Difference Between a Controlled Environment and a Cleanroom
What’s a controlled environment?

A controlled environment, or critical environment, is an area that must have certain parameters controlled, specifically, pressure, temperature, and segregation. Many laboratories are considered controlled environments, as they have controlled temperature and pressure and are separated from other operations, such as manufacturing or shipping. Unlike cleanrooms, controlled environments do not necessarily have to meet certain standards for particle contamination.

What’s a cleanroom?

A cleanroom is a type of controlled environment, but one with much more stringent requirements. Cleanrooms require temperature and pressure control, as well as separation from the outside environment and other operations, but these things must be controlled to specific standards. Cleanrooms are classified by the maximum acceptable numbers of particles (by size) in the air per cubic meter, and must be regularly tested to ensure compliance to that standard (see more about cleanroom classifications here). Compared with other controlled environments, cleanrooms may require more energy, air, and advanced technology to maintain the cleanroom conditions.

Centers for Disease Control and Prevention.
CDC works 24/7 to protect America from health, safety and security threats, both foreign and in the U.S. Whether diseases start at home or abroad, are chronic or acute, curable or preventable, human error or deliberate attack, CDC fights disease and supports communities and citizens to do the same.

CDC Guideline for Disinfection and Sterilization in Healthcare Facilities

The Centers for Disease Control and Prevention (CDC) sets BSL lab levels as a way of exhibiting specific controls for the containment of microbes and biological agents.
Biosafety Levels
Biosafety Levels (BSL) prescribe procedures and levels of containment for the particular microorganism or material.

International Air Transport Association Serving the airline industry. We help airlines to operate safely, securely, efficiently, and economically under clearly defined rules. Professional support is provided to all industry stakeholders with a wide range of products and expert services.

Laboratory Biosafety level 1 (BSL-1)
As the lowest of the four, biosafety level 1 applies to laboratory settings in which personnel work with low-risk microbes that pose little to no threat of infection in healthy adults.

Examples of typical BSL-1 biological material:
Bacteria: Agrobacterium tumefaciens, Escherichia coli K-12, Pseudomonas fluorescens, Bacillus subtilis
Viruses: canine adenovirus types 1 and 2, Bovine enterovirus
Fungi: Saccharomyces cerevisiae
Certain cell cultures: Endoparasites of animals and humans (e.g., some nematodes)

Laboratory Biosafety level 2 (BSL-2)
This biosafety level covers laboratories that work with agents associated with human diseases (i.e. pathogenic or infections organisms) that pose a moderate health hazard.

Examples of typical BSL-2 biological material:

Bacteria: Chlamydia pneumoniae, Enterobacter spp., Mycoplasma pneumonia, Yersinia pseudotuberculosis

Viruses: Herpes simplex virus, HIV (when performing routine diagnostic procedures or working with clinical specimens

Laboratory Biosafety level 3 (BSL-3)
SL-3 laboratory typically includes work on microbes that are either indigenous or exotic, and can cause serious or potentially lethal disease through inhalation.
Examples of typical BSL-3 biological material:
Bacteria: Yersinia pestis, Brucella abortus, Chlamydia psittaci, Pseudomonas mallei
Viruses: West Nile fever, herpes B, hepatitis A

Laboratory Biosafety level 4 (BSL-4)
As the highest level of biological safety, a BSL-4 lab consists of work with highly dangerous and exotic microbes. Infections caused by these types of microbes are frequently fatal, and come without treatment or vaccines.
Examples of typical BSL-4 biological material:
Ebola-Virus, Lassa-Virus, Marburg-Virus

A preventive control plan (PCP) is a written document that demonstrates how hazards to your food are identified and prevented, eliminated or reduced to an acceptable level.
