Safety Information
- Wear appropriate PPE including gloves, goggles, and protective clothing during handling.
- Avoid inhalation of dust and direct contact with eyes or skin.
- Use in well-ventilated areas to minimize exposure.
- Store in tightly sealed containers in a cool, dry area away from acids and oxidizing agents.
- Do not mix with strong acids as sulfur dioxide or toxic gases may be released.
- In case of eye contact, rinse immediately with plenty of clean water and seek medical attention if irritation persists.
- In case of skin contact, wash thoroughly with soap and water.
- If inhaled, move to fresh air and seek medical attention if symptoms occur.
- Clean spills carefully and avoid environmental release where possible.
- Always consult the latest Safety Data Sheet (SDS) before handling, storage, or transport.
