Biosafety level 4 laboratories are designed for diagnostic work and research on easily respiratory-acquired viruses which can often cause severe and/or fatal disease. What follows is a list of select agents that have specific biocontainment requirements according to US federal law.
The Proceedings of a Workshop on "Developing Norms for the Provision of Biological Laboratories in Low-Resource Contexts" provides a list of BSL-3 laboratories in those countries. [ 32 ] Biosafety level 3 is commonly used for research and diagnostic work involving various microbes which can be transmitted by aerosol and/or cause severe disease.
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.
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]
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.

Urushiol is primarily found in the spaces between cells beneath the outer skin of the plant, so the effects are less severe if the plant tissue remains undamaged on contact. Once the oil and resin are thoroughly washed from the skin, the rash is not contagious.
