Health Hazard Evaluations – FAQs

If you are currently an employer, employee, or union official in a workplace where employees’ health and well-being is affected by the workplace you can request a health hazard evaluation. If a field investigation is needed, we will evaluate the current workplace conditions and employee health concerns and make recommendations on how to reduce or eliminate any identified hazards.
Otherwise, we will send you information or refer you to another agency.
Requests can be made in writing or online at https://www.cdc.gov/niosh/hhe/request.html.

Our staff has experience with many types of hazards. These include chemicals, particulates, noise, radiation, biological agents, ergonomics, heat, and stress. For chemicals and other substances, we can look at exposures that people breathe in and exposures that get into the body through the skin.

Yes, our staff will not disclose the name of the employees who request the evaluation to the employer when that choice is marked on the request form. NIOSH also protects individually identifiable medical information according to federal law. If you have concerns or questions about confidentiality please call 1-513-841-4382 to speak with a member of our staff.

The evaluation is done at no cost to the employer or employees.

Once the evaluation is complete, a report is prepared and sent to the employer and employee representatives. Employees can request a copy of the report by emailing us at HHERequestHelp@cdc.gov or by calling 513-841-4382. Most reports are also posted on our website (https://www2a.cdc.gov/hhe/search.asp) and are sent to the Occupational Safety and Health Administration and the relevant state health departments.

NIOSH is not an enforcement agency for workplace standards, so recommended changes do not have to be made. However, our experience has shown that many employers address problems identified in our reports to improve the health and safety of their workforce.

Call 1-513-841-4382 or send an email to HHERequestHelp@cdc.gov and our staff will respond.
