Fully geared with a complete swab kit and safety gloves, Initial Hygiene Specialist, Sandy is ready to assume the role of a “science investigator” with a Lumitester measuring instrument to test for bacteria and germs evidence.
The Structured Hygiene Survey (SHS) is an important milestone for her client. The office houses more than 100 employees, this means regular and frequent interaction could potentially risk cross contamination among each other. So what do bacteria and germs look like and where are they? The SHS helps to answer.
Today, Sandy will help to shed some light on bacteria count in common areas, let’s move on to find out!
The washroom main door handle is a high usage and common touchpoint. Sandy whips out the kit’s swab stick, wets the bud tip and starts on the door handle by swabbing across the surface. The stick returns into the kit and the operation is completed with the push-in swab and mix with the reagent. To take the reading of bacteria count per square inch (BPSI), the entire swab kit is then inserted into the Lumitester measuring instrument. Find out the results below:
(A reading more than 200 BPSI indicates bacteria build-up and surface contamination.)
- Washroom main door handle @ 313 BPSI
- Toilet seat cover @376 BPSI
- Toilet cubicle door knob @ 502 BPSI
- Toilet flush button/ handle @ 729 BPSI
