Appendix
EYE PROTECTION:
For normal conditions, wear safety glasses. Where there is reasonable probability of liquid contact,
wear chemical safety goggles.
RESPIRATORY PROTECTION:
None generally required for adequately ventilated work situations. For accidental release or non-
ventilated situations, or release into a confined space, where the concentration may be above the PEL
of 1,000 ppm, use a self-contained, NIOSH-approved breathing apparatus or supplied air respirator. For
escape: use the former or a NIOSH-approved gas mask with organic vapor canister.
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.
