The DomiDocs Guide to Biohazard Exposure Preparedness

“An ounce of prevention is worth a pound of cure.” – Benjamin Franklin.

When you think about being a homeowner, what potential biohazard exposures come to mind? Sometimes the signs of biohazard contamination are obvious, like rodent droppings or a backed-up sewer drain. Other times, the dangers are hidden, such as with unhealthy mold growing behind walls or contaminants circulating through your HVAC system. The key to safeguarding your home involves recognizing that biological threats can originate from both external sources (including a widespread infectious disease outbreak) and internal household issues, both of which demand proactive measures to protect health.

Are you ready for this?

It’s a fact that microorganisms naturally exist in our homes. This includes a diverse world of bacteria, viruses, and fungi (like molds and yeasts). They’re on surfaces, in the air, in our dust, and even on us – eek! As a normal part of any indoor environment, most of these microbes are harmless. However, when certain conditions within a home allow these microorganisms to thrive and multiply excessively, they can become a biohazard, posing risks to our health and the integrity of our homes. 

The three types of biohazard exposures.

Ready.gov identifies three primary categories of biological agents that could pose a threat, whether released accidentally or intentionally:

  1. Bacteria: these are harmful single-celled organisms, such as those that cause the plague or anthrax. Contaminated food, sewage backups, and pet waste contamination are all sources of bacterial biohazard exposures.
  2. Toxins: these are poisonous substances, often produced by living organisms (bacteria, fungi, or plants); examples include botulinum or ricin toxins. Botulism from improperly canned foods and aflatoxins from moldy food are examples of toxic biohazard exposures.
  3. Viruses: these are infectious agents that require a host to replicate, like the viruses responsible for Ebola or smallpox. Norovirus can quickly spread in a household from contaminated surfaces or food. Influenza and colds spread when an infected household member sneezes or coughs into the air, releasing virus-laden droplets that others in the home inhale or pick up from contaminated surfaces.

Biohazard exposure stats in US homes.

This is a tough one to pin down simply because many household biohazard exposures go unreported and are managed by homeowners themselves, especially with seemingly minor incidents like small mold patches or routine pest control. But here are a few statistics of note:

  • In 2019, the US Census Bureau reported that almost 14.8 million Americans saw mice or rats in their homes in the last year.
  • The US Environmental Protection Agency (EPA) estimates there are between 23,000 and 75,000 sanitary sewer overflows in the US annually.

And that right there should be enough to encourage you to plan for a biohazard exposure in your home. Yuck.

The Basics of Biohazard Exposure Preparedness.

Ready.gov, the American Red Cross, the National Institutes of Health, and the Centers for Disease Control and Prevention (CDC) recommend the following:

Before a Biohazard Exposure Emergency, Take the Time to:
Understand the common biohazard exposures homeowners face.

Airborne pathogens:

  • Sources: bacteria and viruses transmitted through the air, especially during illnesses like common colds, influenza, or COVID-19
  • Risks: contagious diseases, flu, colds, and respiratory infections

 

Animal and pest waste:

  • Sources: your own pet’s waste if not cleaned up promptly, as well as through insect infestations, waste/urine from mice and rats
  • Risks: hantavirus from rodent droppings, E. coli, Salmonella, and spread of parasites

 

Blood and bodily fluids:

  • Sources: accidents, injuries, illness, or even unattended deaths in a home. This includes blood, feces, urine, vomit, and other bodily secretions
  • Risks: Hepatitis B and C, Human Immunodeficiency Virus (HIV)

 

Contaminated water:

  • Sources: floodwaters, or unsafe drinking water from private wells or lead pipes in older homes
  • Risks: kidney problems, developmental delays in children from lead exposure, gastrointestinal illness

 

Contaminated HVAC systems:

  • Sources: If there’s moisture buildup in ducts or if filters aren’t changed regularly, HVAC systems can circulate allergens like bacteria, dust, mold spores, and pet dander throughout your home
  • Risks: Kidney problems, developmental delays in children from lead exposure, or gastrointestinal illness

 

