Is UVC Safe?

UVC light emitting sources have to be used along with precautions to ensure safe usage. UV range of Electromagnetic radiation extends 10nm to 400nm. Depending on the wavelength and time of exposure, UV radiation can cause harm to your eyes and skin.

The UV spectrum is into three parts. UVA (315nm to 400nm), UVB (280nm to 315nm), UVC (200nm to 280nm) Decreasing wavelengths correspond with higher frequency radiation and a more elevated amount of energy per photon.

UVB radiation is widely recognized for its harmful effects on human skin and links to skin cancer. Each UV band creates different risks for humans. UVC radiations are wavelengths shorter than 280nm. They are absorbed by the atmosphere and no natural UVC radiation reaches the surface of the earth. Available due to human-made artificial sources.

The further away the UVC source is from a human, the lesser dose he is exposed to, the absorption length of UVC radiation in human skin is extremely short, so almost no UVC radiation Can reach the living cells in the skin, all the absorption occurs in the dead cell layers.

If you have prolonged direct exposure to UVC light, Temporary eye and skin damage have been exhibited, such as cornea injury, which heals after a few days. Safety instructions include protecting skin (in particular open wounds) and eyes from UVC radiation.

Acute (short-term) effects include redness or ulceration of the skin. At high levels of exposure, burns can be severe. For chronic long term exposures, there is a cumulative risk which depends on the amount of exposure leads to premature aging of the skin and skin cancer.

Use UV goggles or full face shields and cover any exposed skin using lab coats, nitrile gloves, or other lab attire. UVC exposure is reduced through product safety design considerations and controls. Ensure that you follow the manufacturer’s instructions and recommendations for proper use of any UV system should be kept for reference to reduce hazardous exposure.

If you are exposed to UV radiation for a small amount of time, it is usually not severe and symptoms can be delayed. The following actions are recommended: See an ophthalmologist if eye damage is suspected, Treat skin lesions immediately, Follow your organization’s EHS incident reporting procedure. Documenting the date and time of the event, persons involved, equipment involved and type of injury.
