According to Regulation 1994 OSHA Hazard Communication Standard; 29 CFR Part 1910.1200 Emergency overview
WARNING:
May cause sensitization by skin contact. HARMFUL IF INHALED.
CONTAINS ISOCYANATES. INHALATION OF ISOCYANATE MISTS OR VAPORS MAY CAUSE RESPIRATORY IRRITATION, BREATHLESSNESS, CHEST DISCOMFORT AND REDUCED PULMONARY FUNCTION. OVEREXPOSURE WELL ABOVE THE PEL MAY RESULT IN BRONCHITIS, BRONCHIAL SPASMS AND PULMONARY EDEMA. LONG-TERM EXPOSURE TO ISOCYANATES HAS BEEN REPORTED TO CAUSE LUNG DAMAGE, INCLUDING REDUCED LUNG FUNCTION WHICH MAY BE PERMANENT. ACUTE OR CHRONIC OVEREXPOSURE TO ISOCYANATES MAY CAUSE SENSITIZATION IN SOME INDIVIDUALS, RESULTING IN ALLERGIC RESPIRATORY REACTIONS INCLUDING WHEEZING, SHORTNESS OF BREATH AND DIFFICULTY BREATHING. ANIMAL TESTS INDICATE THAT SKIN CONTACT MAY PLAY A ROLE IN CAUSING RESPIRATORY SENSITIZATION.
Use with local exhaust ventilation. Wear protective clothing. Wear a full face shield if a splashing hazard exists.

Description of first aid measures
General advice:
Immediately remove contaminated clothing.
If inhaled:
Remove to fresh air. If breathing is difficult, give oxygen. If symptoms persist, call a physician.
If on skin:
Wash off immediately with soap and plenty of water while removing all contaminated clothes and shoes. If symptoms persist, call a physician.
If in eyes:
Immediately flush with plenty of water. After initial flushing, remove any contact lenses and continue flushing for at least 15 minutes. Keep eye wide open while rinsing. If symptoms persist, call a physician
If swallowed:
Immediately rinse mouth and then drink plenty of water, do not induce vomiting, seek medical attention. Never induce vomiting or give anything by mouth if the victim is unconscious or having convulsions.
Most important symptoms and effects, both acute and delayed:
Symptoms: The most important known symptoms and effects are described in the labelling (see section 2) and/or in section 11., Further important symptoms and effects are so far not known.
Note to physician

5. Fire-Fighting Measures
Extinguishing media
Suitable extinguishing media: dry powder, foam
Special hazards arising from the substance or mixture
Hazards during fire-fighting: harmful vapors
Advice forfire-fighters
Protective equipment for fire-fighting:
Firefighters should be equipped with self-contained breathing apparatus and turn-out gear.
Further Information
The degree of risk is governed by the burning substance and the fire conditions. Contaminated extinguishing water must be disposed of in accordance with official regulations.
6. Accidental release measures
Personal precautions, protective equipment and emergency procedures
Use personal protective clothing.
Environmental precautions
Contain contaminated water/firefighting water. Do not discharge into drains/surface waters/groundwater.
Methods and material for containment and cleaning up
Spills should be contained, solidified, and placed in suitable containers for disposal.
7. Handling and Storage
Precautions for safe handling
Protection against fire and explosion:
Take precautionary measures against static discharges.
Conditions for safe storage, including any incompatibilities
Further information on storage conditions: Keep container tightly closed and dry; store in a cool place. Storage stability:
If moisture enters isocyanate containers, CO2 forms and pressure builds up.
8. Exposure Controls/Personal Protection
Engineering Measures

Provide natural or explosion-proof ventilation adequate to ensure concentrations are kept below exposure limits
Personal protectiveequipment Respiratory protection:
Wear respiratory protection if ventilation is inadequate. Wear a NIOSH-certified (or equivalent) organic
vapor/particulate respirator. Do not exceed the maximum use concentration for the respirator face piece/cartridge combination. For emergency or non-routine, high exposure situations, use a NIOSH-certified full face piece pressure demand self- contained breathing apparatus (SCBA) or a full face piece pressure demand supplied-air respirator (SAR) with escape provisions.
Hand protection:
Chemical resistant protective gloves
Eye protection:
Tightly fitting safety goggles (chemical goggles). Wear face shield if splashing hazard exists
General safety and hygienemeasures:
Handle in accordance with good industrial hygiene and safety practice. Wearing of closed work clothing is required additionally to the stated personal protection equipment. Avoid inhalation of mists. Contact with eyes and skin must be avoided.
