INFORMATION AND WARNING ABOUT POTENTIAL HEALTH ISSUES
RELATED TO MERCURY VAPOR
This projector is using an extremely bright UHP™ lamp for
illumination to attain the desired high brightness image.
This technology is similar to other high-pressure discharge lamps
that are extensively used in cars, street lights and other lighting
appliances today. These lamps, like fluorescent lighting, contain
small amounts of mercury. The amount of mercury present in a
lamp is far below the limits of danger set by the authorities.
It is very important that lamps containing mercury are treated
properly to minimize potential health hazards.
The UHP™ lamp, like any other high brightness projector lamp, is
under high-pressure when operating. While the lamp and the
projector are carefully designed to minimize the probability of
lamp rupture, the lamp may break while operating and small
amounts of mercury vapor may be emitted from the projector.
The probability of rupture increases when the lamp reaches its
nominal life. It is therefore highly recommended that the lamp is
replaced when the rated lifetime is reached.
As a general precaution, secure good ventilation in the room
when operating the projector. If lamp rupture occurs, evacuate
the room and secure good ventilation. Children and pregnant
women in particular should leave the room.
When replacing a worn lamp, dispose of the used lamp carefully
by proper recycling.
Mercury is a naturally occurring, stable metallic element that
may pose a safety risk to people under certain conditions.
According to the Public Health Statement for Mercury published
by the Agency for Toxic Substances and Disease Registry
("ATSDR", part of the United States Public Health Service), the
brain, central nervous system and kidneys are sensitive to the
effects of mercury, and permanent damage can occur at
sufficiently high levels of exposure. Acute exposure to high
concentrations of mercury vapor can cause conditions such as
lung and airway irritation, tightness in the chest, a burning
