Hydrogen Peroxide Health & Safety Tips

What is Hydrogen Peroxide?

Hydrogen peroxide was first discovered in the early 19^th century, but the pure chemical was not produced until 1894. Today, this chemical is produced in quantities of more than 2 million tons worldwide each year.

Hydrogen peroxide is a chemical compound usually produced as a diluted solution. This colorless, slightly viscous chemical has a somewhat sharp odor. Pure hydrogen peroxide poses some extreme health risks, and diluted solutions of 3-30 percent can cause potential hazards as well. As a result, hydrogen peroxide should be handled and stored with care whether at home or in the workplace.

Read on for safety tips about handling and storing this chemical safely, and how to manage accidental exposure.

Common Uses of Hydrogen Peroxide

Hydrogen peroxide is available most commonly as an aqueous solution, usually at 3 or 6 percent concentrations for household use. In laboratories, 30 percent hydrogen peroxide is used. Commercial-grade peroxide at as high as 98 percent purity is also available, but it’s important to remember that the higher the concentration, the higher the potential health risks. This chemical is used in a variety of applications, including:

• Bleaching paper and pulp
• Mild laundry detergent bleach
• Disinfectant
• Cosmetic hair bleach
• Flour bleaching agent
• Acne treatment
• Wastewater treatment
• First aid

Hazards Associated with Hydrogen Peroxide

In high concentrations in laboratory or industrial settings, hydrogen peroxide can pose serious health and safety hazards. Hydrogen peroxide is a strong oxidizer (moderate oxidizer in lower concentrations), and can be corrosive to the eyes, skin, and respiratory system. This chemical can cause burns to the skin and tissue damage to the eyes.

Take special caution to avoid contact with hydrogen peroxide mist. Household-grade concentrations of this chemical are generally considered safe to use, but should never be ingested. Due to these potential hazards, hydrogen peroxide should be handled with care.

Hydrogen Peroxide Safety, Handling & First Aid

When handling moderate-to-high concentrations of hydrogen peroxide in the workplace, ensure eyewash stations and safety showers are accessible, and use splash goggles, gloves, and an approved vapor respirator.

In the event of exposure to hydrogen peroxide, seek medical attention and follow these first aid guidelines:

• Inhalation—Seek fresh air. If victim’s breathing is difficult, administer oxygen. If breathing is absent, give artificial respiration and seek medical attention immediately.
• Eye Contact—Remove contact lenses if present. Immediately flush eyes with plenty of water for at least 15 minutes, and seek medical attention.
• Skin Contact—Flush skin with plenty of water and cover irritated skin with an emollient. Remove contaminated clothing. In case of serious skin exposure, use disinfectant soap and an anti-bacterial cream and seek medical attention.
• Ingestion—Do NOT induce vomiting. Loosen tight clothing. Never give anything by mouth to an unconscious person. Seek medical attention.

Storing & Disposing of Hydrogen Peroxide

Keep hydrogen peroxide away from sources of ignition, heat, and moisture, storing in a tightly closed container. Keep away from incompatible materials such as organic materials, metals, acids, alkalis, combustible materials, and oxidizing agents. This chemical must be disposed of in accordance with federal, state, and local environmental control regulations.
