    Section 3 - Hazards Identification

    EMERGENCY OVERVIEW
    Danger! Causes digestive and respiratory tract burns. Causes eye and skin burns. Hygroscopic (absorbs moisture from the air). Corrosive to metal.
    Target Organs: Eyes, skin, mucous membranes.

    Potential Health Effects

    Eye: May cause irreversible eye injury. Contact with liquid is corrosive to the eyes and causes severe burns.
    Skin: Contact with liquid is corrosive and causes severe burns and ulceration. The severity of injury depends on the concentration of the solution and the duration of exposure.
    Ingestion: Causes gastrointestinal tract burns. May cause corrosion and permanent tissue destruction of the esophagus and digestive tract.
    Inhalation: Causes chemical burns to the respiratory tract. Because its vapor pressure is negligible, it exists in the air only as a mist or spray.
    Chronic: Prolonged or repeated skin contact may cause dermatitis.

    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: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
    Notes to Physician: Persons with pre-existing skin disorders or impaired respiratory or pulmonary function may be at increased risk to the effects of this substance. Treat symptomatically and supportively.

    Section 5 - Fire Fighting 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. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Substance is noncombustible. Contact with metals may evolve flammable hydrogen gas.
    Extinguishing Media: Use extinguishing media most appropriate for the surrounding fire.
    Flash Point: Not applicable.
    Autoignition Temperature: Not applicable.
    Explosion Limits, Lower:Not available.
    Upper: Not available.
    NFPA Rating: (estimated) Health: 3; Flammability: 0; Instability: 0

    Section 6 - Accidental Release Measures

    General Information: Use proper personal protective equipment as indicated in Section 8.
    Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, observing precautions in the Protective Equipment section. Provide ventilation. Spill may be carefully neutralized with lime (calcium oxide, CaO).

    Section 7 - Handling and Storage

    Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Do not ingest or inhale. Use with adequate ventilation. Discard contaminated shoes.
    Storage: Keep container closed when not in use. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from metals. Do not store in metal containers. Store protected from moisture. Store away from alkalies.

    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 permissible exposure limits.
    OSHA Vacated PELs: Phosphoric acid: 1 mg/m3 TWA Water: No OSHA Vacated PELs are listed for this chemical.
    Personal Protective Equipment
    Eyes: Wear chemical goggles and face shield.
    Skin: Wear appropriate protective gloves to prevent skin exposure.
    Clothing: Wear appropriate protective clothing to prevent skin exposure.
    Respirators: A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.

    Environmental: The acidity of phosphoric acid may be reduced readily by natural water hardness minerals, but the phosphate may persist indefinitely. During transport through the soil, phosphoric acid will dissolve some of the soil material, in particular, carbonate-based materials. The acid will be neutralized to some degree with adsorption of the proton and phosphate ions also possible. However, significant amounts of acid will remain for transport down toward the groundwater table.
    Physical: No information available.
    Other: Dangerous to aquatic life in high concentrations.
