Occupational Safety Training in Speaker Manufacturing

1. Overview of Speakers

a. What are speakers?

Speakers are devices that convert electrical signals into sound, allowing users to play audio signals from devices such as computers, mobile phones, CD players, or audio amplifiers to enjoy music or watch movies. Speakers are manufactured in various sizes and designs to suit users’ needs.

b. Machinery used in speaker production

The speaker production process usually includes the following steps:

• Cutting and bending metal sheets: This process uses metal cutting and bending machines to shape and size speaker components such as frames, speaker cones, and base covers.
• Assembling the speaker driver: The components of the speaker driver are assembled and tested before being mounted onto the speaker frame.
• Assembling the speaker diaphragm: The diaphragm is mounted onto the speaker driver and positioned on the base cover.
• Assembling the speaker base: The base cover is assembled onto the speaker frame and glued for stability.
• Testing and inspection: Products are tested and inspected before packaging and shipment.

Common machinery used in speaker production includes metal cutting machines, metal bending machines, speaker driver assembly machines, drying and diaphragm pressing machines, audio testing machines, packaging machines, and transport equipment.

2. Overview of occupational safety training for speaker production

This article focuses on issues related to Group 3 because Group 3 directly participates in the production process and faces the highest occupational safety risks. For other groups, refer here.

a. What is Group 3 occupational safety training?

• Group 3 occupational safety training consists of sessions that equip workers with knowledge on preventing workplace accidents.
• The training course helps workers recognize and avoid hazards, reducing the risk of accidents during work.

b. Training duration

Initial safety training

• Total training time is at least 24 hours, including examination time.
• 8 hours of theory on safety and occupational hygiene policies and regulations
• 8 hours of theory on basic knowledge of occupational safety and hygiene
• 4 hours of theory on specialized training content
• 2 hours of practical exercises on specialized training content
• 2 hours of theoretical examination at the end of the course

The safety training center distributes the hours across multiple sessions depending on the workers’ schedule. Typically, there are 6 training sessions over 3 days if the company can arrange consecutive learning hours.

Periodic safety training

• Before the occupational safety card expires, workers seeking renewal must complete a periodic occupational safety training, with periodic training hours equal to at least 50% of the initial training hours.

Explanation: total periodic safety training time is at least 12 hours, including examination time. Upon completing the course and passing the test, the worker’s safety card will be renewed.

c. Training content

d. Occupational safety card

After completing the occupational safety training and passing the assessment, workers will be issued an occupational safety card (commonly called Group 3 safety certificate).

The Group 3 safety card displays information such as full name, date of birth, job, and specific working environment. It also includes training duration, a red stamp, and signature confirming course 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, stamp, and seal the safety card for Group 3 workers after they complete training from a certified occupational safety training unit and pass the assessment.
• If the worker is freelance or temporary, without a labor contract, the training unit must sign, stamp, and seal the safety card after the worker completes the training and passes the assessment.

3. Identifying Hazards Affecting Workers in Speaker Production

Potential hazards in the speaker production process may include:

• Risk of dust and chemical exposure: The speaker production process may use chemicals and materials that emit harmful dust such as formaldehyde, cyanide, acetone, butanone, toluene, and other chemicals. When employees inhale this harmful dust, it can cause health problems such as pneumonia, asthma, and cancer.
• Risk of noise exposure: Speaker production often involves machinery and equipment that generate noise. Noise can cause stress, insomnia, reduced work performance, and increase the likelihood of accidents due to distraction.
• Risk of occupational accidents: Employees participating in speaker production may need to use machinery and tools such as cutting machines, nail guns, grinders, welding machines, and hand tools. Improper use or lack of regular maintenance can lead to occupational accidents.
• Electrical hazards: If electrical equipment in the factory is not regularly maintained, lacks insulation, or is not waterproof, it can pose a risk of electric shock to workers during production.
• Risk of musculoskeletal injuries: Jobs in speaker production may require workers to stand or sit for long periods and repeatedly use their hands. Working in these positions can cause back pain, neck pain, and other musculoskeletal injuries.

4. Common Occupational Accidents in Speaker Production

Common occupational accidents in speaker production may include:

• Hand and finger injuries: Workers often use hand tools to attach and assemble speaker components. Continuous use of hands and fingers for extended periods can cause injuries or repetitive strain disorders.
• Eye injuries: During speaker production, workers may operate cutting or grinding tools that generate dust and debris. Without proper protective equipment, dust and debris can enter the eyes and cause injuries or eye diseases.
• Ear injuries: Noise during speaker production can cause ear damage if workers do not use protective equipment correctly.
• Back injuries: Lifting and moving speaker components can cause back injuries if proper lifting techniques are not followed.
• Machine-related injuries: Workers frequently operate large machines for speaker production. Failure to follow safety procedures during operation and maintenance can result in accidents such as crushing, cuts, or collisions.
• Electric shock: Workers deal with electrical equipment during production. Failure to comply with electrical safety rules increases the risk of electric shock.

5. Safety Measures When Participating in Speaker Production

Safety measures to be implemented in speaker production include:

• Ensuring safety during machinery and equipment operation: Machines and equipment must be regularly maintained to ensure stable and safe operation.
• Use of protective equipment: Employees should wear protective gear such as safety glasses, masks, gloves, ear protection, and safety shoes to protect eyes, hands, ears, feet, and head from materials, chemicals, and noise during production.
• Occupational safety training: New employees should be trained in production processes and safety measures, while existing employees need to update their knowledge on the latest safety procedures.
• Ensure ventilation and lighting: Speaker production factories should have proper ventilation and lighting to provide a safe and healthy working environment.
• Waste management: Factories must properly manage waste to ensure safety and minimize negative environmental impact.
• Control negative effects from machinery: Factories should control negative impacts such as vibration, noise, and high temperatures to maintain a safe working environment.
• Conduct safety inspections: Employees should regularly inspect machines and equipment to detect and address safety issues promptly.
• Ensure safety during transportation: Speakers should be transported properly to avoid accidents during handling and transport.
• Periodically conduct workplace environmental monitoring in factories, collect and analyze harmful factors to adjust and reduce hazards, thereby preventing occupational diseases.
