WARNING
8. Mercury lamp burst and gas leak
The mercury lamp is filled with inorganic mercury and a small amount of Ar and Xe deactivated gas. The
pressure inside the cold (room temperature) mercury lamp is as low as the atmospheric pressure. Once
the lamp is lit, the mercury is vaporized, causing extremely high pressure inside the lamp. If the lamp is
damaged or used in excess of its average service life, it may burst and/or its gas may leak.
If the lamp bursts, the broken glass may be scattered and hurt human beings and/or the unit. The gas
inside the lamp (vaporized mercury, Ar and Xe gas) will be released into the air bringing about the danger
of inhaling the mercury vapor. To avoid these dangers and to cope effectively with these abnormal
situations, please read the articles below before using the equipment. When handling the lamps, follow the
instructions in " CAUTION 3. When handling the lamps".
• The inorganic mercury (chemical symbol: Hg, chemical formula: Hg) is said to be less harmful and less
absorbed by human beings than the organic mercury (methyl mercury), but sill is harmful and an
utmost care is needed in handling them.
• Should the lamp burst, or the gas leak, all the personnel must immediately leave the room so as not to
inhale the mercury vapor. Further, thoroughly ventilate the room for at least 30 minutes.
• If you happened to inhale the mercury vapor, immediately rinse your mouth and throat with a plenty
amount of water. If the mercury vapor stick on your skin or get into your eyes, wash it off with a plenty
amount of water likewise. If you feel sick, or notice any sign of illness, please at once consult your
doctor.
• Wait till the lamp and the lamphouse cool down before cleaning up the mess.
• To gather the scattered liquid mercury, use a special material for absorbing the mercury (available from
vendors handling experimental materials). Dispose of them as the special industrial waste or dispose of
them according to the laws or rules of your municipal waste system.
• Pick up the broken pieces of glass with the greatest care so as not to cut your fingers. Put the broken
pieces of glass in a hard container and dispose of them as the special industrial waste or dispose of them
according to the laws or rules of your municipal waste system.
• Ar and Xe deactivated gas inside the lamp are the same as those exist in air. They are harmless.
