infection. Effects may be delayed. Aspiration into the lungs may cause chemical

pneumonia and lung damage.

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 “ strong inorganic acid mists containing sulfuric acid” 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 “strong inorganic acid mists containing sulfuric acid” 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

“sulfuric acid contained in strong inorganic acid mists” as an A2- Suspected Human

Carcinogen.

  1.  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.

  1.  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.

  1.   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.
