Guidance on Safe Use

First-aid measures

General advice: Pay attention to self protection and imediately call for a doctor. Take off immediately all contaminated clothing.

Inhalation: In the event of inhalation (ingestion), seek medical attention immediately.  Move into fresh air and keep at rest. If breathing stops, immediately begin artificial resuscitation. If the heart stops beating, immediately begin heart massage.

immediately.

Eye contact: Rinse the eye with water immediately.

Ingestion: Rinse mouth. Do NOT induce vomiting.

Fire-fighting measures

Suitable extinguishing media: Dry chemical. Alcohol-resistant foam. Carbon dioxide.

Extinguishing media which shall not be used for safety reasons: Water. Reacts violently with water.

Specific hazards during fire fighting: In case of fire, formation of hydrochloric acid, highly dispersed silicic acid.

Accidental release measures

Personal precautions, protective equipment and emergency procedures: Remove sources of ignition. Avoid contact with eyes, skin, and clothing.

Methods for cleaning up: Do not allow runoff to sewer, waterway or ground. DO NOT USE WATER
