After inhalation:

Keep the patient calm. If unconscious place in stable sideways position. Protect against loss of body heat. If breathing stops, administer artificial respiration. Seek medical advice immediately and clearly identify substance.

After swallowing:

If conscious, give several small portions of water to drink. Do not induce vomiting. Seek medical advice immediately and clearly identify substance.

Indication of any immediate medical attention and special treatment needed

After inhalation: treat as early as possible using cortisone spray. Medical checks necessary up to a latency period of at least 24 hours. In the event of 1st degree burns use corticoid-externa. In the case of 2nd degree burns, use symptomatic treatment.

Fire-fighting measures

Extinguishing media

Suitable extinguishing media:

Use water spray (not stream) to fight fires, extinguishing powder, alcohol-resistant foam. For small amounts: carbon dioxide.

Extinguishing media which must not be used for safety reasons:

none known.

Special hazards arising from the substance or mixture

Hazardous combustion products: hydrogen chloride.

Advice for firefighters

Special protective equipment for fire fighting:

Use respiratory protection independent of recirculated air.

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Wear personal protection equipment. Task force: Use tightly fitting chemical protection suit. Keep unprotected persons away. Take persons to a safe place. Avoid contact with eyes and skin. Avoid inhaling mists and vapours. Observe wind direction.

Environmental precautions

Prevent material from entering sewers or surface waters. Contain any fluid that runs out using suitable material (e.g. earth). Dispose of in prescribed marked containers.

Methods and material for containment and cleaning up

Do not flush away with water. Absorb with a liquid binding material such as diatomaceous earth and dispose of according to local/state/federal regulations. For small amounts: Cover with calcium oxide. Contain larger amounts and pump up into suitable containers.

Further information:

Eliminate all sources of ignition.

Handling and storage

Precautions for safe handling

General information:

Avoid exposure by technical measures or personal protective equipment.

Precautions for safe handling:

Ensure adequate ventilation. Must be syphoned off in situ.

Precautions against fire and explosion:

Cool endangered containers with water. Flammable vapors may accumulate and form explosive mixtures with air in containers, process vessels, including partial, empty and uncleaned containers and vessels, or other enclosed spaces. Keep away from sources of ignition and do not smoke. Take precautionary measures against electrostatic charging.

Conditions for safe storage, including any incompatibilities

Conditions for storage rooms and vessels:

Unsuitable material for storage containers, casks and pipelines: light metals and their alloys, iron, steel, zinc. Store under protective gas. Test the suitability of materials for storage vessels, containers and piping.

Advice for storage of incompatible materials:

Observe local/state/federal regulations.

Further information for storage:

Store in the original container. Keep container dry and tightly closed. Store cool.
