3. HAZARDS IDENTIFICATION
*** EMERGENCY OVERVIEW ***: Amber Liquid, with Ammonia odor. Harmful if inhaled. Harmful if
absorbed through skin. May cause skin and eye burns. May cause allergic skin reaction. May cause allergic respiratory
reaction. Causes respiratory tract irritation.
EFFECTS OF OVEREXPOSURE - EYE CONTACT: May be corrosive to eyes; contact may cause eye burns.
Eye contact may cause severe eye damage, including vision disturbances, corneal damage, and blindness.
EFFECTS OF OVEREXPOSURE - SKIN CONTACT: May be absorbed through the skin in harmful amounts.
May be corrosive to skin; contact may cause skin burns. May cause skin sensitization. May cause allergic skin reaction.
May cause dermatitis.
EFFECTS OF OVEREXPOSURE - INHALATION: Possible irritation of the respiratory system can occur causing
a variety of symptoms such as dryness of the throat, tightness of the chest, and shortness of breath. May cause headache
and nausea. Vapors may cause irritation of nose, throat, and upper respiratory tract. Inhalation may cause temporary
blurring of vision. May cause respiratory sensitization. May cause allergic respiratory reaction. May cause lung
damage.
EFFECTS OF OVEREXPOSURE - INGESTION: Harmful if swallowed. Ingestion is not an expected route of
entry in industrial or commercial uses.
EFFECTS OF OVEREXPOSURE - CHRONIC HAZARDS: May cause conjunctivitis or other adverse eye effects.
May cause skin sensitization. May cause respiratory sensitization. Extremely high vapor concentrations may cause lung
damage. May cause liver or kidney damage. Chronic skin contact may cause dermatitis.

PRIMARY ROUTE(S) OF ENTRY: Skin Contact, Skin Absorption, Inhalation, Ingestion, Eye Contact
4. FIRST AID MEASURES
FIRST AID - EYE CONTACT: Flush eyes immediately with large amount of water for at least 15 minutes holding
eyelids open while flushing. Get prompt medical attention.
FIRST AID - SKIN CONTACT: Flush contaminated skin with large amounts of water while removing contaminated
clothing. Wash affected skin areas with soap and water. Get medical attention if symptoms occur.
FIRST AID - INHALATION: Move person to fresh air. Restore and support continued breathing. If breathing is
difficult, give oxygen. Get immediate medical attention.
FIRST AID - INGESTION: If swallowed, do not induce vomiting. Give victim one or two glasses of water or milk.
Call a physician or poison control center immediately for further instructions. Never give anything by mouth if victim is
rapidly losing consciousness, unconscious or convulsing.
5. FIRE-FIGHTING MEASURES
FLASH POINT: 201 掳F, 93 掳C LOWER EXPLOSIVE LIMIT (%): Not Applicable
Setaflash Closed Cup UPPER EXPLOSIVE LIMIT (%): Not Applicable
AUTOIGNITION TEMPERATURE: N.D.
EXTINGUISHING MEDIA: Carbon Dioxide, Dry Chemical, Foam, Water Fog
UNUSUAL FIRE AND EXPLOSION HAZARDS: Keep containers tightly closed. Closed containers may rupture
when exposed to extreme heat. Use water spray to keep fire exposed containers cool. During a fire, irritating and/or
toxic gases and particulate may be generated by thermal decomposition or combustion.
SPECIAL FIREFIGHTING PROCEDURES: Wear full firefighting protective clothing, including self-contained
breathing apparatus (SCBA). If water is used, fog nozzles are preferable.
6. ACCIDENTAL RELEASE MEASURES
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Keep non-essential personnel a
safe distance away from the spill area. Avoid breathing vapors. Use self-contained breathing equipment. Notify
appropriate authorities if necessary. Avoid contact. Before attempting cleanup, refer to hazard caution information in
other sections of the MSDS form. Scoop spilled material into an appropriate container for proper disposal. (If necessary,
use inert absorbent material to aid in containing the spill).
7. HANDLING AND STORAGE
HANDLING: Keep closure tight and container upright to prevent leakage. Avoid skin and eye contact. Wash
thoroughly after handling. Avoid breathing of vapor or spray mists. Do not handle until all safety precautions have been
read and understood. Empty containers should not be re-used. Use with adequate ventilation.
STORAGE: Store only in well-ventilated areas. Keep container closed when not in use.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
ENGINEERING CONTROLS: Sufficient ventilation in pattern and volume should be provided in order to maintain
air contaminant levels below recommended exposure limits.
RESPIRATORY PROTECTION: Use a NIOSH approved air-purifying organic vapor respirator if occupational
limits are exceeded. For emergency situations, confined space use, or other conditions where exposure limits may be

Product: THERMALBOND 4951 B, Effective Date: 09/28/2007
greatly exceeded, use an approved air-supplied respirator. Observe OSHA regulations (29CFR 1910.134) for respirator
use.
SKIN PROTECTION: Use neoprene, nitrile, or rubber gloves to prevent skin contact.
EYE PROTECTION: Use safety eyewear including safety glasses with side shields and chemical goggles where
splashing may occur.
OTHER PROTECTIVE EQUIPMENT: Remove and wash contaminated clothing before reuse.
HYGIENIC PRACTICES: Wash hands before eating, smoking, or using toilet facility. Food or beverages should not
be consumed anywhere this product is handled or stored. Wash thoroughly after handling.
