A laser controlled area is a designated space where access and working procedures are managed because hazardous laser radiation may be present.
The purpose of establishing a controlled area is to reduce the likelihood that unauthorised or unprotected people will be exposed to hazardous laser radiation. Depending on the application, controls may include restricted access, warning signs, barriers, beam enclosures and operating procedures.
Personal protective equipment such as laser safety glasses can provide an additional layer of protection for people who need to work within the area.
The eyewear used should correspond to the laser system operating inside the controlled area. This means checking the wavelength, optical density and relevant protection ratings rather than simply providing generic safety glasses.
Controlled areas can be particularly important for higher-powered industrial lasers, medical laser systems, laboratories and research facilities. The precise controls required depend on the laser classification, installation and operating environment.
A controlled area should also have clearly understood procedures so personnel know when laser radiation may be present and what protective measures are required.
The combination of access control, engineering measures, administrative procedures and suitable laser safety eyewear can significantly reduce the risk of accidental exposure.
