Special fire fighting procedures: Exposure to heated or burning product can be particularly dangerous.
Firefighters should wear self-contained breathing apparatus and NFPA-compliant helmet, hood,
boots, and gloves. Avoid contact with product. Decontaminate equipment and clothing prior to
reuse. Use cold-water spray to cool fire-exposed containers to minimize the risk of rupture.
Unusual Fire and Explosion Hazards: Material reacts with water. For large fires, use a large volume of
water applied from a safe distance, as reaction with water can be vigorous.
Reactivity Data
Stability Stable under normal storage and use Conditions to avoid: Moisture,
conditions temperatures above 350掳F
Incompatibility (Materials to Avoid): Water, amines, strong bases, alcohols, copper alloys
Hazardous Decomposition or Byproducts: Oxides of nitrogen, carbon monoxide, carbon dioxide,
hydrogen cyanide, isocyanates, isocyanic acid, amines and other undetermined compounds will

Health Hazard Data
Carcinogenicity: Not regulated as a carcinogen by OSHA, IARC, or NTP.
Effects, Signs, and Symptoms of Overexposure:
Primary route of exposure: Skin or eye contact. Skin contact or inhalation (repeated or a single
large dose) may result in sensitization to diisocyanates. Once sensitized, later exposure to very
small amounts can cause an asthma-like reaction that can be extremely severe.
Skin contact: Skin irritant. May cause an allergic skin reaction, with burning, redness, itching, and
swelling. Once someone has become sensitized, even slight contact can cause the
skin reaction. Animal tests indicate that skin contact can lead to an allergic
respiratory reaction.
Eye contact: Irritation. Can cause reddening, tearing, stinging, swelling. May cause temporary
corneal injury.
Inhalation: Low vapor pressure; primary inhalation risk is if sprayed or heated. Can cause
respiratory tract irritation, with symptoms of runny nose, sore throat, coughing, chest
discomfort, and shortness of breath. People with preexisting nonspecific bronchial
hyperreactivity can develop symptoms of chest discomfort, shortness of breath, or
asthma-like symptoms at concentrations below the legal or recommended exposure
limits. Can cause immediate or delayed hypersensitivity reactions. Repeated
overexposure may cause lung damage, including a permanent decrease in lung
function.
Not likely to occur. May cause irritation, abdominal pain, nausea, vomiting, and
Ingestion:
diarrhea.
Medical Conditions Generally Aggravated by Exposure:
Pre-existing asthma, respiratory disorders, skin allergies, and eczema may be aggravated by
exposure to this product.
Emergency and First Aid Procedures:
Eyes: Immediately flush eyes with plenty of water for at least 15 minutes while holding eyelids
open. Get medical attention if eyes are burning, tearing, red, or otherwise irritated after flushing.
Skin: Immediately remove contaminated clothing or shoes. Wash off with soap and water
(lukewarm water if possible). Polyglycol-based cleaners or corn oil may be more effective than
soap and water. Do not reuse clothing until thoroughly decontaminated by soaking for an hour
in an 8% ammonia solution prior to laundering. Get medical attention if irritation develops.
Inhalation: Move victim to fresh air and provide oxygen if breathing is difficult. Give artificial
respiration or oxygen if breathing problems develop. Get medical attention as needed;
immediately if asthmatic symptoms develop. Asthmatic symptoms may not develop until
several hours after exposure. Extreme asthmatic reactions can be life-threatening.
Ingestion: Do NOT induce vomiting. Rinse mouth out thoroughly. Seek medical attention
immediately.

