Safety Precautions:
- Ensure proper ventilation at the construction site.
- No smoking or open flames in the construction area or nearby.
- Use explosion-proof electrical equipment.
- Metal impacts are strictly prohibited.
- Prevent static electricity buildup.
- Wear necessary protective gear.
- Avoid inhaling paint mist and prevent skin contact with paint and thinner.
- In case of accidental contact with the eyes, rinse thoroughly with plenty of water and seek medical attention promptly.
- Properly dispose of empty paint cans and leftover paint to avoid environmental pollution.
- Take all other necessary safety and fire protection measures based on the specific situation on site.
