Initially minimize area affected by the spill or leak. Block any potential
routes to water systems (e.g., sewers, streams, lakes, etc.). Based on the
product’s toxicological and chemical properties, and on the size and
location of the spill or leak, assess the impact on contaminated
environments (e.g. water systems, ground, air equipment, etc.). There
are no methods available to completely eliminate any toxicity this
product may have on aquatic environments. Minimize adverse effects
on these environments. Determine if federal, state, and/or local release
notification is required. Recover as much of the pure product as possible
into appropriate containers. Later, determine if this recovered product can
be used for its intended purpose. Address clean-up of contaminated
environments. Spill or leak residuals may have to be collected and
disposed of. Clay, soil, or commercially available absorbents may be used
to recover any material that can not readily be recovered as pure product.
Flushing residual material to an industrial sewer, if present at the site of a
spill or leak incident, may be acceptable if authorized approval is obtained.
If product and/or spill/leak residuals are flushed to an industrial sewer,
insure that they do not come into contact with incompatible materials. In the
event of a spill, Buckaman Laboratories is available for technical assistance
at 901-767-2722.
WASTE DISPOSAL METHODS: Dispose of in accordance with Federal,
State, and Local laws. This product is not specifically listed in 40 CFT 261
as a Resource Conservation and Recovery Act (RCRA) hazardous waste.
However, spill or leak residuals may meet the criteria for a
characteristic hazardous waste under this Act. Check the
characteristics of the material to be diposed of and/or the physical
and reactivity data given in this MSDS for the neat product.
CONTAINER DISPOSAL: Empty containers, as defined by appropriate
sections of RCRA, are not RCRA hazardous wastes. However, insure
proper management of any residuals remaining in container.

Utility Poles Cited As Chemical Danger
Published: February 5, 1997
WASHINGTON, Feb. 4— An environmental group is advocating the
end of using wooden utility poles because they are usually treated
with dangerous pesticides and wood preservatives.
''Under, around, in and on every preservative-treated utility pole is a
toxic site that poses a real threat to clean air, water and land,'' said a
report issued today by the National Coalition Against the Misuse of
Pesticides.
Instead of using wooden poles, which are protected against decay by
chemicals that are banned for many other uses, the coalition said
utilities should gradually introduce alternatives like steel, concrete
and fiberglass or should bury the lines.
But the Environmental Protection Agency said utility poles and other
approved uses of wood preservatives did not present an
unacceptable risk. ''We did a very extensive risk assessment on wood
preservatives in the mid-80's,'' said an agency spokesman, Al Heier.
''And we finally determined that the benefits outweighed the risks.''
Mr. Heier said wood preservatives, which are also used on decks,
railroad ties and other wood, usually leach out fairly quickly and
should not pose a serious hazard. But there are restrictions on their
uses, like using them inside the home, he said.
Utility poles account for about 13 percent of the market for wood
preservatives used to kill fungus and insects and retard decay, the
report said. The chemicals, which include pentachlorophenol,
creosote, arsenic and chromium, ''contain some of the most
hazardous toxic contaminants on the market,'' the report said.
