Cleaning the BSC
• Clean the work surface and walls with appropriate disinfectant and soap water afterward.
• Clean the sash window with appropriate disinfectant and glass cleaner afterward.
• Use a damp cloth to clean the exterior surface of the BSC, particularly on the front and top in order to
remove dust that has accumulated there.
• Use sterile water to finish the cleaning and wash away any residue of disinfectant, soap, water and
glass cleaner.
• For removing stubborn stains or spots on the stainless steel surface, make use of MEK (Methyl-Ethyl-
Ketone). In such cases, make sure that you wash the steel surface immediately afterwards with sterile
water and some liquid detergent. Use a polyurethane cloth or sponge for washing. Regular cleaning of
the stainless steel surface helps retain the attractive factory finish.
• Ensure that the chemicals used are compatible with one another.
• Use appropriate personal protective equipment (PPE) when carrying out the activity.
Test the audible and visual alarm
The simplest method by far would be to move the sash until the glass window is no longer in the sash ready or
UV mode position.
Check the cabinet’s functionality
• Check the BSC’s mechanical functionality (e.g. sash window – lubricate if necessary).
• Check the BSC’s electrical functionality (e.g. fluorescent lamp – replace if necessary).
• Check the BSC for any defect and if any, repair immediately.
Recertification
All BSCs must be re-certified annually by a certified engineer. See certification procedures attached to the
factory test report.
