First-aid measures

General advice: Take off all contaminated clothing immediately.
If inhaled: Take the person into the fresh air and keep him warm, let him rest; if there is difficulty
in breathing, medical advice is required.
In case of skin contact: In case of skin contact wash affected areas thoroughly with soap and
plenty of water. Consult a doctor in the event of a skin reaction.
In case of eye contact: Hold the eyes open and rinse with preferably lukewarm water for a
sufficiently long period of time (at least 10 minutes). Contact an ophthalmologist.
If swallowed: DO NOT induce the patient to vomit, medical advice is required.

Fire-fighting measures

Suitable extinguishing media: Carbon dioxide (CO2), Foam, extinguishing powder, in cases of
larger fires, water spray should be used.
Unsuitable extinguishing media: High volume water jet
Burning releases carbon monoxide, carbon dioxide, oxides of nitrogen, isocyanate vapors and
traces of hydrogen cyanide. In the event of fire and/or explosion do not breathe fumes.
During fire-fighting respirator with independent air-supply and airtight garment is required.
Do not allow contaminated extinguishing water to enter the soil, ground-water or surface waters.

Accidental release measures

Personal precautions: Put on protective equipment (see chapter 8). Ensure adequate
ventilation/exhaust ventilation. Keep unauthorized persons away.
Environmental precautions: Do not allow to escape into waterways, wastewater or soil.
Methods for cleaning up: Remove mechanically; cover the remainder with wet, absorbent
material (e.g. sawdust, chemical binder based on calcium silicate hydrate, sand). Remove
mechanically; cover remainder with wet, absorbent material (e.g. sawdust, chemical binder
based on calcium silicate hydrate, sand). After approx. one hour transfer to waste container and
do not seal (evolution of CO2!). Keep damp in a safe ventilated area for several days.

Handling and storage

Provide sufficient air exchange and/or exhaust in work rooms. Exhaust ventilation necessary if
product is sprayed.
The threshold limit values noted in the SDS must be monitored. In all areas where isocyanate
aerosols and/or vapour concentrations are produced in elevated concentrations, exhaust
ventilation must be provided in such a way that the workplace exposure limits (WEL) is not
exceeded. The air should be drawn away from the personnel handling the product
The personal protective measures described in the SDS must be observed. The precautions
required in the handling of isocyanates must be taken. Avoid contact with skin and eyes and the
inhalation of vapour.
Keep container dry and tightly closed in a cool and well ventilated place.

Exposure controls / personal protection

Respiratory protection:
Respiratory protection in case of vapour/aerosol release. Combination filter for gases/vapours of
organic compounds and solid and liquid particles (f.e. EN 14387 Type A-P2)

Hand protection:
Chemical resistant protective gloves (EN 374)
Suitable materials short-term contact and/or splashes (recommended: At least protective index 2,
corresponding > 30 minutes of permeation time according to EN 374)
butyl rubber (butyl) - 0.7 mm coating thickness
Manufacturer's directions for use should be observed because of great diversity of types.

Eye protection:
Safety glasses with side-shields (frame goggles) (e.g. EN 166)

Body protection:
Body protection must be chosen depending on activity and possible exposure, e.g. apron, protecti
boots, chemical-protection suit (according to EN 14605 in case of splashes or EN ISO 13982 in ca of

General safety and hygiene measures
Handle in accordance with good industrial hygiene and safety practice. Wearing of closed work
clothing is required additionally to the stated personal protection equipment. Avoid inhalation of
mists. Contact with eyes and skin must be avoided.

Stability and reactivity

No hazardous reactions if stored and handled as prescribed/indicated.
Corrosion to metals: Corrosive effects to metal are not anticipated.
Formation of flammable gases: Remarks: Forms no flammable gases in the presence of water.
Chemical stability
The product is stable if stored and handled as prescribed/indicated.
Possibility of hazardous reactions
Reacts with alcohols. Reacts with amines. Reacts with substances which contain active hydrogen.
Reacts with water, with formation of carbon dioxide. The formation of gaseous decomposition products builds up pressure in tightly closed

Disposal considerations

Waste treatment methods:
Incinerate in suitable incineration plant, observing local authority regulations.
Contaminated packaging:
Uncontaminated packaging can be re-used.
