Safety Guidelines for Ultraviolet Radiation in the Laboratory

Overexposure to UV radiation may be dangerous, particularly to the eyes. Less exposure isn’t safe also, as it can cause burning and reddening of the eyes and skin. So before you buy UVC lamps (ซื้อหลอด UVC, which is the term in Thai) here are safety considerations for UV radiation in the Laboratory.

UV Safety Instructions

The most straightforward safety precaution is to avoid exposure to a UV source. Here are the safety instructions to mitigate UV risks:

  •  Beam paths that are enclosed should be used wherever possible
  • When the source is idle, always use an electronic or manual shutter to close the beam
  • Do not look straight at the beam
  • Reduce access to places UV source is high
  • Cover neck and arms and reduce exposure
  • Always protect your eye and wear gloves
  • Warning signs must be visibly posted at entrances to regions that use UV sources

Protective Gloves

Operators must protect their hands as hands are more exposed to ultraviolet radiation when handling the fixtures in the beam. These gloves are usually designed to absorb perspiration to enhance removal and wearing.

Laser and UV Radiation Warning Signs

Look out for adhesive-backed signs and lighted signs with ultraviolet and laser radiation warnings. Lighted signs are visible signs posted in areas that involve high laser radiation or UV exposure.

You can operate these signs in any of these three modes: flashing light with a louder beep, continuous light, and flashing light.

UV Safety Spectacles and Goggles

Goggles and spectacles are designed to shield the eyes from UV radiation. The goggles incorporate a soft frame with an adjustable headband. The screened ventilation ports lessen the build-up of moisture. They are more of a visibility purpose than spectacles. Goggles are worn over 50mm lenses prescription glasses.
