PERSONAL PROTECTION
ENGINEERING CONTROLS: Use process enclosures, local exhaust ventilation, or other engineering controls to control airborne
levels below recommended exposure limits. Prevent build-up of vapors by opening all doors and windows to achieve cross-
ventilation.
RESPIRATORY PROTECTION: A respiratory protection program that meets OSHA 1910.134 and ANSI Z88.2 requirements must
be followed whenever workplace conditions warrant a respirator's use.
SKIN PROTECTION: Use gloves to prevent prolonged skin contact. Nitrile or Neoprene gloves may afford adequate skin
protection.
EYE PROTECTION: Use safety eyewear designed to protect against splash of liquids.
OTHER PROTECTIVE EQUIPMENT: Refer to safety supervisor or industrial hygienist for further guidance regarding types of
personal protective equipment and their applications. Refer to safety supervisor or industrial hygienist for further information
regarding personal protective equipment and its application.
HYGIENIC PRACTICES: Wash thoroughly with soap and water before eating, drinking or smoking. Remove contaminated clothing
immediately and launder before reuse.
