Epson Pro L30002UNL 30,000-Lumen HDR Pixel-Shift DCI 4K Laser 3LCD Large Venue Projector (White) - Manual (Page 333)

The HD depends on the number of lumens produced by the projector, the size of the panel(s) used, and
the type of lens installed. HD values are provided in the table below.
To protect untrained end users (such as cinema visitors or spectators), the installation shall comply with
the following installation requirements: Operators shall control access to the beam within the hazard
distance or install the product at the height that will prevent spectators from being in the hazard distance.
Radiation levels in excess of the limits will not be permitted at any point less than 2.0 meters (SH) above
any surface upon which persons other than operators, performers, or employees are permitted to stand
or less than 1.0 meter (SH) lateral separation from any place where such persons are permitted to be. In
environments where unrestrained behavior is reasonably foreseeable, the minimum separation height
should be greater than or equal to 3.0 meters to prevent potential exposure, for example by an individual
sitting on another individual’s shoulders, within the HD.
These values are minimum values and are based on the guidance provided in IEC 62471-5:2015 section
6.6.5.
The installer must understand the risk and apply protective measures based upon the hazard distance
as indicated on the label and in the user information. Installation method, separation height, barriers,
detection systems or other applicable control measures shall prevent spectator access to the projected
light within the hazard distance.
For example, projectors that have a HD greater than 1 meter and emit light into an uncontrolled area
where persons may be present should be positioned in accordance with “the fixed projector installation”
parameters, resulting in a HD that does not extend into the audience area unless the beam is at least 2.0
meters above the floor level. In environments where unrestrained behavior is reasonably foreseeable,
the minimum separation height should be greater than or equal to 3.0 meters to prevent potential
exposure, for example by an individual sitting on another individual’s shoulders, within the HD.
