use. Do not take clothing home to be laundered.

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

Ingestion: Drink 1 or 2 glasses of water. IMMEDIATELY see a physician. If vomiting occurs

sponta neously, 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

IRRIT ATING . It may not be advisable to induce vomiting. Possible mucosal damage may

contraindicate the use of gastric lavage.



### 5. FIREFIGHTING MEASURES

Flash point No test data available

Lower explosion limit no data available

Upper explosion limit no data available

Suitable extinguishing media: Use the following extinguishing media when fighting fires involving this

material:

Carbon dioxide (CO2)

Specific hazards during firefighting: 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

gener ated during combustion or decomposition. DO NOT permit water to enter containers. Clos ed

containers may explode when heated or contents contaminated with water.

Special protective equipment for firefighters: In the event of fire, wear self

- contained breathing

apparatus.

Further information: Cool closed containers exposed to fire with water spray.

DO NOT permit water to enter containers.

Remain upwind.

Avoid breathing smoke.

Contain run-off.

Environmental precautions

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

BODIES OF WATER.

Methods for cleaning up

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.

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.

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. Kee p containers tightly closed in a cool, well

ventilated place. Keep material dry. Moisture may affect product quality.

Further information:

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.

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.

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.



### 8. EXPOSURE CONTROLS/PERSONAL PROTECTION

Exposure limit(s)

Exposure limits are listed below, if they exist.

Component Regulation Type of listing Value

Rohm and Haas TWA 0.005 ppm

Rohm and Haas TLV

- C 0.02 ppm

Exposure controls

Engineering measures: Use 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 Gove rnmental Industrial

Hygienists for information on the design, installation, use, and maintenance of exhaust systems.Page 5 of 10 Revision Date 03/28/2013

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):

butyl

- rubber Gloves sh ould be removed and replaced immediately if there is any

indication of degradation or chemical breakthrough. Rinse and remove gloves

imm ediately 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 progr am 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

lim it listed in Exposure Limit Informa tion. Above the exposure limit: Wear a properly fitted

NIOSH a pproved (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.

### 11. TOXICOLOGICAL INFORMATION

Toxicological information on this product or its components appear in this section when such data is

available.

Component:

Acute oral toxicity Low toxicity if swallowed.

Small amounts swallowed incidentally as a result of normal handling

operations are not likely to cause injury; however, swallowing larger

amounts may cause injury.

Swallowing may result in gastrointestinal irritation or ulceration.

Component:

Acute oral toxicity LD50 rat 4,130 mg/kg

Component:

Acute inhalation

toxicity LC50 mouse 6 Hour 0.1 mg/l

Component:

Acute dermal toxicity Prolonged skin contact is unlikely to result in absorption of harmful

amounts.

Component:

Acute dermal toxicity LD50 rabbit > 9,400 mg/kg

Component:

Skin irritation Skin irritation

Prolonged contact may cause severe skin irritation with local redness

and discomfort.

Component:Page 7 of 10 Revision Date 03/28/2013

Eye irritation Eye irritation

May cause severe eye irritation.

May cause moderate corneal injury.

Vapor may cause eye irritation exp erienced as mild discomfort and

redness.

Component:

Sensitisation May cause sensitization by skin contact.

Skin contact may cause an allergic skin reaction.

Animal studies have shown that skin contact with isocyanates may play

a role in respiratory sensitization.

Component:

Sensitisation May cause sensitization by inhalation.

May cause allergic respiratory reaction.

Reexposure to ext remely low isocyanate concentrations may cause

allergic respiratory reactions in individuals already sensitized.

Asthma

- like symptoms may include coughing, difficult breathing and a

feeling of tightness in the chest. Occasionally, breathing difficulties m ay

be life threatening.

Effects may be delayed.

Component:

Subchronic toxicity Based on available data, repeated exposures are not anticipated to

cause additional significant adverse effects.

Component:

Carcinogenicity : An oral study in which high doses of TDI were reported to cause cancer in

animals has been found to contain numerous deficiencies which compromise the validity of the

study. TDI did not cause cancer in laboratory animals exposed by inhala tion, the most likely route

of exposure.

Component:

Reproductive toxicity

In animal studies, TDI has been shown not to interfere with reproduction.

Component:

Teratogenicity

TDI did not cause birth defects in laboratory animals. Slight effects were observed in the fetus but only

at doses which caused toxic effects to the mother.

Component:

Mutagenicity

In vitro genetic toxicity studies were negative in some cases and positive in other cases. Animal

genetic toxicity studies were negative. Results of a Drosophila study were reported to be weakly

posi tive; however, these positive findings are believed to be due to degradation of TDI in the

solvent deliv ery vehicle.
