High Brightness precautions: Hazard Distance (HD)
HD
Hazard Distance (HD) is the distance measured from the projection lens at which the intensity or the energy per surface
unit becomes lower than the applicable exposure limit on the cornea or on the skin. The light beam is considered (to
be) unsafe for exposure if the distance from a person to the light source is less than the HD.
Restriction Zone (RZ) based on the HD
The HD depends on the amount of lumens produced by the projector and the type of lens installed. See next chapter"HD in function
of modifying optics", page 8 .
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 do not apply. The relevant minimum separation height is 2.5 meter (8.2
ft) and the separation width is de
fi
ned as 1.0 meter (3.3 ft) by the FDA CDRH.
