EMERGENCY OVERVIEW
Appearance: clear colorless to yellow liquid.
Danger! Causes eye and skin burns. Causes digestive and respiratory tract burns. May be fatal if mist inhaled.
Strong inorganic acid mists containing sulfuric acid may cause cancer. Concentrated sulfuric acid reacts violently with
water and many other substances under certain conditions. May cause lung damage. Hygroscopic (absorbs moisture
from the air). Corrosive to metal.
Target Organs: Lungs, teeth, eyes, skin.
Potential Health Effects
Eye: Causes severe eye burns. May cause irreversible eye injury. May cause blindness. May cause permanent corneal
opacification. The severity of injury depends on the concentration of the solution and the duration of exposure.
Skin: Causes skin burns. The severity of injury depends on the concentration of the solution and the duration of
exposure.
Ingestion: May cause severe and permanent damage to the digestive tract. Causes gastrointestinal tract burns.
Inhalation: May cause irritation of the respiratory tract with burning pain in the nose and throat, coughing,
wheezing, shortness of breath and pulmonary edema. Causes chemical burns to the respiratory tract. Inhalation may
be fatal as a result of spasm, inflammation, edema of the larynx and bronchi, chemical pneumonitis and pulmonary
edema. Because its vapor pressure is negligible, it exists in the air only as a mist or spray. Exposure may impair lung

_o
function and cause mucostasis (reduced mucous clearance).
Chronic: Prolonged or repeated skin contact may cause dermatitis. Prolonged or repeated inhalation may cause
nosebleeds, nasal congestion, erosion of the teeth, perforation of the nasal septum, chest pain and bronchitis.
Prolonged or repeated eye contact may cause conjunctivitis. Effects may be delayed. Workers chronically exposed to
sulfuric acid mists may show various lesions of the skin, tracheobronchitis, stomatitis, conjunctivitis, or gastritis.
Occupational exposure to strong inorganic acid mists containing sulfuric acid is carcinogenic to humans.
Section 4 - First Aid Measures
Eyes: In case of contact, immediately flush eyes with plenty of water for a t least 15 minutes. Get medical aid
immediately.
Skin: In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing
contaminated clothing and shoes. Get medical aid immediately. Wash clothing before reuse.
Ingestion: If swallowed, do NOT induce vomiting. Get medical aid immediately. If victim is fully conscious, give a
cupful of water. Never give anything by mouth to an unconscious person.
Inhalation: POISON material. If inhaled, get medical aid immediately. Remove victim to fresh air. If not breathing,
give artificial respiration. If breathing is difficult, give oxygen.
Notes to Physician: Monitor arterial blood gases, chest x-ray, and pulmonary function tests if respiratory tract
irritation or respiratory depression is evident. Treat dermal irritation or burns with standard topical therapy. Effects
may be delayed. Do NOT use sodium bicarbonate in an attempt to neutralize the acid.
Section 5 - Fire Fiqhting Measures
General Information: As in any fire, wear a self-contained breathing apparatus in pressure -demand, MSHA/NIOSH
(approved or equivalent), and full protective gear. Use water spray to keep fire -exposed containers cool. Substance is
noncombustible. Contact with water can cause violent liberation of heat and splattering of the material. Contact with
metals may evolve flammable hydrogen gas. Runoff from fire control or dilution water may cause pollution. Approach
fire from upwind to avoid hazardous vapors and toxic decomposition products. Strong dehydrating agent, which may
cause ignition of finely divided materials on contact. Oxides of sulfur may be produced in fire.
Extinguishing Media: Use extinguishing media most appropriate for the surrounding fire. Do NOT get water inside
containers. If water is used, care should be taken, since it can generate heat and cause spattering if applied directly
to sulfuric acid.
Flash Point: Not applicable.
Autoignition Temperature: Not available.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating: (estimated) Health: 3; Flammability: 0; Instability: 2; Special Hazard: -W-
Section 6 - Accidental Release Measures
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Carefully scoop up and place into appropriate disposal
container. Provide ventilation. Do not get water inside containers. Cover with dry earth, dry sand, or other non-
combustible material followed with plastic sheet to minimize spreading and contact with water.
Section 7 - Handling and Storage
Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Do not allow
water to get into the container because of violent reaction. Do not get in eyes, on skin, or on clothing. Keep container
tightly closed. Discard contaminated shoes. Use only with adequate ventilation. Do not breathe spray or mist. Do not
littp:Hfscimage.fisliersci.com/msds/22350.htm 3/10/2008

use with metal spatula or other metal items. Inform laundry personnel of contaminant's hazards.
Storage: Do not store near combustible materials. Keep container closed when not in use. Store in a cool, dry, well -
ventilated area away from incompatible substances. Do not store near alkaline substances. Store protected from
moisture. Ideally, sulfuric acid should be stored in isolation from all other chemicals in an approved acid or corrosives
safety cabinet.
Section 8 - Exposure Controls, Personal Protection
Engineering Controls: Facilities storing or utilizing this material should be equipped with an eyewash facility and a
safety shower. Use adequate general or local exhaust ventilation to keep airborne concentrations below the

