Trisodium phosphate; Sodium orthophosphate; Trisodium orthophosphate

DO NOT make a person throw up.

If the chemical is on the skin or in the eyes, flush with lots of water for at least 15 minutes.

If the chemical was swallowed, immediately give the person water or milk. DO NOT give water or milk if the patient is vomiting or has a decreased level of alertness.

If the person breathed in the poison, immediately move him or her to fresh air.

Determine the following information:

• The patient's age, weight, and condition
• The name of the product (ingredients and strengths, if known)
• The time it was swallowed
• The amount swallowed

The National Poison Control Center (1-800-222-1222) can be called from anywhere in the United States. This national hotline number will let you talk to experts in poisoning. They will give you further instructions.

This is a free and confidential service. All local poison control centers in the U.S. use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.

Some or all of the following procedures may be performed:

• For swallowed poison
  • Endoscopy -- the placement of a camera down the throat to see the extent of burns to the esophagus and the stomach
  • Give IV fluids
  • Admission to the hospital
  • Give an antidote
  • Treat the symptoms
• For inhaled poisons
  • A breathing tube may need to be inserted
  • Oxygen
  • Admission to the hospital or to the intensive care unit
  • Bronchoscopy (inserting a camera down the throat into the airway to evaluate the extent of burns to the airway and lungs)
• For skin exposure
  • Irrigation (washing of the skin), perhaps every few hours for several days
  • Skin debridement (surgical removal of burned skin)
  • Admission or transfer to a hospital that specializes in burn care

How well a patient does depends on the strength of the chemical and how fast the poison was diluted and neutralized. Extensive damage to the mouth, throat, eyes, lungs, esophagus, nose, and stomach are possible.

The ultimate outcome depends on the extent of this damage. Damage continues to occur to the esophagus and stomach for several weeks after the poison was swallowed, and death may occur as long as a month later.
