What to Do If Exposed to Peracetic Acid

Peracetic acid is a strong disinfectant commonly used in industrial and healthcare settings, but it can pose serious health risks if mishandled. If you come into contact with this chemical, immediate action is essential.

If peracetic acid touches your skin or eyes, flush the affected area with plenty of running water for at least 15 minutes. Do not delay—rinsing quickly can minimize tissue damage and reduce the risk of chemical burns. Even if symptoms seem mild, seek medical attention right away. This chemical can cause irritation, redness, or more severe reactions depending on concentration and exposure time.

In the case of a spill, safety should be the top priority. Never attempt to clean it up with bare hands. Instead, absorb the liquid using an inert, non-reactive material like sand or vermiculite. Alternatively, dilute the spill immediately with a large volume of water to reduce its strength, then carefully wash it away. Make sure the area is well-ventilated to avoid inhaling fumes, which can irritate the respiratory tract.

Always wear appropriate personal protective equipment—gloves, goggles, and a face shield—when working with peracetic acid. Having an emergency plan in place, including easy access to safety showers and eyewash stations, can make a critical difference.

Remember, even brief exposure can be harmful. When in doubt, always consult a healthcare professional or contact a poison control center. Proper handling, prompt response, and awareness are key to staying safe around powerful chemicals like peracetic acid.
