attention. In case of shortness of breath, give oxygen.

Skin contact: Remove contaminated clothing. Wash off with soap and plenty of water. Wash 

contaminated clothing before re-use. Do not take clothing home to be laundered. Consult a 

physician.

Eye contact: Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.

Ingestion: Drink 1 or 2 glasses of water. Consult a physician. If vomiting occurs spontaneously, keep 

airway clear. Never give anything by mouth to an unconscious person.

Notes to physician

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

have not been shown tobe previously sensitized. MATERIAL IS SEVERELY IRRITATING. It may not 

be advisable to induce vomiting. Possible mucosal damage may contraindicate the use of gastric 

lavage.

5. FIRE-FIGHTING MEASURES

Flash point -1 °C ( 30.20 °F ) Abel Closed Cup

Lower explosion limit 2.10 %(V)Ethyl acetate

Upper explosion limit 11.50 %(V)Ethyl acetate

Suitable extinguishing 

media:

Use the following extinguishing media when fighting fires involving this 

material:

carbon dioxide (CO2)

dry powder

foam

Water in very large quantities.

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. During a fire, irritating and highly toxic gases 

and/or fumes may be generated during combustion or decomposition. DO NOT permit water to enter 

containers. Closed containers may explode when heated or contents contaminated with water.

Special protective equipment for fire-fighters: In the event of fire, wear self-contained breathing 

apparatus.

Further information: EXPLOSION HAZARD. Fight advanced fires from a protected location.

Cool closed containers exposed to fire with water spray.

DO NOT permit water to enter containers.

Remain upwind.

Avoid breathing smoke.

Contain run-off.

6. ACCIDENTAL RELEASE MEASURES

Personal precautions
COREACTANT 9H1H

Page 4 of 8 Revision date 05/16/2006

Appropriate protective equipment must be worn when handling a spill of this material. See SECTION 

8, Exposure Controls/Personal Protection, for recommendations.

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.

Wash contaminated clothing before re-use.

Do not take clothing home to be laundered.

Environmental precautions

WARNING: KEEP SPILLS AND CLEANING RUNOFFS OUT OF MUNICIPAL SEWERS AND OPEN 

BODIES OF WATER.

Methods for cleaning up

Eliminate all ignition sources.

Evacuate personnel to safe areas.

Ventilate the area.

Floor may be slippery; use care to avoid falling.

Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal binder, sawdust).

Sweep up or vacuum up spillage and collect in suitable container for disposal.

No sparking tools should be used.

Avoid all contact.

Avoid breathing vapor.

NOTE: Spills on porous surfaces can contaminate groundwater.

7. HANDLING AND STORAGE

Handling

Vapors can be evolved when material is heated during processing operations. See SECTION 8, 

Exposure Controls/Personal Protection, for types of ventilation required. Use non-sparking tools and 

grounding cables when transferring. This material is a potential skin sensitizer. See SECTION 8, 

Exposure Controls/Personal Protection, prior to handling. Wash after handling and shower at end of 

work period.

Further information on storage conditions: Residual vapors in empty containers may explode on 

ignition. DO NOT cut, drill, grind or weld on or near container.

Storage

Storage conditions: Avoid temperature extremes during storage; ambient temperature preferred. 

Store away from excessive heat (e.g. steampipes, radiators), from sources of ignition and from 

reactive materials. Material can burn; limit indoor storage to approved areas equipped with automatic 

sprinklers. Store out of direct sunlight in a cool place. Keep containers tightly closed in a cool, wellventilated place. Avoid all ignition sources. Ground all metal containers during storage and handling. 

Keep material dry. Moisture may affect product quality.

Further information:

CONTAINERS MAY BE HAZARDOUS WHEN EMPTY. Since emptied containers retain product 

residue follow all MSDS and label warnings even after container is emptied.

Improper disposal or re-use of this container may be dangerous and illegal. Refer to applicable local, 

state and federal regulations.

Eye protection: Use chemical splash goggles (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): VITON Synthetic Rubber (registered Trademark of 

Dupont Dow Elastomers) Polyvinyl alcohol 4H Glove (Trademark of Safety 4 A/S of Denmark) 

Gloves should be removed and replaced immediately if there is any indication of degradation or 

chemical breakthrough. Rinse and remove gloves immediately after use. Wash hands with soap and 

water.

Skin and body protection: Use chemically resistant apron or other impervious clothing to avoid 

prolonged or repeated skin contact. Where splashing is possible, full chemically resistant protective 

clothing (e.g. acid suit) and boots are required.

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.

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 

exhaust systems.
