CAS No. 7722-84-1
Hydrogen Peroxide (H₂O₂) is a colorless liquid with a slightly sharp odor. Hydrogen peroxide can cause irritation to the eyes, nose, skin, and throat. Workers may be harmed from exposure to hydrogen peroxide. The level of exposure depends upon the dose, duration, and work being done.
Hydrogen peroxide is used in many industries. In industry, hydrogen peroxide in higher concentrations is used as a bleach for textiles and paper, as a component of rocket fuels, and for producing foam rubber and organic chemicals. It’s also used in medicinal applications and to bleach clothes and hair. Workers may be exposed to hydrogen peroxide through inhalation or contact with the skin. Examples of workers who may be exposed to hydrogen peroxide include the following:
- Workers in poultry plants that use it in chemical disinfectants
- Stylists in beauty salons who use colorant products
- Hospitals and healthcare workers
- Factory workers in plants that manufacture foam rubber
NIOSH recommends that employers use Hierarchy of Controls to prevent injuries. If you work in an industry that uses hydrogen peroxide, please read chemical labels and the accompanying Safety Data Sheets for hazard information. Visit NIOSH’s page on Managing Chemical Safety in the Workplace to learn more about controlling chemical workplace exposures.
The following resources provide information about occupational exposure to hydrogen peroxide. Useful search terms for hydrogen peroxide include “high-strength hydrogen peroxide,” “hydrogen dioxide,” “hydrogen peroxide (aqueous),” “hydroperoxide,” and “peroxide.”
The NIOSH Pocket Guide to Chemical Hazards (NPG) helps workers, employers, and occupational health professionals recognize and control workplace chemical hazards.
The NIOSH Manual of Analytical Methods (NMAM) is a collection of methods for sampling and analysis of contaminants in workplace air, and in the blood and urine of workers who are occupationally exposed.
The Health Hazard Evaluation Program (HHE) conducts onsite investigations of possible worker exposure to chemicals. Search the HHE database for more information on hydrogen peroxide.
- NIOSHTIC-2 search results for hydrogen peroxide—NIOSHTIC-2 is a searchable database of worker safety and health publications, documents, grant reports, and journal articles supported in whole or in part by NIOSH.
- NIOSH Worker Health Study Summaries —NIOSH conducts research to prevent illnesses and injuries in the workplace. The NIOSH Worker Notification Program notifies workers and other stakeholders about the findings of these research studies.
