Earnest Ridlon,

The question that was originally asked involved the question of safety in the
workplace. This requires consideration of the manner in which the UV lamps are
operated in the workplace. All UV lamps from reliable suppliers come with an
air flow system designed to evacuate heat and ozone from the immediate
environs of the lamp. The UV safety enclosure (cure chamber or light shield)
encloses the cooling air and any ozone produced. The exhaust system removes it
completely and prevents even traces of ozonefrom being present in the work
area. In general, the higher the power of the lamps, the greater the airflow.
As a consequence there is a steady state value of 0.02 ppm.
