Fire Fighting：

NO water. NO hydrous agents. Use dry powder, dry sand. In case of fire: keep cylinder cool by spraying with water. NO direct contact of the substance with water.

Spillage Disposal：

Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Sweep spilled substance into covered dry plastic containers. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT wash away into sewer.

Safe Storage：

Inhalation Risk：

A harmful concentration of airborne particles can be reached quickly when dispersed.

Effects of Short Term Exposure：

The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation may cause lung oedema, but only after initial corrosive effects on eyes and/or airways have become manifest.

Fire Prevention：

NO open flames, NO sparks and NO smoking. NO contact with water.

Exposure Prevention：

AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!

Inhalation Prevention：

Use local exhaust and breathing protection.

Skin Prevention：

Protective gloves. Protective clothing.

Eye Prevention：

Wear face shield or eye protection in combination with breathing protection.
