First-aid measures

Inhalation:
Get medical attention immediately. Move exposed person to fresh air. If it is suspected that fumes are still present, the rescuer should wear an appropriate mask or self-contained breathing apparatus. Keep person warm and at rest. 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. In case of inhalation of decomposition products in a fire, symptoms may be delayed. The exposed person may need to be kept under medical surveillance for 48 hours. In the event of any complaints or symptoms, avoid further exposure.

Ingestion:
Get medical attention immediately. Wash out mouth with water. Move exposed person to fresh air. Keep person warm and at rest. 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.

Skin contact:
Get medical attention immediately. Remove contaminated clothing and shoes. Wash the skin immediately with plenty of soap and water; cleaning immediately with polyethyleneglycol 400 and washing subsequently with plenty of soap and water would be more effective. Wash skin immediately with plenty of soap and water even when contact with the product is suspected. Chemical burns must be treated promptly by a physician. Wash clothing before reuse. Clean shoes thoroughly before reuse.

Eye contact:
Get medical attention immediately. 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.

Notes to physician:
Basic aid, decontamination, symptomatic treatment. Treat with a corticoid metered aerosol depending on the amount inhaled. If appropriate symptoms occur or inhalation of large quantities is suspected, administer cortisone intravenously in addition Medical surveillance for at least 48 hours.

Fire-fighting measures

Extinguishing media:
Suitable: In case of fire, use water spray (fog), foam, dry chemical or CO2.
Not suitable: Do not use water jet.

Special exposure hazards:
Highly flammable liquid. In a fire or if heated, a pressure increase will occur and the container may burst, with the risk of a subsequent explosion. Runoff to sewer may create fire or explosion hazard.
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. Move containers from fire area if this can be done without risk. Use water spray to keep fire-exposed containers cool. This material is harmful to aquatic organisms. Fire water contaminated with this material must be contained and prevented from being discharged to any waterway, sewer or drain.

Hazardous combustion products:
Decomposition products may include the following materials:
carbon oxides
nitrogen oxide
hydrogen cyanade

Special protective equipment for fire-fighters:
Fire-fighters should wear appropriate protective equipment and selfcontained breathing apparatus (SCBA) with a full face-piece operated in positive pressure mode.

Remark:
The vapours are heavier than air and creep at ground level. If they are ignited, the flame may cover large distances.

Accidental release measures

Personal precautions:
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. Shut off all ignition sources. No flares, smoking or flames in hazard area. Avoid breathing vapor or mist. Provide adequate ventilation. Put on appropriate personal protective equipment.

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). Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment.

Large spill:
Stop leak if without risk. Prevent entry into sewers, water courses, basements or confined areas. Use spark-proof tools and explosionproof equipment. Collect spillage. Absorb with an inert material and place in an appropriate waste disposal container. Do not firmly seal waste containers (risk of CO2 generation!). Dispose of via a licensed waste disposal contractor. Carefully decompose residues with an aqueous ammonia solution. Note: see section 1 for emergency contact information and section 13 for waste disposal. Contaminated absorbent material may pose the same hazard as the spilled product.

Small spill:
Stop leak if without risk. Use spark-proof tools and explosion-proof equipment. Take up with a moist, liquid-binding material (e.g. sand, sawdust or chemical binder based on hydrated calcium silicate) and treat carefully with diluted ammonia solution. Do not firmly seal waste containers (risk of CO2 generation!). Once the reaction is fully complete, pass on to disposal facilities. Dispose of via a licensed waste disposal contractor. Contaminated absorbent material may pose the same hazard as the spilled product.
