If copper, zinc, or chromium are present in the proposed biocidal compound, complete this worksheet. A separate form
must be used for each metal and/or metal compound present in the biocide. List the metal, its chemical formula, molecular
weight (MW), formula weight (FW), and the concentration of the metal compound in the biocide (MCC). Complete a
separate form for every metal present in the biocide.
Metal Chemical Formula Molecular Weight of Metal Formula Weight Concentration in Biocide
EXAMPLE
Copper CuSO4.5H2O 63.546 g/mole 249.680 g/mole 0.2 %
None
Dosage rate of Biocide (DR) (from page 1):
DR = grams/day
Average Daily Discharge (ADD) (from page 1):
ADD = million gallons/day
Discharge Concentration (DC) of Biocide:
DC - DR _ ( grams/day) _ grams/million gallons
- ADD - ( million gallons/day) -
Convert DC to micrograms/liter(ppb):
DC (pg/I) = DC (grams/million gal) x 1 x 106 pg/g = pg/I
3.785 x 106 liters/million gal.
Calculate the fraction of metal in the metal-containing compound (MF):
MF - MW ( grams/mole) _

If copper, zinc, or chromium are present in the proposed biocidal compound, complete this worksheet. A separate form
must be used for each metal and/or metal compound present in the biocide. List the metal, its chemical formula, molecular
weight (MW), formula weight (FW), and the concentration of the metal compound in the biocide (MCC). Complete a
separate form for every metal present in the biocide.
Metal Chemical Formula Molecular Weight of Metal Formula Weight Concentration in Biocide
EXAMPLE
Copper CuSO4.5H2O 63.546 g/mole 249.680 g/mole 0.2%
Dosage rate of Biocide (DR) (from page 1):
DR = grams/day
Average Daily Discharge (ADD) (from page 1):
ADD = million gallons/day
Discharge Concentration (DC) of Biocide:
DR ( grams/day)
DC = ADD = ( million gallons/day) = grams/million gallons
Convert DC to micrograms/liter(ppb):
1 x 106 pg/g
DC (pg/I) = DC (grams/million gal) x = pg/I
3.785 x 106 liters/million gal.
Calculate the fraction of metal in the metal-containing compound (MF):
MF - MW - ( grams/mole) -
FW - ( _ grams/mole) -
Calculate the fraction of metal in the biocidal compound (BF):
MCC (%)
BF = MF x 100 = x (100) -
Calculate the concentration of metal in the discharge(M):
M = DC x BF = pg/I x = pg/I
Calculate the instream metal concentration (IMC) at low-flow conditions:
IMC = M x I 1000%) = pg/I x 100 % = leg/1

5 FIRE FIGHTING MEASURES (CONT)
EXTINGUISHING MEDIA:
Small fire: Use carbon dioxide or dry chemical to extinguish fire.
Large fire: Flood fire area with large quantities of water, while knocking down vapors with fog. If insufficient
water supply, knock down vapors only
Tank fire: Cool containers with flooding quantities of water until well after fire is out. Do not get water
inside containers. Evacuate immediately if sound from safety vents or discoloration of tank. Stay
clear of tanks engulfed in fire.
PROTECTIVE EQUIPMENT:
Evacuate personnel to a safe area. Keep personnel removed and upwind of fire. Generates heat
upon addition of water, with possibility of spattering. Wear full protective clothing. Runoff from
fire control may cause pollution. Neutralize run-off with sodium bicarbonate or soda ash to
prevent corrosion of metals and formation of hydrogen gas. Wear self-contained breathing
apparatus if fumes or mists are present.
6 ACCIDENTAL RELEASE MEASURES
EMERGENCY PROCEDURES: Review Fire and Explosion Hazards [Section #5] . Take immediate
steps to stop and contain release if possible.
CLEAN-UP METHODS: Soak up small spills with dry sand or diatomaceous earth. Contain large
spills and cautiously dilute and neutralize with lime or soda ash. Caution
should be exercised regarding personnel safety and exposure to the
released product.
Notify local authorities and the National Response Center, if required. If
the product is spilled and not recovered, or is recovered as a waste for
treatment or disposal, the Reportable Quantity (US DOT) is 1,000 lbs
(based on the sulfuric acid content of the solution spilled).
PROTECTIVE EQUIPMENT: See "Exposure Controls/Personal Protection" [Section#8].
7 HANDLING AND STORAGE
HANDLING:
DO NOT get in eyes, on skin, or on clothing. Avoid breathing vapors or mist. Wear approved respirators if
adequate ventilation can not be provided. Wash thoroughly after handling. Do not eat, drink or smoke in areas of
use or storage. NEVER add water to acid.
STORAGE:
Avoid contact with combustible materials, water, metals and alkalis. Store in a vented container. This material
should be stored and shipped in containers specially designed for sulfuric acid. DO NOT add water or other
