High Brightness Precautions: Hazard Distance - Barco HDQ 4K35 User And Installation Manual

• Possible explosion hazard: Always keep in mind the caution below:
CAUTION: Xenon compact arc lamps are highly pressurized. When ignited, the normal operating
temperature of the bulb increases the pressure to a level at which the bulb may explode if not
handled in strict accordance to the manufacturer's instructions. The bulb is stable at room
temperature, but may still explode if dropped or otherwise mishandled. Whenever the lamp house,
containing a xenon lamp, has to be dismantled or whenever the protective container or cloth has to
be removed from the xenon lamp, authorized protective clothing MUST be worn!
Authorized protective clothing for xenon lamp handling
WARNING: Always wear face protection (full face shield) when handling xenon lamps.
WARNING: Always wear protective clothing (welder's jacket) when handling xenon lamps.
WARNING: Always wear clean leather gloves with wrist protectors when handling xenon lamps.
To prevent battery explosion
• Danger of explosion if battery is incorrectly installed.
• Replace only with the same or equivalent type recommended by the manufacturer.
• For disposal of used batteries, always consult federal, state, local and provincial hazardous waste disposal
rules and regulations to ensure proper disposal.

1.3 High Brightness precautions: Hazard Distance

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
chapter "HD in function of modifying optics", page 16.
To protect untrained end users (as cinema visitors, 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' 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 (SW)
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 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
6.6.3.5.
The installer and 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, separation height, barriers,
