4. FIRST AID MEASURES

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 irritation 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. FIRE-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 

protective 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.

Collect 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 RELEASE MEASURES

Personal precautions
CR 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 exposed 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 regulations (see 

section 13).

7. HANDLING AND STORAGE

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 

respiratory 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 with 

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.

Eye protection: Use chemical splash goggles and face shield (ANSI Z87.1 or approved equivalent). 

Eye protection worn must be compatible with respiratory protection system employed.

Hand protection: Chemical-resistant gloves should be worn whenever this material is handled. The 

glove(s) listed below may provide protection against permeation. (Gloves of other chemically resistant 

materials may not provide adequate protection): 4H Glove (Trademark of Safety 4 A/S of Denmark) 

Butyl rubber Gloves should be removed and replaced immediately if there is any indication of 

degradation or chemical breakthrough. 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. Above 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.

Engineering measures: Use explosion-proof local exhaust ventilation with a minimum capture 

velocity of 100 ft/min (0.5 m/sec) at the point of vapor evolution. Refer to the current edition of 

Industrial Ventilation: A Manual of Recommended Practice published by the American Conference of 

Governmental Industrial Hygienists for information on the design, installation, use, and maintenance of
