3. Hazards Identification
EMERGENCY OVERVIEW
Although this product is not classified as irritant, it has been known for many years that operators working in confined
areas can experience transient eye and respiratory irritation due to the small amount of acetic acid evolved during the
curing cycle. This can be avoided by employing good standards of industrial hygiene and operating in a well
ventilated area. An exposure risk to acetic acid and possibly silica dust exists from hydrolysis and combustion.
For short and long term exposure effects see Section 11 Toxicological data
