3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
PHYSICAL APPEARANCE: Brown liquid
IMMEDIATE CONCERNS: Irritating to eyes, respiratory system, and skin. Inhalation at
levels above the occupational exposure limit could cause risk of damage to respiratory
system. The onset of respiratory symptoms may be delayed for several hours after
exposure.
POTENTIAL HEALTH EFFECTS
EYES: Liquids and vapors are irritating to the eyes and can cause stinging, burning, or tearing.
SKIN: Moderate irritant. Repeated and/or prolonged contact may cause skin sensitization.
INGESTION: Ingestion may cause irritation of the gastrointestinal tract and gastrointestinal
discomfort with any of the following symptoms: nausea, vomiting, lethargy, or diarrhea.
INHALATION: Inhalation of vapors or mist at concentrations above the TLV can cause
respiratory tract irritation. (nose, throat, or lungs) Chronic inhalation can result in
sensitization.
MEDICAL CONDITIONS AGGRAVATED: Asthma, other respiratory disorders (bronchitis,
emphysema, bronchia hyperreactivity), skin allergies, eczema.
Klingstone Paths Page 2 of 7
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. For severe exposure, seek medical attention immediately. For
lesser exposure, seek medical attention if swelling or redness occurs, or if irritation persists
after being washed.
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. Seek immediate medical attention.
INHALATION: Remove individual from exposure, keep warm and at rest. If dizzy or shows signs
of respiratory distress, obtain immediate medical attention. Asthmatic-type symptoms may
develop and may be immediate or delayed up to several hours.
5. FIRE FIGHTING MEASURES
FLASHPOINT AND METHOD: > 200 oF (93.3oC) - Closed Cup
EXTINGUISHING MEDIA: Dry Chemical, Carbon Dioxide, Chemical Foam, Water Fog or
Spray.
HAZARDOUS COMBUSTION PRODUCTS: Carbon Monoxide, Carbon Dioxide, Nitrous
Oxide, and HCN.
COMMENT: Islolate fuel supple 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.
FIRE FIGHTING PROCEDURES: Isolate fuel supply from fire. Use water spray to cool fire-
exposed containers. Wear respiratory protection when extinguishing fire.
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. Treat with 10 parts
decontamination solution to 1 part isocyanate. Mix well. Allow to stand uncovered 48 hours
before disposal.
Klingstone Paths Page 3 of 7
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. Do not use
combustible material such as sawdust. Place in a chemical waste container. Move to outside
well-ventilated area. Treat with 10 parts decontamination solution to 1 part isocyanate. Mix
well. Allow to stand uncovered 48 hours before disposal. Clean spill area with decontamination
solution and allow to stand for 15 minutes before removal. Test atmosphere for MDI.
DECONTAMINATION SOLUTION: Decontamination solution: concentrated ammonia (5%),
detergent (2%), and water (93%)
RELEASE NOTES: Spills and releases may have to be reported to Federal and/or local
authorities. See Section 15 regarding reporting requirements.
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: Material is hygroscopic and reacts with water. It will form cured
particles or a film when exposed to atmospheric moisture. Blanket containers with nitrogen
before resealing.
