MSDS

Note: See Section 8 for Personal Protective Equipment for Spills.
Handling: Use with adequate ventilation. Product evolves acetic acid (HOAc) when exposed to water or humid air.
Provide ventilation during use to control HOAc within exposure guidelines or use respiratory protection. Avoid eye contact.
Avoid breathing vapor, mist, dust, or fumes. Keep container closed. Avoid skin contact.
Storage:
Use reasonable care and store away from oxidizing materials. Keep container closed and store away from water
or moisture. This material in its finely divided form presents an explosion hazard. Follow NFPA 654 (for chemical dusts) or
484 (for metal dusts) as appropriate for managing dust hazards to minimize secondary explosion potential.
Important: Listed Permissible Exposure Levels (PEL) are from the U.S. Dept. of Labor OSHA Final Rule Limits (CFR 29 1910.1000); these limits may vary
between states.
Note: An employee's skin exposure to substances having a "YES" in the "SKIN" column in the table above shall be prevented or reduced to the extent
necessary under the circumstances through the use of gloves, coveralls, goggles or other appropriate personal protective equipment, engineering controls or work
practices.
Exposure Notes:
Consult local authorities for acceptable provincial values.
Acetic acid is formed upon contact with water or humid air. Provide adequate ventilation to control exposures within
guidelines of OSHA PEL: TWA 10 ppm and ACGIH TLV: TWA 10 ppm, STEL 15 ppm.
Precautionary Measures: Avoid eye contact. Avoid breathing vapor, mist, dust, or fumes. Keep container closed. Avoid
skin contact. Use reasonable care.
Comments: Product evolves acetic acid (HOAc) when exposed to water or humid air. Provide ventilation during use to
control HOAc within exposure guidelines or use respiratory protection.
Note: These precautions are for room temperature handling. Use at elevated temperature or aerosol/spray applications
may require added precautions.
Engineering Controls: Local Ventilation: Recommended.
General Ventilation: Recommended.
Respiratory Protection: Personal Protective Equipment for Routine Handling:
----------------------------------------------------------------------------------
Inhalation:
Use respiratory protection unless adequate local exhaust ventilation is provided or exposure assessment demonstrates
that exposures are within recommended exposure guidelines. IH personnel can assist in judging the adequacy of existing
engineering controls.
Suitable Respirator:
Respiratory protection is not needed under ambient conditions. If vapor is generated when material is heated or handled,
the following is advised. General and local exhaust ventilation is recommended to maintain vapor exposures below
recommended limits. Where concentrations are above recommended limits or are unknown, appropriate respiratory
protection should be worn. Follow OSHA respirator regulations (29 CFR 1910.134) and use NIOSH/MSHA approved
respirators.
