First-aid measures

General information:
Ensure that medical personnel are aware of the material(s) involved, and take precautions to protect themselves. Wash contaminated clothing before reuse.

Description of first aid measures:
Inhalation: Remove victim to fresh air and keep at rest in a position comfortable for breathing. Get medical attention immediately.
Skin contact: Take off immediately all contaminated clothing. Wash skin with soap and water. For minor skin contact, avoid spreading material on unaffected skin. Get medical attention immediately.
Eye contact: Rinse immediately with plenty of water for at least 15 minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Get medical attention immediately.
Ingestion Rinse mouth. Do not induce vomiting. Get medical attention immediately.

Most important symptoms and effects, both acute and delayed:
Burning pain and severe corrosive skin damage. Causes serious eye damage. Symptoms may include stinging, tearing, redness, swelling, and blurred vision. Permanent eye damage including blindness could result.

Indication of any immediate medical attention and special treatment needed:
Treat symptomatically

Fire-fighting measures

General fire hazards No unusual fire or explosion hazards noted.

Extinguishing media:
Suitable extinguishing media
Larger fires: Medium expansion AFFF foam.
Small fires: Medium expansion AFFF foam, dry chemical or carbon dioxide.

Unsuitable extinguishing media
Water

Special hazards arising from the substance or mixture:
Water reactive material. By heating and fire, harmful vapours/gases may be formed. Hydrogen chloride. (corrosive)

Advice for firefighters:
Special protective equipment for firefighters: Firefighters must use standard protective equipment including flame retardant coat, helmet, gloves, rubber boots, and self-contained breathing apparatus.
Special fire fighting procedures: Move containers from fire area if you can do so without risk. Do not get water inside container. Water runoff can cause environmental damage.

Accidental release measures

Personal precautions, protective equipment and emergency procedures:
For non-emergency personnel: Keep unnecessary personnel away.
For emergency responders: Local authorities should be advised if significant spillages cannot be contained. Do not touch or walk through spilled material. Ensure adequate ventilation.Wear appropriate personal protective equipment.

Environmental precautions: Prevent further leakage or spillage if safe to do so. Avoid release to the environment.

Methods and material for containment and cleaning up:

Eliminate sources of ignition.

Large Spills: Stop the flow of material, if this is without risk. Dam the spilled material, where this is possible. Cover with DRY earth, DRY sand or other non-combustible material followed with plastic sheet to minimise spreading or contact with rain. Do not get water on spilled substance or inside containers. Prevent entry into waterways, sewer, basements or confined areas.
Small Spills: Wipe up with absorbent material (e.g. cloth, fleece). Clean surface thoroughly to remove residual contamination.

Never return spills in original containers for re-use.

For personal protection and waste disposal, see below.

Handling and storage

Precautions for safe handling:
This product reacts with water, moisture, or humid air to evolve following compounds: hydrogen chloride.
Provide adequate ventilation. Use only outdoors or in a dry well-ventilated area. Do not allow water to get into container because of violent reaction and possible flash fire. Wash hands thoroughly after handling. Avoid release to the environment. Do not empty into drains. Do not breathe mist or vapour. Do not get this material in contact with eyes. Do not get this material in contact with skin. Avoid prolonged exposure.

Conditions for safe storage, including any incompatibilities
Never allow product to get in contact with water during storage. Store locked up. Keep container tightly closed. Keep out of the reach of children. Store in a cool, dry place out of direct sunlight. Store in a building without sprinklers. Keep in original container.
