Potential Health Effects

Eye Contact: May cause moderate eye irritation. May cause slight temporary corneal injury. 

Skin Contact: Prolonged contact may cause slight skin irritation with local redness. May stain skin. 

Skin Absorption: Prolonged skin contact is unlikely to result in absorption of harmful amounts. 

Skin Sensitization: Skin contact may cause an allergic skin reaction. Animal studies have shown that 

skin contact with isocyanates may play a role in respiratory sensitization. 

Inhalation: At room temperature, vapors are minimal due to low volatility. However, certain 

operations may generate vapor or mist concentrations sufficient to cause respiratory irritation and 

other adverse effects. Such operations include those in which the material is heated, sprayed or 

otherwise mechanically dispersed such as drumming, venting or pumping. Excessive exposure may 

cause irritation to upper respiratory tract (nose and throat) and lungs. May cause pulmonary edema 

(fluid in the lungs.) Effects may be delayed. Decreased lung function has been associated with 

overexposure to isocyanates. 

Respiratory Sensitization: May cause allergic respiratory response. MDI concentrations below the 

exposure guidelines may cause allergic respiratory reactions in individuals already sensitized. 

Asthma-like symptoms may include coughing, difficult breathing and a feeling of tightness in the chest. 

Occasionally, breathing difficulties may be life threatening. 

Ingestion: Low toxicity if swallowed. Small amounts swallowed incidentally as a result of normal 

handling operations are not likely to cause injury; however, swallowing larger amounts may cause 

injury. 

Aspiration hazard: Based on physical properties, not likely to be an aspiration hazard. 

Effects of Repeated Exposure: Tissue injury in the upper respiratory tract and lungs has been 

observed in laboratory animals after repeated excessive exposures to MDI/polymeric MDI aerosols. 

Cancer Information: Lung tumors have been observed in laboratory animals exposed to respirable 

aerosol droplets of MDI/Polymeric MDI (6 mg/m3) for their lifetime. Tumors occurred concurrently with 

respiratory irritation and lung injury. Current exposure guidelines are expected to protect against these 

effects reported for MDI. 

Birth Defects/Developmental Effects: In laboratory animals, MDI/polymeric MDI did not cause birth 

defects; other fetal effects occurred only at high doses which were toxic to the mother.

4. First-aid measures 

Description of first aid measures

General advice: First Aid responders should pay attention to self-protection and use the 

recommended protective clothing (chemical resistant gloves, splash protection). If potential for 

exposure exists refer to Section 8 for specific personal protective equipment. 

Inhalation: Move person to fresh air. If not breathing, give artificial respiration; if by mouth to mouth 

use rescuer protection (pocket mask, etc). If breathing is difficult, oxygen should be administered by 

qualified personnel. Call a physician or transport to a medical facility. 

Skin Contact: Remove material from skin immediately by washing with soap and plenty of water. 

Remove contaminated clothing and shoes while washing. Seek medical attention if irritation persists. 

Wash clothing before reuse. An MDI skin decontamination study demonstrated that cleaning very 

soon after exposure is important, and that a polyglycol-based skin cleanser or corn oil may be more 

effective than soap and water. Discard items which cannot be decontaminated, including leather 

articles such as shoes, belts and watchbands. Suitable emergency safety shower facility should be 

available in work area. 

Eye Contact: Immediately flush eyes with water; remove contact lenses, if present, after the first 5 

minutes, then continue flushing eyes for at least 15 minutes. Obtain medical attention without delay, 

3. Composition Information

preferably from an ophthalmologist. Suitable emergency eye wash facility should be immediately 

available. 

Ingestion: If swallowed, seek medical attention. Do not induce vomiting unless directed to do so by 

medical personnel. 

Most important symptoms and effects, both acute and delayed

Aside from the information found under Description of first aid measures (above) and Indication of 

immediate medical attention and special treatment needed (below), no additional symptoms and 

effects are anticipated.

