Most important symptoms and effects, both acute and delayed

The substance is corrosive.

Indication of any immediate medical attention and special treatment needed

Treat symptomatically.

Fire-fighting measures

Suitable extinguishing media

Water spray, alcohol resistant foam, carbon dioxide (CO2), Dry extinguishing powder

Unsuitable extinguishing media

Full water jet

Special hazards arising from the substance or mixture

flammable, On intense heating explosible mixture with air possible.

Emission of irritating and toxic fumes and gases.

In case of fire may be liberated: Carbon oxides

In general: For flammable organic substances dust explosion potential is assumed when finely dispersed in air.

Advice for firefighters

Wear a self-contained breathing apparatus and chemical protective clothing.

Additional information

Use water spray jet to protect personnel and to cool endangered containers. Suppress gases/vapours/mists with

water spray jet. Collect contaminated fire extinguishing water separately. Do not allow entering drains or surface

water.

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Provide adequate ventilation. Avoid contact with skin, eyes and clothes. Use personal protection equipment.

Remove all sources of ignition. Avoid dust formation.

Assure emergency shower, eye shower near the workplace

Environmental precautions

Do not allow to enter into soil/subsoil. Do not allow to enter into surface water or drains.

Methods and material for containment and cleaning up

Take up carefully when dry. For larger quantities: Use suitable dust binding material.

Collect in closed and suitable containers for disposal. Clean up affected area.

Handling and storage

Advice on safe handling

Provide adequate ventilation. Working places should be designed to allow cleaning at any time. Avoid dust formation. Do not breathe dust. Avoid contact with skin, eyes and clothes. Use personal protection equipment.

Remove all sources of ignition.

Advice on protection against fire and explosion

Usual measures for fire prevention.

Further information on handling

Keep container tightly closed.

Handle in accordance with good industrial hygiene and safety practice: Do not eat, drink, and smoke. Wash hands before break and after work.

Conditions for safe storage, including any incompatibilities

Requirements for storage rooms and vessels:

Keep away from heat. Protect from sunlight. Keep in a cool, well-ventilated place.

Advice on storage compatibility

For storage in a common place refer to the respective regulations.

SpecialProvisions

Exposure controls / personal protection

Control parameters

Additional advice on limit values

Dust limits (inhalable and alveolar fraction) must be respected under consideration of national provisions.

Exposure controls

Appropriate engineering controls. Provide sufficient ventilation.

Protective and hygiene measures

When using do not eat, drink or smoke. Wash hands before breaks and after work. Remove contaminated, saturated clothing immediately.

Eye/face protection

Wear tightly fitting safety goggles. (DIN EN 166)

Hand protection

Tested protective gloves must be worn (DIN EN 374)

The quality of the protective gloves resistant to chemicals must be chosen as a function of the specific working place

concentration and quantity of hazardous substances. Due to missing tests no material recommendation can be given.

Skin protection

Wear suitable chemical resistant protective clothing. Choose suitable personal protection equipment dependent on substance concentration and amount specific for workplace. Chemical resistance should be clarified with the supplier.

Respiratory protection

The selection of appropriate respiratory protection systems should be determined on a case by case base

depending on the exposure conditions. At exposure to dust or mist respiratory equipment with particle filter P3 (EN 143) recommended.

Maintenance, testing and change of the filter cartridges must be performed following the recommendations of the supplier.

Environmental exposure controls

Do not allow to enter into soil/subsoil.

Do not allow to enter into surface water or drains.
