<br /> Carcinogenicity:Neither the NTP,IARC,nor OSHA lists trisodium phosphate as a carcinogen.
<br /> Summary of Risks:Inhaling this alkaline material's dust or mist irritates the respiratory tract.Aqueous,highly alkaline solutions may also
<br /> produce caustic burns.
<br /> Medical Conditions Aggravated by Long-Term Exposure:Permanent tissue damage to the skin and eyes.
<br /> Target Organs:Skin,digestive tract.
<br /> Primary Entry:Inhalation and ingestion.Its alkaline nature irritates and may injure the digestive tract.To use as a food additive requires
<br /> reducing its alkalinity.
<br /> Acute Effects:Tissue irritation upon contact with skin and eyes.
<br /> Chronic Effects: Prolonged or repeated eye and skin contact causes irritation.Injury to the esophagus from scarring may occur.Alkali exposures
<br /> may necessitate irrigation for extended duration.
<br /> FIRST AID
<br /> Eyes:Flush immediately,including under the eyelids,gently but thoroughly with flooding amounts of running water for at least 15 min.
<br /> Skin:After rinsing affected area with flooding amounts of water,wash it with soap and water.
<br /> Inhalation:Remove exposed person to fresh air and support breathing as needed.
<br /> Ingestion:Never give anything by mouth to an unconscious or convulsing person.If ingested,have that conscious person drink 1 to 2 glasses of
<br /> water or milk to dilute;then give fruit juice or diluted vinegar to drink.Never induce vomiting unless instructed by a physician to do so.
<br /> After first aid,get appropriate in-plant,paramedic,or community medical attention and support.
<br /> Spill/Leak:Cleanup personnel should wear the necessary personal protective equipment to prevent skin or eye contact and dust inhalation.For
<br /> liquid(solution)spills,cover the material with an inert solid absorbent(vermiculite or dry sand)and scoop into an appropriate container(with
<br /> secure lid)for disposal in accordance with existing regulations.Dike with inert absorbent material,as needed,to contain and limit spill area.
<br /> Sweep,vacuum,or scoop the spilled solid,avoiding dust generation,into a suitable disposal container(with secure lid).Flush residues to drain
<br /> with plenty of water.
<br /> Disposal:Scrap material can be used for neutralizing acid wastes or buried in an approved landfill.If regulations permit,you may flush small
<br /> amounts to drain with large excess of water.Contact your supplier or a licensed contractor for detailed recommendations.Follow applicable
<br /> Federal,state,and local regulations.
<br /> OSHA Designations
<br /> Air Contaminant(29 CFR 1910.1000,Subpart Z):Not listed
<br /> EPA Designations
<br /> RCRA Hazardous Waste(40 CFR 261.33):Not listed
<br /> Listed as CERCLA Hazardous Substance*(40 CFR 302.4),Reportable Quantity(RQ):5000 lb(2270 kg)[+per Clean Water Act,Sec.311(b)(4)]
<br /> SARA Extremely Hazardous Substance(40 CFR 355):Not listed
<br /> SARA Toxic Chemical(40 CFR 372.65):Not listed

<br /> Sects
<br /> Goggles:Wear protective eyeglasses or chemical safety goggles,per OSHA eye-and face-protection regulations(29 CFR 1910.133).Chemical
<br /> safety glasses with side shields are recommended for handling this material.
<br /> Respirator:Wear a NIOSH-approved respirator if necessary.Follow OSHA respirator regulations(29 CFR 1910.134).For emergency or
<br /> nonroutine operations(cleaning spills,reactor vessels,or storage tanks),wear an SCBA.
<br /> Warning:Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
<br /> Other:Wear impervious gloves,boots,aprons,and gauntlets to prevent prolonged or repeated skin contact.
<br /> Ventilation:Provide general and local explosion-proof ventilation systems to maintain airborne concentrations below the OSHA PEL standard
<br /> (Sec.2).If dusty conditions occur,local exhaust ventilation is preferred since it prevents contaminant dispersion into the work area by eliminating
<br /> 1t at its source(Genium ref. 103).
<br /> Safety Stations:Make available in the work area emergency eyewash stations,safety/quick-drench showers,and washing facilities.
<br /> Contaminated Equlpment:Never wear contact lenses in the work area:soft lenses may absorb,and all lenses concentrate,irritants.Launder
<br /> contaminated clothing before wearing again Remove this material from your shoes and equipment.
<br /> Comments:Never eat,drink,or smoke in work areas.Practice good personal hygiene after using this material,especially before eating,drinking,
<br /> smoking,using the toilet,or applying cosmetics.

<br /> Storage Requirements:Store this material in tightly sealed containers away from acidic materials in a clean dry,ventilated area.Prevent
<br /> physical damage to containers.
<br /> Engineering Controls:Avoid dust inhalation,body contact,contact with acidic materials,and heating to decomposition.Note that anhydrous
<br /> trisodium phosphate and lower hydrates are more alkaline than Na3PO4-121-11.O on a weight basis.
