Emergency Overview
NI
Signs & Symptoms of Short-Term (Acute) Exposure
Excessive vapor concentration in air, especially in confined spaces, may cause asphyxiation. Excessive inhalation of
vapors can cause nasal, throat and respiratory irritation, dizziness, weakness, fatigue, nausea, headache and possible
unconsciousness. Eye contact causes irritation, redness, tearing, blurred vision. Eye contact with liquid or vapor causes
severe irritation, redness, tearing, blurred vision. Vapors may cause severe eye irritation, redness, tearing and blurred
vision. Prolonged skin contact may lead to extraction of natural oils with resultant dry skin, cracking, irritation and dermititis.
Swallowing may cause gastrointestinal irritation, nausea, vomiting and diarrhea. Notice: intentional misuse by deliberately
concentrating and inhaling the contents maybe harmful or fatal. Reports have associated repeated and prolonged
occupational overexposure to solvents with permanent brain and nervous system damage.
Effects of Long-Term (Chronic) Exposure
Health studies have shown that many solvents pose potential human health risks which may vary from person to person.
As a precaution, exposure to liquids and vapors should be minimized. -Prolonged or continuous inhalation of vapors may
result in delayed lung damage. -Repeated or prolonged inhalation of vapor may cause liver and kidney damage. -Repeated
inhalation of vapor in high concentration can change the blood picture.

5 FIRE FIGHTING MEASURES
Extinguishing Media
Chemical powder, carbonic acid - co 2, foam.
Basic Fire Fighting Procedures
Water spray may be ineffective. For extinguishing larger fires or inside buildings, a self-contained breathing apparatus is
recommended to protect firefighters from any hazardous combustion products.
Unusual Fire & Explosion Hazards
Water may be used to cool endangered containers. Keep containers tightly closed.
