ADDITIONAL RECOMMENDATIONS: Where contact with liquid is likely, such as in a spill or leak,
impervious boots and clothing should be worn. High dose-level warning signs are recommended for areas
of principle exposure. Provide eyewash stations and quick-drench shower facilities at convenient locations.
For tank cleaning operations, see OSHA regulations, 29 CFR 1910.132 and 29 CFR 1910.133.

10. STABILITY AND REACTIVITY
NORMALLY STABLE (CONDITIONS TO AVOID):
The product is stable.
Do not mix with oxygen or air above atmospheric pressure. Any source of high temperature, such as lighted
cigarettes, flames, hot spots or welding may yield toxic and/or corrosive decomposition products.
INCOMPATIBILITIES:
Under specific conditions: e.g. very high temperatures and/or appropriate pressures – Freshly abraded aluminum
surfaces may cause strong exothermic reaction. Chemically active metals: potassium, calcium, powdered aluminum,
magnesium and zinc.
