• With the types of batteries, oils, and chemicals used in hearing aid manufacturing, there is a risk of fire and explosion if not stored and used properly.
• Chemicals, solvents, and other chemical substances used during the manufacturing process can be harmful to the health of production workers if not handled and used properly.
• Hearing aid manufacturing often requires many mechanical, assembly, and testing activities, so the risk of work accidents can occur if employees do not fully comply with work safety procedures.
• During the manufacturing process, employees may be exposed to ultraviolet rays from measuring, testing, or other equipment, which can affect their health.

4. Common work accidents in hearing aid manufacturing

The types of work accidents that commonly occur when manufacturing hearing aids include:

• Ear injuries: For jobs that require the use of tools such as knives, scissors, or cranes, not wearing appropriate ear protection can lead to ear injuries.
