Potential Health Effects
----------------------------------
Inhalation:
Tri Sodium Phosphate 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:
Tri Sodium Phosphate 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:
Tri Sodium Phosphate 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:
Tri Sodium Phosphate 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 Section 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 and engineering controls are not feasible, a
full facepiece respirator with high efficiency particulate filter (NIOSH type
N100 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. If oil particles (e.g. lubricants, cutting
fluids, glycerin, etc.) are present, use a NIOSH type Ror P filter. 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.
