Biohazards

In September of 2001, a great concern was raised about the threat of biohazards in our world. The possibility that a deadly organism could be deliberately spread throughout a large population became an extremely grave concern. Certain microorganisms, viruses or toxins that originate in biological sources can be spread to both humans and animals, thereby poisoning the food supply and causing widespread harm. As a result of this concern in the wake of the 911 attacks, the biohazard symbol has become widely publicized and a great awareness has been spread to the population.
The biohazard sign is now a common sight in many government facilities and
biohazard signs and biohazard symbols are no longer a thing to be ignored.

In terms of the different signs and the particular biohazard logo that may be found on different facilities, there are four different levels that can now be distinguished. The first of these is the biohazard level one. This sign will indicate the presence of bacteria such as E. coli, canine hepatitis, Bacillus subtilus and varicella or what is commonly known as “chicken pox”. At level one, the biohazards are minimal. A person will mainly need some gloves and a face mask to be protected. A person may also want to wash their hands after being near these biohazards and may want to generally avoid any contact with the receptacles in question.

The second level of biohazard is level two. This level will include the more dangerous exposure to influenza, salmonella, hepatitis B and C and possibly Lyme disease. These are a little more dangerous and may require more adequate protection when entering a facility with these biohazards.

The third level of biohazard is level three and includes exposure to Anthrax, smallpox, Yellow fever, West Nile virus, tuberculosis, SARS, typhus and mumps among others. These biohazards are extremely dangerous and can actually infect thousands of people if they are not adequately contained upon exposure. A person should be very well protected and avoid coming near these facilities unless there is a very important reason to do so.

Finally, a fourth level biohazard is the worst of all biohazards. These include Dengue fever, Bolivian fever, Ebola, hemorrhagic diseases, the Marburg virus, the Lassa virus and the Hanta virus. These are all extremely dangerous and can be spread very easily so they must be avoided at all costs. A biohazard is an extremely serious concern that has now been given a much more active prevention in the wake of the 911 attacks.
