SECTION 7: PRECAUTIONS FOR SAFE HANDLING AND USE/REGULATORY INFORMATION
Steps to be taken in case material is released or spilled:
(Minor Spills): Absorb material with ground clay, vermiculite, or similar absorbent material, then place into
containers for removal.
(Major Spills): Dike and contain spill. Eliminate potential sources of ignition, and shut off source of spill if
possible. Remove liquid by chemical vacuum, absorbent, or other safe and approved method and place into
containers for legal disposal. Flush area with water to remove residue, and remove flushed solutions as above.
(Waste Disposal Method): Dispose of all waste in accordance with federal, state and local regulations.
Regulatory Information: This information may be useful in complying with EPA Regulation 40CFR302
(CERCLA)
Section 102 and EPA Regulation 40CFR372 (SARA 313): This product contains approximately 0.1% cumene,
0.2% xylene and 1.8% 1,2,4-trimethylbenzene.
Product may contain components which are further regulated by state and/or local agencies (e.g. benzene and
CA65C) - Consult Appropriate Agencies.
Precautions to be Taken in Handling and Storing: Ventilation in work area should be sufficient to maintain
atmosphere with vapor level below lowest listed TLV in Section 2. If TLV's are exceeded, use a respirator with
appropriate NIOSH approved cartridges or supplied air equipment. Keep containers closed when not in use.
Combustible liquid - empty containers can be hazardous and contain explosive vapors.
HMIS: Health Hazard: 2 Flammability: 2 Reactivity: 0 Personal Protection: B
SECTION 8: CONTROL MEASURES
Respiratory Protection: Needed if TLV's in Section 2 are exceeded. Use supplied air equipment or respirators
with proper NIOSH approved cartridges.
Ventilation: Local and mechanical exhaust recommended. Avoid open electrical sources near product vapor
areas.
Protective Gloves: Impervious or chemical resistant gloves recommended (consult safety equipment supplier).
Eye Protection: Chemical splash goggles recommended to protect against potential eye contact.
Other Protective Clothing and Equipment: Safety shoes and aprons recommended.
Work and Hygiene Practices: Do not take internally. Avoid skin contact and wash skin after using products. Do
