In view of recent events and the spread of COVID-19, effective cleaning and disinfection on a lift are now more important than ever. Bacteria and dirt can hide and be invisible. Shoes can transfer dirt on the lift’s flooring. Lift users’ hands can leave marks on the handrails and grime can hide on the surface of the buttons.
We now know that coronavirus can live on surfaces for up to nine days and survives in the air for a few hours. We also now know that the virus particles are shed through saliva and fluids coughed up from the lungs. And that the virus can also be shed from our feces.
Elevators are one of the most frequently used Public utilities where multiple occupants of a building have a contact overlaps as they are touching metallic push buttons. It’s important to be mindful of the surfaces we all touch, not only for our personal safety but for others around us as well.
It is very important to get the Lifts properly disinfected/ sanitized. To help you, we have created a helpful checklist to a clean lift environment where every passenger feels safe to operate it and travel amongst floors.
Step 0 - Preparation
In the current climate, we’d recommend using a cloth with a sanitizer. Use the damp cloth with circular movements to clean surrounding glass, color coated and stainless steel surfaces. You can use cleaning products which are safe for domestic and commercial use to clean the mirrors. We would advise avoiding sponges as extensive moisture can damage electrical parts such as push buttons.
What you need to know
Cleaning an area with normal household disinfectant after someone with suspected coronavirus (COVID-19) has left will reduce the risk of passing the infection on to other people. Wherever possible, wear disposable or washing-up gloves and aprons for cleaning. These should be double-bagged, then stored securely for 72 hours then thrown away in the regular rubbish after cleaning is finished. If an area has been heavily contaminated, such as with visible bodily fluids, from a person with coronavirus (COVID-19), consider using protection for the eyes, mouth and nose, as well as wearing gloves and an apron
Step 1 - Isolate the lift doors - switch the power off
First and foremost before proceeding to any actions, ensure that:
For home lifts - the lift’s electrical power has been switched off
For passenger and platform lifts - doors have been isolated
Now you can safely manoeuvre in and out of the lift, without worrying about lift doors closing or obstruction. We would advise using relevant signage to notify potential lift users that they cannot use the equipment while you are cleaning. Once you have ensured all precautions have been put in place, you are now ready to clean.
Step 2 - Clean from top to bottom
It is really useful to clean the lift starting from the inside going outside and from top to bottom as this prevents already clean surfaces from being contaminated by dirt and bacteria. It’s always best to use non-corrosive cleaners - no one enjoys a lift ride with lingering smells!
Using a disposable cloth, first clean hard surfaces with warm soapy water. Then disinfect these surfaces with the cleaning products you normally use. Pay particular attention to frequently touched areas and surfaces, such as grab-rails, buttons and door handles.
Step 3 - Cleaning lift buttons and handrails, landing buttons
Use an antibacterial cleaning product to wipe handrails and keypads. Use a microfiber cloth to wipe these areas and remove stacked dirt, dust and hair. Clean the buttons first with smooth delicate strokes.
Avoid spraying directly at the control panel surfaces as there is a high risk of damaging the electrical components inside the keypad. You don’t want the cleaning liquid to seep inside the control operating panel.
Step 4 - Cleaning the elevator car & doors Passenger Lifts-1
Use a damp cloth to clean the lift doors and any steel surface. Alternatively, you can use a non-abrasive cleaner - remember dust and dirt can fall from the ceiling.
You may need a step ladder depending on the height of the elevator to help you reach the ceiling safely. This would allow you to safely clean the ceiling and the high parts of the lift doors and walls.
We would advise you not to use harsh cleaning chemical to clean stainless steel and color-coated surfaces. Those surfaces are sensitive to various cleaning products and you might damage them. To give a shiny result to any stainless steel surface, use a few drops of baby oil and a cloth to wipe and polish them.
Tip: Shoes, trolleys and wheelchairs can transfer all sorts of dirt to your lift car floor, therefore we recommend floor cleaning. There are different flooring types so we recommend brushing and vacuuming carpeted floors and polish and clean tiles and steel floors.
Don’t skip vacuuming the gaps and tracks between the doors at each landing level. Once all large scraps and dirt have been removed, wipe the stainless steel surfaces with a clean damp cloth or by using a non-abrasive cleaner. Remember, these particles can easily be transferred into the office or house space. And we certainly don’t want that to happen!
Once cleaning is complete wash hands regularly with soap and water for 20 seconds, and after removing gloves, aprons and other protection used while cleaning.
Step 5 - Professional Maintenance - Cleaning lift shaft
Following the above steps will ensure that your lift car is clean. However, the cleaning of the pit area is just as important as the interior of the lift car. Only competent and certified engineers have access to clean the lift pit. During regular maintenance, your lift service provider should proceed with removing dirt, trash and debris.
Just think of the accidental drop of small items through the gaps between the doors, such as keys, cards, mobile phones even food! And that’s not all, regular cleaning will prevent moving parts of the lift from rusting and limit pest infections.
The challenge with conventional systems remains that the passengers cannot use the lift while disinfected and the fact that sanitization has to be done repeatedly using the same procedures which can be cumbersome to handle operations and movement both.
Some of the Real time solutions
Air purification systems inside lift cabins
Our car air purifier not only ensures a pollution free air, it also blocks and filter germs. Equipped with dual filters to filter the car air, remove bacteria and other harmful substances in the air, and make the car air clean. The powerful nano-photocatalyst technology and 254nm wavelength ultraviolet lamp can effectively eliminate the 99.9% bacteria in the air of the car. The double filter automatically removes dust and other harmful particles, so you can enjoy fresh and clean air.
UV-C light based systems
A UV-C ultraviolet light, the same type used for sanitizing hospitals, guarantees the complete sterilization of the car surfaces, while a ventilation device with absolute air sanitizing HEPA filter, combined with an activated charcoal membrane, removes viruses and bacteria in the particulate. The air exchange is almost instantaneous and sterilization occurs in the stand-by phase.
Chlorine-di-oxide and UV based systems
Chlorine dioxide slow-release molecular materials can kill virus and bacteria and decompose formaldehyde, etc. Use of Chlorine di oxide as disinfectant does not cause any secondary pollution and has no side effects on the human body. Since some virus and bacteria are carried by the human body, real-time disinfection and sterilization can kill the virus and bacteria at the first time and cut off the transmission, reducing cross infection.
