Biohazard Safety Cabinets
Although it has only been a few days since the discovery of the new Covid-19 variant, everyone is talking about it, asking questions, and wondering if it’s a cause for serious concern. Various countries have responded by closing their borders to most Southern Africa countries in a desperate attempt to contain the spread of the new variant.

The standard safety protocol for the manipulation of chemotherapy drugs in oncology clinics and laboratories involves the use of a bio-safety cabinet (BSC), which tend to be Class II, either Type A or B. These have High Efficiency Particulate Air (HEPA) filters and may be exhausted outside. As long as the BSC is well maintained and functioning correctly, it provides personnel with a strong measure of protection against accidental exposure to the drugs, particularly in aerosol form; but the BSC alone is not sufficient and extra precautions are necessary. Correct and consistent use of Personal Protective Equipment (PPE) is vital.
Vivid Air uses the latest decontamination kits available, these boil off the correct amount of formaldehyde after a delay timer has been set to allow all personnel to vacate the immediate area around the cabinet as well as a time delay neutralization phase using ammonia to neutralize the reside formaldehyde in the cabinet before the technicians break the seal to commence their service or validation of the BSC.
BSCs provide safe, enclosed spaces for working with contaminants. These essential features of laboratories can typically be used for 15-25 years, but they do suffer wear and tear, and eventually need replacing.
Class II Biohazard Safety Cabinets are essential in handling COVID-19 samples in the laboratory
While the world is facing unprecedented challenges with the Coronavirus 2019 pandemic (COVID-19) we at Vivid Air will continue to play a critical role.
To compensate for system pressure fluctuations, constant Volume (CV) fans maintain a set output. This is beneficial to maintaining installation design parameters for HVAC and cleanroom applications.
In this article, Vivid Air explains the benefits of installing CV fans, in particular the Direct Driven Centrifugal Fan.
The Heating, Ventilation and Air Conditioning (HVAC) industry looks set to experience robust growth over the next six years in response to increasing demand. At the same time, the industry faces various changes and challenges. Keeping up to date on the status of, and trends and transformations in, the HVAC industry is not only important for building owners and operators, but anyone in charge of HVAC equipment.
Bio-safety Cabinets are divided into three broad classes – called I, II and III – based, among other things, on the level of protection they provide. This article explores features and functionalities that are unique to each of the classes, highlighting the key differences between them.
