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.
