General Fire Hazards
MDI vapor and other gases may be generated by thermal decomposition. At temperatures greater than 160癈/320?MDI can

reaction of MDI with water, which releases carbon dioxide and makes explosive rupture of closed containers possible.
NFPA Ratings:
Health = 3* Fire = 1 Reactivity = 1
*=chronic health hazard
Hazardous Combustion Products
Carbon monoxide, carbon dioxide, halogenated hydrocarbons, nitrogen oxides, and various hydrocarbons.
Extinguishing Media
Carbon dioxide (CO2), water, water fog, dry chemical.
Fire Fighting Equipment/Instructions
Use NIOSH-approved self-contained breathing apparatus operating in the pressure demand mode and full fire fighting
protective clothing. Avoid inhalation of vapors.
Section 6 - Accidental Release Measures
Containment Procedures
MDI in contaminated areas can be neutralized with an ammonia/water solution (80% water, plus 20% non-ionic surfactant, or
90% water, 3-8% ammonia, plus 2% detergent. Use 10 parts neutralizer per one part isocyanate.) Allow containers of
neutralized solution to stand, uncovered, for 48 hours to allow carbon dioxide (CO2) to escape. Small spills should be allowed
to stand at least 15 minutes.
Clean-Up Procedures
Place in closable container for disposal.
Section 7 - Handling and Storage
Handling Procedures
Use protective equipment as described in Section 8 of this safety data sheet when handling uncontained material. Handle in
accordance with good industrial hygiene and safety practices.
Storage Procedures
Warehouse storage should be in accordance with package directions, if any. Product should be kept in a cool and dry area in
original packaging. Do not freeze.
Section 8 - Exposure Controls / Personal Protection
Exposure Guidelines
A: General Product Information
Protective equipment should be provided as necessary to prevent inhalation of vapors, prolonged skin contact, and to keep
exposure levels below the applicable exposure limits.
B: Component Exposure Limits

Personal Protective Equipment: Skin
Impervious gloves such as nitrile rubber should be used to help prevent excessive skin contact.
Personal Protective Equipment: Respiratory
A NIOSH approved respirator must be used if vapor concentrations exceed exposure limits.
Ventilation
Local exhaust or general dilution ventilation may be required to maintain exposures below the applicable exposure limits. The
need for ventilation systems should be evaluated by a professional industrial hygienist, while the design of specific ventilation
systems should be conducted by a professional engineer.
Personal Protective Equipment: General
Protective equipment should be provided as necessary to prevent irritation of the throat, eyes, and skin, and to keep
exposures below the applicable exposure limits identified in Section 8.

Section 11 - Toxicological Information
Acute Toxicity
A: General Product Information
MDI is an allergic sensitizing agent that may produce wheezing, coughing, shortness of breath, runny nose, sore throat,
coughing, and reduced lung function. Effects may be delayed. Eye contact may cause irritation with tearing (watery eyes),
reddening, and swelling. Ingestion may produce irritation, and corrosive effects on the digestive system.

Chronic Toxicity
If the material is heated isocyanates, mainly diisopropylphenyl isocyanate may be released. Repeated or prolonged exposure
to isocyanates in general may result in isocyanate sensitization (chemical asthma) in some individuals, causing them to react
to isocyanate exposure at concentrations below the established exposure limits. Symptoms include chest tightness, wheezing,
coughing, and shortness of breath. Effects can be delayed. Overexposure can cause lung damage, including decreased lung
function. Prolonged or repeated skin contact may cause irritation leading to dermatitis. Skin sensitization may also occur.
Teratogenicity
MDI: In laboratory animals, MDI/polymeric and MDI did not produce birth defects; other fetal effects occurred only at high
doses which were toxic to the mother.
