Catalog reference cue; confirm supplier documentation before use.
Handling & PPE
- Handle in a well-ventilated area or fume hood.
- Avoid inhalation, ingestion, and skin/eye contact.
- Keep container tightly closed in a dry and well-ventilated place.
- Store away from incompatible materials.
- Ensure good laboratory hygiene practices are followed.
- Use appropriate PPE such as lab coat, compatible chemical-resistant gloves, and eye protection (safety goggles).
- Wear respiratory protection if ventilation is inadequate or exposure limits are exceeded.
- Ensure local exhaust ventilation is adequate to maintain airborne concentrations below occupational exposure limits.
- Wash hands thoroughly after handling and before eating, drinking, or smoking.
First Aid / Accidental Release
- In case of inhalation, move to fresh air. Seek medical attention if symptoms persist.
- For skin contact, wash with plenty of soap and water. Remove contaminated clothing.
- For eye contact, rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
- If swallowed, rinse mouth. Do NOT induce vomiting. Seek medical attention.
- Seek medical attention according to institutional procedures if irritation or symptoms persist.
- Avoid dust or aerosol generation.
- Ensure adequate ventilation during cleanup.
- Wear appropriate personal protective equipment, including respiratory protection if needed.
- Collect spilled material using trained laboratory procedures.
Firefighting / Stability
- Use dry chemical, carbon dioxide, water spray, or alcohol-resistant foam for extinguishing.
- Wear self-contained breathing apparatus and full protective gear for firefighting if necessary.
- Evacuate personnel to a safe area.
- Keep containers cool with water spray to prevent rupture.
- Stable under recommended storage conditions.
- Avoid strong oxidizing agents.
- May react with incompatible materials.
- No known hazardous decomposition products under normal conditions of storage and use.
