First-aid measures

Eye contact.

Get medical attention immediately.  Call a poison center or physician.  Immediately flush eyes with plenty of water, occasionally lifting the upper and lower eyelids.  Check for and remove any contact lenses.  Continue to rinse for at least 10 minutes.  Chemical burns must be treated promptly by a physician.

Inhalation.

Get medical attention immediately.  Call a poison center or physician.  Remove victim to fresh air and keep at rest in a position comfortable for breathing.  If it is suspected that fumes are still present, the rescuer should wear an appropriate mask or self-contained breathing apparatus.  If not breathing, if breathing is irregular or if respiratory arrest occurs, provide artificial respiration or oxygen by trained personnel.  It may be dangerous to the person providing aid to give mouth-to-mouth resuscitation.  If unconscious, place in recovery position and get medical attention immediately.  Maintain an open airway.  Loosen tight clothing such as a collar, tie, belt or waistband.

SkinGet medical attention immediately.  Call a poison center or physician.  Flush contaminated skin with plenty of water.  Remove contaminated clothing and shoes.  Wash contaminated clothing thoroughly with water before removing it, or wear gloves.  Continue to rinse for at least 10 minutes.  Chemical burns must be treated promptly by a physician.  Wash clothing before reuse.  Clean shoes thoroughly before reuse. contact.

Ingestion

Get medical attention immediately.  Call a poison center or physician.  Wash out mouth with water.  Remove dentures if any.  Remove victim to fresh air and keep at rest in a position comfortable for breathing.  If material has been swallowed and the exposed person is conscious, give small quantities of water to drink.  Stop if the exposed person feels sick as vomiting may be dangerous.  Do not induce vomiting unless directed to do so by medical personnel.  If vomiting occurs, the head should be kept low so that vomit does not enter the lungs.  Chemical burns must be treated promptly by a physician.  Never give anything by mouth to an unconscious person.  If unconscious, place in recovery position and get medical attention immediately.  Maintain an open airway.  Loosen tight clothing such as a collar, tie, belt or waistband.

Protection of first-aiders.

No action shall be taken involving any personal risk or without suitable training.  If it is suspected that fumes are still present, the rescuer should wear an appropriate mask or self-contained breathing apparatus.  It may be dangerous to the person providing aid to give mouth-to-mouth resuscitation.  Wash contaminated clothing thoroughly with water before removing it, or wear gloves.

No action shall be taken involving any personal risk or without suitable training.  If it is suspected that fumes are still present, the rescuer should wear an appropriate mask or self-contained breathing apparatus.  It may be dangerous to the person providing aid to give mouth-to-mouth resuscitation.  Wash contaminated clothing thoroughly with water before removing it, or wear gloves.

Fire-fighting measures

Extinguishing media.

Use an extinguishing agent suitable for the surrounding fire.  

Special hazards arising from the substance.

In a fire or if heated, a pressure increase will occur and the container may burst. Decomposition products may include the following materials: carbon dioxide, carbon monoxide.

Advice for firefighters

Promptly isolate the scene by removing all persons from the vicinity of the incident if there is a fire.  No action shall be taken involving any personal risk or without suitable training. Fire-fighters should wear appropriate protective equipment and self-contained breathing apparatus (SCBA) with a full face-piece operated in positive pressure mode.  Clothing for fire-fighters (including helmets, protective boots and gloves) conforming to European standard EN 469 will provide a basic level of protection for chemical incidents.

Accidental release measures

Personal precautions, protective equipment adn emergency procedures.

For non-emergency personnel. No action shall be taken involving any personal risk or without suitable training.  Evacuate surrounding areas.  Keep unnecessary and unprotected personnel from entering.  Do not touch or walk through spilled material.  Do not breathe vapor or mist.  Provide adequate ventilation.  Wear appropriate respirator when ventilation is inadequate.  Put on appropriate personal protective equipment.

For emergency responders.If specialized clothing is required to deal with the spillage, take note of any information in Section 8 on suitable and unsuitable materials.  See also the information in "For non-emergency personnel".

Environmental precautions.

Avoid dispersal of spilled material and runoff and contact with soil, waterways, drains and sewers.  Inform the relevant authorities if the product has caused environmental pollution (sewers, waterways, soil or air).

Methods and material for cotainment and cleaning up.

Small spill. Stop leak if without risk.  Move containers from spill area.  Dilute with water and mop up if water-soluble.  Alternatively, or if water-insoluble, absorb with an inert dry material and place in an appropriate waste disposal container.  Dispose of via a licensed waste disposal contractor.

Large spill.  Stop leak if without risk.  Move containers from spill area.  Approach release from upwind.  Prevent entry into sewers, water courses, basements or confined areas.  Wash spillages into an effluent treatment plant or proceed as follows.  Contain and collect spillage with non-combustible, absorbent material e.g. sand, earth, vermiculite or diatomaceous earth and place in container for disposal according to local regulations.  Dispose of via a licensed waste disposal contractor.  Contaminated absorbent material may pose the same hazard as the spilled product.

Handling and storage

Precautions for safe handling.

Put on appropriate personal protective equipment.  Do not get in eyes or on skin or clothing.  Do not breathe vapor or mist.  Do not ingest.  If during normal use the material presents a respiratory hazard, use only with adequate ventilation or wear appropriate respirator.  Keep in the original container or an approved alternative made from a compatible material, kept tightly closed when not in use.  Empty containers retain product residue and can be hazardous.  Do not reuse container.

Eating, drinking and smoking should be prohibited in areas where this material is handled, stored and processed.  Workers should wash hands and face before eating, drinking and smoking.  Remove contaminated clothing and protective equipment before entering eating areas.

Conditions for safe storage.

Store in accordance with local regulations.  Store in original container protected from direct sunlight in a dry, cool and well-ventilated area, away from incompatible materials and food and drink.  Store locked up.  Keep container tightly closed and sealed until ready for use.  Containers that have been opened must be carefully resealed and kept upright to prevent leakage.  Do not store in unlabeled containers.  Use appropriate containment to avoid environmental contamination.