Food spoilage and foodborne pathogens:

  • Sources: spoiled food, improperly stored food, including leftovers, can breed bacteria like Salmonella and Listeria
  • Risks: food poisoning

 

Hoarding:

  • Sources: homes with severe hoarding can accumulate vast amounts of decomposing food and human or animal waste, which attracts rodents and pests, and creates extremely unsanitary conditions
  • Risks: falls and tripping hazards; fire hazards; structural damage, potential for collapse, hidden damage; mental and emotional health issues; pest infestations; allergic reactions; respiratory problems due to poor air quality; infectious diseases; mold and mildew; plumbing issues

 

Mold and mildew:

  • Sources: damp conditions, water leaks (foundations, pipes, roof), flooded areas, or poor ventilation
  • Risks: respiratory issues, headaches, fatigue, allergic reactions (skin irritation, sneezing, coughing), or even long-term lung damage
  • Where it hides: attics, basements, bathrooms, behind walls, under floors, around leaky pipes

 

Sewage backups:

  • Sources: blocked or damaged drainage systems leading to raw sewage backing up into basements, bathtubs, sinks, or toilets
  • Risks: raw sewage contains a highly toxic mix of bacteria, parasites, and viruses; exposure can cause skin infections, respiratory issues, or gastrointestinal infections
  •  
Understand where external biohazard exposure information will be coming from.

External events where you’re exposed to biohazards accidentally or intentionally may or may not be immediately recognizable. Typically, biological threats would be announced by local healthcare workers who notice a pattern of unusual illnesses or through a surge of people seeking emergency medical attention for the same set of symptoms.

If a biological event were to occur, you’d be notified through emergency radio or TV broadcasts, home visits, emergency response workers, or an emergency notification to your cellular phone.

Mitigate the risks of biohazard exposures.

You can significantly reduce the risks of biohazard exposure by:

  • Addressing any water leaks in your home immediately, before they have time to cause further damage and create an environment for mold, mildew, and other biohazards to flourish
  • Ensuring proper ventilation in your home to reduce the concentration of airborne pathogens
  • Follow proper food storage techniques, such as:
    • Adhering to ‘use by’ and ‘best before’ dates
    • Keeping hot foods hot, above 140°F, and cold foods cold at or below 40°F
    • Refrigerating perishable foods within 2 hours of cooking or purchasing; this reduces to 1 hour if it’s a hot day, 90°F or above
    • Ensuring your fridge is set at or below 40°F and your freezer is at or below 0°F
    • Only placing raw meats in sealed containers on the bottom shelf of your fridge to prevent juices from dripping down and contaminating other food
    • Separating raw food from cooked/read- to-eat food
    • Using dedicated cutting boards for produce/ready-to-eat foods and raw meat
  • Maintaining a clean home, especially in bathrooms and kitchens, where microorganisms like to grow
  • Practicing good hygiene, including washing your hands thoroughly with soap and water, especially after using the restroom, before eating, and after being in public places
  • Promptly dealing with pest infestations
Protect your home by installing a HEPA filter in your furnace.

A High-Efficiency Particulate Air (HEPA) filter captures a remarkable 99.97% of airborne particles that are 0.3 micrometers in diameter. Since most bacteria and mold spores are larger, a HEPA filter is highly effective at trapping them. And while viruses may be smaller, HEPA filters can still help to reduce the overall concentration of viruses circulating throughout a home.

Ensure everyone in your family has up-to-date immunizations.

Ensuring that every member of your household has up-to-date immunizations provides: 

  • crucial protection against infectious diseases
  • limits their spread within your home
  • contributes to broader community health

 

If you’re unsure about your family’s immunization status, check with your family doctor or local public health unit.

Review/update your homeowner insurance policy.

It’s estimated that 40% of Americans can’t find an important household document when needed, so the first step is to upload your vital household documents to our user-friendly digital platform, so there’s easy access 24/7/365. 

