Where Found

Some oven cleaners


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

Home Treatment
Seek emergency medical care immediately. DO NOT INDUCE VOMITING.

If the cleaner is on the skin or in the eyes, flush with lots of water for at least 15 minutes. Move the person to fresh air.

If the cleaner was swallowed, give water or milk IMMEDIATELY. If the patient is vomiting, keep giving water or milk. DO NOT TRY TO NEUTRALIZE the alkali by giving vinegar or lemon juice - this may cause more severe burning.

Before Calling Emergency
Determine the following information:

  • The patient’s age, weight, and condition  
  • Name of product (as well as the ingredients and strength, if known)  
  • The time it was swallowed  
  • The amount swallowed

Poison Control, or a local emergency number
See Poison Control centers for telephone numbers and addresses. Take the container with you to the emergency room.

What to expect at the emergency room

Some or all of the following procedures may be performed:

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

Expectations (prognosis)

The prognosis (probable outcome) depends on how rapidly the alkali is diluted. Extensive damage to the mouth, throat, 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 alkali was swallowed. Death may occur as long as a month later.
