Responsible laser show producers will keep beams from entering audience areas, or will ensure that audience-scanning beams are at eye-safe irradiance levels. Unfortunately, it is not always possible to tell by eye, or from a video, whether audience beams are too powerful.

It is better to be safe than sorry. Therefore, if you have concerns about the safety of any laser display, contact the venue and also the appropriate government agency(ies).

  • For example, in the U.S. contact the FDA's Center for Devices and Radiological Health, and your state laser agency.
  • In the U.K., contact Public Health England and the local authority for approving shows.
  • Links for agencies can be found on this website’s Links and Resources page.

In March 2015, ILDA asked an FDA representative how the public should contact the agency, if they see a potentially hazardous laser show. The reply was to have the concerned person write a letter to the FDA at the following address:

          U.S. Food and Drug Administration
          Center for Devices and Radiological Health
          Document Mail Center – WO66-G609
          10903 New Hampshire Avenue
          Silver Spring, MD 20993-0002

If the show was done by an ILDA Member (see here for list), you can also file an Ethics Complaint. ILDA can investigate and can take action within the association.

However, any serious problems or concerns should first be addressed with the venue management and government regulators. They have the authority and duty to stop unsafe or illegal laser shows.
