### 4. FIRST AID MEASURE S

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.

Inges tion: 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 isoc yanates, 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 MEASURE S

Flash point 5 °C ( 41 °F )

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 to xic 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 ev ent 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 RELEAS E 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.

M ATERIAL 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 contaminate d clothing before re

- use.

Do not take clothing home to be laundered.CR 857

Page 4 of 8 Revision date 04/26/2007 

### 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 pe rsonnel 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 conta iner 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 op erations. 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 Protect ion, 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 preparatio n is being

used.

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, well

ventilated 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 protect ion 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 adequat e 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

chemi cal 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 possi ble, 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 condit ions 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 breath ing 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 an d 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 Recommen ded Practice published by the American Conference of

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