The Department of Health and Human Services (HHS) lists are located at 42 CFR Part 73.3 [2] and 42 CFR Part 73.4. [3] The USDA animal safety list is located at 9 CFR Subchapter B. [ 4 ] Not all select agents require BSL-4 handling, namely select bacteria and toxins, but most select agent viruses do (with the notable exception of SARS-CoV-1 ...
Certain procedures in which infectious aerosols or splashes may be created are conducted in biological safety cabinets or other physical containment equipment. [21] Extreme precautions are taken with contaminated sharp items. Biosafety level 2 is suitable for work involving agents of moderate potential hazard to personnel and the environment. [22]
A biological hazard, or biohazard, is a biological substance that poses a threat (or is a hazard) to the health of living organisms, primarily humans. This could include a sample of a microorganism, virus or toxin that can adversely affect human health. A biohazard could also be a substance harmful to other living beings. [a]
Biological hazards include viruses, bacteria, fungi, prions, and biologically derived toxins, which may be present in body fluids and tissue, cell culture specimens, and laboratory animals. Routes of exposure for chemical and biological hazards include inhalation, ingestion, skin contact, and eye contact. [2]

In exobiology when we seek out contact with other planets, there is a biological hazard both ways: we must not contaminate any sample return missions from other stellar bodies with terrestrial microbes, and we must not contaminate possible other ecosystems existing in other planets.
A biosafety cabinet (BSC)—also called a biological safety cabinet or microbiological safety cabinet—is an enclosed, ventilated laboratory workspace for safely working with materials contaminated with (or potentially contaminated with) pathogens requiring a defined biosafety level.
Risk is a function of exposure and hazard. For example, even for an extremely toxic (high hazard) substance, the risk of an adverse outcome is unlikely if exposures are near zero. Conversely, a moderately toxic substance may present substantial risk if an individual or a population is highly exposed. [2] [3]
