Blood Spills

Blood Spillage is perceived as not being an issue, when dealing with small amounts of blood or bodily fluids in the home. The homeowner normally can handle this without incident, but when dealing with large amounts of blood or bodily fluids it can be dangerous. While thinking that any human or animals bodily fluids in your residence doesn’t harbor any communicable diseases it could be and must be treated as it is an infectious disease per OSHA guidelines 1910.1030. People also never give much thought about the animals in or around their homes. Their blood and bodily fluids can harbor diseases that can affect human beings. Below is some information that just scratches the surface of this topic. Emergi Clean, Inc. can assist you with scenarios dealing with blood or bodily fluids. Please feel free to speak with one of our technicians regarding your situation. We are a phone call away.

Levels of Biohazard

Main article: Biosafety level

The United States Centers for Disease Control and Prevention (CDC) categorizes various diseases in levels of biohazard, Level 1 being minimum risk and Level 4 being extreme risk. Laboratories and other facilities are categorized as BSL (Biosafety Level) 1-4 or as P1 through P4 for short (Pathogen or Protection Level).

Biohazard Level 1: Bacteria and viruses including Bacillus subtilis, canine hepatitis, Escherichia coli, varicella (chicken pox), as well as some cell cultures and non-infectious bacteria. At this level precautions against the biohazardous materials in question are minimal, most likely involving gloves and some sort of facial protection.

Biohazard Level 2: Bacteria and viruses that cause only mild disease to humans, or are difficult to contract via aerosol in a lab setting, such as hepatitis A, B, and C, some influenza A strains, Lyme disease, salmonella, mumps, measles, scrapie, dengue fever, HIV. “Routine diagnostic work with clinical specimens can be done safely at Biosafety Level 2, using Biosafety Level 2 practices and procedures. Research work (including co-cultivation, virus replication studies, or manipulations involving concentrated virus) can be done in a BSL-2 (P2) facility, using BSL-3 practices and procedures.

Biohazard Level 3: Bacteria and viruses that can cause severe to fatal disease in humans, but for which vaccines or other treatments exist, such as anthrax, West Nile virus, Venezuelan equine encephalitis, SARS virus, MERS coronavirus, hantaviruses, tuberculosis, typhus, Rift Valley fever, Rocky Mountain spotted fever, yellow fever, and malaria. Among parasites Plasmodium falciparum, which causes Malaria, and Trypanosoma cruzi, which causes trypanosomiasis, also come under this level.

Biohazard Level 4: Viruses and bacteria that cause severe to fatal disease in humans, and for which vaccines or other treatments are not available, such as Bolivian and Argentine hemorrhagic fevers, Marburg virus, Ebola virus, Lassa fever virus, Crimean–Congo hemorrhagic fever, and other hemorrhagic diseases and rishibola. Variola virus (smallpox) is an agent that is worked with at BSL-4 despite the existence of a vaccine, as it has been eradicated. When dealing with biological hazards at this level the use of a positive pressure personnel suit, with a segregated air supply, is mandatory. The entrance and exit of a Level Four biolab will contain multiple showers, a vacuum room, an ultraviolet light room, autonomous detection system, and other safety precautions designed to destroy all traces of the biohazard. Multiple airlocks are employed and are electronically secured to prevent both doors opening at the same time. All air and water service going to and coming from a Biosafety Level 4 (P4) lab will undergo similar decontamination procedures to eliminate the possibility of an accidental release.


Your blood is living tissue made up of liquid and solids. The liquid part, called plasma, is made of water, salts, and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells, and platelets.

Blood disorders affect one or more parts of the blood and prevent your blood from doing its job. They can be acute or chronic. Many blood disorders are inherited. Other causes include other diseases, side effects of medicines, and a lack of certain nutrients in your diet.

Types of blood disorders include

• Platelet disorders, excessive clotting, and bleeding problems, which affect how your blood clots

• Anemia, which happens when your blood does not carry enough oxygen to the rest of your body

• Cancers of the blood, such as leukemia and melanoma

• Eosinophilic disorders, which are problems with one type of white blood

Blood Safety


How long do bacteria and viruses live outside the body.
It depends on the type of bacteria or virus and what kind of surface they are on. Most bacteria, viruses, and fungi that cause diseases need moisture to survive so the moisture in the air and in surfaces can also affect how long they live outside the body.
