3. Identifying hazards affecting workers during hair straightener production
During hair straightener production, potential hazards that may affect workers’ health include:
- Fire and explosion risk: Using chemicals and oils can cause fire or explosion hazards, especially if fire safety regulations are not followed.
- Burn risk: Hair straighteners operate at high temperatures, which can cause burns during production.
- Machinery accident risk: Workers may suffer accidents when operating machinery, especially without proper personal protective equipment such as helmets, safety glasses, gloves, etc.
- Electric shock risk: Poorly maintained or improperly insulated electrical equipment may cause electric shocks.
- Back and neck pain risk: Workers often stand or sit for long periods while operating machinery, potentially causing back and neck pain.
- Eye strain risk: Frequent use of machinery may affect workers’ vision, particularly if factory lighting safety regulations are not observed.

4. Common Workplace Accidents for Workers Producing Hair Straighteners
Common workplace accidents that may occur during the production of hair straighteners include:
- Fire and explosion: During production, chemicals, especially preservatives and plasticizers, can create high temperatures and are flammable. In addition, high voltage can also cause fire or explosion hazards for electronic devices such as production machinery for hair straighteners.
- Injury from trauma: Accidents related to trauma can occur due to mechanical production equipment, cutting tools, machinery, hand tools, and electronic devices in the factory. Sharp metal materials, drill bits, cutting knives, screwdrivers, screws, and other tools can cause injuries to workers.
- Burns: Due to high temperatures during hair straightener production, materials such as plastic, metal, rubber, and other chemicals may pose burn hazards to workers.
- Mental health: Work pressure, continuous work in noisy and dusty environments can cause stress and negatively affect workers’ mental health.
- Respiratory diseases: Inhaling polluted air in the hair straightener production factory can lead to respiratory issues for workers, including bronchitis, pneumonia, asthma, and allergies.
- Environmental factor impacts: Factories producing hair straighteners need to pay attention to environmental factors such as temperature, humidity, cleanliness, and lighting to ensure worker safety and health.
