MSDS Number: GTRN-0011 Page 4 of 7
Current Issue Date: December, 2005
RESPIRATORY PROTECTION:
None generally required for adequately ventilated work situations. For accidental release or non-ventilated situations, or
release into 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.
