Safety cabinets

A range of suitable and standardized decontamination protocols exist for the decontamination of different types and makes of safety cabinets including both re-circulatory and ducted biological safety cabinets, utilizing either the Bioquell L2 or Bioquell C hydrogen peroxide vapor generators

Bioquell have many years experience in working with biological safety cabinets and can advise on the fastest and most appropriate methods of decontamination.

Hydrogen peroxide vapor has many advantages over alternative methods such as formaldehyde including its speed, safety and the ability of the lab to stay operational during the cabinet decontamination process.

Hydrogen peroxide vapor is an ideal method for providing a safe and effective method for the decontamination of Biological Safety Cabinets either routinely or prior to servicing or carrying out DOP test on the HEPA filters. Holding the decontamination at negative pressure means that the risk of hydrogen peroxide leakage is minimized thus negating the need to vacate the room during the decontamination process.

FAQs

Will hydrogen peroxide vapor damage my HEPA filters?

Hydrogen peroxide vapor is safe to use with all modern HEPA filters. Mainstream, hydrogen peroxide generators contain HEPA filters that are continually exposed to hydrogen peroxide during the decontamination process with no adverse effect.

Glossary

Re-circulatory BSC’s: Typically the generator’s supply hose is connected to a purpose built connector either permanently fixed to the main chamber wall or via a temporary template taped across the front of the main chamber. The return hose is connected either via a connector off the same template for decontaminating just the main chamber or via a connector taped and sealed into place on the BSC extract grill for a full decontamination of chamber and HEPA filters.
Ducted BSC’s: Typically the generator’s supply hose is connected to either a purpose built connector either permanently fixed to the main chamber wall or via a temporary template taped across the front of the main chamber. The return hose is connected either via connector off the same template for decontaminating just the main chamber or via a purpose built connector permanently installed on the extract duct between the terminal HEPA filter and the damper on the exhaust duct.

A pressure sensor connector is also attached to the Biological Safety Cabinet to allow connection of the generator pressure hose to ensure that the cabinet is kept at negative pressure throughout the decontamination cycle.
