      Terminal Cleaning of the Operating Room

      ByJohn Weir January 5, 2026January 4, 2026

      When you think of the word “clean,” you might picture a sparkling kitchen counter. But in a hospital operating room, “clean” is a term of microscopic precision, where the stakes are infinitely higher. For the highly trained Environmental Services (EVS) technicians responsible for this environment, cleaning is not about tidiness—it is a critical, non-negotiable component of patient safety.

      Confronting the Ghost in the Room: Why Candida auris Demands Aggressive Disinfection

      ByJohn Weir January 4, 2026January 3, 2026

      Analogy for Understanding: Think of Candida auris like a “microscopic ghost.” Long after a patient has been discharged, the fungus remains haunting the surfaces of the room. Using standard cleaners is like dusting the furniture while the ghost remains; only periodic interventions like this will truly clear the space for the next patient.

      6 Microbial Secrets That Will Change How You See the World

      ByJohn Weir January 3, 2026January 3, 2026

      Microbes are everywhere—on your skin, in the air you breathe, and in the food you eat. They form a vast, invisible universe that shapes our lives in profound ways. While we often think of “germs” as simple enemies to be defeated, their stories are far more complex, surprising, and fascinating than we can imagine. From their discovery and evolution to their impact on our health, the interplay between microbes and humanity is a journey through the quirks and mysteries of life at the microscopic level.

      Housekeeping in Washington State Behavioral Health Facilities: A Historical and Safety-Oriented Perspective

      ByJohn Weir May 24, 2025May 24, 2025

      Washington’s state hospitals grew rapidly between the 1920s and 1940s. By 1930, Western and Eastern State Hospitals housed thousands of patients, many of whom lived in appalling conditions. Despite the increased scale, there was no corresponding improvement in cleaning practices or worker protections. Institutional housekeeping remained a custodial function assigned to patients or underpaid staff without training.

      Cleaning methods focused on visible tidiness rather than microbial safety. Chemical use was unregulated, and tools were rudimentary. Staff and patients were exposed to pathogens, toxic substances, and unsafe physical environments. There were no systems for reporting workplace injuries or exposures. Institutional goals prioritized containment over care, and the human dignity of workers and residents was largely ignored.

      ByJohn Weir March 3, 2025March 3, 2025

      As Environmental Services (EVS) professionals, we play a crucial role in healthcare beyond just cleaning rooms and disinfecting surfaces. We are often the first and last hospital staff members a patient sees each day, and the way we carry ourselves can significantly impact their experience. A clean room provides comfort, but a kind interaction can bring true peace of mind.
