R100ESWILE REOt.0#;AL OFFICE
In July of 1996 we received a request from Shurtape Technologies, Inc. to review and evaluate
several chemicals for proposed boiler and cooling tower use. Since this time we have spoken by telephone
with the facility to request additional documentation and clarification of numerous issues. Our most recent
conversation was 11/4/96 when I spoke with Mr. Bill Little. To this date, we have not received the
requested information and are returning the request to your office with the following recommendations:
1) Biosperse 261T microbiocide - facility needs to supply half-life documentation
2) Biosperse 250 microbiocide - facility needs to complete Metals Worksheet
3) Advantage Plus 1423 deposit/corrosion inhibitor - does not appear to be used as a biocide and active
ingredients are not commonly considered biocidal in nature (recommend that product be approved for use)
4) Advantage Plus 6445 deposit inhibitor - appears to be non-biocidal but we need clarification of the 0-
4% active ingredient listed as "trade secret" on the MSDS
5) Valugard 250 D cooling water treatment - cannot evaluate product in that three of the five active
ingredients (1-10%) are listed as "trade secret" on the MSDS
6) Drewsperse 751 antifoulant - product appears to contain a biocidal active ingredient (10-25% quaternary
ammonium compound polyethoxylate) but we need a more specific description and a Biocide 101
Worksheet would need to be completed
I have also spoken with Mr. Little regarding the "trade secret" issue. I suggested that the chemical
supplier could submit the information to our office directly with the appropriate pages marked
"proprietary." This has worked well in the past with suppliers that were uncomfortable with this type of
information being accessible. If there are questions concerning this review please contact me at (919)733-
2136.

Potential Health Effects
Eye
Exposure causes irreversible eye damage. Symptoms may include stinging,
tearing, redness, swelling, corneal damage, and blindness. Additional symptoms
of eye exposure may include: blurred vision halo vision (characterized by
blurring vision around bright objects)
Skin
Exposure causes severe skin irritation. Symptoms may include redness, burning,
and severe skin damage. Skin absorption is possible, and may contribute to
symptoms of toxicity from other routes of exposure.
Swallowing
Single dose oral toxicity is low. Swallowing small amounts during normal
handling is not likely to cause harmful effects; swallowing large amounts may
be harmful.
Inhalation
Exposure to vapor or mist is possible.
Symptoms of Exposure
gastrointestinal irritation (nausea, vomiting, diarrhea), irritation (nose,
throat, respiratory tract), headache, muscle weakness.
Target Organ Effects
Overexposure to this material (or its components) has been suggested as a cause
of the following effects in laboratory animals, and may aggravate pre-existing
disorders of these organs in humans: liver abnormalities, eye damage, kidney
damage.

3. HAZARDS IDENTIFICATION
Potential Health Effects
Eye
Exposure causes severe eye irritation. Symptoms may include stinging, tearing,
redness, swelling, and eye damage.
Skin
Exposure causes severe skin irritation. Symptoms may include redness, burning,
and severe skin damage. Additional symptoms of skin contact may include:
allergic skin reaction Skin absorption is possible, and may contribute to
Symptoms of toxicity from other routes of exposure.
Swallowing
Exposure may be harmful or fatal. Symptoms may include severe stomach and
intestinal irritation (nausea, vomiting, diarrhea), abdominal pain, and
vomiting of blood. Swallowing this material may cause burns and destroy tissue
in the mouth, throat, and digestive tract. Low blood pressure and shock may
occur as a result of severe tissue injury.
Inhalation
Exposure to vapor or mist is possible.
Symptoms of Exposure

4. FIRST AID MEASURES _._
Eyes
If material gets into the eyes, immediately flush eyes gently with water for at
_least 15 minutes while holding eyelids apart. If.symptoms develop as a.result
of vapor exposure, immediately move individual away from exposure and into
fresh air before flushing as recommended above. Seek immediate medical
attention.
Skin
Immediately flush skin with water for at least 15 minutes while removing
contaminated clothing and shoes. Seek immediate medical attention. Wash
- clothing before reuse and decontaminate or discard•contaminated shoes.
Swallowing
Seek immediate medical attention. Do not induce vomiting. Vomiting will cause

immediately rinse mouth with water and give milk or'water to drink. If
possible, do not leave individual unattended.
Inhalation
If symptoms develop, immediately move individual away from exposure and into
fresh air. Seek immediate medical attention; keep person warm and quiet. If
person is not breathing, begin artificial respiration. If breathing is
difficult, administer oxygen.

decontaminated area is washed with additional decontaminant solution and then
flushed into a chemical or municipal sewer. Do not discharge spills and

is much less effective when alkaline. In converting sodium sulfite to the
bisulfite, dissolve the salt in water and slowly add the acid with good
agitation to prevent liberation of sulfur dioxide caused by local excess of
acid. Keep containers of decontaminant solution closed or covered to reduce
accumulation of sulfur dioxide in the workplace(threshold limit value(ACGIH) 2
ppm). The solutions should be made fresh as needed. Personnel making up or
handling decontaminant solutions should wear goggles or face shield and rubber
gloves.

7. HANDLING AND STORAGE
Handling
Containers of this material may be hazardous when emptied. Since emptied
containers retain product residues (vapor, liquid, and/or solid), all hazard
precautions given in the data sheet must be observed.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Eye Protection
Chemical splash goggles and face shield (8" min.) in compliance with OSHA
regulations are advised; however, OSHA regulations also permit other type
safety glasses. (Consult your industrial hygienist.)
Skin Protection
Wear resistant gloves such as:, -neoprene, nitrile rubber, To prevent skin
contact, wear impervious clothing and boots., Other protective equipment:
eyewash station, emergency shower..
Respiratory Protections
If overexposure has been determined or documented, a NIOSH/MSHA jointly
approved air supplied.respirator is advised in absence of proper environmental
control. OSHA regulations also permit other NIOSH/MSHA res irators under
specified conditions. (See your safety equipment supplier. Engineering or
administrative controls should be implemented to reduce exposure.
Engineering Controls
Provide sufficient mechanical (general and/or local exhaust) ventilation to
maintain exposure below level of overexposure (from known, suspected or
apparent adverse effects).

j General Degradation Data
SIOSPERSE 250 microbiocide is a broad-spectrum
antimicrobial product designed specifically for control
of bacteria, fungi and algae in industrial recirculating
cooling water systems such as cooling towers, -
pasteurizers, air washers and evaporative condens-
ers as well as for use as a preservative in aqueous
metal working fluids. This Environmental Profile is
designed to address common questions about the
impact of BIOSPERSE 250 tnicrobiocide on the
environment.
The degradation scheme for the active components
of BIOSPERSE 250 is isothiazolinone to N-methyl-
malonamic-acid to malonamic acid to malonic acid
with the final products being acetic acid, formic acid
and carbon dioxide.
