Potential Environmental Effects: See Section 12.
- COMPOSITION/INFORMATION ON INGREDIENTS
Component CAS Number % by Wt.
Phosphoric Acid 7664-38-2 35 – 75 %
Sulfuric Acid 7664-93-9 10 – 50 %
- 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. Remove contact lens if easy to
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 and shoes until cleaned. Do not
apply oils or ointments unless ordered by the 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:
This product contains materials that may cause severe pneumonitis if aspirated. If ingestion has occurred less
than 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 artifical 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 MEASURES
Extinguishing Media: Not flammable or combustible. For fires in area use appropriate media. For example:
Water spray. Dry chemical. Carbon dioxide. Foam.
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. Product generates heat upon addition
of water, with possible spattering. Run-off from fire control may cause pollution. Do not get water inside
containers. Neutralize run-off with Lime, Soda Ash, etc., to prevent corrosion of metals and formation of
Hydrogen gas.
Fire and Explosion Hazards: Product may react with some metals (ex.: Aluminum, Zinc, Tin, etc.) to release
flammable hydrogen gas. Will react with organic materials with evolution of heat and sulfur dioxide. Concentrated
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. Phosphine. Toxic vapors. Sulfur oxides.
- ACCIDENTAL RELEASE MEASURES
Spill Clean-Up Procedures: CORROSIVE 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. Soak up residue with inert
absorbent material. Place in non-leaking containers for immediate disposal. Flush remaining area with water and

neutralize with Soda Ash, Lime or Limestone and dispose of properly. Adequate ventilation is required if soda
ash is used, because of the consequent release of carbon dioxide gas. Avoid direct discharge to sewers and
surface waters. Notify authorities if entry occurs.
- HANDLING AND STORAGE
Handling: Avoid contact with eyes, skin, and clothing. Use with adequate ventilation. Do not swallow. Avoid
breathing vapors, mists, or dust. Do not eat, drink, or smoke in work area. Wash thoroughly after handling.
Empty containers retain product residue (vapor, dust, or liquid) and can be dangerous. DO NOT pressurize, cut,
weld, braze, solder, drill, grind, or expose such containers to heat, flame, sparks, static electricity, or other
source of ignition. They may explode and cause injury or death. CORROSIVE MATERIAL. Ground lines and
equipment used during transfer to reduce the possibility of static spark-initiated fire or explosion. Use non-
sparking tools.
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 metal containers. Elevated
temperatures will increase the corrosion rate of most metals.

Engineering Controls: Local exhaust ventilation, process enclosures, or other engineering controls are required
when handling or using this product to avoid overexposure. Maintain adequate ventilation. Do not use in closed
or confined spaces. Avoid creating dust or mist. Keep levels below exposure limits. To determine exposure
levels, monitoring should be performed regularly.
Eye/Face Protection: Wear chemical safety goggles and a full face shield while handling this product. Do not
wear contact lenses.
Skin Protection: Prevent contact with this product. Wear gloves and protective clothing depending on condition
of use. Protective gloves: Acid-proof. Gauntlet-type. Neoprene. Butyl rubber.
Respiratory Protection: Respiratory protection must be worn if ventilation does not eliminate symptoms or keep
levels below recommended exposure limits. If exposure limits are exceeded, wear: NIOSH-Approved air-
purifying respirator with: Acid gas cartridge and Dust/mist filter. NIOSH-Approved positive pressure supplied air
respirator. NIOSH-Approved self-contained breathing apparatus. DO NOT exceed limits established by the
respirator manufacturer. All respiratory protection programs must comply with OSHA 29 CFR 1910.134 and
ANSI Z88.2 requirements and must be followed whenever workplace conditions require a respirator’s use.
Other Protective Equipment: Eye-wash station. Safety shower. Rubber apron. Chemical safety shoes. Rubber
boots. Protective clothing. Full-rubber acid suit.
General Hygiene Conditions: Wash with soap and water before meal times and at the end of each work shift.

Possibility of Hazardous Reactions: Hazardous polymerization will not occur under normal conditions. May
react with certain metals to produce flammable hydrogen gas. Mixing with strong bases can cause high heat of
reaction and generate steam. Reacts with chlorides + stainless steel to form explosive hydrogen gas. Phosphoric
acid forms flammable gases with sulfides, mercaptans, cyanides and aldehydes. Phosphoric acid mixtures with
nitromethane are explosive. Hazardous gases are evolved on contact with chemicals such as cyanides, sulfides,
carbides, etc.