Indication of immediate medical attention and special treatment needed

Maintain adequate ventilation and oxygenation of the patient. May cause respiratory sensitization or 

asthma-like symptoms. Bronchodilators, expectorants and antitussives may be of help. Treat 

bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids. Respiratory 

symptoms, including pulmonary edema, may be delayed. Persons receiving significant exposure 

should be observed 24-48 hours for signs of respiratory distress. If you are sensitized to 

diisocyanates, consult your physician regarding working with other respiratory irritants or sensitizers. 

Treatment of exposure should be directed at the control of symptoms and the clinical condition of the 

patient. 

Excessive exposure may aggravate preexisting asthma and other respiratory disorders (e.g. 

emphysema, bronchitis, reactive airways dysfunction syndrome). 

5. Fire Fighting Measures 

Suitable extinguishing media

Water fog or fine spray. Dry chemical fire extinguishers. Carbon dioxide fire extinguishers. Foam. 

Alcohol resistant foams (ATC type) are preferred. General purpose synthetic foams (including AFFF) 

or protein foams may function, but will be less effective. 

Extinguishing Media to Avoid: Do not use direct water stream. May spread fire. 

Special hazards arising from the substance or mixture

Hazardous Combustion Products: During a fire, smoke may contain the original material in addition 

to combustion products of varying composition which may be toxic and/or irritating. Combustion 

products may include and are not limited to: Nitrogen oxides. Isocyanates. Hydrogen cyanide. 

Carbon monoxide. Carbon dioxide. 

Unusual Fire and Explosion Hazards: Product reacts with water. Reaction may produce heat and/or 

gases. This reaction may be violent. Container may rupture from gas generation in a fire situation. 

Violent steam generation or eruption may occur upon application of direct water stream to hot liquids. 

Dense smoke is produced when product burns. 

Advice for firefighters

Fire Fighting Procedures: Keep people away. Isolate fire and deny unnecessary entry. Stay 

upwind. Keep out of low areas where gases (fumes) can accumulate. Water is not recommended, but 

may be applied in large quantities as a fine spray when other extinguishing agents are not available. 

Do not use direct water stream. May spread fire. Fight fire from protected location or safe distance. 

Consider the use of unmanned hose holders or monitor nozzles. Immediately withdraw all personnel 

from the area in case of rising sound from venting safety device or discoloration of the container. 

Move container from fire area if this is possible without hazard. Use water spray to cool fire-exposed 

containers and fire-affected zone until fire is out. Contain fire water run-off if possible. Fire water runoff, if not contained, may cause environmental damage. Review the "Accidental Release Measures" 

and the "Ecological Information" sections of this (M)SDS. 

Special Protective Equipment for Firefighters: Wear positive-pressure self-contained breathing 

apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet, coat, trousers, 

boots, and gloves). Avoid contact with this material during fire fighting operations. If contact is likely, 

change to full chemical resistant fire fighting clothing with self-contained breathing apparatus. If this is 

not available, wear full chemical resistant clothing with self-contained breathing apparatus and fight fire

from a remote location. For protective equipment in post-fire or non-fire clean-up situations, refer to 

the relevant sections. 

6. Accidental Release Measures 

Personal precautions, protective equipment and emergency procedures: Isolate area. Keep 

unnecessary and unprotected personnel from entering the area. Keep personnel out of low areas. 

Keep upwind of spill. Spilled material may cause a slipping hazard. Ventilate area of leak or spill. If 

available, use foam to smother or suppress. Refer to Section 7, Handling, for additional precautionary 

measures. See Section 10 for more specific information. Use appropriate safety equipment. For 

additional information, refer to Section 8, Exposure Controls and Personal Protection. 

Environmental precautions: Prevent from entering into soil, ditches, sewers, waterways and/or 

groundwater. See Section 12, Ecological Information. 

Methods and materials for containment and cleaning up: Contain spilled material if possible.

Personal Protection

Eye/Face Protection: Use chemical goggles. 

Skin Protection: Use protective clothing chemically resistant to this material. Selection of specific 

items such as face shield, boots, apron, or full body suit will depend on the task. 

