Routine Fumigation

According to BS EN 12469:2000 and the Advisory Committee on Dangerous Pathogens (ACDP), Microbiological Safety Cabinets (MSC) should be fumigated:

  • Before any work on the safety cabinet where access to potentially contaminated parts is necessary, including pre filter and main filter changes
  • Before undertaking in situ HEPA filter leak integrity testing
  • After a spillage where inaccessible surfaces may have become contaminated
  • Before maintenance engineers are permitted to work on the equipment.

Crowthorne now offer Equipment Bio-Decontamination Service (EBDS) specifically designed to fumigate microbiological safety cabinets, incubators, robotic enclosures and similar laboratory equipment.

Where there are a number of safety cabinets to service, we perform an overlapping fumigation and service schedule to drastically reduce laboratory downtime.

Emergency Fumigation

Emergency fumigation can also be arranged under a regular schedule contract or ad-hoc dependant on the requirements of your facility.

Formaldehyde vs. Hydrogen Peroxide Fumigation

Whilst hydrogen peroxide fumigation has been proven to be a safe and efficient method of fumigation, many users prefer to stick with the ‘tried and tested’ solution of formaldehyde decontamination for its highly reliable and effective results, its broad antimicrobial efficacy and its log reduction.

As formaldehyde requires a lengthy contact time, fumigation is generally run overnight. Your engineer will return to site the next morning to complete the fumigation process, making sure the safety cabinet is fully decontaminated and ready for use, ensuring minimal disruption and downtime of the safety cabinet.
