  3. Hazards Identification
    EMERGENCY OVERVIEW
    ------------------------------
    WARNING! Harmful if swallowed or inhaled. Causes irritation to skin, eyes and respiratory tract.
    ------------------------------

    Potential Health Effects

    Health Rating: 2 - moderate
    Flammability Rating: 0 - none
    Reactivity Rating: 1 - slight
    Contact Rating: 2 - moderate
    Lab Protective Equip: goggles; lab coat; vent hood; proper gloves
    Storage Color Code: Orange (general storage)

    Inhalation: Causes irritation to the respiratory tract. Symptoms may include coughing, shortness of breath. Behaves as a moderately strong alkali; intense exposure may result in the destruction of mucous membranes. May cause asthmatic bronchitis, chemical pneumonitis, or pulmonary edema.

    Ingestion: Causes irritation to the gastrointestinal tract. Symptoms may include nausea, vomiting and diarrhea. May cause mild burning of mouth, throat, and stomach. Its alkaline nature may injure the esophagus and digestive tract. Aqueous, highly alkaline solutions may produce caustic burns.

    Skin Contact: Causes irritation to skin. Symptoms include redness, itching, and pain. Extent of damage depends on duration of contact. More serious effects may occur if the skin is moist. Aqueous, highly alkaline solutions may produce caustic burns.

    Eye Contact: Causes irritation to eyes, may be severe with possible corneal damage. Aqueous, highly alkaline solutions may produce caustic burns.

    Chronic Exposure: Repeated exposure may cause symptoms similar to those listed for acute effects. May cause permanent tissue damage to the skin and eyes. Aggravation of pre-existing conditions: No information found.
  4. First Aid Measures
    Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.

    Ingestion: Do not induce vomiting. Give large amounts of water. Never give anything by mouth to an unconscious person. Get medical attention.

    Skin Contact: Immediately flush skin with plenty of soap and water for at least 15 minutes. Remove contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse.

    Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.
  5. Fire Fighting Measures
    Fire: Not considered to be a fire hazard. Explosion: Not considered to be an explosion hazard.

    Fire Extinguishing Media: Use any means suitable for extinguishing surrounding fire.

    Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.
  6. Accidental Release Measures
    Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in 8. Spills: Sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust dispersal. Us regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of reportable quantities. The toll free number for the us coast guard national response center is (800) 424-8802.
  7. Handling and Storage
    Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
  8. Exposure Controls/Personal Protection
    Airborne Exposure Limits: TriSodium Phosphate: -aiha workplace

    Environmental exposure limit: 5 mg/m3 (15-minute stel)

    Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures below the airborne exposure limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, industrial ventilation, a manual of recommended practices, most recent edition, for details.

    Personal respirators (NIOSH approved): If the exposure limit is exceeded, a full facepiece respirator with high efficiency dust/mist filter may be worn up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator.

    Warning: Air purifying respirators do not protect workers in oxygen-deficient atmospheres.

    Skin Protection: Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.

    Eye Protection:
    Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
