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 gloves, and eye protection.
Wear respiratory protection if ventilation is inadequate or if there is a risk of dust/aerosol exposure.
Ensure eye wash stations and safety showers are available.
Gloves should be inspected prior to use.

First Aid / Accidental Release

In case of inhalation, move to fresh air. If not breathing, give artificial respiration.
For skin contact, wash with plenty of soap and water. Remove contaminated clothing.
In case of 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 according to institutional procedures if irritation or symptoms persist.
For spills, avoid dust or aerosol generation.
Evacuate personnel to safe areas.
Ensure adequate ventilation.
Collect spilled material using trained-lab procedures and appropriate tools.

Firefighting / Stability

Use extinguishing media appropriate for the surrounding fire.
Wear self-contained breathing apparatus for firefighting if necessary.
Wear full protective gear to prevent contact with skin and eyes.
Keep containers cool with water spray.
This material is considered stable under recommended storage conditions.
Avoid strong oxidizing agents.
Avoid strong acids and strong bases.
May react with incompatible materials.
No known hazardous decomposition products under normal conditions of storage and use.
