SECTION 6: ACCIDENTAL RELEASE MEASURES
?Personal Precautions: An appropriate NIOSH/MSHA approved respirator should be used if a mist, vapor or dust is
generated. Wear suitable gloves and eye/face protection. Do not touch damaged containers or spilled material unless
wearing appropriate protective clothing.
?Environmental Precautions: Minimize contamination of drains, surface and ground waters.
?Procedures for Spill/Leak Clean-up: Sweep or shovel solids. For liquid spills, neutralization is not required.
Contain spill. Absorb or cover with dry earth, sand or other noncombustible material and transfer to containers for
disposal. Dispose as any grease or oily material in compliance with Federal, State, and/or Local requirements.
Refer to Section 8 for additional personal protection information.
Refer to Section 13 for disposal considerations.
SECTION 7: HANDLING AND STORAGE
?Handling: Handle in accordance with good hygiene and safety procedures. Avoid contact with eyes, skin, and
clothing. Wash thoroughly after handling. Prevent formation of dust.
Since empty containers contain product residue and can be dangerous, follow all hazard warnings and
precautions even after container is emptied. Keep away from sources of ignition.
?Storage: Keep away from possible contact with incompatible substances.
Store in acid resistant vessels such as stainless steel, aluminum, or steel coated with resin lining
such as Lithcote LC-19 or Kanigen.
Do not store near sources of ignition.
?Specific use(s): Follow bulk handling and storage procedures as noted above.
Refer to Section 6 for clean-up of spillages.
Refer to Section 13 for disposal considerations.
SECTION 8: EXPOSURE CONTROLS AND PERSONAL PROTECTION
?General Precautions: Good industrial hygiene practices should be followed.
Avoid breathing (heated) vapors. Avoid eye and skin contact.
?Exposure Limit Values: Not established.
?Exposure Controls:
Engineering Controls: Ventilation: Local exhaust - preferred
Mechanical - may be necessary if working at elevated temperatures or in enclosed areas.

Personal Protective Equipment:
Eye - Goggles or face shield with goggles, dependent upon potential exposure
Skin - Protective gloves: Rubber or plastic
Dependent upon degree of potential exposure, additional personal protective
equipment may be required, such as chemical boots and full protective clothing.
Inhalation - None required for ambient temperature, although an appropriate NIOSH/MSHA approved air-purifying
respirator should be used if a mist, vapor or dust is generated. A NIOSH/MSHA approved self-contained
breathing apparatus or air-supplied respirator is recommended if the concentration exceeds the capacity
of cartridge respirator. WARNING: Air purifying respirators do not protect workers in oxygendeficient
atmospheres
Other Controls: Boots, eye wash fountain, safety shower, apron, protective clothing.
?Environmental Exposure Controls: Contact Procter and Gamble for specific Community information.