Carcinogenicity:
CAS# 7664-93-9:
. ACGIH: A2 - Suspected Human Carcinogen (contained in strong inorganic acid mists)
. California: carcinogen, initial date 3/14/03 (listed as Strong inorganic acid mists containing sulfuric acid).
• NTP: Known carcinogen (listed as Strong inorganic acid mists containing s).
. IARC: Group 1 carcinogen
Epidemiology: Workers exposed to industrial sulfuric acid mist showed a statistical increase in laryngeal cancer. This
suggests a possible relationship between carcinogenesis and inhalation of sulfuric acid mist.
Teratogenicity: Sulfuric acid was not teratogenic in mice and rabbits, but was slightly embryotoxic in rabbits (a
minor, rare skeletal variation). The animals were exposed to 5 and 20 mg/m3 for 7 hr/day throughout pregnancy.
Slight maternal toxicity was present at the highest dose in both species.
Reproductive Effects: No information found
Mutagenicity: There are no mutagenicity studies specifically of sulfuric acid. However, there are established effects
of reduced pH in mutagenicity testing, as would be caused by sulfuric acid. These effects are an artifact of low pH and
are not necessarily due to biological effects of sulfuric acid itself.
Neurotoxicity: No information found

Note: Feed System Acceptable Materials
Utilize plastic piping and fittings where possible on neat polymer feed lines. Where strength is needed,
316 SS pumps, valves, etc. can be used. However, these components, especially pump internals, will
have a reduced life span. Be sure to routinely inspect all 316 SS components for signs of corrosion and
to utilize check valves with Teflon or epoxy -coated springs.
DOSAGE AND FEEDING
CORE SHELL 71301 should be fed via a closed feed system. A closed feed system is defined as a
system in which fluid is moved from a closed storage vessel into a treated media without exposure to
the atmosphere (except through normal venting or pressure devices).

Emulsion flocculants must be fed following proper makeup procedures. Suitable inversion systems
should be utilized to allow for adequate inversion and feeding control. The quality of water used to
invert the polymer is important. Avoid using plant recycle water or other water sources high in
suspended solids, mineral salts and iron, and with a pH either below 6.5 or above 7.8. A dilution aging
tank is highly recommended, with a minimum of 30 minutes aging in order to gain full product activity.
Inverting the emulsion flocculent below a concentration of 0.2%, or above a concentration of 0.5%, is
not recommended. A positive displacement pump is recommended for feeding the inverted material to
the treatment system.
In some cases, continuous dilution of pre -inverted flocculent will enhance activity and generate more
cost-effective results. Improved performance using dilution water is site specific. To determine if post -
dilution is advantageous, feed inverted product through a standard mixing tee to an active dilution
water line. The water temperature should be close to ambient and low on suspended solids, mineral
salts and iron.
In most cases, inverted flocculent should be fed on the discharge side of the feed pump. There may be
isolated cases where the additional mixing rendered by distributing the polymer on the suction side of
the pump will yield better program results.

SAFETY AND HANDLING
As with any chemical, CORE SHELL 71301 should be handled with responsible care. Refer to the
Material Safety Data Sheet (MSDS), SECTIONS 3 and 8, for the most current data.
In case of small liquid spills: Contain with absorbent material, such as clay, soil or any commercially
available absorbent. Smaller spills can be effectively cleaned up with NALCO POLYCLEAN 7.

STORAGE
Keep containers closed and protect from frost and moisture. Low temperatures should be avoided
since viscosity increases and pumping problems can occur. When frozen, warm the product slowly to
ambient temperature and agitate with a low (<200) RPM mixer. After warming up to 8 -10°C and re -
homogenization by gentle agitation for about 2 hrs, the product can be re -used without loss in
efficiency. Nevertheless freezing should be avoided.
When the product has been exposed to heat, the product should be gently agitated while its
temperature is allowed to lower to room temperature. After the product is back to room temperature,
about 2 hrs of gentle agitation should be sufficient to make the product ready for use. While product
performance should not be affected if the product freezes or warms up, some loss in physical stability
should be expected. If the product is to be stored for longer than two weeks, i.e., bulk tank storage,
periodic agitation of the product will help keep the product fully homogenized and ensure consistent
performance. Refer to the Material Safety Data Sheet (MSDS), SECTION 7, for the most current data.
