    Eye Contact: May lead to irritation.

    Skin Contact: May lead to dermatitis.

    Ingestion: May lead to vomiting.

Carcinogenicity (NTP, IARC, OSHA): Components of this product are not listed as known human carcinogens.

Trace amounts of ethyl benzene and naphthalene, as components of the aromatic and mineral spirits, are listed by

IARC as 2B (possible human carcinogen).

Signs and Symptoms of Exposure: Overexposure may lead to dizziness, headaches, dermatitis and eye irritation.

Medical Conditions Aggravated by Exposure: The aromatic hydrocarbon, (a component of this blend), contains

xylene. Xylene may be harmful to the human fetus based on positive test results with laboratory animals. Health

studies have shown that many petroleum hydrocarbons pose potential health risks that vary from person to person.

Minimize exposure to liquids, vapors, mists or fumes.



Emergency and First Aid Procedures:

      For Skin Contact: Flush with large volume of water for at least 15 minutes.

                        Get immediate medical attention if necessary.

      For Inhalation:   Remove to fresh air. Get immediate medical attention.

      For Eye Contact: Flush with large volume of water for at least 15 minutes. Get immediate medical attention.

      For Ingestion:     Get immediate medical attention. Do not induce vomiting.



SECTION 7: PRECAUTIONS FOR SAFE HANDLING AND USE/REGULATORY INFORMATION

Steps to be taken in case material is released or spilled:

(Minor Spills): Eliminate sources of ignition. Absorb material with ground clay, vermiculite or similar absorbent

materials, then place into containers for removal.

(Major Spills): Eliminate sources of ignition. Dike and contain spill. 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 Regulation 40CFR302 (CERCLA) Section

102 and EPA Regulation 40CFR372 (SARA) 313. This product contains approximately 1.25% cumene, 1.25% xylene

and 5.25% 1,2,4-trimethylbenzene. Ethyl benzene and naphthalene are present at less than 1.0%.

Product contains components which may be further regulated by state 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 (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 not
