What to Do If Exposed to Peracetic Acid

Peracetic acid is a powerful chemical commonly used for sterilization in food processing and healthcare settings. While effective, it can pose serious health risks if mishandled. If you come into contact with it, quick and proper first aid is crucial.

Skin exposure requires immediate action. Remove any contaminated clothing or shoes without delay—don’t risk spreading the chemical further. Then, flush the affected area with lukewarm water for at least 15 minutes. Do not try to neutralize the acid with other substances; water is the safest and most effective option. Even if the skin appears unharmed, seek medical attention right away. The effects of peracetic acid can be delayed, and early evaluation by a healthcare professional is essential.

Eye contact is especially dangerous. If the acid gets into the eyes, act quickly. Begin flushing with clean, running water immediately. Make sure to hold eyelids open to ensure thorough rinsing. Remove contact lenses if present and if you can do so easily—this helps prevent ongoing irritation. Continue flushing for a full 15 minutes, and don’t assume the problem is resolved just because discomfort lessens.

Always call for emergency medical assistance after exposure. Do not wait for symptoms to worsen. In a workplace setting, ensure that safety data sheets (SDS) are accessible and that all personnel are trained in handling such incidents. Proper personal protective equipment—like gloves, goggles, and face shields—should always be worn when working with peracetic acid.

Remember, fast, calm response can make a big difference. Knowing the right steps isn’t just about treating injury—it’s about preventing long-term damage.
