5. FIRE-FIGHTING MEASURES

Fire/Explosion Hazard
If safe to do so, move undamaged containers from fire area.

HAZARDOUS DECOMPOSITION PRODUCTS: Decomposes on heating emitting toxic fumes
including oxides of carbon and nitrogen, hydrogen cyanide and isocyanate vapours.

FIRE FIGHTING PROCEDURES: All non-essential members of the workforce should be moved
upwind of the fire and only trained and well-equipped personnel allowed near to the fire until the fire
service takes control of the situation. Fire fighters should wear Self-contained breathing apparatus
(SCBA) in confined spaces, in oxygen deficient atmospheres or if exposed to products of
decomposition. Full protective clothing is also recommended.

EXTINGUISHING MEDIA (SMALL FIRES): Use dry chemical or carbon dioxide. Water should not
be applied unless from a safe distance (e.g. by hoses) and in large quantities.

EXTINGUISHING MEDIA (LARGE FIRES): Can use large volumes of water, as normally applied
from a distance by hoses. Water-based protein or other fire fighting foams can be effective in
extinguishing such fires, as well as suppressing the release of diisocyanate vapours.

HAZCHEM CODE: None allocated [Aust]

FLAMMABILITY
This material is not flammable.

=======================================================================================

6. ACCIDENTAL RELEASE MEASURES

All spills should be attended to immediately. Evacuate from the immediate area everyone not essential
to dealing with the spill, and keep them upwind to avoid breathing vapour. Isolate the area and prevent
access. Wear protective equipment to prevent skin and eye contact, as outlined under personal
protection in this MSDS. Control the source of the leak, where possible. Ventilate area. Contain the
spill to prevent further spread of material and prevent run off into drains and waterways. Use absorbent
material such as wet sand, wet earth, wet sawdust or absorbent clays. These materials will not only
contain the spill, but also absorb and partially neutralise the diisocyanate content of the material.
Neutralise used absorbent materials and any remaining product with neutraliser (see below) and
decontaminate all surfaces and equipment that have been in contact. Dispose of all clean-up materials
in accordance with government regulations.

Neutraliser formulations include:
(a) surfactant 1 - 20% and water to make up to 100%;
(b) liquid surfactant 0.2 - 2%, sodium carbonate 5 - 10%, and water to make up to 100%;
(c) liquid surfactant 0.2 - 2%, concentrated ammonia 3 - 8% and water to make up to 100%.

=======================================================================================

7. HANDLING AND STORAGE

Water, either as liquid or as vapour, must be rigorously excluded from the material during both
handling and storage, as the product will react with water giving insoluble polyurea and liberating
carbon dioxide gas. In a closed container, this could cause the container to rupture.

Store in a cool place and out of direct sunlight. Store away from sources of heat or ignition. Store
away from strong oxidizing agents. Keep containers tightly closed, when not using the product. Store
in original packages as approved by manufacturer. Purge with nitrogen and close container when not
in use. Do not eat, drink or smoke in the workplace.

Refer to manufacturer for correct usage instructions for this product. This product should only be used
as intended by the manufacturer.

13. DISPOSAL CONSIDERATIONS

Do not allow into any sewers, drains, on the ground or into any body of water. Any disposal must be in
accordance with applicable State, Territory and/or Local government regulations.

Product Waste: The disposal of large quantities of product should normally be undertaken only by a
specialist contractor. The product may be incinerated in a suitable facility, however consult with local
authorities before doing so to ensure that all local regulations are observed.

In the case of only a small quantity of product waste, the following method may be applied, with
caution, by a technically competent person: The waste product is reacted with an excess of Polyol to
form a foam or solid polyurethane. The product of the reaction can then be incinerated or disposed of
in landfill. This process should be carried out slowly in an open drum to avoid rapid heat generation
and release of gases.

Container Disposal: Any disposal of contaminated packaging and washings must be in accordance with
State, Territory and/or Local government regulations. When containers/drums have been drained to
leave as little residue as possible, either seal the drum and send it to a drum-handling specialist, or
decontaminate the drum using a slow reacting water-based neutraliser (see below). Add (several
centimetres of) neutraliser to the drum, slowly shake and roll to allow contact. Leave open until all
reaction is completed, then dispose of drum and washings in approved manner. If the container is to be
reconditioned, the reconditioning company should be made aware of the nature of the original contents.

Neutraliser formulations:
(a) surfactant 1-20% and water to make up to 100%;
(b) liquid detergent 2%, PEG400 35% and water to make up to 100%.
