SECTION V- HEALTH HAZARD DATA
Overexposure Effects:
Acute Effects:
EYES: Contact with eyes can cause an immediate severe reaction and may result in loss of functional vision. May
cause delayed keratitis.
SKIN: Contact with skin can cause irritation, (minor itching, burning and/or redness), Dermatitis, defatting may be
readily absorbed through the skin.
INHALATION: Inhalation of vapors can cause nasal and respiratory irritation, dizziness, weakness, fatigue, nau-
sea, headache, possible unconsciousness and/or asphyxiation. Aspiration ofmaterial into lungs may result in chem-
ical pneumonitis which can be fatal.
INDIGESTION: Ingestion can cause gastrointestinal irritation, nausea, vomiting, diarrhea.

Mutagen: Yes No X
Routes of Exposure: Skin, Inhalation
First Aid:
Inhalation - If inhaled, remove victim from exposure to a well-ventilated area. Make them comfortably warm, but not
hot. Use oxygen or artificial respiration as required. Consult a physician.
Skin - For skin contact, wash promptly with excess soap and water. Consult a physician if irritation or redness occurs.

SECTION VIII - PROTECTION INFORMATION
Respiratory Protection: If component TLV limits are exceeded, use NIOSH/OSHA approved respirator to remove vapors.
Use an air-supplied respirator if necessary.
Ventilation: Use adequate ventilation in volume and pattern to keep TLV/PEL below recommended levels. Explosion-proof
ventilation may be necessary.
Skin: Prevent exposure from liquid or spray by use of rubber gloves, permeation-resistant clothing, footwear; products may
irritate skin or be absorbed through the skin.
Eye Protection: Safety glasses or goggles with splash guards or side shields.
Other Protective Equipment: Wear protective clothing as required to prevent all direct contact.
