What are some characteristics of a BSL-3 lab?

What are some characteristics of a BSL-3 lab?

However, the common essential features of BSL-3 laboratory include unidirectional air flow using room pressure gradients of negative pressure, exhaust air being HEPA (high efficiency particulate air) filtered and proper procedures for disposal of biomedical waste.

What is a BSL-3 lab?

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.

Which of the following elements must be a component of the BSL-3 laboratory design?

The laboratory must consist of an anteroom and laboratory rooms. The facility must have gas-impermeable walls, ceilings, and floors. Air gaps under doors are acceptable for directional airflow.

How many BSL-3 labs are in the UK?

600 laboratories
There are approximately 600 laboratories around the UK that are built to operate at BSL-3.

How does a BSL-3 lab work?

BSL-3

  1. Standard personal protective equipment must be worn, and respirators might be required.
  2. Solid-front wraparound gowns, scrub suits or coveralls are often required.
  3. All work with microbes must be performed within an appropriate BSC.
  4. Access hands-free sink and eyewash are available near the exit.

What is the main differences between a BSL 1 and a BSL 2 lab?

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.

How many BSL-4 labs are there?

There are currently only four operational BSL-4 laboratory suites in the United States: at the Centers for Disease Control and Prevention in Atlanta; at the United States Army Medical Research Institute for Infectious Diseases at Fort Detrick in Frederick, Maryland; at the Southwest Foundation for Biomedical Research …

What is a containment level 2 laboratory?

Containment level 2 (CL 2) is used for work with medium risk biological agents and hazards, genetically modified organisms, animals and plants.

What are the 2.03 BSL3 design guidelines?

2.03 –BSL3 Design Guidelines Introduction and Basis of Design: The following BSL-3 Design Guidelines are intended to assist the Washington University School of Medicine (WUSM) and its stakeholders with programming and design of new Biosafety Level 3 (BSL-3) and Animal Biosafety Level 3 (ABSL-3) facilities.

What are the requirements for a BSL-3 laboratory?

The facility must pass third-party inspection and tests to verify that design and operational parameters have been met. This should be done by a third party. The laboratory must be located away from public areas and corridors used by laboratory personnel who do not work in the BSL-3 laboratory.

How tall should the ceiling be in a BSL-3 lab?

Ceiling height should be at least 10 feet to allow for 14 inches of clearance above BSCs. Light fixtures must be surface or independently mounted. If recessed lighting must be used because of ceiling height in a renovation, lighting penetrations are gasketed. Eating and drinking is prohibited in BSL-3 laboratories.

What is the biosafety cabinet in BSL-3?

The biosafety cabinet is relied upon as the primary device in BSL-3 laboratories for protecting prod- ucts, personnel or the environment. Contrast this with chemical fume hoods designed to provide only personnel protection. The pressurized lab space serves as a secondary containment barrier.
