3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
PHYSICAL APPEARANCE: Clear to yellow liquid.
IMMEDIATE CONCERNS: Irritating to eyes, respiratory system, and skin. Can irritate and burn
the eyes, causing potential permanent damage. Harmful if vapors and mists are inhaled.
POTENTIAL HEALTH EFFECTS
EYES: Severe eye irritant. Can cause permanent damage.
SKIN: Prolonged contact can cause reddening, swelling, rash or blistering.
INGESTION: Ingestion could result in irritation and corrosive action in the mouth, stomach tissue
and digestive tract. These irritations would likely be followed by vomiting and cramps.
INHALATION: Inhalation of vapors or mist at concentrations above the TLV can cause
respiratory tract irritation. (nose, throat, lungs) Chronic inhalation can result in sensitization.
MEDICAL CONDITIONS AGGRAVATED: Asthma, other respiratory disorders (bronchitis,
emphysema, bronchia hyperreactivity), skin allergies, eczema.
ROUTES OF ENTRY: Inhalation, skin contact, eye contact, ingestion.

SENSITIZATION: Any individual with isocyanate sensitization should not be exposed to this
product. These individuals can react to exposure well below the TLV. Symptoms can occur
immediately or several hours after exposure.
4. FIRST AID MEASURES
EYES: Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower
eyelids occasionally. Get immediate medical attention.
SKIN: Remove contaminated clothing. Wash affected areas thoroughly with soap and water. Wash
clothing thoroughly before reuse. Get immediate medical attention.
INGESTION: Do not induce vomiting. Never give anything by mouth to a drowsy or unconscious
person. If the individual is conscious, rinse mouth with water. Give 1 to 2 cups of water to drink.
Get immediate medical attention.
INHALATION: Remove individual from exposure, keep warm and at rest. If respiratory irritation or
other symptoms develop, get medical attention.
5. FIRE FIGHTING MEASURES
FLASHPOINT AND METHOD: > 200 oF (93.3 oC) - Closed Cup
EXTINGUISHING MEDIA: Alcohol foam, Dry Chemical, Carbon Dioxide, Water Fog or Spray.
HAZARDOUS COMBUSTION PRODUCTS: During a fire, irritating and highly toxic gases may be
generated by thermal decomposition or combustion.
FIRE FIGHTING PROCEDURES: Isolate fuel supply from fire. Use water spray to cool fire-
exposed surfaces and containers. Fire fighters should wear self-contained breathing apparatus in
addition to emergency fire fighting protective clothing.
6. ACCIDENTAL RELEASE MEASURES
SMALL SPILL: Clean up spills wearing proper personal protective equipment. (See section 8)
Absorb with dry chemical absorbent, earth, sand, or any other inert material. Place in a chemical
waste container. Move to outside well-ventilated area.
LARGE SPILL: Eliminate all ignition sources. Evacuate and ventilate the area. Create a dike or
trench to contain materials. Prevent entry into waterways, sewers, basements or confined areas.
Clean-up personnel should wear appropriate personal protection equipment. (see section 8) Absorb
with dry chemical absorbent, earth, sand, or any other inert material. Place in a chemical waste
container and cover loosely. Move to outside well-ventilated area. Allow to stand uncovered 48
hours before closing container.

COMMENT: Dispose of by any standard method of disposal in accordance with good industrial
practice and in compliance with federal, state, and local environmental protection regulations.
7. HANDLING AND STORAGE
HANDLING: Wear proper personal protective equipment. Use in a well ventilated area. Avoid
smoking, bare lights, or ignition sources. Avoid physical damage to containers.
STORAGE: Protect from atmospheric moisture. Keep containers sealed in order to avoid
contamination. Do not reseal if contaminated. After container has been opened, blanket with
nitrogen before resealing. Store indoors in a cool, well-ventilated area.
STORAGE TEMPERATURE: 55 oF ?120 oF (12.8 oC ?48.9 oC)
SHELF LIFE: 1 Year
SPECIAL SENSITIVITY: IDPI reacts with water to form toxic and corrosive substances.
