There are plenty of messes around a home or business that can be handled with household cleaning supplies. But some situations are fundamentally different.
When a property contains blood, bodily fluids, sewage, extensive mold, hazardous materials, or the aftermath of an unattended death, cleaning is no longer simply about making a surface look better. The situation may involve contamination, exposure risks, structural damage, or materials that require specialized handling.
Knowing when to step back and call for professional biohazard cleanup can help prevent an already difficult situation from becoming more complicated.
Here are five situations where attempting the cleanup yourself may not be the safest approach.
1. Blood or Bodily Fluids Are Present
A small household spill is one thing. Blood or bodily fluids associated with an injury, death, crime, or other traumatic event are another.
Blood can contain pathogens capable of causing disease, and OSHA identifies occupational exposure to blood and other potentially infectious materials as a safety concern.
The challenge is not necessarily what you can see. Blood and bodily fluids can seep into:
- Carpeting
- Upholstery
- Wood flooring
- Subflooring
- Furniture
- Walls
- Other porous materials
Simply wiping the visible area does not necessarily address contamination that has penetrated a material.
Bio-One of Sacramento provides Blood Spill Cleanup services as part of its biohazard remediation services, with trained technicians using appropriate procedures and protective equipment.
If an injury, accident, crime, or death has resulted in significant blood or bodily fluid contamination, this is a situation where professional biohazard cleanup should be considered rather than attempting to handle everything with household products.
2. You Are Dealing With an Unattended Death
Discovering that someone has died in a home or other property can be an overwhelming experience. The cleanup afterward can also involve biological contamination that isn't immediately obvious.
As decomposition progresses, bodily fluids can penetrate flooring, furniture, mattresses, walls, and other materials. Depending on how long the person remained undiscovered, odors and contamination may extend beyond the immediately visible area.
This is not a situation where ordinary cleaning products and a pair of household gloves are necessarily enough.
Bio-One of Sacramento's Decomposition / Undiscovered Death services are designed for situations where a property requires specialized biohazard remediation after an unattended death.
Professional biohazard cleanup can involve assessing affected materials, removing contaminated items, cleaning and disinfecting affected areas, and handling biohazardous waste appropriately.
Most importantly, family members should not feel that they are responsible for cleaning up the physical aftermath themselves.
3. Sewage Has Entered the Property
A sewage backup can turn an ordinary water cleanup into a contamination problem.
Sewage may contain microorganisms and other contaminants, and the CDC specifically warns people to avoid contact with floodwater that may contain sewage.
The same concern applies when sewage enters a home because of a backed-up sewer line, failed septic system, flooding, or another plumbing problem.
Potentially affected materials can include:
- Carpet and padding
- Drywall
- Insulation
- Upholstered furniture
- Flooring
- Personal belongings
- Building materials
The longer contaminated materials remain wet, the greater the opportunity for additional damage and microbial growth.
The safest response depends on the extent and source of the contamination. If sewage has spread through multiple rooms or affected porous building materials, professional assessment and cleanup may be appropriate.
Bio-One of Sacramento includes Sewage Backup Cleanup among its biohazard and decontamination services.
4. Mold Is Extensive or Connected to Significant Water Damage
Seeing a little mold around a bathroom window does not automatically mean you need a professional remediation company.
The EPA notes that small areas of mold—generally less than about 10 square feet—can often be handled by homeowners following appropriate precautions. However, larger areas, significant water damage, or mold associated with contaminated water can require professional assistance.
The CDC also recommends additional protective measures during mold cleanup and notes that certain people, including those with allergies, immune suppression, underlying lung disease, or chronic respiratory conditions, should not participate in mold cleanup.
Consider professional help when:
- Mold covers a large area.
- There has been substantial water damage.
- Mold is inside walls or other difficult-to-access areas.
- Porous materials have extensive contamination.
- The source of the moisture has not been corrected.
- The cleanup would require removing large amounts of drywall, insulation, carpet, or other materials.
Bio-One of Sacramento offers Mold Remediation services for properties affected by microbial growth and contamination.
Trying to clean extensive mold without addressing the underlying moisture problem can also allow the problem to return.
5. You Discover Needles, Sharps, or Unknown Hazardous Materials
Some cleanup situations contain hazards that cannot be safely identified or handled by simply putting on household gloves.
Discarded needles, broken glass, contaminated sharps, unknown substances, and other hazardous materials can create puncture, exposure, or chemical risks.
OSHA defines contaminated sharps as objects capable of penetrating the skin that are contaminated with blood or other potentially infectious materials.
If you discover needles or other potentially contaminated sharps while cleaning a property, do not pick them up with your bare hands or toss them into an ordinary household trash bag.
The same principle applies to unknown chemicals or substances. If you do not know what something is, disturbing it can create an unnecessary risk.
A professional cleanup team can assess the situation and determine the appropriate handling and disposal procedures.
Why "I'll Just Clean It Myself" Can Become a Bigger Problem
The desire to handle a cleanup yourself is understandable. You may want to save money, protect your privacy, or simply get the property back to normal as quickly as possible.
But professional biohazard cleanup is different from ordinary residential cleaning.
The goal isn't simply to make the affected area look clean.
A professional cleanup may require identifying contamination, determining which materials can be cleaned or salvaged, removing materials that cannot be adequately decontaminated, disinfecting affected areas, and properly handling waste.
Bio-One of Sacramento states that its technicians are trained to follow OSHA standards and use appropriate PPE when handling biohazard situations.
What Should You Do Instead?
If you encounter a potentially hazardous cleanup situation, the first step is usually to limit access to the affected area.
Keep children, pets, and unnecessary visitors away from the scene. Avoid touching or disturbing unknown materials, and don't begin tearing out flooring, drywall, insulation, or other potentially contaminated materials simply to see how extensive the problem is.
For mold, sewage, blood, bodily fluids, or other biohazard situations, professional guidance can help determine what needs to happen next.
You don't necessarily need to know exactly what the contamination is before making the call. Explaining what you discovered can allow a professional team to determine whether the situation requires specialized cleanup.
When in Doubt, Don't Put Yourself at Risk
Not every unpleasant cleanup requires a professional.
But when biological contamination, sewage, extensive mold, decomposition, sharps, or unknown hazardous materials are involved, the risks can be very different from those associated with ordinary household cleaning.
