Biohazards: Types, Classifications, and Cleanup Procedures

“Biohazard” is one of the few terms that causes as much anxiety because it makes people think of hazmat suits, hazard tape, condemned property, and a lot of money. What are biohazards, and how should you react if you need to deal with a biohazard cleanup?

Whatever poses possible harm to health, such as chemicals, blood, or body fluids, is referred to as a biohazard. Biohazards need to be cleaned up correctly since they endanger your family. The best action in this situation is to contact a biohazard cleanup company.

Types of Biohazards

Contrary to popular belief, biohazards can often be found in residential and commercial structures. While some are uncommon in regular homes or offices, others are unexpectedly common.

  • Animal carcasses and droppings– Pests that spread disease, including flies and rats, are drawn to corpses. Droppings may include airborne germs and viruses.
  • Human bodily fluids– Bodily fluids, such as blood, saliva, amniotic fluid, and others, can spread infections.
  • Medical waste– Comprises surgical and autopsy waste, laboratory cultures, and tissue samples.
  • Mold and fungi– Spores can spread through the air and cause respiratory, neurological, and other conditions.
  • Viruses and bacteria– Some bacteria and viruses may survive without hosts and provide a risk to anybody accessing the environment.

Biohazards Classifications

The CDC further divides biohazards into groups according to the potential harm they pose:

  • Level 1– pose a minor hazard to humans (ex.: mold and mildew)
  • Level 2– cause moderate harm to humans (ex.: HIV)
  • Level 3– high-risk pathogens that can become airborne (ex.: COVID-19)
  • Level 4– life-threatening pathogens with no known treatment (ex.: Ebola)
