4. FIRST AID MEASURES
Eyes:
Immediately flush with water for 15 minutes. Get medical advice if irritation develops or
persists.
Skin:
Take of all contaminated clothing.
Wash contaminated area with soapy warm water. Get
medical advice if irritation develops or persists.
Wash contaminated clothing and clean
shoes before reuse.
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration, preferable mouth to mouth. If
breathing is laboured, give oxygen and consult a physician immediately. Never give
anything by mouth to an unconscious person.
Ingestion:
Consult a physician immediately. Give one or two glasses of water to drink. If vomiting
occurs, aspiration into the lungs may cause lung damage. Never give anything by mouth to
an unconscious person.
5. FIRE FIGHTING MEASURES
Flash Point ................................................................ 48.8 oC COC
Auto-ignition Temperature ..........................................No data available
Lower Explosive Limit .................................................0.7% (based on petroleum naphtha solvent)
Upper Explosive Limit .................................................6.0% (based on petroleum naphtha solvent)
Suitable Extinguishing Media:
Dry chemical, foam, carbon dioxide, halogenated agents. If water is used, use very large quantities. The
reaction between water and hot isocyanate may be vigorous.
Protective Equipment for Fire Fighting:
Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.
Unusual Fire and Explosion Hazards:
Water contamination will produce carbon dioxide. Do not reseal contaminated container as pressure
build-up may rupture them.
Thermal decomposition of this product may produce toxic fumes.
6. ACCIDENTAL RELEASE MEASURES
Eliminate all sources of ignition. Provide sufficient ventilation. Wear appropriate personal protective
equipment including gloves and safety glasses. Do not breathe vapour. Contain spill. Do not allow into
drains or waterways. Take up with absorbent material (e.g. sand, vermiculite, or commercially available
inorganic absorbent). Use non-sparking tools and equipment. Fill into suitable containers for disposal.
Water contamination will produce carbon dioxide. Do not reseal contaminated container as pressure
build-up may rupture them.
Get prepared before using this material with a decontamination solution of 0.2-0.5% liquid detergent and
3-8% ammonium hydroxide in water. Neutralise residue with decontamination solution and let it stand for
48 hours allowing carbon dioxide to vent away. Dispose of empty containers in accordance with federal,
state and local laws.
7. HANDLING AND STORAGE
CLASS 3 Flammable Liquid - Transport and store in accordance with Dangerous Goods
requirements.
Handling:
Observe normal standards of industrial hygiene for handling chemicals. Eliminate all sources
of ignition. Use in a well-ventilated area. Avoid breathing vapour and contact with skin and eyes. Wear
gloves, long sleeved shirt, and eye protection. A sensitised person should not be exposed to the product.
Storage:
Store in tightly sealed containers to protect from atmospheric moisture. Store in a cool, dry
area. Keep away from ignition sources such as fire, flame and sparks.
Empty container warning:
Do not reuse empty drums or containers unless professionally cleaned.
Empty containers may contain flammable vapours. Do not cut, drill, grind or weld on or near empty
containers.
Other Precautions:
Individuals with existing respiratory disease such as chronic bronchitis, emphysema
or asthma should not be exposed to isocyanates. Do not eat, drink or smoke when using the product.

Respiratory Protection
If vapours and mists occur, a respiratory protection program meeting Australian Standards AS-
1716 and AS-1715 requirements must be followed whenever workplace conditions warrant a
respirator’s use. None required if airborne concentrations are maintained below the exposure
limit listed in “Exposure Limit Information”
Eye Protection
Use chemical splash goggles (Australian Standard AS-1337) or approved equivalent. Eye
protection worn must be compatible with respiratory protection system employed. An eye wash
station and safety shower should be available in the work area.
Hand Protection
Impermeable gloves as necessary to prevent skin contact. E.g. nitrile or neoprene gloves.
Protective Clothing
Clothing made of the following material has excellent resistance to MDI: Tyvec, butyl nitrile
rubber or neoprene.
Engineering Controls (Ventilation)
Use local exhaust ventilation sufficient to maintain exposure levels below exposure limit
concentrations. Refer to Australian Standard AS-1668.

10. STABILITY AND REACTIVITY
Considered stable under normal conditions of use and handling.
Hazardous decomposition products
Combustion products: oxides of carbon, oxides of nitrogen and ammonia. Trace amounts of
hydrogen cyanide.
Hazardous polymerisation
May occur.
Materials to avoid
This material will react with any materials containing active hydrogen. Avoid water contact,
alcohols, amines, alkalis and acids.
Conditions to avoid
High temperatures in the presence of alkalis, tertiary amines, and metal compounds will
accelerate polymerisation. Possible evolution of carbon dioxide may rupture containers if
contaminated.
11. TOXICOLOGICAL INFORMATION
Acute Data
Inhalation:
May cause coughing, nausea, tightness of the chest with difficulty breathing. May
cause irritation of the nose, throat and respiratory tract.
Ingestion:
May cause irritation of the mouth, pharynx, oesophagus and stomach.
Skin irritation:
May cause irritation resulting in redness, rash and itching.
Eyes irritation:
May cause irritation if not washed out immediately.
Chronic effects:
Prolonged and repeated contact can result in skin sensitivity and allergic skin reactions
(rashes, hive-like swelling, blisters) resulting in dermatitis. Inhalation may cause
central nervous depression and asthma-like conditions upon prolonged inhalation.
Respiratory sensitisation may also result from prolonged and repeated exposure.
Carcinogenicity:
Toluene diisocyanate is a material that may reasonably be anticipated to be a
carcinogen, based on a NTP technical report. In the cited study, laboratory animals
gavaged TDI in corn oil developed cancer.
Signs and Symptoms of Exposure:
Chronic cough, tightness in the chest and difficulty breathing.
Redness of eyes, irritation of skin causing redness, itching, irritation of the mouth, pharynx, oesophagus
and stomach through ingestion.
Medical Conditions generally Aggravated by Exposure:
Prolonged and repeated exposure may result
in respiratory problems such as coughing, tightness of chest, dermatitis such as acne, hives and itching.
12. ECOLOGICAL INFORMATION
No available data.
13. DISPOSAL CONSIDERATIONS
Containers hazardous when empty. Do not reuse empty drums or containers unless professionally
cleaned. Empty containers may contain flammable vapours. Do not cut, drill, grind or weld on or near
empty containers. Dispose of waste and empty containers in accordance with federal, state and local
laws.
