With the threat of Covid-19 still lingering in the air and affecting every aspect of our lives, we are left wondering how we can effectively and safely disinfect our surroundings to help protect ourselves from the virus.
Hospitals and some doctor’s offices use UV light to sterilized equipment and even entire rooms. If they can do it surely, the average business or homeowner can do the same, right? It sounds safe and a lot less messy and irritating than harsh chemicals. But the reality is that it is not safe to use it as a practical and everyday cleaning method.
UV light can damage human tissue and even cause extreme injury to softer areas such as the eyes. When hospitals and labs use it to disinfect rooms and equipment, there are no people around to be injured. The light needs to be so bright and intense to be effective that anyone in the room would suffer immediate injury to their skin and eyes, causing permanent damage and even blindness.
UV light can be used to sterilize PPE and medical equipment as long as safety measures such as protective gear are worn or there are no people in the room. Some companies have tried to capitalize on UV light disinfecting products such as UV wands. If misused, these devices can cause lasting injury.
Experts advise if you would like to use the sun to disinfect PPE gear such as masks, they can be put in a glass jar in the hot sun for several hours. Most surfaces can be safely be cleaned with bleach or alcohol and other household disinfectants.
The world is still learning about the best ways to stay safe and prevent the spread of the novel coronavirus. It is best to leave the UV light disinfecting procedures to the trained professionals.
