3. Hazards Identification - Continued
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.

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
Airborne exposures to hazardous dusts or mists may be generated by spraying, sanding or grinding.
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.
