These values are minimum values and are based on the guidance provided in IEC 62471-5:2015 section
6.6.5.
The end user 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, barriers, detection system or other
applicable control measure shall prevent hazardous eye access to the radiation within the hazard distance.
For example, projectors that have a HD greater than 1 m 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 meter above the
floor level. In non-cinema environments where unrestrained behavior is reasonably foreseeable, the minimum
separation height should be greater than or equal to 3.0 meter to prevent potential exposure, for example by
an individual sitting on another individual's shoulders, within the HD. For example, a sufficiently large
separation height may be achieved by mounting the image projector on the ceiling or through the use of
physical barriers.
For applications installed in the USA market the above limits for cinema like environments do not apply. The
relevant minimum separation height is 2.5m (8,2 ft) by the FDA CDRH. Non cinema like environments require
2.5 meter (8.2 ft) separation height and 1.0 meter (3.3 ft) separation width for areas where restrained behavior
is to be expected. All other areas require 3.0 (9.9 ft) separation height.

Based on national requirements, no person is allowed to enter the projected beam within the zone between
the projection lens and the related hazard distance (HD). This shall be physically impossible by creating
sufficient separation height or by placing barriers. The minimum separation height takes into account the
surface upon which persons other than operator, performers or employees are permitted to stand.
OnImage 1-2 a typical setup is displayed. It must be verified if these minimum requirements are met. If
required a restricted zone (RZ) in the theater must be established. This can be done by using physical barrier,
like a red rope as illustrated in Image 1-2.
The restricted area sticker can be replaced by a sticker with only the symbol.
