### 4. FIRST AID MEASURES

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.

Ing estion: 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 is ocyanates, 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 MEASU RES

Flash point 4 °C ( 39.92 °F ) SETAFLASH CLOSED CUP

Ignition temperature 426.0 °C ( 798.80 °F ) Ethyl acetate

Lower explosion limit 2.20 %(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.

Fur ther 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 REL EASE 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.COREACTANT CT

Page 4 of 9 Revision date 08/27/2004 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 STOR AGE

Handling

Vapors can be evolved when material is heated during processing operations. See SECTI ON 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 h andling. 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 equippe d with automatic

sprinklers. Store out of direct sunlight in a cool place. Keep containers tightly closed in a cool, well

ventilated place. Avoid all ignition sources. Ground all metal containers during storage and handling.

Keep material dry. Moistu re 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

g love(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 (Trad emark 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 protec tion: 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 list ed 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 emerg ency 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

veloci ty 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.
