U S Environmental Protection Agency provides a guideline of 0 08 PPM for safe levels of ozone in the workplace 1 The cooling exhaust air from the lamp housings using Xenon quartz flash lamps produces ozone above the EPA standard If the workplace is not vented to reduce the ozone level below the EPA standard then the cooling air discharged from the lamp housing must be either removed or filtered through a charcoal filtering system The Xenon germisil lamp does not produce ozone and therefore the cooling air exhausted from the lamp housing does not have to be removed or filtered 2 Note that ozone levels will vary as temperature and humidity change Use an ozone sensor to detect ozone and estimate ozone levels in parts per million ECO Sensors Inc Model A 20ZX 1 800 472 6626 or equivalent measures ozone and provides the data necessary to determine PPM ozone levels Part 810 0057 Rev E 3 9 06 2 5 XENON CORPORATION RC 742 Pulsed UV System Installation amp Maintenance Manual 3 For further information on ozone in the workplace order the ozone technical note from your Xenon sales representative 2 5 Mounting and Interconnection Stability Precautions WARNING Personal injury or potential equipment damage can result from improper mounting or interconnection instability 1 Read all warnings and cautions listed in the installation instructions 2 The equipment allows for components to be mounted in any vertical or horizon