Secondly, reassess your homeowner policy to ensure you have the best coverage to fit your needs. Compare the cost and coverage you have in place to what else is available from your current insurer and other companies. If there have been any major additions to your home and/or contents in the last year, it’s time to review your homeowner insurance policy to ensure it’ll cover your new additions.

In general, you should always have disaster supplies on hand for your family members and your pets.

The American Red Cross recommends gathering 2 emergency supply kits:

  1. A Go-Kit: with a 3-day supply of items you can carry with you, including chargers for your devices (cell phone, wheelchair, CPAP, etc.), backup batteries and/or a power bank to charge phones and other small electronic devices; as well as
    1. non-perishable food, water, and medications. Cash is also important to have on hand, as ATMs may not be working/accessible. 
      1. Nonperishable food items can include:
        1. Canned baked beans/fish/fruit/vegetables/soup/ready-to-eat pasta with sauce
        2. Cereal
        3. crackers
        4. Dried fruits
        5. granola /power/protein bars
        6. Jerky
        7. juice
        8. nuts
        9. Peanut butter/jelly
    2. A Stay-at-Home Kit: with a 2-week supply of the above items.
  2. NOAA recommends adding the following to round out your emergency disaster supply kits, where applicable:

    • masks, disinfecting wipes, and hand sanitizer
    • non-prescription medicines such as antacids, anti-diarrhea, and pain relievers
    • contact lens solution/prescription eyeglasses
    • baby bottles, formula, wipes, diapers, and diaper rash cream
    • feminine hygiene supplies
    • sleeping bags/blankets for warmth; foldable paper fans to help relieve heat
    • a change of clothing for each family member, including sensible footwear
    • fire extinguisher
    • matches in a fireproof container
    • mess kit with plates, utensils, cups, and paper towels
    • activities for kids like puzzles, games, or books

Take the time to emergency life-saving skills.

The American Red Cross recommends that adults and kids around nine learn first aid and CPR skills.

During a Household Biohazard Exposure Emergency:
Wear a face mask or cover your mouth and nose with layers of fabric that can filter the air but still allow you to breathe. This can include cotton t-shirts, handkerchiefs, or towels.

Recognize and respond to symptoms of biohazard exposure. If you have been exposed:

  • Call 911 or your local emergency number
  • Remove and bag your clothes and personal items. Follow official instructions for the disposal of any contaminated items.
  • Wash yourself with soap and water and put on clean clothes.

Check the Internet, listen to the radio, or watch TV for official news and information, including:

  • Specific areas that are in danger
  • If vaccinations or medications are being distributed
  • Where to seek medical attention if you become ill
  • Establish whether or not you should stay away from others or even quarantine.

Quickly evacuate areas if you notice suspicious substances.

Follow the directions of public health officials, which may include, but are not limited to:

  • Avoiding crowds
  • Washing your hands with soap and water frequently
  • Not sharing food or utensils with others
After a Household Biohazard Exposure Emergency:

When in doubt, contact a professional biohazard remediation company that has the training, equipment, and licensing to handle and dispose of hazardous materials correctly.

Wear personal protective equipment (PPE).

For small biohazard exposures, like a localized mold spot or small blood spill from a nosebleed, it’s important to:

  • Stop the source. If it’s a water leak, turn off the water. If it’s pet waste, ensure the pet is in a safe area, then address the waste.
  • Contain the spill. Scoop up solid materials and use absorbent paper towels or rags to soak up liquids; place them into a plastic bag for disposal. Avoid spreading material outside the original contaminated area.
  • Clean and disinfect. Scrub thoroughly using a 1-part bleach to 9-parts water solution to clean up mold and blood or bodily fluids. For human/animal waste, clean the area with detergent and water first, followed by an appropriate disinfectant cleaner.

For large biohazard exposures, such as infectious diseases, hazardous material spills, or sewage backups, do NOT attempt to clean it yourself.

Monitor your health by paying close attention to signs and symptoms for days to weeks following a biohazard exposure. These may include, but are not limited to: cough, diarrhea, fatigue, fever, nausea, or a rash.

Restock any PPE or other supplies that were used.

Replace any contaminated items in your home and/or the affected area/s.
