Biosafety Level 3 (BSL-3) BSL-3 laboratories are used to study infectious agents or toxins that may be transmitted through the air and cause potentially lethal infections. Researchers perform all experiments in a biosafety cabinet. BSL-3 laboratories are designed to be easily decontaminated..
What is hospital biosafety?
For hospitals, bio- safety is the application of knowledge, techniques, and equipment to prevent personal, laboratory, and environmen- tal exposure to potentially infectious agents or biohazards (Coelho, 2012; St\xf6ppler, 2020)..
What is the most common risk to healthcare workers?
Occupational infections. The most common occupational infections of concern in the health sector are tuberculosis, hepatitis B and C, HIV/AIDS and respiratory infections (coronaviruses, influenza).Unsafe patient handling. Exposure to hazardous chemicals..
Why is biosafety important in our daily life?
The goal of biosafety is to reduce or eliminate exposure of lab personnel, the community and the environment to potentially infectious or hazardous agents and this is achieved via the principles of containment and risk assessment..
For hospitals, bio- safety is the application of knowledge, techniques, and equipment to prevent personal, laboratory, and environmen- tal exposure to potentially infectious agents or biohazards (Coelho, 2012; St\xf6ppler, 2020).
The BSO develops biological safety resources, educational material, fact sheets, and white papers for university, college, department and/or community research activities, performs laboratory inspections, develops/presents training in accordance with the requirements of WVU policy and federal and state regulations, and
Anatomic Pathology
The practice of anatomic pathology plays a critical role in determining accurate disease diagnoses by studying organ tissues and fluids. Anatomic pathology includes surgical pathology, histotechnology, cytology, and autopsy.
Decentralized and Point-of-Care Testing
Point-of-Care (POC) tests are intended to supplement laboratory testing or extend testing to communities and populations that cannot readily access laboratory testing. In addition, POC testing helps address emerging outbreaks quickly.
Environmental Testing
This guidance for environmental testing is intended only for laboratories that perform virus concentration as part of the wastewater/sewage surveillance testing procedure. This guidance does not include public health or clinical diagnostic laboratories that handle SARS-CoV-2 clinical specimens or BSL-3 laboratories that perform culture and isolation of SARS-CoV-2. Site- and activity-specific biosafety risk assessments should be performed to determine if additional biosafety precautions are needed based on situational activities, such as high testing volumes, and the likelihood of generating infectious droplets and aerosols.
General Guidance
All laboratories should perform a site-specific and activity-specific risk assessment to identify and mitigate risks. Risk assessments and mitigation measures are dependent on:
Key Points
•This guidance is intended for clinical laboratory and support staff who handle or process specimens associated with COVID-19. For guidance on point-of-rare testing, see the Guidance for SARS-CoV-2 Point-of-Care and Rapid Testing
Routine Diagnostic Testing
Routine diagnostic testing procedures, such as the following activities, can be handled in a BSL-2 laboratory using Standard Precautions:
