MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE TO PRODUCT:
Skin disorders. Respiratory system disorders. Eye disorders.
OTHER:
Circulatory collapse with clammy skin, weak and rapid pulse, shallow respirations, and
scanty urine may follow skin contact or ingestion. Circulatory shock is often the
immediate cause of death.
CANCER INFORMATION:
This product does not contain greater than 0.1% of the known or potential carcinogens
listed in NTP, IARC or OSHA. The International Agency for Research on Cancer
(IARC) has classified 鈥? strong inorganic acid mists containing sulfuric acid鈥? as a known
human carcinogen (IARC Category 1). This classification is for inorganic acid mists only
and does not apply to sulfuric acid solutions. The National Toxicology Program (NTP)
lists 鈥渟trong inorganic acid mists containing sulfuric acid鈥? as a known human carcinogen.
This limits the classification to sulfuric acid aerosols and does not extend to the liquid
product, unless the acid is used under conditions that result in the formation of mists or
aerosols. The American Conference of Governmental Industry Hygienists (ACGIH) lists
鈥渟ulfuric acid contained in strong inorganic acid mists鈥? as an A2- Suspected Human
Carcinogen.
4. First Aid Measures
EYE CONTACT:
Immediately flush eyes with plenty of water for at least 15 minutes while holding eyelids
open. Tilt head to avoid contaminating unaffected eye. Get immediate medical attention.
SKIN CONTACT:
Immediately flush skin with plenty of water for at least 15 minutes while removing
contaminated clothing and shoes. Get medical attention immediately.
Do not reuse clothing until cleaned.
Do not apply oils or ointments unless ordered by a physician. Discard contaminated
leather articles such as shoes and belt.

INHALATION: Remove to fresh air. If breathing is difficult, administer oxygen. If not
breathing, give artificial respiration, preferably mouth-to-mouth. GET MEDICAL
ATTENTION IMMEDIATELY.
INGESTION:
If fully conscious, drink a quart of water. DO NOT induce vomiting. CALL A
PHYSICIAN IMMEDIATELY. If unconscious or in convulsions, take immediately to a
hospital or a physician. NEVER induce vomiting or give anything by mouth to an
unconscious victim. If vomiting occurs spontaneously, keep head below hips to prevent
aspiration of liquid into the lungs.
NOTE TO PHYSICIANS: The use of gastric lavage is controversial. The advantage of
removal of acid must be weighted against the risk of perforation or bleeding. If a large
amount of acid (>1 ml/kg body weight) has been recently ingested, cautious gastric
lavage is generally advised if the patient is alert and there is little risk of convulsions.
Consultation with a gastroenterologist and/or surgeon is advised. Serious complications
such as perforation or stricture of the esophagus may occur requiring care by specialists.
Laryngeal edema may develop requiring intubation or tracheostomy. This product
contains materials that may cause sever pneumonitis if aspirated. If ingestion has
occurred less that 2 hours earlier, carry out careful gastric lavage; use endotracheal cuff if
available, to prevent aspiration. Observe patient for respiratory difficulty from aspiration
pneumonitis. Give artificial resuscitation and appropriate chemotherapy if respiration is
depressed. Following exposure the patient should be kept under medical review for at
least 48 hours as delayed pneumonitis may occur. DO NOT attempt to neutralize the acid
with weak bases since the reaction will produce heat that may extend the corrosive injury.

FIRE FIGHTING METHODS:
Evacuate area of unprotected personnel. Wear protective clothing including NIOSH-
approved self-contained breathing apparatus. Remain upwind of fire to avoid hazardous
vapors and decomposition products. Use water spray to cool fire-exposed containers.
Do not get water inside containers. Product generates heat upon addition of water, with
possible spattering. Neutralize run-off with Lime, Soda Ash, etc., to prevent corrosion of
metals and formation of Hydrogen gas. Run-off from fire control may cause pollution.
FIRE AND EXPLOSION HAZARDS:
Product may react with some metals (ex. Aluminum, Zinc, Tin, etc.) to release flammable
hydrogen gas.
This product may react with certain metals to produce flammable Hydrogen Gas. Will
react with organic materials with evolution of heat and sulfur dioxide. Concentrated
sulfuric acid is a strong oxidizing agent. May cause ignition of combustible materials on
contact with generation of sulfur dioxide fumes.
HAZARDOUS COMBUSTION PRODUCTS:
Phosphorous oxides. Sulfur oxides.
6. Accidental Release Measures
SPILL CLEAN-UP PROCEDURES:
CORRSIVE MATERIAL: Evacuate unprotected personnel from area. Maintain adequate
ventilation. Follow personal protective equipment recommendations found in Section 8.
Never exceed any occupational exposure limit. Contain spill, place into drums for proper
disposal. Flush remaining area with water and neutralize with Soda Ash and dispose of
properly. Exercise caution during neutralization as considerable heat may be generated.
Avoid direct discharge to sewers and surface waters. Notify authorities if entry occurs.
7. Handling And Storage
STORAGE:
CORROSIVE MATERIAL: Store in a cool, well-ventilated area, out of direct sunlight.
Store in a dry location away from heat. Keep away from incompatible materials. Keep
containers tightly closed. Do not store in unlabeled or mislabeled containers.
Do not freeze. Highly corrosive to most metals with evolution of hydrogen gas.
Explosive/flammable concentrations of hydrogen gas may accumulate inside

For detailed toxicological information on individual chemical components contained in
this product, contact the address in Section 1 of this MSDS.
The International Agency for Research on Cancer ( IARC) has concluded that
occupational exposure to strong inorganic acid mists containing sulfuric acid is
carcinogenic to man, causing cancer of the larynx (the voice box) and, to a lesser extent,
the lung. Although no direct link has been established between exposure to sulfuric acid
itself, and cancer in man, exposure to any mist or aerosol during use of this product
should be avoided and, in any case, keep exposures below the occupational exposure
limit for sulfuric acid.
