To appoint a service provider for a period of 12 months for Deep Cleaning Services (as and when required)

RFQ/OBP103/2025/26

To appoint a service provider for deep cleaning services at OBP for a period of not more than one year. This SOP is designed to provide guidance for environmental surface cleaning and disinfection of laboratories and work areas at OBP. Regular disinfection is required in any laboratory handling biohazardous agents. Regular disinfection is also important in other laboratories to reduce the risk of contamination. Reducing risk of contact exposure to infectious agents through routine cleaning and disinfection is an important part of regular laboratory environment maintenance. • Cleaning refers to the removal of dirt and impurities, including germs, from surfaces. Cleaning alone does not kill germs. But by removing the germs, it decreases their number and therefore any risk of spreading infection. Cleaning is achieved with soap and water. • Disinfecting works by using chemicals, for example EPA-registered disinfectants, to kill germs on surfaces. This process does not necessarily clean dirty surfaces or remove germs. But killing germs remaining on a surface after cleaning further reduces any risk of spreading infection. Below is the scope of work the service provider will be required to perform but not limited to points below • Prepare the workplace to facilitate cleaning and disinfection. For example, use plastic keyboard covers for shared computers, and disposable plastic clings over touch screens. • Visibly soiled surfaces must be cleaned prior to disinfection. • Disinfectants have a finite shelf life. Do not use expired disinfectants. • Disinfectants present health and physical hazards. Read and adhere to all precautions and instructions (including proper use concentration) in the manufacturer’s Safety Data Sheet (SDS) and label. • Disinfectant efficacy depends on proper contact time to achieve adequate kill time. This varies between disinfectants. Ensure proper contact time during use. • Pause lab operations in the target area during cleaning/disinfection. • Use damp cleaning methods. Do not clean with dry dusting or sweeping as this may create airborne particles. • Clean from least to most dirty areas. Change mop heads, rags, and similar items frequently during the cleaning/disinfection process. Consider using disposable cleaning items. • Use a double-bucket method when rinsing is necessary (one bucket for cleaning/disinfectant solution, one for rinsing). Some disinfectants are corrosive or otherwise damaging to certain surfaces and will require rinsing after the appropriate contact time has been achieved. • Clean, disinfect, and dry non-disposable equipment at the end of each work shift and when known to be contaminated. When risk of community acquired infection is high, clean and disinfect shared spaces/items after use and before sharing with others. Work surfaces (e.g., biosafety cabinets, lab benches, etc.) and high-touch surfaces should be cleaned and disinfected. Examples include: o Door, appliance, and cabinet handles; o Light switches; o Benchtops; o Desks; o Chairs/seats; o Telephones; o Computers, screens, keyboards, and other analytical equipment (e.g., centrifuge lids, biosafety cabinets, fume hoods, incubators, etc.); o Reagent and other containers, pipettors, and other shared equipment/devices o Hand-washing sinks and handles. DISINFECTION Use all disinfectants according to manufacturer’s instructions. Proper disinfection procedure should include: • Recommended dilution of disinfectant; • Liberal application with clean cloth, sponge, or hand mop; • Sufficient surface contact time as indicated by manufacturer; • Allow to air dry.
