PERSONAL PROTECTION
ENGINEERING CONTROLS: Use process enclosures, local exhaust ventilation, or other engineering controls to control airborne
levels below recommended exposure limits. Provide general dilution of local exhaust ventilation in volume and pattern to keep TLV of
hazardous ingredients below acceptable 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 impervious gloves to prevent skin contact and absorption of this material through the skin.
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.
HYGIENIC PRACTICES: Wash thoroughly with soap and water before eating, drinking or smoking. Remove contaminated clothing
immediately and launder before reuse.
