Section 3: Hazard Identification
Note
Repeated and prolonged overexposure to the mixture of solvent(s) listed in Section 2 can result in systemic effects including permanent brain, nervous system, liver, and kidney damage. Intentional misuse by deliberately concentrating and inhaling the contents may be harmful or fatal.
Emergency
Overview
Product is beige, medium viscosity mastic with a strong solvent odor.
DANGER: EXTREMELY FLAMMABLE, VAPOR HARMFUL. CONTAINS HEXANE. Vapors can cause flash fire. Vapors may ignite explosively. Prevent buildup of vapors by opening all windows and doors to create cross-ventilation. Keep away from heat, sparks, and open flame. Do not smoke. Extinguish all flames and pilot lights. Turn off stoves, heaters, and sparking electric motors. Keep away from all sources of ignition until all vapors are gone. Keep container tightly closed when not in use. Avoid prolonged breathing of vapor. KEEP OUT OF THE REACH OF CHILDREN.
Routes of Entry
Ingestion: Yes; Inhalation: Yes; Skin: Yes; Eye: Yes
Inhalation
Avoid breathing vapors or mist. May cause headache and dizziness. High vapor concentrations are irritating to the nose, throat, and lungs and can cause systemic effects. Vapors can readily accumulate in confined or poorly ventilated areas.
Ingestion
Ingestion is not a probable route of exposure. Harmful if swallowed.
Skin
Prolonged or repeated skin contact can cause irritaiton.
Eye
Substance may cause severe eye irritation.
Medical Conditions
Aggravated by
Exposure
Pre-existing neurological conditions, skin disorders, and respiratory disease.
Carcinogenicity
IARC: No; NTP: No; OSHA: No
Target Organs
Prolonged or repeated overexposure may cause eye, skin, respiratory system, central nervous system, peripheral nervous system damage.
Section 4: First Aid Measures

 

Epinephrine and other sympathomimetic drugs may initiate cardiac arrhythmias (irregular beating) in persons exposed to high concentrations of hexane (e.g. in enclosed spaces or with deliberate abuse). If used, monitor heart action closely. Consider use of other drugs with less arrhythmogenic potential.
Inhalation
Remove to fresh air. If difficulty persists seek medical attention.
Ingestion
Call poison control center immediately. Follow their specific instructions. Do not induce vomiting.
Skin
Wash with soap and water. Contact a physician if irritation develops or persists.
Eye
Hold eyelids apart and flush with plenty of water for at least 15 minutes. Seek medical attention.
Section 5: Fire-Fighting Measures
Flammability Class
(OSHA)
IB
Flash Point
<0°F; Setaflash
Explosive Range
Lower explosive limit 1.2%; Upper explosive limit 7.5%
Flammable Liquid
Vapors can travel back to the source of ignition. Can form explosive mixtures at temperatures at or above the flashpoint.
Extinguishing Media
Use alcohol foam, carbon dioxide, dry chemical, or ABC dry chemical when fighting fires involving this product.
Hazardous Combustion
Products
Carbon monoxide may be released during combustion.
Fire-Fighting Procedures
Can burn in a fire, releasing toxic vapors. Wear a NIOSH approved self-contained breathing apparatus.
Section 6: Accidental Release Measures
Containment Techniques
Use inert absorbent to dike the spill. Keep away from drains.
Clean-up
If possible pump liquid into an approved container or spread absorbent over spills and shovel (use non-sparking equipment) product/absorbent mixture into an approved container. If product has dried, scrape up and place in an approved container.
Emergency Measures
Isolate hazard area. Keep unnecessary and unprotected personnel from entering area. Wear all appropriate personal protection equipment (PPE) (See Section 8).
Section 7: Handling and Storage
Handling
Open container in well ventilated area. Use only in well-ventilated area. Follow all MSDS/label precautions even after container is emptied. Containers may retain residues and vapors. Avoid prolonged or repeated contact with the skin.
Storage
Keep away from sources of ignition. Do not store above 110°F. Store large quantities in buildings designed and protected for storage of NFPA Class 1-B flammable materials.

Section 11: Toxicological Information
Hexane/Acute
Ingestion of hexane can cause nausea, vomiting, stomach pain, and diarrhea. Hexane can irritate the skin and eyes. Acutely, the most common toxic effects are central nervous system depression and chemical pneumonitis resulting from aspiration into the lungs following ingestion.
Hexane/Chronic
Dermal irritation and central nervous system depression accompanied by peripheral nervous system damage (polyneuropathy) are common traits of sustained overexposure.
