Potential Health Effects

Primary Routes of Entry: Inhalation

Eye contact

Skin contact

Eyes: Material can cause the following:

Moderate irritation.

burning sensation

tearing

reddening

Skin: May cause sensitization by skin contact.

Material can cause the following:

Moderate irritation.

burning sensation

reddening

Itching

Ingestion: Material can cause the following:

severe irritation of the mouth, throat, and digestive tract

diarrhea

nausea

Vomiting

Abdominal pain

Inhalation: Inhalation of vapor or mist can cause the following:

coughing

irritation of nose, throat, and lungs

tightness in the chest

Shortness of breath

May cause severe allergic respiratory reaction.

Sensitization

Chronic Exposure: Long term exposure to diisocyanates may cause lung damage, including reduced

lung function, which may be permanent.



### 4. FIRST AID MEASURE S

Inhalation: Remove to fresh air. In case of shortness of breath, give oxygen. Immediate medical

attention is required.CR 833

Page 3 of 7 Revision date 03/16/2007 Skin contact: Take off all contaminated clothing immediately. Wash off immediately with soap and

plenty of water. If skin irritation persists, call a physician. Wash contaminated clothing before re

- use.

Do not take clothing home to be laundered.

Eye contact: Rinse immediately with plenty of water for at least 15 minutes. If eye irritation persists,

consult a specialist.

Ingestion: Never give anything by mouth to an unconscious person. Do NOT induce vomiting. Drink

1 or 2 glasses of water. Call a physician immediately. If a person vomits when lying on his back,

place him in the recovery position.

Notes to physician

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

have not been shown to be previously sensitized.



### 5. FIRE

courses. Closed containers may explode when heated or contents contaminated w ith water.

Special protective equipment for fire

- fighters: In the event of fire, wear self

- contained breathing

apparatus.

Further information: Fire residues and contaminated fire extinguishing water must be disposed of in

accordance with local regulation s.

Collect contaminated fire extinguishing water separately. This must not be discharged into drains.

- ventilated place.

Further information:

This material is a potential skin sensitizer. See SECTION 8, Exposure Controls/Personal Protection,

prior to handling.

Eye protection: Safety glasses with side

- shields Eye protection worn must be c ompatible 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): 4H Glove (Trademark of Safety 4 A/S of Denmark)

butyl

- rubber Gloves should be removed and replaced immediately if there is any indication of

degradation or chemical breakthrough. Before removing gloves c lean them with soap and water.

NOTE: Material is a possible skin sensitizer.

Skin and body protection: Protective suit Safety shoes

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 app roved (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.

Hygiene measures: Keep container closed when not in use. Shower or ba the at the end of working.

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

facility and a safety shower.



### Engineering measures: Use local exhaust ventilation with a minimum capture velocity of 100

ft/m in. (0.5 m/sec.) at the point of vapor evolution. Refer to the current edition of Industrial Ventilation:
