Precautions : The following precautions should be taken while using UV lamps:
1) TJV lamps must always be properly shielded.
2)Wear approved goggles when working with or close to the source.
3) As a minimum precaution, view through pyrex glass as this material absorbs UV light and is thus largely opaque to radiation of this wavelength.
4) Protect your skin with thick cloth or by suitable barrier cream if necessary.
5 ) Ensure good ventilation to guard against the dangers of inhaling ozone, which can be produced by the effect of UV on the oxygen in the air.
