Anti-rust products contain various toxic substances that can be ingested by small children, or they may be accidentally inhaled if they are being used in a small, poorly-ventilated area, such as a garage.

• nitrites
• oxalic acid
• hydrocarbons
• chelating agents

• various anti-rust products

• Respiratory
  • Breathing difficulty (from inhalation)
  • Throat swelling (which may also cause breathing difficulty)
• Eyes, ears, nose, and throat
  • Severe pain in the throat
  • Severe pain or burning in the nose, eyes, ears, lips, or tongue
  • Loss of vision
• Gastrointestinal
  • Severe abdominal pain
  • Vomiting
  • Burns of the esophagus (food pipe)
  • Vomiting blood
  • Blood in the stool
• Heart and blood vessels
  • Hypotension (low blood pressure) develops rapidly
  • Collapse
• Skin
  • Irritation
  • Burn
  • Necrosis (holes) in the skin or underlying tissues
• Blood
  • Severe change in pH (too much or too little acid in the blood, which leads to damage in all of the body organs)
  • Methemoglobinemia, a condition where the red blood cells have reduced capacity to carry oxygen to the tissues
• Kidneys
  • Kidney failure

Seek emergency medical care immediately. If the patient is awake, give water to dilute. Do not induce vomiting.

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

They will instruct you if it is necessary to take the patient to the hospital. See Poison Control centers for telephone numbers and addresses. Take the container with you to the emergency room.

Some or all of the following procedures may be performed:

• For swallowed poison
  • Placement of a tube down the nose and into the stomach (a nasogastric tube, or an NG tube) to wash out the stomach
  • Activated charcoal administration
  • 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

The prognosis (probable outcome) depends on how rapidly the poisons were 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 kidneys, liver, esophagus and stomach for several weeks after the substance was swallowed, and death may occur as long as a month later.
