Choosing the Right Disinfectant: A Guide for EVS Professionals
Choosing the right disinfectant is a critical decision for environmental services (EVS) professionals, impacting patient safety and infection control. Selection involves understanding microbial targets, proper application practices, chemical properties, and regulatory compliance.
• Identify microbial targets: Different disinfectants are effective against specific pathogens, such as C. difficile requiring sporicidal agents, Candida auris needing specialized claims, and viruses like SARS-CoV-2 covered under EPA List N. Knowing these targets ensures appropriate product choice.
• Adhere to contact time: Disinfectants must remain visibly wet on surfaces for the full labeled contact time, which can vary from 30 seconds to 10 minutes. Compliance is often low, so choosing products with shorter validated contact times and training staff on wet dwell time is essential.
• Understand disinfectant chemistry and compatibility: Active ingredients like quaternary ammonium compounds, accelerated hydrogen peroxide, sodium hypochlorite, and phenolics have distinct efficacy and safety profiles. Verifying EPA registration for targeted pathogens and ensuring surface compatibility prevents damage and maintains cleaning effectiveness.
