Explanation:

A Biological Containment is related to laboratory biosafety. In order to ensure a safe and secure environment for both workers and the bacteria, the lab must be sealed and the bacteria sealed, isolated and/or secure.

Bacteria is a Biological Containment because if it is not secured and kept away properly, there is a great risk of the Bacteria getting out and spreading. Depending on what type of bacteria it is, if it spreads and the bacteria is deadly, the result could end in harm or death. That is why making sure bacteria is secure is vital when working in a laboratory or around it.

Fingernails, hair, ammonias and insect parts do not need to be kept isolated and contained. They do not result in fatal death. Yes, they can catch or grow mold such as bacteria or such, but otherwise they are safe.
