinding.
• Grinding or cutting: When the disc is applied to the material with appropriate pressure, it grinds or cuts the material, depending on the disc type and applied force.

c. Industries that Use Handheld Angle Grinders

Handheld angle grinders are versatile tools used in various industries. Some common industries and applications include:

• Construction and installation: Used to cut, grind, and shape construction materials such as concrete, brick, wood, steel, and stone.
• Metal fabrication: Used for metal surface grinding, cutting metal, and removing defects on metal surfaces.
• Welding and repair: Welders and repair technicians use grinders to prepare metal surfaces before welding or to remove welding spatter and defects.
• Woodworking: Used for surface grinding, cutting, or shaping wooden components.
• Automotive repair: Mechanics use angle grinders to cut and grind metal parts on vehicles.
• Stone and gemstone processing: Used to create products and jewelry from stones and gems.
• DIY applications: Consumers use grinders for projects like garden construction, furniture making, and household repairs.

2. Overview of Safety Training for Operating Handheld Angle Grinders

a. What is Occupational Safety Training?

• Occupational safety training for operating handheld angle grinders consists of sessions designed to raise awareness on accident prevention for workers. Workers directly operating angle grinders belong to group 3.
• The training helps workers identify hazards and prevent accidents, minimizing risks in the workplace.

b. Training Duration

Initial safety training:

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

The safety training center schedules multiple sessions depending on worker availability. Typically, there are 6 sessions over 3 days, provided the employer can arrange continuous training time.

Periodic safety training:

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

Explanation: The total periodic safety training time is at least 12 hours, including testing. Upon completion and passing the test, workers receive renewed occupational safety cards.

c. Training Content

d. Occupational Safety Card

After completing the safety training and passing the test, workers receive an Occupational Safety Card (commonly called Group 3 Safety Certificate).

Group 3 cards display full information including name, date of birth, job, working environment, training duration, red stamp, and signature confirming completion.

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

3. Hazards When Operating a Handheld Angle Grinder

Operating a handheld angle grinder can involve many hazards if proper safety measures are not followed. Here are some common hazards when using a handheld angle grinder:

• Injuries and cuts: The grinding or cutting disc of a handheld angle grinder can cause injuries if not used carefully. Injuries may occur if the grinder slips off the material or if you do not control it accurately, potentially resulting in severe cuts.
• Dust and sparks: Angle grinders generate dust and sparks when grinding or cutting metal. Dust can be harmful to health, especially if you do not wear a respiratory mask. Sparks can cause fires or eye injuries if safety goggles are not worn.
• Electrical accidents: Handheld angle grinders are powered by electricity and have cords. Electrical accidents may occur if the cord is damaged or if safety precautions are ignored while using the grinder.
• Noise hazards: Handheld angle grinders produce extremely loud noise, and prolonged exposure can damage hearing. Wearing ear protection or earmuffs is essential for auditory safety.
• Disc hazards: Grinding discs can malfunction or break during use, creating a risk of serious injury. Regular inspection and maintenance of discs are crucial for safety.

4. Measures to Control Workplace Accidents When Operating a Handheld Angle Grinder

To control and reduce the risk of workplace accidents when operating a handheld angle grinder, follow these safety measures:

• Wear personal protective equipment (PPE):
  • Safety goggles: Protect your eyes from sparks, dust, and flying debris while using the grinder.
  • Hearing protection: Wear earplugs or earmuffs to protect hearing from high noise levels.
  • Respiratory mask: Use a respiratory mask when working in dusty environments, especially when grinding wood or metal.
• Adjust the angle grinder:
  • Ensure the angle grinder is regularly maintained and functioning properly.
  • Ensure the grinding or cutting disc is correctly and securely attached.
  • Check the motor, power cord, and switches before use.
• Work area safety:
  • Keep the work area clean and well-ventilated to reduce dust and fumes.
  • Ensure no one else is near the work area, maintaining a safe distance.
• Approach:
  • Keep hands and body away from the grinding or cutting disc to avoid injury.
• Speed control:
  • Use a speed appropriate for the specific task and material being processed.
• Machine control:
  • Hold the handheld angle grinder firmly and control it accurately while using.
  • Avoid applying excessive pressure to prevent the grinder from slipping off the material.
• Regular inspection of the handheld angle grinder to detect early safety issues such as wear, tear, or mechanical damage, reducing the risk of workplace accidents.
• Use quality angle grinders from reputable stores to ensure stability and safety of the equipment.
