weight: 360 g/mol Chemical family: aromatic isocyanates Synonyms: POLYMETHYLENE POLYPHENYLISOCYANATE 2. Composition/information on ingredients CAS Number Content (W/W) Chemical name
101-68-8 38.0 % Diphenylmethane-4,4'-diisocyanate (MDI) 26447-40-5 < 10.0 % MDI Mixed Isomers 9016-87-9 < 55.0 % P-MDI 3. Hazard identification Emergency overview CAUTION: CONTAINS DIPHENYLMETHANE
DIISOCYANATE (CAS No. 101-68-8). INHALATION OF MDI 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 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. Potential health effects Primary routes of exposure Routes of entry for solids and liquids include eye and skin contact, ingestion and inhalation.
Routes of entry for gases include inhalation and eye contact. Skin contact may be a route of entry for liquified gases. Acute toxicity: Information on: MDI Inhalation of MDI vapors may
cause irritation of the mucous membranes of the nose, throat or trachea, breathlessness, chest discomfort, difficult breathing and reduced pulmonary function. Airboorn overexposure well
above the PEL may result additionally in eye irritation, headache, chemical bronchitis, asthma-like findings or pulmonary edema. Isocyanates have also been reported to
Safety data sheet ELASTOSPRAY® 8000A ISOCYANATE Revision date : 2008/03/17 Page: 2/7 Version: 5.6 (30232235/MDS_GEN_US/EN) cause hypersensitivity pneumonitis, which is characterized
by flu-like symptoms, the onset of which may bedelayed. Gastrointestinal symptoms include nausea, vomiting and abdominal pain. Irritation: Information on: Diisocyanates Eye contact with
isocyanates may result in conjunctival irritation and mild corneal opacity. Skin contact may result in dermatitis, either irritative or allergic. Repeated dose toxicity: Information
on: MDI Results from a lifetime inhalation study in rats indicate that MDI aerosol was carcinogenic at 6 mg/m3, the highest dose tested. This is well above the recommended TLV of 5 ppb
(0.05 mg/m3). Only irritation was noted at the lower concentration of 0.2 and 1 mg/m3. No birth defects or teratogenic effects were reported in a teratology study with rats exposed to
1, 4, and 12 mg/m3 polymeric MDI for 6 hr/day on days 6-15 of gestation. Embryotoxicity and fetotoxicity was reported at the top dose in the presence of maternal toxicity. Information
on: Isocyanates As a result of previous repeated overexposures or a single large dose, certain individuals will develop isocyanate sensitization (chemical asthma) which will cause them
to react to a later exposure to isocyanate at levels well below the PEL/TLV. These symptoms, which include chest tightness, wheezing, cough, shortness of breath, or asthmatic attack,
could be immediate or delayed up to several hours after exposure. Similar to many non-specific asthmatic responses, there are reports that once sensitized an individual can experience
these symptoms upon exposure to dust, cold air, or other irritants. This increased lung sensitivity can persist for weeks and in severe cases for several years. Chronic overexposure
to isocyanates has also been reported to cause lung damage, including a decrease in lung function, which may be permanent. Sensitization may be either temporary or permanent. Prolonged
contact can cause reddening, swelling, rash, scaling, or blistering. In those who have developed a skin sensitization, these symptoms can develop as a result of contact with very small
amounts of liquid material, or even as a result of vapor-only exposure. Medical conditions aggravated by 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. Medical supervision of all employees who handle or come into contact with isocyanates
is recommended. Contact may aggravate pulmonary disorders. Persons with history of respiratory disease or hypersensitivity should not be exposed to this product. Preemployment and periodic
medical examinations with respiratory function tests (FEV, FVC as a minimum) are suggested. An animal study indicated that MDI may induce respiratory hypersensitivity following dermal
exposure. 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. 4. First-aid measures General advice:
Remove contaminated clothing. 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.
Safety data sheet ELASTOSPRAY® 8000A ISOCYANATE Revision date : 2008/03/17 Page: 3/7 Version: 5.6 (30232235/MDS_GEN_US/EN) 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 Hazards:
Symptoms can appear later. Antidote: Specific antidotes or neutralizers to isocyanates do not exist. Treatment: Treatment should be supportive and based on the judgement of the physician
in response to the reaction of the patient. 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. 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: Absorb isocyanate with suitable
absorbent material (see § 40 CFR, sections 260, 264 and 265 for further information). 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 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: 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.
