### OSHA Hazard Communication Standard

This product is a "Hazardous Chemical" as defined by the OSHA Hazard Communication Standard, 29

CFR 1910.1200.

# Material Safety Data Sheet

The Dow Chemical CompanyProduct Name: SPECFLEX* NF 749 Polyol DA Issue Date: 09/07/2012

Page 2 of 10 Inhalation: At roo m temperature, exposure to vapor is minimal due to low volatility; single exposure is

not likely to be hazardous. Vapor from heated material may cause respiratory irritation.

Ingestion: 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.

Aspiration hazard: Based on physical properties, not likely to be an aspi ration hazard.

Cancer Information: Findings from a chronic diethanolamine skin painting study by NTP include liver

and kidney tumors in mice; no tumors were observed in rats. Mechanistic studies indicate that tumor

formation is of questionable relevance to humans.

## 4. First

- aid measures

Description of first aid measures

General advice: If potential for exposure exists refer to Section 8 for specific personal protective

equipment.

Inhalation: Move person to fresh air; if effects occur, consult a physician.

Skin Contact: Wash skin with plenty of water.

Eye Contact: Flush eyes thoroughly with water for several minutes. Remove contact lenses after the

initial 1

- 2 minutes and continue flushing for several additional minutes. If effects occur, consult a

physician, preferably an ophthalmologist. Suitable emergency eye wash facility should be available in

work area.

Ingestion: If swallowed, seek medical attention. Do not induce vomiting unless directed to do so by

medical personnel.



### Most important symptoms and effects, both acute and delayed

Aside from the information found under Description of first aid measures (above) and Indication of

immediate medical attention and special treatment needed (below), no additional symptoms and

effects are anticipated.



### Indication of immediate medical atte ntion and special treatment needed

No specific antidote. Treatment of exposure should be directed at the control of symptoms and the

clinical condition of the patient.



## 5. Fire Fighting Measure s

Suitable extinguishing media

Water fog or fine spray. Dry chemical fire extinguishers. Carbon dioxide fire extinguishers. Foam.

Alcohol resistant foams (ATC type) are preferred. General purpose synthetic foams (including AFFF)

or protein foams may function, but will be less effective.

Extinguishing Media to Avoid: Do not use direct water stre am. May spread fire.



### Special hazards arising from the substance or mixture 

## 3. Composition InformationProduct Name: SPECFLEX* NF 749 Polyol DA Issue Date: 09/07/2012

Page 3 of 10 Hazardous Combustion Products: During a fire, smoke may contain th e original material in addition

to combustion products of varying composition which may be toxic and/or irritating. Combustion

products may include and are not limited to: Carbon monoxide. Carbon dioxide.

Unusual Fire and Explosion Hazards: Container may rupture from gas generation in a fire situation.

Violent steam generation or eruption may occur upon application of direct water stream to hot liquids.



### Advice for firefighters

Fire Fighting Procedures: Keep people away. Isolate fire and deny unnecessary entry. Use water

spray to cool fire exposed containers and fire affected zone until fire is ou t and danger of reignition has

passed. Fight fire from protected location or safe distance. Consider the use of unmanned hose

holders or monitor nozzles. Immediately withdraw all personnel from the area in case of rising sound

from venting sa fety device or discoloration of the container. Do not use direct water stream. May

spread fire. Move container from fire area if this is possible without hazard. Burning liquids may be

moved by flushing with water to protect personnel and minimize property damage. Contain fire water

run

- off if possible. Fire water run

- off, if not contained, may cause environmental damage. Review the

"Accidental Release Measures" and the "Ecological Information" sections of this (M)SDS.

Special Protective Equipment for Firefighters: Wear positive

- pressure self

- contained breathing

apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet, coat, trousers,

boots, and gloves). Avoid contact with this material during fire fighting operations. If contact is likely,

change to full chemical resistant fire fighting clothing with self

- contained breathing apparatus. If this is

not available, wear full chemical res istant clothing with self

- contained breathing apparatus and fight fire

from a remote location. For protective equipment in post

- fire or non

- fire clean

- up situations, refer to

the relevant sections.



## 6. Accidental Release Measures

Personal precautions, protective equipment and emergency procedures: Isolate area. Refer to

Section 7, Handling, for additional precautionary measures. Keep unnecessary and unprotected

personnel from entering the area. Spilled material may cause a slipping hazard. Use appropriate

safety equipment. For additional info rmation, refer to Section 8, Exposure Controls and Personal

Protection.

Environmental precautions : Prevent from entering into soil, ditches, sewers, waterways and/or

groundwater. See S ection 12, Ecological Information.

Methods and materials for containment and cleaning up : Contain spilled material if possi ble.

Absorb with materials such as: Dirt. Sand. Sawdust. Collect in suitable and properly labeled

containers. Wash the spill site with water

. See Section 13, Disposal Considerations, for additional

information.



## 7. Handling and Storage

Handling

General Handling: Avoid contact with eyes. Wash thoroughly after handling. Keep container closed.

This material is hygroscopic in nature. See Section 8, EXPOSURE CONTROLS AND PERSONAL

PROTECTION.

Other Precautions: Spills of these organic materials on hot fibrous insulations may lead to lowering of

the autoignition temperatures possibly resulting in spontaneous combustion.



### Storage

Protect from atmospheric moisture. Store in a dry place. Avoid prolonged exposure to heat and air.

Store in the following material(s): Carbon steel. Stainless steel. Polypropylene. Polyethylene

- lined

container. Teflon. Glass

- lined container. Aluminum. Plasite 3066 lined container. Plasite 3070 lined

container. 316 stainless steel. See Section 10 for more specific information.

## 8. Exposure Controls / Personal Protection

Exposure Limits

Component List Type Value

| N,N

- Diethanolamine ACGIH TWA

Inhalable

fraction and

vapor. 1 mg/m3 SKIN

A "skin" notation following the inhalation exposure gu ideline refers to the potential for dermal

absorption of the material including mucous membranes and the eyes either by contact with vapors or

by direct skin contact.

It is intended to alert the reader that inhalation may not be the only route of exposure and that

measures to minimize dermal exposures should be considered.



### Personal Protection

Eye/Face Prot ection: Use safety glasses (with side shields).

Skin Protection: No precautions other than clean body

- covering clothing should be needed.

Hand protection: Chemical protective gloves should not be needed when handl ing this

material. Consistent with general hygienic practice for any material, skin contact should be

minimized.

Respiratory Protection: Respiratory protection should be worn when there is a potential to exceed

the exposure li mit requirements or guidelines. If there are no applicable exposure limit requirements

or guidelines, wear respiratory protection when adverse effects, such as respiratory irritation or

discomfort have been experienced, or where indicated by your risk ass essment process. For most

conditions, no respiratory protection should be needed; however, if handling at elevated temperatures

without sufficient ventilation, use an approved air

- purifying respirator. The following should be

effective types of air

- purifying respirators: Organic vapor cartridge.

Ingestion: Use good personal hygiene. Do not consume or store food in the work area. Wash hands

before smoking or eating.



### Engineering Controls

Ventilation: Use local exhaust ventilation, or other engineering controls to maintain airborne levels

below exposure limit requir ements or guidelines. If there are no applicable exposure limit

requirements or guidelines, general ventilation should be sufficient for most operations. Local exhaust

ventilation may be necessary for some operations.
