UV sanitation lights are highly effective against COVID-19 corona virus. Compared to traditional liquid cleaning agents, the powerful lamps disinfect surfaces or objects without direct contact.
Safety must be prioritized when using UV sanitation lights, as the units release light beams in the UV-C range (wavelengths ranging between 200 nm and 280 nm) during use. This range is considered to be harmful to human eyes and skin, which can cause corneal injuries, erythema (skin burns) or skin cancer.
Below are some general guidelines for safe operation of UV sanitation lights:
Never look directly at the light when it is activated
Use protective eye and face gear
Cover the hands, arms, neck, legs and other exposed body parts
Setup signs, markers or cones around the area to warn others of ongoing sanitation
Do not handle a broken or cracked UV lamp with bare hands
Additionally, we recommend using respiratory masks when performing UV sanitation in potentially contaminated areas. These vital safety accessories have two benefits: prevents individuals from breathing in deadly viruses/toxic chemicals and reduces direct contact when touching the face/mouth.
When using ultraviolet (UV) light for disinfection, there are several safety precautions to consider.
When using ultraviolet (UV) light for disinfection, there are several safety precautions to consider. These units are equipped with lamps that emit the UV-C range (wavelengths ranging between 200 nm and 280 nm). Long-term intense exposure to this range is harmful to human eyes (corneal injuries) and skin (erythema/skin cancer). Eye-related burns caused by UV light may feel like getting sand in the eye. Because of this, individuals should proactively ensure safety standards are properly observed at all times during operation of the light.
Minimizing Exposure
As a general guideline, individuals should minimize exposure to UV-C light beams from artificial light sources when possible. Looking directly at the lamp at close distances is not recommended. At times when exposure to the light is unavoidable (for example, when using UV handlamps to disinfect a surface or object), use protective eyewear such as glasses, covered visors or full face masks. Cover as much of the hands, arms, legs and neck as possible. Avoid touching a disinfection lamp that is on.
During large-scale sanitation with UV disinfection carts, people should not be present inside the room. Block off access to the general area by setting up signs, markers or cones around entrances and connecting hallways. For designated sanitation areas, a permanent warning sign can be used. Close and cover all windows to contain stray UV-C light beams in the room and prevent exposure to external locations.
When deploying UV lights, direct the lamp toward the target surface, area or object before activation. Do not stand in front of the lamps when turning on the UV disinfection cart. After sanitation, power down the UV light before entering the room or handling the cart.
Light Maintenance and Care
Periodically check the UV lamp before and after use for damage (especially when experiencing light flicker). If the lamp becomes too hot to touch, allow it to cool down before inspection. Do not handle broken or cracked UV bulbs with bare hands.
Protection from infectious viruses and bacteria should be top priority during UV sanitation. Wearing respiratory masks while performing UV disinfection is an effective way to avoid breathing in harmful microbes and chemicals (such as concentrated cleaning solutions). It also reduces direct contact with skin, when touching the face and mouth.
