![]() UV filters should be considered when deciding on the layout of a workplace using a UVC system. This is important for general protection and awareness in the workplace as well as for maintenance and repairs to the system. ![]() This is sometimes built into a system, but some manufacturers also produce retrofit kits to add an interlock system to a biosafety cabinet.Ī viewport allows a worker to see the UVC lamp without exposing themselves to UVC light. Systems for sanitizing equipment like biosafety cabinets should have some sort of interlock system to stop them from emitting UVC when open. This can ensure that the system is only running when employees are safe from exposure. When this is not possible (like in a system designed to disinfect the air in a working laboratory), the switches should be wired in series or placed in a separate room only accessible to authorized individuals. When possible (for example, for biosafety cabinets), UVC systems should be kept in a separate space from where people work. Here are some of the engineering controls to consider for UVC safety. Engineering Control Measures for UVC SafetyĮngineering control measures for UVC safety are designed to minimize the general exposure to UVC radiation by optimizing UVC systems for the space they are in and the purpose they serve. UVC safety is a multifaceted strategy and involves both preventing exposure through engineering controls and through administrative controls. Acute effects of UVC exposure include:Ĭhronic effects of cumulative UVC exposure include:īecause UVC has the most potential for acute health effects of the three forms of UV light, it’s important that employers and individuals are aware of these risks and take adequate steps to ensure safety. The health effects from UVC can be either acute (short-term) or chronic (long-term). However, it also does not easily penetrate the skin, so most damage from UVC radiation occurs on the surface of the skin or in the eyes, which are much more sensitive than the rest of the skin. Of the three types of UV light, UVC is the most damaging to living tissues because it has the highest energy. Most UVC exposure occurs from germicidal UVC disinfection systems. UVC light from the sun is absorbed by the atmosphere, so the risk of UVC exposure from going outside is minimal. This article discusses some of the safety concerns of UVC radiation and ways that employers and individuals can mitigate these concerns through both engineering controls (about the system as a whole) and administrative controls (providing guidance and equipment to individuals using the system). A wavelength of 253.7nm is most often emitted by low-pressure germicidal lamps. UVC is the highest-energy form of UV radiation and is the type used for disinfection. UV light is classified into different categories based on its wavelength. But it is also used in many industrial applications like germicidal lamps for disinfecting surfaces, air, and even water, blacklight inspection for quality control and law enforcement, and even curing certain industrial materials. UV is all around us because it is made by the sun.

With the purchase of the LD32 UVC, you will receive a 3500mAH 18650 battery that is rechargeable via its unique Micro USB Charging port. Other features of the LD32 UVC include the lightweight design, sturdy pocket clip, and long runtimes. The UVC light should only be used to disinfect inanimate objects. As a reminder, it is prohibited to shine the LD32 UVC light on the human body or animals and should be kept out of children’s reach. The UVC Light also has a protective cover in case of accidental activation. The high-power ultraviolet UVC light can disinfect the most common bacteria and viruses within 30 seconds, making it perfect for close-range disinfection. The auxiliary switches, when pressed simultaneously, will activate the UVC light for disinfection. The main switch controls the power and brightness of the standard white output. This new flashlight has multiple switches, a main switch and two auxiliary switches on the side. It has a maximum output of 1200 lumens and beam visibility of 557 feet. The LD32 is powered by a single 18650 battery. The Fenix LD32 UVC is a new portable flashlight from Fenix that also has a UVC light for disinfection.
