First Aid Measures

Ingestion
The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. Activated charcoal activated charcoal binds most toxic agents and can decrease their systemic absorption if administered soon after ingestion. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
Inhalation
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
Skin
Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes.
Eyes
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.

Handling and Storage

Storage
Keep containers tightly closed in a well ventilated area away from food products. Keep away from heat and water. If allowed to pick up moisture it will form a hard cake.
Handling
Avoid creating and breathing dust. Use dustless systems for handling, storage, and clean up so that airborne dust does not exceed the PEL. Use adequate ventilation and dust collection. Practice good housekeeping. Do not permit dust to collect on walls, floors, sills, ledges, machinery, or equipment. Use good personal hygiene practices. Wash hands before eating, drinking, smoking, or using toilet facilities. Promptly remove soiled clothing and wash before reuse. Shower after work using plenty of soap and water.

Hazards Identification

Inhalation
This material is a dust or may produce dust. Breathing this material may be harmful or fatal. Symptoms may include severe irritation and burns to the nose, throat, and respiratory tract.
Skin
Can cause severe skin irritation. Symptoms may include redness and burning of skin, and other skin damage.
Eyes
Can cause permanent eye injury. Symptoms include stinging, tearing, redness, and swelling of eyes. Can injure the cornea and cause blindness.
Ingestion
Swallowing this material may be harmful or fatal. Symptoms may include severe stomach and intestinal irritation (nausea, vomiting, diarrhea), abdominal pain, and vomiting of blood. Swallowing this material may cause burns and destroy tissue in the mouth, throat, and digestive tract. Low blood pressure and shock may occur as a result of severe tissue injury.
Hazards
Behavior in fire: May melt with loss of steam. Sodium phosphates

Exposure Controls/Personal Protection

Personal Protection
US bureau of mines toxic NIOSH approved respirator; protective gloves, chemical-type goggles, full-cover clothing.
Respirators
Respiratory protection (supplied-air respirator with full facepiece or self-contained breathing apparatus) should be available where these compounds are manufactured or used and should be worn in case of emergency and overexposure.
Exposure Effects
The toxological properties of this substance have not been fully investigated.
Exposure limit(s)
Trisodium phosphate:-AIHA Workplace Environmental Exposure Limit: 5 mg/m3 (15-minute STEL)

Fire Fighting Measures

Fire Fighting
Use appropriate extinguishing media for the suppression of the exposure fire. Contain runoff.
Fire Potential
Nonflammable.

Accidental Release Measures

Small spills/leaks
Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent dust cloud. Avoid inhalation of asbestos dust.

Stability and Reactivity

Incompatibilities
Aluminum, moisture, strong mineral acids.
Stability
Rapidly absorbs. Water if exposed to moist atmosphere. Dried sodium phosphate.
Decomposition
When heated to decomposition it emits toxic fumes of sodium oxide and POx.
Combustion Products
Fire may produce irritating, corrosive and/or toxic gases.
