Is Vomit Biohazard Waste

A biological hazard, or biohazard, is a biological substance that poses a threat to the health of living organisms, primarily humans. This could include a sample of a microorganism, virus, or toxin that can adversely affect human health. A biohazard could also be a substance harmful to other animals.

The Centers for Disease Control identifies four levels of biohazard waste:


  • Biohazard Level I: any agent that has the potential to pose even minimal threats to humans or the environment. A prime example is E. coli.
  • Biohazard Level II: an agent that may cause severe illness in a human such as one that is transmitted through direct contact with infected materials. Primary examples of this level include hepatitis B, HIV, or Salmonella.
  • Biohazard Level III: any pathogen that has the potential to become airborne and cause severe illness or disease. An example of this level of biohazard includes tuberculosis.
  • Biohazard Level IV: a pathogen that has an extremely high risk of producing life-threatening disease for which there is no treatment. One of the most well-known today includes the Ebola virus.

Is Vomit Biohazard Waste?

In the strictest sense, vomit without blood is NOT considered or regulated as biohazard waste. In addition, the following are NOT also regulated as biohazardous waste unless contaminated with blood:

  • Urine
  • Feces, Stool
  • Nasal Secretions


All of the unregulated substances can be discarded in the regular trash


The following are considered biohazardous waste:


  • Blood
  • Clothing or Linens Contaminated With Blood
  • Any Body Fluid Where Blood is Visible
  • Any Body Fluid That Can Not Be Identified


All of the above MUST be disposed of in a Biohazardous bag and brought to the Biohazardous waste storage

Care must be taken to clean up these bodily fluids safely. This necessitates special equipment and methods of disposal, as bodily fluids can pose a serious health risk to anyone who might come into contact with them if not cleaned carefully and thoroughly. Body fluids are a source of infectious micro-organisms, including bacteria and viruses, some of which are extremely harmful and/or incurable, such as Hepatitis B & C and HIV. Needles and other sharps also need to be handled with care for this reason.

The main risk from bodily fluids is infection following hand to mouth, nose, or eye contact during clean-up. There is also a risk of infection via broken skin. The cleaning agents used themselves may have harmful properties too, causing skin irritation, dermatitis, or eye damage. For these reasons, it’s recommended that anyone cleaning up and disposing of blood and other bodily fluids uses the following PPE:


  • Eye protection


  • Disposable coveralls with a hood


  • A disposable plastic apron


  • Wellingtons or waterproof disposable overshoes

Waterproof and abrasion-resistant gloves (e.g. nitrile gloves. Should you also need to dispose of needles or other sharps, we recommend the use of special needle-resistant gloves)

As a rule, any part of the body or clothing that could come into contact with bodily fluids should be covered, and following clean-up you should assume everything is contaminated and should therefore be cleaned and disinfected or disposed of – more on decontamination later.
