SDS

There is no effective therapy for sensitised workers.
[Ellenhorn and Barceloux; Medical Toxicology]
NOTE:
Isocyanates cause airway restriction in naive individuals with the degree of response dependant on the concentration and duration of exposure. They induce smooth muscle
contraction which leads to bronchoconstrictive episodes. Acute changes in lung function, such as decreased FEV1, may not represent sensitivity.
[Karol & Jin, Frontiers in Molecular Toxicology, pp 56-61, 1992]
Personnel who work with isocyanates, isocyanate prepolymers or polyisocyanates should have a pre-placement medical examination and periodic examinations thereafter, including a
pulmonary function test. Anyone with a medical history of chronic respiratory disease, asthmatic or bronchial attacks, indications of allergic responses, recurrent eczema or
sensitisation conditions of the skin should not handle or work with isocyanates. Anyone who develops chronic respiratory distress when working with isocyanates should be removed
from exposure and examined by a physician. Further exposure must be avoided if a sensitivity to isocyanates or polyisocyanates has developed.
SECTION 5 Fire-fighting measures
Extinguishing media
Small quantities of water in contact with hot liquid may react violently with generation of a large volume of rapidly expanding hot sticky semi-solid foam.
Presents additional hazard when fire fighting in a confined space.
Cooling with flooding quantities of water reduces this risk.
Foam.
Dry chemical powder.
BCF (where regulations permit).
Special hazards arising from the substrate or mixture
Fire Incompatibility
Avoid contamination with oxidising agents i.e. nitrates, oxidising acids, chlorine bleaches, pool chlorine etc. as ignition may result
Special protective equipment and precautions for fire-fighters
Fire Fighting
When silica dust is dispersed in air, firefighters should wear inhalation protection as hazardous substances from the fire may be adsorbed on
the silica particles.
When heated to extreme temperatures, (>1700 deg.C) amorphous silica can fuse.
Alert Fire Brigade and tell them location and nature of hazard.
Wear full body protective clothing with breathing apparatus.
Prevent, by any means available, spillage from entering drains or water course.
Fire/Explosion Hazard
Polyurethane polymer is a combustible material which may be ignited if exposed to an open flame. Decomposition from fire can produce
significant amounts of carbon monoxide and hydrogen cyanide, in addition to nitrogen oxides, isocyanates, and other toxic products. Because of
the flammability of the material, it may to be treated with flame retardants , almost all of which are considered harmful.
When silica dust is dispersed in air, firefighters should wear inhalation protection as hazardous substances from the fire may be adsorbed on
the silica particles.
When heated to extreme temperatures, (>1700 deg.C) amorphous silica can fuse.
-
Combustible.
-
Moderate fire hazard when exposed to heat or flame.
-
When heated to high temperatures decomposes rapidly generating vapour which pressures and may then rupture containers with release of
flammable and highly toxic isocyanate vapour.
Combustion products include:
carbon dioxide (CO2)
isocyanates
hydrogen cyanide
and minor amounts of
nitrogen oxides (NOx)
silicon dioxide (SiO2)
other pyrolysis products typical of burning organic material.
May emit corrosive fumes.
When heated at high temperatures many isocyanates decompose rapidly generating a vapour which pressurises containers, possibly to the point
of rupture. Release of toxic and/or flammable isocyanate vapours may then occur

Methods and material for containment and cleaning up
Minor Spills
Remove all ignition sources.
Clean up all spills immediately.
Avoid breathing vapours and contact with skin and eyes.
Personal Protective Equipment advice is contained in Section 8 of the SDS.
SECTION 7 Handling and storage
Precautions for safe handling
Safe handling
Avoid all personal contact, including inhalation.
Wear protective clothing when risk of exposure occurs.
Use in a well-ventilated area.
DO NOT
allow clothing wet with material to stay in contact with skin