Notes to Physician:
Eye: Stain for evidence of corneal injury. If cornea is burned, instill antibiotic/steroid
preparation as needed.
Skin: This is a skin sensitizer. Treat symptomatically as for contact dermatitis or thermal burn.
Inhalation: Treatment is essentially symptomatic. A person with a dermal or pulmonary
sensitization reaction to this material should be removed from further exposure to any
diisocyanate.
Ingestion: Treat symptomatically. There is no specific antidote. Inducing vomiting is
contraindicated because of the material is an irritant.
Precautions for Safe Handling and Use
Steps to Be Taken in Case Material is Released or Spilled
Isolate the area. Remove ignition sources. Use appropriate protective equipment.
Small spills:
Stop the leak. Cover the spilled material with suitable absorbent material (cat litter,
Oil-Dri, etc.) Saturate absorbent material with neutralization solution and mix. Wait
15 minutes. Collect material in open-head metal containers. Repeat applications of
decontamination solution, with scrubbing, until the surface is decontaminated. Put
lid loosely on container holding the spilled material, so container can vent for 72
hours to let carbon dioxide escape.
Large spills: Evacuate non-emergency personnel. Isolate the area; prevent access. Remove
ignition sources. Notify management. Put on protective equipment. Stop leak only
if safe to do so. Ventilate. Contain the spill so it will not spread into drains, sewers,
water supplies, or soil. Standing liquid can be pumped into closed but not sealed
metal containers for disposal. Process can generate heat and carbon dioxide. Cover
spill area with suitable sorbent, then use solution below to neutralize. Notify
CHEMTREC (1-800-424-9300) of any spill occurring during distribution.
Neutralization solutions:
a) Colorimetric Laboratories (CLI) decontamination solution
b) 75% water: 20% nonionic surfactant (e.g., Poly-Tergent SL-62, Tergitol TMN-10):5% n-
propanol
c) 80% water: 20% nonionic surfactant (e.g., Poly-Tergent SL-62, Tergitol TMN-10)
d) 90% water: 3-8% ammonium hydroxide or concentrated ammonia: 2% liquid detergent
Waste Disposal Method:
Follow federal, state, and local regulations. The material can be reacted with Part A to form an
inert material. Incineration is the recommended method of disposal. The material is not a
listed or characteristic hazardous waste under the Resource Conservation and Recovery Act, but
state laws may vary. The end use is responsible for determining whether a material containing
or derived from this should be classified as a hazardous waste.

Precautions to be Taken in Handling and Storing
Store in cool, dry, well-ventilated location. Keep containers tightly closed to prevent moisture
contamination. Do not reseal if contamination is suspected. Product can react with water to
produce carbon dioxide; that can cause a hazardous pressure buildup if container is tightly
closed.
Wash thoroughly after handling. Do not smoke or use tobacco products during handling or use.
Material鈥檚 odor threshold is significantly higher than its exposure limits. Do not rely on odor as
an indicator of exposure.
Other Precautions:
Avoid breathing aerosols and mists that may be formed by spray applications.
Empty containers hold product residue. Do not heat or cut empty containers, as highly toxic
vapors and gases may be formed. Do not reuse without thorough commercial cleaning and
reconditioning. Thoroughly drain container before disposal.
Control Measures
Respiratory Protection:
Under normal use conditions, with general good ventilation and if material is not heated or
sprayed, no respirator is required. In inadequately ventilated areas or where the material is
sprayed, aerosolized, or heated and exposures may exceed occupational exposure limits, use a
NIOSH-approved respirator in accord with 29CFR1910.134.
At concentrations up to ten times the TLV or PEL, an air-purifying respirator with organic
vapor cartridges and P/100 particulate filters can be used, if the cartridge has an end-of-service-
life indicator certified by NIOSH or if a change-out schedule, reflecting conditions of use, has
been developed.
Ventilation:
Provide adequate general (dilution) ventilation to maintain worker exposure below exposure
limits.
Protective Clothing:
Wear chemical resistant gloves to prevent all skin contact. Nitrile gloves are effective; butyl
rubber, neoprene and PVC are also suitable. Do not use latex surgical gloves. Wear other
protective clothing (boots, coveralls) as needed to prevent any skin contact.
Eye Protection:
Wear chemical safety goggles and a face shield if there is any possibility of splashing or
spraying. Wear appropriate eye protection whenever handling the product.
Work/Hygienic Practices:
Eyewashes and safety showers should be available for emergency use.
