Handling & PPE
- Handle in a well-ventilated area or under a chemical fume hood.
- Avoid contact with skin, eyes, and clothing.
- Keep container tightly closed when not in use.
- Store in a cool, dry, and well-ventilated place.
- Store away from incompatible materials.
- Wear a standard laboratory coat or protective clothing.
- Wear compatible chemical-resistant gloves (e.g., nitrile or neoprene).
- Wear eye protection such as safety glasses with side-shields or chemical goggles.
- Use respiratory protection if ventilation is inadequate or exposure limits are exceeded.
First Aid / Accidental Release
- In case of eye contact, immediately flush eyes with plenty of water for at least 15 minutes.
- For skin contact, wash affected area thoroughly with soap and water.
- If inhaled, move to fresh air and keep at rest in a comfortable position.
- If swallowed, rinse mouth with water and do not induce vomiting.
- Seek medical attention if irritation persists or symptoms develop.
- Avoid dust or aerosol generation during cleanup.
- Ensure adequate ventilation in the area of release.
- Wear appropriate personal protective equipment, including gloves and eye protection.
- Collect spilled material using trained laboratory procedures.
Firefighting / Stability
- Use water spray, dry chemical, carbon dioxide, or appropriate foam for extinguishment.
- Wear self-contained breathing apparatus and full protective gear for firefighting.
- Keep containers cool with water spray to prevent rupture.
- Prevent runoff from fire control from entering waterways or sewers.
- Stable under recommended storage and handling conditions.
- May react with strong oxidizing agents.
- Avoid contact with strong acids and strong bases.
- Hazardous decomposition products may include carbon oxides, nitrogen oxides, and hydrogen chloride.
