9. Risk Group 3 Safety
To protect untrained end users (as cinema visitors) the installation shall comply with the following installation requirements: Opera-
tors shall control access to the beam within the hazard distance or install the product at the height that will prevent spectators’ eyes
from being in the hazard distance. Radiation levels in excess of the limits will not be permitted at any point less than 2.0 meter (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 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.
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
fi xed 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 fl oor 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 suf
fi ciently 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.

Regarding the SH Distance: For Cinema applications, the distance must be >2m. For Concert applications,
the distance must be >3m.
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 suf
fi cient 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.
On image 1-2 a typical setup is displayed. It must be veri fi ed 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.
