3. Hazards Identification - Continued
Skin Hazards
May cause skin irritation and contact dermatitis upon prolonged contact. Dermal sensitization may occur from repeated
and prolonged exposures.
Ingestion Hazards
May be harmful if swallowed. May cause gastric distress, vomiting and diarrhea.
Inhalation Hazards
Exposure to vapors may cause respiratory tract irritation. Inhalation of vapors or mists may cause central nervous system
depression, light-headedness, headache, nausea and loss of coordination.
Chronic/Carcinogenicity Effects
This product or one of its ingredients present at 0.1% or more is listed as a carcinogen by NTP, IARC or OSHA. See
Section 11 (Toxicological Information) for more details.
4. First Aid Measures
Eye
In case of contact, hold eyelids apart and immediately flush eyes with plenty of water for at least 15 minutes. Get medical
attention immediately if irritation develops and persists.
Skin
Remove contaminated clothing and shoes. Wash affected areas with soap and water.
Ingestion
Get medical attention immediately. DO NOT INDUCE VOMITING. Never give anything by mouth to an unconscious
victim. Call a physician or poison control center immediately.
Inhalation
Remove the person from the contaminated area to fresh air. If breathing is difficult, give oxygen. Get medical attention
immediately.
5. Fire Fighting Measures
Flash Point: 120 癋
Flash Point Method: Setaflash
Lower Explosive Limit: 0.9
Upper Explosive Limit: 6.0
Fire And Explosion Hazards
Combustible Liquid. Vapors are heavier than air and may spread long distances and ignite.Thermal decomposition
(burning) may release irritating, corrosive and/or toxic gases, vapors and fumes.
Extinguishing Media
Chemical foam, carbon dioxide (CO2), or dry chemical. Do not use direct stream of water.
Fire Fighting Instructions
Firefighters should wear self-contained breathing apparatus and full protective gear.
6. Accidental Release Measures
Collect and dispose in accordance with applicable regulations.
7. Handling And Storage
Handling And Storage Precautions
Keep away from ignition sources. Keep containers tightly closed. Store in a cool, dry, well-ventilated area. Do not handle
or store near heat, sparks, flame, strong oxidants or strong acids. Use only with adequate ventilation.

8. Exposure Controls/Personal Protection
Engineering Controls
Use with adequate general and local exhaust ventilation. When used outdoors, stay well away from building air intakes or
close and seal the intakes to prevent product from entering building.
Eye/Face Protection
Safety glasses with side shields or goggles recommended.
Skin Protection
Use with chemical-protective gloves to prevent skin contact.
Respiratory Protection
The level of respiratory protection needed should be based on the evaluation of chemical exposures by a health or safety
professional. If required, use a NIOSH-approved air purifying respirator with organic vapor cartridge and particulate filter
or supplied air respirator.
