Biologically hazardous materials should be kept under strict control at all times in order to safeguard the public's health? Most often called "biohazards," these materials are substances or organisms which may be harmful to people or animals when unintended exposure occurs.
They are most often connected with the medical field since they generally include medical waste as well as biologically sourced samples of a virus or toxin. If you are not in the medical profession, then no, you probably are not at high risk of coming into contact with biohazardous materials. The most common way that people become infected through contact with biohazards is through the spillage of fluids. Here are some of the classifications of biohazardous materials:
-- Level 1: These are the most innocuous of all biohazards in that they present the lowest risk of serious injury should contamination occur. They are still hazardous, however, but the precautions against contamination are minimal: rubber gloves, protective eyewear, and a lab coat. The biohazards in this category may include chicken pox, non-infectious bacteria, and other organisms that may cause symptoms similar to food poisoning in humans.
-- Level 2: The potential harm to humans is greater for these biohazards than those categorized in level 1, but they are still relatively mild or may cause diseases that are difficult to contract without contact with human fluids or nasally. Those that fall into this category include many of the viruses that have been virtually eradicated in the western world thanks to childhood vaccines: mumps, measles, the three most common forms of Hepatitis, HIV, salmonella, and influenza. In lab settings, more rigorous precautions are taken to safeguard against accidental contamination.
-- Level 3: These bacteria and viruses may cause serious damage or even death in humans, but are treatable with modern medicines and therefore offer hope for a cure. Some familiar names in this category include West Nile virus, tuberculosis, SARS, typhus, and malaria. When work needs to be done with these agents, it is done in a room with no air recirculation and where the worker is wearing full protective gear. Any kind of work that may create aerosols or splatters of any type must be done within a biological safety cabinet to further safeguard against contamination.
-- Level 4: Contamination by these hazards is not dangerous to humans, but there is also no known cure once infection occurs. So it can safely be said that these biohazards are, indeed, fatal. Ebola, Hantavirus, bird flu, and various types of exotic flus and fevers all may be classified under level 4. Working with these substances requires the wearing of a full Hazmat suit and the lab must be equipped with multiple layers of infection preventative equipment.
Obviously, most lay people will never be exposed to these biohazards due to accidental spillage, but lab workers are always at greater risk. Any kind of biohazardous spill should be handled only by professionals who are trained in the proper methods to dispose of the materials safely and efficiently.
