Lamp emits UV rays of 185nm and can kill most germs and
microorganisms. This lamp emits ozone. Ozone gas (O3) is generated by the conversion of oxygen (O2) in the air by UV energy in the range of approximately 110–200 nm. Ozone is extremely toxic and will cause serious health problems if inhaled in excess of allowable limits over a prolonged period of time. For more information on allowable limits, please refer to the ACGIH (American Conference of Governmental Industrial Hygienists) publication, “TLVs and BEIs” (Threshold Limit Values and Biological Exposure Indices).