Hand protection: Use gloves chemically resistant to this material. Examples of preferred 

glove barrier materials include: Butyl rubber. Polyethylene. Chlorinated polyethylene. Ethyl 

vinyl alcohol laminate ("EVAL"). Examples of acceptable glove barrier materials include: 

Viton. Neoprene. Polyvinyl chloride ("PVC" or "vinyl"). Nitrile/butadiene rubber ("nitrile" or 

"NBR"). NOTICE: The selection of a specific glove for a particular application and duration of 

use in a workplace should also take into account all relevant workplace factors such as, but 

not limited to: Other chemicals which may be handled, physical requirements (cut/puncture 

protection, dexterity, thermal protection), potential body reactions to glove materials, as well as 

the instructions/specifications provided by the glove supplier. 

Respiratory Protection: Atmospheric levels should be maintained below the exposure guideline. 

When atmospheric levels may exceed the exposure guideline, use an approved air-purifying respirator 

equipped with an organic vapor sorbent and a particle filter. For situations where the atmospheric 

levels may exceed the level for which an air-purifying respirator is effective, use a positive-pressure 

air-supplying respirator (air line or self-contained breathing apparatus). For emergency response or 

for situations where the atmospheric level is unknown, use an approved positive-pressure selfcontained breathing apparatus or positive-pressure air line with auxiliary self-contained air supply. The 

following should be effective types of air-purifying respirators: Organic vapor cartridge with a 

particulate pre-filter. 

Ingestion: Use good personal hygiene. Do not consume or store food in the work area. Wash hands 

before smoking or eating. 

Engineering Controls

Ventilation: Use only with adequate ventilation. Provide general and/or local exhaust ventilation to 

control airborne levels below the exposure guidelines. Exhaust systems should be designed to move 

the air away from the source of vapor/aerosol generation and people working at this point. The odor 

and irritancy of this material are inadequate to warn of excessive exposure. Local exhaust ventilation 

may be necessary for some operations.

10. Stability and Reactivity 

Reactivity

Diisocyanates react with many materials and the rate of reaction increases with temperature as well as 

increased contact; these reactions can become violent. Contact is increased by stirring or if the other 

material mixes with the diisocyanate., Diisocyanates are not soluble in water and sink to the bottom, 

but react slowly at the interface. The reaction forms carbon dioxide gas and a layer of solid polyurea., 

Reaction with water will generate carbon dioxide and heat. 

Chemical stability

Stable under recommended storage conditions. See Storage, Section 7. 

Possibility of hazardous reactions

Can occur. Elevated temperatures can cause hazardous polymerization. Polymerization can be 

catalyzed by: Strong bases. Water. 

Conditions to Avoid: Exposure to elevated temperatures can cause product to decompose. 

Generation of gas during decomposition can cause pressure in closed systems. Pressure build-up 

can be rapid. Avoid moisture. Material reacts slowly with water, releasing carbon dioxide which can 

cause pressure buildup and rupture of closed containers. Elevated temperatures accelerate this 

reaction. 

Incompatible Materials: Avoid contact with: Acids. Alcohols. Amines. Water. Ammonia. Bases. 

Metal compounds. Moist air. Strong oxidizers. Diisocyanates react with many materials and the rate 

of reaction increases with temperature as well as increased contact; these reactions can become 

violent. Contact is increased by stirring or if the other material mixes with the diisocyanate. 

Diisocyanates are not soluble in water and sink to the bottom, but react slowly at the interface. The 

reaction forms carbon dioxide gas and a layer of solid polyurea. Reaction with water will generate 

carbon dioxide and heat. Avoid contact with metals such as: Aluminum. Zinc. Brass. Tin. Copper. 

Galvanized metals. Avoid contact with absorbent materials such as: Moist organic absorbents. Avoid 

unintended contact with polyols. The reaction of polyols and isocyanates generate heat. 

Hazardous decomposition products

Decomposition products depend upon temperature, air supply and the presence of other materials. 

Gases are released during decomposition.
