To ensure laser safety, several key measures should be implemented. It is important to ensure that only qualified and trained employees are assigned to install, adjust, and operate laser equipment [1]. Proof of qualification should be available with the operator at all times [1].

Areas where lasers are in use must be clearly marked with standard laser warning placards [1]. When laser transmission is not required, beam shutters or caps should be utilized, or the laser should be turned off [1]. If the laser is left unattended for a substantial period, it must be turned off [1].

Direct the laser beam away from employees [1]. When weather conditions such as rain, snow, dust, or fog are present, the operation of laser systems should be prohibited where practicable [1]. The laser equipment should also bear a label indicating its maximum output [1].

Employees exposed to laser beams must be furnished with suitable laser safety goggles that provide protection for the specific wavelength of the laser and have adequate optical density for the energy involved [2]. All protective goggles should have a label that identifies the laser wavelengths for which they are intended, the optical density at those wavelengths, and the visible light transmission [3].

In industries other than medical, ensure laser equipment is operated and used according to ANSI Z136.1-2007 standards, or a standard offering equivalent or better protection [4]. In medical industries, ensure laser equipment is operated and used according to CSA standard CAN/CSA-C22.2 No. 60601-2-22-01 (R2005) and CSA standard Z386:20, or standards offering equivalent or better protection [5].
