Occupational Safety Training for Piano Manufacturing

1. Overview of the Piano

a. What is a piano?

The piano is a type of keyboard instrument invented in the early 18th century by Bartolomeo Cristofori. It consists of a keyboard with white and black keys, each corresponding to a specific musical note. When a key is pressed, a small hammer inside strikes the string, producing sound.

Pianos are generally divided into two main types: acoustic pianos and digital pianos. Acoustic pianos use a mechanical system to create sound, while digital pianos use electronic technology to emulate the sound of acoustic pianos. Acoustic pianos are commonly used in concerts and professional performances, while digital pianos are more popular for learning and home practice.

The piano is not only a staple instrument in classical music but is also widely used in various genres such as jazz, pop, and rock. With its rich and expressive tonal range, the piano has become an essential tool for composition and performance worldwide.

b. Types of machinery used in piano manufacturing

The process of manufacturing a piano requires a combination of various machines and technologies to ensure precision and high quality. Below are some key machines used in piano production:

• Wood cutting and shaping machines: Since pianos are mainly made of wood, cutting and shaping machines are indispensable. These machines cut, grind, and shape wood components to the required size and form, including the soundboard, frame, and other parts.
• Frame bending machines: To create the curved shape of the piano, especially in acoustic pianos, manufacturers use frame bending machines. These machines bend thick wooden beams into curves without breaking or damaging the wood.
• Key drilling and installation machines: Piano keys must be precisely installed on the keybed. Key drilling and installation machines create accurate holes and secure the keys in place, ensuring smooth and precise key movement.
• Stringing and tensioning machines: A piano has hundreds of strings, each requiring precise tension and tuning. Automatic stringing and tensioning machines ensure each string is tightened to the exact tension and tuned to the required frequency.
• Grinding and polishing machines: Once the piano parts are assembled, the instrument’s surface needs to be polished for a smooth, glossy finish. Grinding and polishing machines refine the wood and metal surfaces of the piano.
• Sound testing and final finishing machines: Finally, sound testing machines are used to ensure the piano produces accurate and high-quality tones. The piano is then completed with final touches such as lid installation, legs, and other accessories.

c. Famous piano manufacturing brands

• Steinway & Sons: Founded in 1853 in New York, Steinway & Sons is one of the most prestigious piano brands in the world. Steinway pianos are known for their exceptional sound quality, durability, and elegant design. Many renowned pianists choose Steinway pianos for their performances.

b. Training Duration

Initial safety training duration

• The total training duration is at least 24 hours, including examination time.
• 8 hours of theoretical lessons on the system of occupational safety and hygiene policies and laws.
• 8 hours of theoretical lessons on basic occupational safety and hygiene knowledge.
• 4 hours of theoretical lessons on specialized training content.
• 2 hours of practical lessons on specialized training content.
• 2 hours for the final theoretical examination.

The training center will allocate the time into multiple sessions depending on the company’s scheduling for employees. Typically, there are 6 training sessions over 3 consecutive days if the production schedule allows.

Periodic safety training duration

• Before the occupational safety card expires, workers who wish to renew it must attend a periodic occupational safety training course, with a periodic training duration equal to at least 50% of the initial training duration.

Explanation: The total periodic training duration is at least 12 hours, including examination time. After completing the periodic training and passing the test, workers will have their occupational safety card renewed.

c. Training Content

See more training content for all 6 groups.

d. Occupational Safety Card

After completing the occupational safety training and passing the test, the worker will be issued an occupational safety card (commonly referred to as a Group 3 occupational safety certificate).

The Group 3 safety card clearly shows information such as: full name, date of birth, job title, and specific working environment, as well as the training duration, red seal, and signature confirming course completion.

According to the safety card issuance regulations specified in Clause 2, Article 24 of Decree 44/2016/NĐ-CP, there are two cases:

• If the employer and the employee have a labor contract, the employer must sign, stamp, and seal the safety card for Group 3 trainees after completing the training from a licensed occupational safety training unit and passing the test.
• If the worker is a freelancer, seasonal worker, or does not have a labor contract, the training unit must sign, stamp, and seal the safety card after the worker completes the training and passes the test.

3. Identifying Hazards Affecting Workers in Piano Manufacturing

• Mechanical injury risks:
  • Cuts and impacts: During the manufacturing and assembly process, there is a risk of workers being cut, pierced, or struck by sharp tools, machinery, or wooden and metal parts of the piano.
• Chemical hazards:
  • Use of chemicals: Chemicals such as adhesives, coatings, solvents, and cleaning agents can be harmful if not used properly. Appropriate personal protective measures and safe working procedures are required.
• Noise hazards:
  • High noise levels: The machining and tuning process of pianos can produce high noise levels, affecting workers’ hearing. Ear protection measures are necessary to minimize noise exposure.
• Dust and metal fume hazards:
  • Generation of dust and metal fumes: Wood and metal processing can produce wood dust and metal fumes, which are harmful to workers’ respiratory health. Suitable protective equipment such as respirators should be used to safeguard health.
• Ergonomic and musculoskeletal injury risks:
  • Working in uncomfortable positions: Piano assembly and tuning often require prolonged and awkward postures, which can lead to fatigue and musculoskeletal injuries such as back, neck, and shoulder pain.
• Temperature and workplace condition hazards:
  • Temperature and humidity: Piano manufacturing plants may have varying temperature and humidity levels, potentially affecting workers’ health. Environmental controls such as air conditioning and temperature management should be in place.
