Disinfection Service — Private Medical Clinic, i-City

Disinfection Service — Medical Clinic, i-City Case Study

The clinic manager contacted Mr Pest Control Shah Alam after receiving a reminder from their private practice consultant to update their premises disinfection records. Located in the commercial belt of i-City, the clinic sees a steady flow of patients daily across general practice and minor procedure consultations.

The Problem

Medical clinics are among the highest-risk environments for cross-contamination and the spread of airborne and surface-borne pathogens. Even with daily cleaning by clinic staff, there are areas that standard mopping and surface wiping cannot adequately reach — ceiling vents, the underside of chairs and counters, curtain rails around consultation beds, and corners of storage rooms.

The clinic's specific concerns at the time of contact were:

• High patient footfall throughout the week with no dedicated disinfection service in the past six months
• Waiting area chairs and registration counter identified as high-touch, high-risk zones
• Two consultation rooms and one procedure room requiring full sanitisation
• Staff pantry and rest area included in the scope at the clinic manager's request
• Management required a disinfection certificate for their practice compliance records

The clinic had previously relied solely on daily surface cleaning by the clinic assistant, which is insufficient as a standalone measure for a medical premises. A professional disinfection service using ULV fogging and hospital-grade chemicals was recommended to address all zones comprehensively.

Our Approach

We scheduled the treatment for after the clinic's closing time at 9:00 PM to ensure no disruption to patient appointments and to allow sufficient contact time before the clinic reopened the following morning. Our team arrived with full PPE, a ULV fogging machine, and hospital-grade disinfectant solution.

The treatment scope was agreed with the clinic manager prior to arrival and included all patient-facing areas as well as back-of-house staff zones. A detailed checklist was completed room by room and signed off upon completion.

The Treatment

The disinfection process was carried out systematically from the back of the premises to the front exit, ensuring no treated areas were re-entered before drying was complete:

1. Pre-treatment preparation: All exposed food, medications, and sensitive equipment were covered as instructed. Clinic staff cleared the premises and locked away patient records.
2. ULV fogging — all rooms: ULV (ultra-low volume) fogging was carried out in all rooms including the waiting area, registration counter area, two consultation rooms, procedure room, toilet, and staff pantry. The ULV machine produces a fine mist of disinfectant particles that remain suspended in the air for several minutes, reaching all surfaces including ceiling vents, under furniture, and air circulation points.
3. High-touch surface wipe-down: After fogging, all high-touch surfaces were manually wiped using hospital-grade disinfectant solution. This included door handles and push plates, registration counter surface, chair armrests in the waiting area, examination bed rails, light switches, and the toilet flush and tap handles.
4. Staff areas: The staff pantry and rest area were fogged and wiped separately, with particular attention to the microwave handle, kettle, and communal table surface.
5. Disinfection certificate: Upon completion, we issued a disinfection certificate documenting the date, scope, chemicals used, and our company registration details for the clinic's compliance file.

Results

The treatment was completed within 3 hours, well before midnight, allowing sufficient drying time before the clinic reopened the following morning at 8:30 AM. The clinic manager reported that the premises smelled clean and fresh upon reopening, with no chemical residue on surfaces.

The disinfection certificate was accepted by the clinic's private practice consultant and filed into their compliance documentation. The clinic subsequently arranged for quarterly disinfection treatments to maintain ongoing hygiene standards throughout the year.

For medical clinics, we recommend a minimum of quarterly disinfection — or monthly during periods of elevated respiratory illness in the community. Regular disinfection not only protects patients and staff but also demonstrates a commitment to clinical hygiene standards that builds patient confidence.

"Very professional service. The team arrived on time, worked quietly and efficiently after hours, and provided the certificate we needed for our records. We have since arranged quarterly bookings."
