August
12, 2005 - Report of toxic
spill at Phillips plant not needed. By Nik Bonopartis. Poukeepsie
Journal (NY).
... Gerald
Sliss is a former IBM senior engineering specialist at the East
Fishkill site. The plant has had similar problems with releases
of chemicals and with maintenance of the exhaust systems dating
back to when it was owned by IBM. The exhaust systems, he said,
did not have "scrubbers" to clean air ducts until
employees began filing complaints with OSHA.
"The
exhaust systems were corroding and guys were getting stuff literally
dripping down on them," said Sliss, who was laid off by
IBM in 1993 after 24 years. Sliss has done some work at the
site after 1993 while working for third-party vendors who supplied
materials for the manufacturing process
Sliss said despite advances in technology, manufacturing companies
haven't found efficient and safe ways to handle and remove chemical
byproducts.
"This
is an industry-wide problem," he said. "The problem
is the whole process is dirty and always has been." |
August
4, 2005 - Powdery
chemical covers cars in East Fishkill. Philips plant emitted
substance. By Nik Bonopartis. Poughkeepsie Journal (NY).
... The "spill" happened on July 7 at the East Fishkill
IBM and Philips Semiconductor campus, according to internal
documents from IBM and Philips. About 80 cars belonging to employees
of Philips and IBM were coated with the chemical compound...
The chemical was re-leased during a maintenance project on exhaust
ducts in the Philips manufacturing plant, Philips spokesman
Paul Morrison said... There is some confusion
about how much ammonium fluorosilicate constitutes "reportable
levels." Morrison did not say exactly how much was released,
and the DEC could not say how much of the chemical would need
to be released before it was considered an environmental hazard.

US
EPA List of Inerts. This
substance is on List
3.
Note:
US EPA allows so-called "Inert" ingredients to be commonly
mixed with the "active" pesticidal ingredient to
create a formulated pesticide product. According
to EPA, "The term `inert' is not intended to imply
nontoxicity; the ingredient may or may not be chemically active."
"Inert" ingredients include solvents, emulsifiers,
spreaders, and other substances mixed into pesticide products
to increase the effectiveness of the active ingredients, make
the product easier to apply, or to allow several active ingredients
to mix in one solution. Both US EPA and California Department
of Pesticide Regulation require pesticide manufacturers to
identify inert ingredients in their products but do not disclose
this information to the general public because the pesticide
industry considers product formulations trade secrets, protected
by law and by the US EPA. The US EPA category of Inerts (as
of September 2003):
List 1 - Of Toxicological
Concern
List 2 - Potentially
Toxic / High Priority for Testing
List
3 - Of Unknown Toxicity
List 4A - Generally Regarded as Safe
List 4B - EPA states it has Sufficient Information to Reasonably
Conclude that the Current Use Pattern in Pesticide Products
will not Adversely Affect Public Health or the Environment

MANUAL
FOR THE IDENTIFICATION OF HOUSE FUNGI

Abstract:
HAPAB One chapter of this manual treats the prevention and
control of woodrotting fungi. The toxicity
of the usual water-soluble preservatives, sodium fluoride,
is similar to that of silicofluoride and ammonium silicofluoride,
and so all three require the same safety measures. The preservative
oil, EAG-2 (concentrated emulsion of generator schist tar
dissolved in caustic soda, with gas oil and sodium phosphate),
is highly toxic to wood-rotting fungi, and its insecticidal
activity is increased by adding hexachloran. It does, however,
have a strong odor of schist tar which persists for 3-3 weeks
and is most unpleasant for the workmen applying the preservative.
Safety regulations for work with wood preservatives are listed:
provision of sand, and fire equipment; use of overalls, gloves,
protective footwear, goggles and respirators by operators;
coating of hands and faces with protective creams; provision
of water and first- aid equipment; and use of special instructions
in the handling of preservatives. SAFETY 67/04/00, 47 1956

Explanation
from PAN: |
*
Parent: Compounds labeled with a "P" are the parent
compound of the group. The parent chemical was chosen on the
basis of available toxicity information, where chemicals with
the maximum amount of toxicity information assigned to parent
status. Where no toxicity information was available for any
member of a group, we assigned parent status to the least
derivatized member of the group for organic compounds (e.g.,
benzoic acid would be the parent instead of methyl benzoate),
the sodium salt (for compounds with a common anion), or the
chloride salt (for compounds with a common cation). These
are general guidelines and not hard and fast rules, because
the groups are rarely so easy to categorize. For some groups
with no obvious parent, assignment of parent status was arbitrary. |
Group
1: Salts, esters and/or complexes of the parent chemical,
e.g., glyphosate and glyphosate, isopropylamine salt; 2,4-D
and 2,4-D, butoxyethyl ester. Alternatively, the parent
compound itself is an ester or salt, and related compounds
are other esters or salts.
