disperse or exhaust vapors, in accordance with good industrial hygiene practice. Warning! A motor could be an ignition source and
could cause flammable gases or vapors in the spill area to burn or explode. Contain spill. For larger spills, cover drains and build
dikes to prevent entry into sewer systems or bodies of water. Working from around the edges of the spill inward, cover with
bentonite, vermiculite, or commercially available inorganic absorbent material. Mix in sufficient absorbent until it appears dry.
Collect as much of the spilled material as possible. Collect the resulting residue containing solution. Place in a closed container
approved for transportation by appropriate authorities. Dispose of collected material as soon as possible.

In the event of a release of this material, the user should determine if the release qualifies as reportable according to
local, state, and federal regulations.

National Fire Protection Association (NFPA) hazard ratings are designed for use by emergency response personnel to address the hazards that are
presented by short-term, acute exposure to a material under conditions of fire, spill, or similar emergencies. Hazard ratings are primarily based on the
inherent physical and toxic properties of the material but also include the toxic properties of combustion or decomposition products that are known to
be generated in significant quantities.


Revision Changes:
Copyright was modified.
Section 2: Ingredient table was modified.
Section 15: California proposition 65 ingredient information was modified.
Section 3: Carcinogenicity table was modified.
