2 SAFETY
SUMMARY OF HAZARDS
The hazards encountered in the operation of these illuminator systems are:
Radiation
Lamp explosion
Ozone
Electrical shock
EMI
Heat
The interlock system is designed for your safety. Do not defeat the interlocks.
2.1 UV AND VISIBLE RADIATION
The high intensity UV and VIS radiation of the lamp can permanently damage the cornea, lens, and
retina of the eye, even causing blindness. This damage may not be immediately apparent. The deep UV
is absorbed in the cornea or eye fluids; focused UV, VIS, and NIR can damage the retina. Normal blink
reaction to visible light may not be adequate protection, and a beam of invisible UV or NIR (produced
by spectral filtering) can be most dangerous, as the blink response is not induced. UV radiation can
also cause painful sunburn, and with prolonged exposure, serious burns.
Recommendations
1. Never look directly into the output beam from an arc lamp housing.
2. Do not look at the specular (mirror) reflection of the beam.
3. Always wear UV protective eyewear or facemask, and adequate protection for exposed areas of
skin.
2.2 LAMP EXPLOSION
When Xenon, Mercury and Mercury-Xenon arc lamps are cold, they are under several atmospheres of
pressure and may explode due to internal strains or physical abuse. When hot, all lamps are under a
pressure of many atmospheres and the possibility of violent explosion exists. Fingerprints and
other contaminants left on the lamp cause a deterioration of the envelope during operation and may
lead to lamp explosion.
Recommendations
1. Do not handle a bare arc lamp without safety goggles and adequate protection for exposed areas
of skin.
2. Wear gloves when handling a lamp. Do not touch the lamp envelope with your fingers.
3. Clean the lamp envelope thoroughly with alcohol or a dilute solution of detergent and water if it
comes in contact with skin.
