EVS technicians must be mindful of using colour-coded cleaning tools to prevent cross-contamination
Environmental Services (EVS) teams in healthcare settings are responsible for maintaining clean and sanitary conditions to ensure patient safety and a positive experience. EVS technicians play a crucial role in infection prevention and control, including cleaning and disinfecting patient rooms, medical equipment, and other areas within healthcare facilities.
Colour-coded cleaning is a widely adopted practice in commercial spaces, including hospitals, to prevent cross-contamination and maintain hygiene. By assigning specific colours to different areas, such as blue for general spaces, green for kitchens, red for bathrooms, and yellow for high-risk areas, EVS technicians can easily identify the appropriate tools for each task, reducing the risk of spreading contaminants.
The British Institute of Cleaning Science (BICSc) has developed guidelines and a colour-coding system to enhance the effectiveness of cleaning practices. One of their golden rules is to "always work from the cleanest area toward the dirtiest area," significantly reducing the chances of cross-contamination. Implementing colour-coded practices ensures that cleaning equipment is restricted to its designated areas, minimising the spread of pathogens.
EVS technicians must be diligent in adhering to the colour-coding system to prevent cross-contamination. Regular inspections and replacements of worn or faded cleaning supplies are necessary to maintain the effectiveness of the system. Proper cleaning, disinfection, and drying of reusable tools after each use are essential to prevent the spread of bacteria and viruses. Additionally, disposable cleaning supplies can be utilised to further enhance sanitary standards and reduce pathogen spread.

EVS teams use advanced cleaning tools and machinery, such as electrostatic sprayers
Environmental Services (EVS) teams in hospitals are responsible for maintaining the health and safety of the physical environment in a hospital. They actively eliminate harmful pathogens and reduce the risk of healthcare-associated infections (HAIs). EVS teams use a wide variety of tools to improve patient satisfaction, operate efficiently, and keep hospitals clean and safe. These include hardware, software, processes, and actual mechanical tools.
One such mechanical tool that EVS teams use is the electrostatic sprayer. Electrostatic sprayers are advanced tools that have revolutionized how we disinfect surfaces, making the process more efficient, effective, and comprehensive. They work by using an integrated design of air, liquid, and power supply. Air-liquid two-phase atomization technology and secondary induction electrostatic atomization technology break the liquid into small and uniform droplets by using high-pressure airflow to achieve the first crushing and atomization of the liquid. After the first crushing and atomization, the inductive electrostatic spray nozzle will apply an inductive charge to the droplets. After the droplets carry the charge, they will overcome the surface tension of the droplets, achieving a better atomization effect, and ultimately the full and uniform atomization of the droplets.
The small droplets produced by electrostatic sprayers do not wet the object surfaces, avoiding manual cleaning, saving manpower, and avoiding secondary contamination. The strong force of attraction on the droplets will form a 360-degree coverage of the object without any dead ends. This makes electrostatic sprayers ideal for disinfecting hard seating areas, tables, and countertops in cafeterias, classrooms, and other school spaces.
In hospitals, EVS teams use electrostatic sprayers to disinfect patient rooms, operating theaters, and common areas, ensuring that harmful pathogens are eliminated effectively. They are not used in ICUs, operating rooms, or other sterile environments. Electrostatic sprayers have become increasingly common in hospitals and other public areas since the COVID-19 pandemic.
