Direct Contact:
* Skin irritation: Contact with concentrated hydrogen peroxide can cause severe skin irritation, redness, burning, and blistering.
* Eye irritation: Getting hydrogen peroxide in your eyes can cause irritation, redness, and even corneal damage.
* Respiratory irritation: Inhaling hydrogen peroxide vapor can irritate the respiratory tract, causing coughing, shortness of breath, and even pulmonary edema (fluid in the lungs).
Internal Ingestion:
* Gastrointestinal distress: Ingesting hydrogen peroxide can cause severe stomach pain, nausea, vomiting, and diarrhea.
* Tissue damage: Hydrogen peroxide can damage tissues and organs, potentially leading to internal bleeding and organ failure.
* Oxygen toxicity: In high concentrations, hydrogen peroxide can release excessive oxygen, leading to oxygen toxicity, which can damage the lungs and other organs.
Other Hazards:
* Fire hazard: Concentrated hydrogen peroxide is a strong oxidizer and can react violently with flammable materials, posing a fire hazard.
* Environmental damage: Hydrogen peroxide can be harmful to aquatic life and should not be released into the environment.
Important Note:
* The dangers of hydrogen peroxide depend heavily on the concentration. Diluted solutions (3%) are often used as antiseptics and are generally safe for topical use.
* Always follow the instructions provided by the manufacturer.
* Never ingest hydrogen peroxide, and keep it away from children and pets.
If you experience any adverse effects from hydrogen peroxide, seek immediate medical attention.
