The short answer
Personal Protective Gear
The first layer of equipment protects the people doing the work. You will see disposable gloves, boots, and coveralls that keep blood, bodily fluids, or sewage off skin and clothing. Respirators or N95 masks filter airborne particles, and goggles shield the eyes from splashes. This gear is a basic part of any biohazard cleanup, whether the mess is small or large.
For larger spills or sewage backups, the pros may wear full-face respirators and waterproof suits. The level of protection rises with the risk of infection or contamination. You should never touch biohazard materials without similar protection. If you feel unwell after exposure, see a doctor. Your safety comes before any cleaning effort.
- Disposable nitrile or latex gloves
- Waterproof boots or shoe covers
- Coveralls or Tyvek suits
- N95 masks or respirators
- Goggles or face shields
Containment and Removal Tools
Once protected, the next step is to contain the area so contaminants do not spread. The pros use plastic sheeting and tape to seal off doorways and vents. They also set up negative air machines with HEPA filters to pull particles out of the air. These machines help keep the rest of your home safe during cleanup.
For removing contaminated items, you will see shovels, scrapers, and heavy-duty trash bags. Absorbent pads and powders soak up liquids like blood or sewage. All disposable materials go into labeled biohazard bags for proper disposal. Hard surfaces like tile or concrete may need scrubbing tools and brushes to remove every trace.
- Plastic sheeting and duct tape
- Negative air machines with HEPA filters
- Absorbent pads and powders
- Shovels and scrapers
- Red biohazard bags
- Heavy-duty trash containers
Cleaning and Disinfecting Chemicals
After removal, the area needs thorough cleaning and disinfection. The pros use hospital-grade disinfectants that kill bacteria, viruses, and fungi. These chemicals come as sprays, wipes, or concentrated solutions mixed with water. You might also see antimicrobial treatments that prevent mold and mildew from growing on damp surfaces.
For sewage or floodwater, the pros apply stronger disinfectants because the water may carry harmful pathogens. They often use specialized cleaners that break down organic matter before disinfecting. The choice of chemical depends on the surface type, whether it is porous wood or non-porous metal. Always follow safety labels if you attempt any cleaning yourself.
- Hospital-grade disinfectants
- Antimicrobial sprays
- Enzymatic cleaners for organic waste
- Quaternary ammonium compounds
- Hydrogen peroxide solutions
Drying and Air Filtration
Biohazard cleanup often involves wet materials, so drying equipment plays a key role. Air movers, which look like portable fans, circulate air to speed up evaporation. Dehumidifiers pull moisture from the air to prevent mold growth. These machines work together to dry floors, walls, and carpets after cleaning.
HEPA air scrubbers are another common piece of equipment. They filter out tiny particles like mold spores or dust that may remain in the air. The pros position these machines strategically to create airflow patterns that push contaminated air out. Drying can take a day or more, depending on how much moisture is present.
For sewage or floodwater cleanup, drying is critical because damp conditions encourage bacteria and mold. The pros monitor moisture levels with special meters to know when surfaces are truly dry. If your home has been flooded, the same drying equipment applies.
Specialized Equipment for Sewage
Sewage backup cleanup uses several specialized tools beyond basic biohazard gear. You will see submersible pumps that remove standing water from low areas of your home. Wet vacuums suck up remaining liquid from floors and carpets. These machines handle contaminated water without spreading it further.
The pros also use thermal imaging cameras to find hidden moisture inside walls or under flooring. This helps them locate all areas that need cleaning and drying. For large sewage spills, they may use truck-mounted extraction units with powerful suction. The equipment list grows with the size of the contamination.
If you face a sewage problem in your home, the same equipment applies. You can read more about wastewater cleanup and toilet sewage cleanup on this site. Remember that biohazard cleanup is not a do-it-yourself task for most situations.

Water damage does not wait
Water keeps spreading into floors and walls, so it is worth acting early. Calls are answered 24/7.

Can I clean up biohazard materials myself?
Small spills like a few drops of blood may be manageable with gloves and disinfectant. Larger spills, sewage backups, or floodwater require professional equipment and training. The risk of infection is high, so you should avoid contact and let the pros handle it.
What happens to the contaminated items after cleanup?
Disposable items like gloves, pads, and damaged materials go into red biohazard bags. These bags are sealed and disposed of according to local regulations. Some items may be cleaned and returned, but porous materials like carpet or drywall are often removed and discarded.
How long does biohazard cleanup take?
The time depends on the size of the area, the type of contamination, and how much drying is needed. A small spill might take a few hours, while a sewage backup can take a day or more. The pros work until the area is clean, disinfected, and dry.
