We use UV curing. The UV lamps will create ozone, but not massive amounts. Ozone has an ACGIH TWA of 0.05 to 0.2 ppm. Ozone in high levels is thought to attack brain cells. If you are already ventilating to control heat, then you shouldn't have a problem. UV lamps use a lot of power, so your wasting money if you leave them on when you don't need them. In addition, you will shorten their life span. UV lamps degrade in intensity over time. I'm not sure why anyone would sniff the lamps. There are some amounts of monomers that are volatilized during the curing due to the intense heat. Sniffing the ozone off the lamps should minimal. The larger the lamp, the more the ozone.
