SECTION 2: Hazards identification

HMIS Classification Emergency overview Irritating to eyes, respiratory system and skin. May cause sensitization by inhalation.

Potential health effects

Acute toxicity: May cause sensitization by inhalation. Irritation: Irritating to eyes, respiratory system and skin.

Medical Conditions Generally Aggravated by Exposure

overexposure The isocyanate component is a respiratory sensitizer. It may cause allergic reaction leading to asthma-like spasms of the bronchial tubes and difficulty in breathing. Persons with asthmatic conditions, chronic bronchitis, other chronic respiratory diseases, recurrent eczema or pulmonary sensitization should be excluded from working with isocyanates. Once a person is diagnosed as having pulmonary sensitization (allergic asthma) to isocyanates, further exposure is not recommended. An animal study indicated that MDI may induce respiratory hypersensitivity following dermal exposure. 4. First-aid measures If inhaled: Remove the affected individual into fresh air and keep the person calm. Assist in breathing if necessary. Immediate medical attention required. If on skin: Wash affected areas thoroughly with soap and water. If irritation develops, seek medical attention. If in eyes: In case of contact with the eyes, rinse immediately for at least 15 minutes with plenty of water. Immediate medical attention required. If swallowed: Rinse mouth and then drink plenty of water. Do not induce vomiting. Never induce vomiting or give anything by mouth if the victim is unconscious or having convulsions. Immediate medical attention required. Note to physician Symptoms can appear later. Treatment: Treat according to symptoms (decontamination, vital functions), no known specific antidote, administer corticosteroid dose aerosol to prevent pulmonary odema. 5. Fire-fighting measures Flash point: 220 °C (open cup) Autoignition: No data available. Suitable extinguishing media: water, dry extinguishing media, carbon dioxide, foam Hazards during fire-fighting: nitrous gases, fumes/smoke, isocyanate, vapour Protective equipment for fire-fighting: Firefighters should be equipped with self-contained breathing apparatus and turn-out gear.

Further information

Keep containers cool by spraying with water if exposed to fire. Dispose of fire debris and contaminated extinguishing water in accordance with official regulations. 6. Accidental release measures Personal precautions: Clear area. Ensure adequate ventilation. Wear suitable personal protective clothing and equipment. Environmental precautions: Do not discharge into drains/surface waters/groundwater. Cleanup: Dike spillage. For small amounts: Pick up with suitable absorbent material. Shovel into open container. Do not make container pressure tight. Move container to a well-ventilated area (outside). Spill area can be decontaminated with the following recommended decontamination solution: Mixture of 90 % water, 8 % concentrated ammonia, 2 % detergent. Add at a 10 to 1 ratio. Allow to stand for at least 48 hours to allow escape of evolved carbon dioxide. For large amounts: If temporary control of isocyanate vapor is required, a blanket of protein foam or other suitable foam (available from most fire departments) may be placed over the spill. Transfer as much liquid as possible via pump or vacuum device into closed but not sealed containers for disposal. For residues The following measures should be taken for final cleanup Wash down spill area with decontamination solution. Allow solution to stand for at least 10 minutes. 7. Handling and storage Handling General advice: Mix thoroughly before use. If bulging of drum occurs, transfer to well ventilated area, puncture to relieve pressure, open vent and let stand for 48 hours before resealing. Protection against fire and explosion: No explosion proofing necessary.

Storage

General advice: Formation of CO2 and build up of pressure possible. Keep container tightly closed and in a well-ventilated place. Outage of containers should be filled with dry inert gas at atmospheric pressure to avoid reaction with moisture. Storage incompatibility: General: Segregate from bases. Storage stability: Protect against moisture. 8. Exposure controls and personal protection Advice on system design: Provide local exhaust ventilation to maintain recommended P.E.L. Personal protective equipment Respiratory protection: Wear a NIOSH-certified self-contained breathing apparatus or full face supplied air respirator. Hand protection: Chemical resistant protective gloves (EN 374), Suitable materials, Rubber gloves, Plastic gloves Eye protection: Tightly fitting safety goggles (chemical goggles). Wear face shield if splashing hazard exists. Body protection: safety shoes (f.e. according to EN 20346) General safety and hygiene measures: Wear protective clothing as necessary to prevent contact. No eating, drinking, smoking or tobacco use at the place of work. Take off immediately all contaminated clothing. Hands and/or face should be washed before breaks and at the end of the shift. At the end of the shift the skin should be cleaned and skin-care agents applied. 9. Physical and chemical properties Form: liquid Odour: faint odour, aromatic Odour threshold: No data available. Colour: dark brown pH value: No data available. Freezing point: 3 °C ( 1 ATM) Boiling point: 200 °C ( 5 mmHg) Vapour pressure: < 0.00001 mmHg ( 20 °C) Density: 1.22 g/cm3 ( 20 °C) Relative density: 1.22 ( 25 °C) Bulk density: 10.16 lb/USg Viscosity, dynamic: 200 mPa.s ( 20 °C) Miscibility with water: Reacts with water. 10. Stability and reactivity Conditions to avoid: Avoid moisture. Substances to avoid: acids, alcohols, amines, water, Alkalines Hazardous reactions: On contact with water, gaseous decomposition products are formed, which cause build-up of pressure in tightly closed containers. Risk of bursting. Reacts with substances which contain active hydrogen. Decomposition products: Hazardous decomposition products: carbon monoxide, hydrogen cyanide, nitrogen oxides, aromatic isocyanates, gases/vapours Thermal decomposition: > 230 °C Corrosion to metals: No corrosive effect on metal.
