### 4. FIRST AID MEASURE S

Inhalation: Move to fresh air. If breathing is irregular or stopped, administer artificial respiration. Call

a physician immediately.

Skin contact: Take off all contaminated clothing immediately. Wash off immediately with soap and

plenty of water. If skin irritation persists, call a physician. Wash contaminated clothing before re

- use.

Eye contact: Flush eyes with water as a precaution. If eye irr itation persists, consult a specialist.

Ingestion: Never give anything by mouth to an unconscious person. If a person vomits when lying on

his back, place him in the recovery position. Do not induce vomiting. Rinse mouth. Immediately give

large quantities of water to drink. Call a physician immediately.

Notes to physician

Bronchial constriction may develop after extensive exposure to isocyanates, even in individuals who

have not been shown tobe previously sensitized.



### 5. F IRE

- FIGHTING MEASURES

Flash point 5 °C ( 41 °F )

Lower explosion limit No data available

Upper explosion limit No data available

Thermal decomposition Heating or fire conditions liberates toxic gas.

Combustion Products: Hydrogen Cyanide

Carbon monoxide

Carbon dioxide

Nitrogen oxide (NO2)

Suitable extinguishing

media: foam

carbon dioxide (CO2)

dry powder

Specific hazards during fire fighting: Vapors can travel to a source of ignition and flash back.

Heated material can form flammable or explosive vapors with air. Closed containers may rupture via

pressure build

- up when exposed to fire or extreme heat.

Special protective equipment for fire

- fighters: Wear self

- contained breathing apparatus and

protect ive suit.

Further information: For safety reasons in case of fire, containers should be stored separately in

closed containments.

Cool closed containers exposed to fire with water spray.

EXPLOSION HAZARD. Fight advanced fires from a protected location.

C ollect contaminated fire extinguishing water separately. This must not be discharged into drains.

Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local

regulations.



### 6. ACCIDENTAL RELEAS E MEASURES

Personal precautionsCR 842B

Page 4 of 8 Revision date 04/19/2006 Use personal protective equipment.

Refer to protective measures listed in sections 7 and 8.

MATERIAL IS A POTENTIAL SENSITIZER.

If exposed to material during clean

- up operations, IMMEDIATELY remove all contaminated clothing

and wash ex posed skin areas with soap and water. See SECTION 4, First Aid Measures, for further

information.



### Environmental precautions

Do not flush into surface water or sanitary sewer system.



### Methods for cleaning up

Evacuate personnel to safe areas.

Remove all sources of ignition.

Ensure adequate ventilation.

Contain and collect spillage with non

- combustible absorbent material, (e.g. sand, earth, diatomaceous

earth, vermiculite) and place in container for disposal according to local / national regulat ions (see

section 13).



### 7. HANDLING AND STOR AGE

Handling

Provide sufficient air exchange and/or exhaust in work rooms. Avoid exceeding of the given

occupational exposure limits (see section 8). In case of insufficient ventilation, wear suitable

respirato ry equipment. Do not breathe vapours or spray mist. Wear personal protective equipment.

For personal protection see section 8. Keep away from heat and sources of ignition. Take necessary

action to avoid static electricity discharge (which might cause ignition of organic vapours). Ensure all

equipment is electrically grounded before beginning transfer operations. May cause sensitization of

susceptible persons by skin contact. CONTAINERS MAY BE HAZARDOUS WHEN EMPTY. Since

emptied containers retain product residue follow all MSDS and label warnings even after container is

emptied.



### Storage

Storage conditions: Material can burn; limit indoor storage to approved areas equipped wit h

automatic sprinklers. Keep container tightly closed in a dry and well

- ventilated place. Keep away from

heat and sources of ignition. Electrical installations / working materials must comply with the

technological safety standards.

degradation or chemical breakthrou gh. Before removing gloves clean them with soap and water.

NOTE: Material is a possible skin sensitizer.

Skin and body protection: complete suit protecting against chemicals safety shoes

Respiratory protection: A respiratory protection program meeting OSHA 1910.134 and ANSI Z88.2

requirements or equivalent 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. Abo ve the exposure limit: Wear a properly fitted NIOSH approved (or

equivalent) self

- contained breathing apparatus in the pressure demand mode, OR full

- facepiece,

airline respirator in the pressure demand mode with emergency escape provision.

Hygiene measures: Wash hands before breaks and immediately after handling the product.

Protective measures: Facilities storing or utilizing this material should be equipped with an eyewash

facility and a safety shower.
