Inhalation: Move to fresh air. Give artificial respiration if breathing has stopped. Get prompt medical 

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 to be 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 ( 33.8 °F ) DIN 53213

Ignition temperature 485.0 °C ( 905 °F) Ethyl acetate

Lower explosion limit 2.2 %(V)Ethyl acetate

Upper explosion limit 11.5 %(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.

Avoid breathing smoke.

Contain run-off.

6. ACCIDENTAL RELEASE MEASURES

Personal precautions

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.

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.

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 sensitizer. See SECTION 8, Exposure 

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

Persons susceptible to skin sensitisation problems or asthma, allergies, chronic or recurrent respiratory 

disease should not be employed in any process in which this mixture is being used.

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. Avoid all ignition sources. Ground all metal containers during 

storage and handling. Keep material dry. Moisture may affect product quality.

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.

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.

Exposure controls

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.

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

facility and a safety shower.

Individual protection measures

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

protection worn must be compatible with respiratory protection system employed.

Skin protection

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.

Other 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.
