Potential Health Effects
----------------------------------
REAGENTS, INC.--MSDS--SODIUM PHOSPHATE DIBASIC, ANHYDROUS PAGE 2
Inhalation: May cause irritation to the respiratory tract. Symptoms may include coughing and shortness of
breath.
Ingestion: Phosphates are slowly and incompletely absorbed when ingested, and seldom result in systemic
effects. Such effects, however, have occurred. Symptoms may include vomiting, lethargy, diarrhea, blood
chemistry effects, heart disturbances and central nervous system effects. The toxicity of phosphates is because
of their ability to sequester calcium.
Skin Contact: May cause irritation with redness and pain.
Eye Contact: May cause irritation, redness and pain.
Chronic Exposure: May sequester calcium and cause calcium phosphate deposits in the kidneys. Chronic
ingestion or inhalation may induce systemic phosphorous poisoning. Liver damage, kidney damage, jaw/tooth
abnormalities, blood disorders and cardiovascular effects can result.
Aggravation of Pre-existing Conditions: Persons with pre-existing skin disorders or eye problems, jaw/tooth
abnormalities, or impaired liver, kidney or respiratory function may be more susceptible to the effects of the
substance.
4. First Aid Measures
Inhalation: Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion: Give large amounts of water to drink. Never give anything by mouth to an unconscious person. Get
medical attention.
Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated
clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention if
irritation develops.
Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower eyelids
occasionally. Get medical attention if irritation persists.
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. Small amounts of residue may be flushed to sewer with plenty of water. 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.
Isolate from incompatible substances. 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: None established.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as
low as possible. 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): For conditions of use where exposure to dust or mist is apparent
and engineering controls are not feasible, a particulate respirator (NIOSH type N95 or better filters) may be
worn. If oil particles (e.g. lubricants, cutting fluids, glycerin, etc.) are present, use a NIOSH type R or P filter.
For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-
supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient
atmospheres.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work
area.
