Cautionary information regarding UV products

UV blocking eye wear

  • Do not expose your eyes or skin to direct UV irradiation.
  • When using UV illumination, be sure to wear UV blocking eye wear and avoid looking at irradiating parts (emitting parts).
  • Do not turn on UV-LED irradiating parts (emitting parts) if they are facing someone's eyes.
  • Wear long sleeves and gloves to protect your skin from UV irradiation.
  • Thoroughly educate all those involved near the product about the dangers of UV LEDs.
