Hazards Identification
Ingestion
Serious gi complications have resulted from the ingestion of concentrated solutions and enemas with dilute peroxide solutions.
Serious gi complications have resulted from the ingestion of concentrated solutions and enemas with dilute peroxide solutions.
Inhalation
Inhalation of vapors from concentrated (greater than 10%) solutions may result in severe pulmonary irritation. Interstitial lung disease and respiratory arrest have also been reported following massive exposures.

Skin
Dermal exposure to dilute (3%) solutions generally results in a bleaching of the affected area in association with a tingling sensation and lasts 2 to 3 hours, if washed promptly after contact.
