What are BSL-2 organisms?
Examples of BSL-2 organisms are: Mycobacterium, Streptococcus pneumonia, Salmonella choleraesuis. BSL-3 risk group contains biological agents that usually cause serious disease (human, animal or plant) or that can result in serious economic consequences. These agents are usually not spread by casual contact.
What is a Class 2 pathogen?
Human pathogens – Class of risk 2 : micro-organisms that can cause human disease and might be a hazard for directly exposed persons; they are unlikely to spread to the community. They may present a high risk of spreading to the community. There is usually no effective prophylaxis or treatment available.
What is biosafety level 3?
In a BSL-3 lab, all experiments are conducted in a biosafety cabinet to avoid exposure in the case of spills. Since these labs deal with infectious agents that may be transmitted through the air, ventilation inside a BSL-3 lab is controlled via a filtered ventilation system.
What is the difference between BSL-1 and BSL 2?
The main difference in the work procedures followed in a BSL-1 laboratory and a BSL-2 laboratory is that employees in a BSL-2 laboratory will use a BSC as a primary barrier for potentially hazardous aerosols. Access to BSL-2 laboratories must be restricted.
What’s the difference between Biosafety Level 1 and 2?
Biosafety Level 2 (BSL 2) is similar to Biosafety Level 1 and is suitable for work in clinical, diagnostic, teaching,research or production facilities involving agents of moderate potential hazard to personnel and the environment. It differs in that;
Where can I find biosafety levels for biological agents?
Stanford University follows the categorizing of infectious agents into levels as described in Biosafety in Microbiological and Biomedical Laboratories (BMBL), 5th edition, written and published by the Centers for Disease Control (CDC) and NIH.
What are the classes in the Biosafety manual?
A. Class 1 Agents of no or minimal hazard under ordinary conditions of handling at Biosafety Level 1. B. Class 2 Agents of ordinary potential hazard.
What are the biosafety levels of recombinant DNA?
The descriptions of biosafety levels (BSL) 1 – 4 parallel those in the NIH Guidelines for research involving recombinant DNA. The BSL categories are divided up by risk of disease combined with availability of preventive and therapeutic treatments. The table below contains a list of agents and their categories.
