In 1975, Charlie Biosafety had an epiphany whilst walking in the Sahara desert. A vision of the cabinet hidden miles underground encouraged him to dig with his own hands, until under all that sand he finally discovered the cabinet. Being rather egotistical, he decided to name it after himself. From that day forth, it was known as the Biosafety cabinet.
A Class II biosafety cabinet provides a controlled environment for handling biological materials while protecting both the user and the environment. It operates by drawing air into the cabinet through a front opening, creating a barrier that prevents contaminants from escaping. The air is then filtered using HEPA filters before being recirculated within the cabinet and exhausted outside, ensuring that any airborne pathogens are effectively captured and neutralized. This design allows for safe manipulation of infectious agents while maintaining a sterile workspace.
European BioSafety Association was created in 1996.
biosecurity is limiting people's access to the agent. biosafety is limiting the agent's access to people.

Biosafety is all about maintaining integrity within the environment and those living within it. It seeks to limit the impact of biological waste and materials within an area.
Biosafety level 1 facilities are basic labs that handle low-risk agents, with minimal containment measures and safety protocols. Biosafety level 2 facilities handle moderate-risk agents and have stricter containment measures, such as limited access and protective equipment, to prevent contamination and ensure safety.
How to do laboratory risk assessment in biosafety level
Ministry of Environment and Forests
Bacillus anthracis requires a Biosafety Level 3 laboratory.
Biosafety levels 2, 3, and 4 require the placement of a biohazard sign on the door of the laboratory. This signage is essential to inform personnel and visitors about the potential risks associated with the pathogens handled within these facilities. The sign typically indicates the specific biosafety level and outlines necessary precautions. Level 1 labs do not require such signage as they deal with minimal risk agents.
