LEL: Unknown  UEL: Unknown

Extinguishing Media:
Water fog, foam, CO2, or dry chemical.

Fire Fighting Procedures:
Use water spray to cool adjacent surfaces and fire exposed containers. Protect against inhalation of combustion products.

Firefighters should wear full protective clothing including self-contained breathing apparatus to prevent inhalation of smoke and decomposition products. Toxic fumes and vapors may be involved.

Hazardous Decomposition Products:
No Decomposition if used according to specifications

Special Fire & Explosion Hazards:
Keep work areas free from open flames, sparks, hot metal surfaces and other sources of ignition. Ground objects prone to static electricity. Heat from fire can generate flammable vapors. Avoid contamination with moisture, alcohol, ammonia, amines, and alkalies that react with Isocyanates. Will react vigorously with water.

Product is not self-igniting.

SECTION 5 - HEALTH HAZARD DATA

Permissible Exposure Limit:
Not Established

Signs and Symptoms of Exposure:
Eye contact may result in conjunctival irritation and mild corneal opacity. Skin contact may result in irritative or allergic dermatitis. Inhalation of vapors may cause irritation of the mucous membrane of the nose, throat, or trachea, shortness of breath, chest discomfort, difficulty breathing and reduced pulmonary function. Exposure of fumes above the PEL may result in eye irritation, headache, chemical bronchitis, asthma-like symptoms or pulmonary edema. Isocyanates have also been reported to cause hypersensitivity pneumonitis, characterized by flu-like symptoms, the onset of which may be delayed. Neurologic effects after exposure to high levels of Diisocyanates can include euphoria, anxiety, personality changes, memory defictits, depression or paranoia. Aerosol MDI LC50: 490 mg/M³, rat: MDI LD50: > 10,000 mg/kg, rat.

Effects of Overexposure:
Medical Conditions Aggravated by Exposure:
May cause minor temporary eye or respiratory system irritation. May cause skin irritation when contact is made with skin area that is cut or scratched.

Acute:
None on ingestion.

Chemical Listed as a Carcinogen (or Potential Carcinogen):
Carbon black is an IARC class 2B Carcinogen and is possibly carcinogenic to humans: limited evidence in humans in the absence of sufficient evidence in experimental animals.

Chronic:
Acute or chronic overexposure to Isocyanates may cause sensitization resulting in allergic symptoms of the lower respiratory tract, including shortness of breath and difficulty in breathing. Asthma caused by Isocyanates including MDI, may persist after removal from exposure and may be irreversible. Long term exposure to Isocyanates has been reported to cause lung damage, including reduces lung function, which may be permanent.

Emergency & First Aid Procedures:
Eye Contact: 
Flush with gentle stream of water for a minimum of 15 minutes and contact a physician.
Skin Contact:
Clean with rubbing alcohol, followed by soap and water. When skin contact is made with a mixture of Parts A & B, the product must be removed immediately using Acetone.
Inhalation:
Remove to fresh air. Administer oxygen or artificial respiration, if necessary. Call physician.
Ingestion:
Consult a Physician. DO NOT INDUCE VOMITING. Inform the physician of the nature of the product.
Primary Route of Entry:
Inhalation.  

SECTION 6 - REACTIVITY DATA

Incompatibility:
Strong oxidizers, acids, bases, and moisture.

Hazardous Decomposition Products:
Toxic gases or vapors, such as oxides of carbon and nitrogen along with traces of butadiene may be released during a fire.

Hazardous Polymerization:
May occur.

Conditions to Avoid:
Strong oxidizers, moisture, acid and bases.  Contact with phosphorus may produce by-products.

SECTION 7 - SPILL OR LEAK PROCEDURES

Steps to be taken in case material is released or spilled:
Small spill:
Wear protective equipment including eye protection, rubber gloves, rubber boots, and self-contained breathing apparatus in the pressure mode, or an air supplied respirator. Absorb using inert material. Use non-sparking tools. Transfer into secure DOT approved waste containers for proper disposal. Use personal protective equipment as outlined below.

Large Spill:
Same as small spill.

Waste Disposal Method:
Dispose of according to local, state, and federal regulations.

SECTION 8 - SPECIAL PROTECTION

Respiratory Protection:
Use NIOSH-Certified respiratory protection for organic vapor if necessary.

Eye Protection:
Impervious safety glasses  are recommended.

Protective Gloves:
Impervious gloves are recommended to prevent skin contact.

Other Protective Equipment:
Under normal application conditions, protective glasses, gloves, and clothing are adequate.

Ventilation:
Provide adequate ventilation to maintain airborne concentrations below OSHA PELs.

SECTION 9 - SPECIAL PRECAUTIONS OR OTHER COMMENTS

Storage/Handling:
Store in cool, dry, well ventilated facility.  Store and use away from all sources of direct heat and ignition. Keep containers closed when not in use.

Other Precautions:
Provide adequate ventilation and avoid prolonged or repeated contact with the skin. Wash with soap and water immediately after contact.

Work/Hygienic Practices:
Maintain good personal hygiene practices. Wash contaminated clothing before reuse. Do not eat, drink, or smoke in work areas. Wash exposed skin before eating, drinking, smoking, or applying cosmetics
