Safety Precautions for Working with UV Light: A Guide for Experts

Despite the many advantages of germicidal UV lamps, they can be hazardous if not used with the proper safety precautions. To ensure safety when working with UV light, it is essential to take the following steps: limit access to areas where UV sources are used, place warning signs at the entrance of laboratories or other work areas that use UV sources, wear protective goggles and gloves, cover your arms and neck, and limit exposure time. Never look directly at the beam. It is important to note that UV radiation is divided into four parts: UV under vacuum (100-200 nm), UVC (200-280 nm), UVB (280-315 nm) and UVA (315-400 nm). To use direct germicidal products against UV-C rays, personal protective equipment must be worn: gloves, a long-sleeved shirt with no gaps between the cuffs and gloves, and a UV-blocking face protector to protect your eyes and exposed skin.

Under no circumstances should a direct UV-C germicidal unit be allowed to work with people, plants, or animals present in the operating area. If there is a possibility that the eyes and face may be exposed to UV radiation, a polycarbonate face protector with the ANSI Z87,1-1989 UV certification should be used to protect the eyes and face. Additionally, installing an indicator light outside a room is one more step to ensure that no one enters while a germicidal UV lamp is on. Environmental Health & Safety can help measure UV emissions and evaluate personal protective equipment to determine its protection against UV rays. In conclusion, it is essential for experts to take all necessary precautions when working with UV light in order to ensure safety. This includes limiting access to areas where UV sources are used, wearing protective gear such as goggles and gloves, covering your arms and neck, and limiting exposure time.

Additionally, it is important to use a polycarbonate face protector with the ANSI Z87,1-1989 UV certification if there is a possibility of exposure to UV radiation.
