Principle Routes of Exposure

INHALATION of vapor or spray mist. EYE or SKIN contact with the product, vapor or spray mist. Continued on page 2 B60V2Z70 page 2 EFFECTS OF OVEREXPOSUR: EYES: Irritation. SKIN: Prolonged or repeated exposure may cause irritation. ( INHALATION: Irritation of the upper respiratory system. May cause nervous system depression. Extreme overexposure may result in unconsciousness and possibly death. SIGNS AND SYMPTOMS OF OVEREXPOSURE Headache, dizziness, nausea, and loss of coordination are indications of excessive exposure to vapors or spray mists. Redness and itching or burning sensation may indicate eye or excessive skin exposure.

Medical Conditions Generally Aggravated by Exposure

BY EXPOSURE May cause allergic skin reaction in susceptible persons or skin sensitization.

Health hazards

Ethylbenzene is classified by IARC as possibly carcinogenic ‘to humans _, (2B) based on inadequate evidence ( in humans and sufficient evidence in laboratory animals. to high Lifetime inhalation exposure of rats and mice ethylbenzene concentrations resulted in increases in certain types of cancer, including kidney tumors in rats and lung and liver tumors in mice. These effects were not observed in animals exposed to lower concentrations. There is no evidence that ethylbenzene causes cancer in humans. Prolonged overexposure to solvent ingredients in Section 2 may cause adverse effects to the liver, urinary and reproductive systems. Reports have associated repeated and prolonged overexposure to solvents with permanent brain and nervous system damage.

Wash hands after using. This coating may contain materials classified as nuisance particulates (listed "as Dust" in Section 2) which may be present at hazardous levels only during sanding or abrading of the dried film. If no specific dusts are listed in Section 2, the applicable limits for nuisance dusts are ACGIH TLV 10 mg/m3 (total dust), 3 mg/m3 (respirable fraction), OSHA PEL 15 mg/m3 os, (total dust), 5 mg/m3 (respirable fraction). VENTILATION Local exhaust preferable. General exhaust acceptable if the exposure to materials in Section 2 is maintained below applicable exposure limits. Refer to OSHA Standards 1910.94, 1910.107, 1910.108. RESPIRATORY PROTECTION If personal exposure cannot be controlled below applicable limits by ventilation, wear a properly fitted organic vapor/particulate respirator approved by NIOSH/MSHA for protection against materials in Section 2. When sanding or abrading the dried film, wear a dust/mist respirator approved by NIOSH/MSHA for dust which may be generated from this product, underlying paint, or the abrasive. PROTECTIVE GLOVES Wear gloves which are recommended by glove supplier for protection against materials in Section 2. EYE PROTECTION Wear safety spectacles with unperforated sideshields.
