Hydrogen Peroxide

Extremely irritating to the eyes, skin and respiratory system and contact with the liquid can cause serious burns. Known animal carcinogen, repeated exposure can cause chronic respiratory irritation or lung collapse.  Inhaling high concentrations may result in seizures, cerebral infarction or cerebral embolism.

Peracetic Acid

Peracetic Acid is a primary irritant, known tumorigen and possible animal carcinogen. Low exposure can result in severe irritation or burning of the skin, eyes, nose, throat and lungs. Higher exposures can cause pulmonary edema, ciculatory, esophageal, liver and kidney affects. For more information, see Health Risks of Peracetic Acid.
