Study Notes

Laboratories Types

Laboratories are categorized based on their specific functions, purposes, and associated risks.
Each type of laboratory has unique requirements and safety protocols to ensure proper containment and operation.

Analytical and Quality Control (AQC) Laboratories:

AQC laboratories focus on testing products and materials against predefined specifications.
This ensures that products meet quality standards and are fit for their intended purpose.
Data generated in these laboratories is used for decision-making in various fields, such as industry, medicine, and law.
Quality control encompasses the entire process, from sample collection to data reporting.

Biosafety Laboratories:

Biosafety laboratories are designed to contain potentially hazardous biological agents.
These laboratories are classified into four biosafety levels (BSL), ranging from BSL1 (lowest risk) to BSL4 (highest risk).
Each BSL has specific containment controls based on the risk posed by the biological agents handled.

Biosafety Level 1 (BSL1):

Used for work with well-characterized microorganisms that do not cause disease in healthy individuals.
Example: Salmonella bacterium (causes food poisoning).

Biosafety Level 2 (BSL2):

Handles agents that pose a moderate risk to humans and for which effective treatment and preventative measures are available.
Example: Hepatitis A, B, and C viruses, Measles virus
Safety requirements include biohazard markings, controlled waste disposal, protective clothing, and regular decontamination.

Biosafety Level 3 (BSL3):

Handles agents that can cause serious or potentially lethal disease in humans for which treatments exist.
Example: Yersinia pestis (plague), Mycobacterium tuberculosis (tuberculosis)
Safety requirements include specialized hoods with front protection, two sets of self-closing doors, and stringent protocols for decontamination.

Biosafety Level 4 (BSL4):

The highest level of containment, handling agents that cause highly dangerous and often fatal diseases for which there are no effective treatments.
Example: Ebola virus, Lassa fever virus, Coronavirus (in some cases)
Requires a separate, completely enclosed laboratory with multiple safety features, including a specialized cabinet with glove pockets, multiple showers, ultraviolet rooms, and specialized waste disposal procedures.

Clinical and Medical Laboratories:

Perform diagnostic tests on tissue, blood, and other patient samples to aid in diagnosis, treatment, and prevention of disease.
Subdivided into various specialties, including pathology, serology, histology, virology, bacteriology, and molecular biology (with PCR technologies).

Research & Development (R&D) Laboratories:

Encompasses a wide range of laboratories with varying risk qualifications and containment requirements.
Includes biosafety laboratories, laboratories handling radioactive materials, and specialized laboratories for seed, crop, material, and life sciences research.

R&D Activities:

Involve three main categories of research: Basic Research, Applied Research, and Development.

Basic Research:

Aims to deepen understanding of a subject without direct practical or commercial applications.

Applied Research:

Focuses on addressing specific customer or industry needs and requirements.
Aims to develop methods or solutions for practical problems.

Development:

Utilizes research findings to create specific products, materials, systems, and methods.
Includes designing and developing prototypes and processes.
