After a traumatic incident, death, or hazardous contamination in your property, it’s natural to want to act quickly. But when it comes to biohazard cleanup, doing it yourself can put your health—and your legal standing—at serious risk.
In Seattle, all biohazard remediation must comply with federal OSHA regulations, state-level HAZWOPER standards, and strict local health codes. Blood, bodily fluids, and decomposition byproducts aren’t just unsightly—they’re dangerous. That’s why certified professionals are required for the job.
Here’s what every Seattle landlord, property manager, and homeowner needs to know before attempting a DIY biohazard cleanup.
Key Takeaways
DIY biohazard cleanup is unsafe and illegal in many cases.
Exposure to bloodborne pathogens requires OSHA-level PPE and training.
Seattle health codes mandate licensed trauma cleanup for decomposition and death scenes.
HAZWOPER rules govern hazardous substance handling—violations carry fines.
Improper disposal of biohazards can result in legal action or property condemnation.
What qualifies as a biohazard—and why is it dangerous?
A biohazard is any substance that poses a threat to human health due to potential exposure to pathogens. This includes:
Blood and bodily fluids
Human waste
Decomposition fluids
Tissue remnants
Contaminated porous materials (carpets, bedding, drywall)
These materials can carry hepatitis B, hepatitis C, HIV, MRSA, and other dangerous microorganisms. You may not see the danger—but that doesn’t mean it’s not there.
Is it legal to clean up biohazards yourself in Seattle?
In most residential settings, the law does not explicitly prohibit DIY cleaning—but that doesn’t make it legal in practice. OSHA and Washington State Labor & Industries require:
Certified PPE (gloves, goggles, masks, suits)
Proper containment and removal techniques
Approved disposal through regulated biohazard waste services
If you’re a landlord or employer, cleaning a biohazard without licensed professionals may constitute a workplace safety violation and expose you to liability or workers’ compensation claims.
In short: unless you’re trained and equipped to OSHA standards, DIY cleanup is not legally defensible.
What does OSHA require for bloodborne pathogen cleanup?
Under OSHA’s Bloodborne Pathogens Standard (29 CFR 1910.1030), any cleanup of bodily fluids must follow these protocols:
Universal precautions (treating all human blood as infectious)
Use of appropriate PPE
Exposure control plans
Proper disinfection using EPA-registered products
Medical evaluation and recordkeeping for any exposure
DIY efforts almost never meet these standards. Using household cleaners or bleach isn’t sufficient and could spread contaminants rather than eliminate them.
What is HAZWOPER, and how does it apply?
HAZWOPER stands for Hazardous Waste Operations and Emergency Response. It’s a set of OSHA regulations (29 CFR 1910.120) that governs the cleanup of hazardous substances—including bodily decomposition.
If you attempt to clean a death scene or decomposed remains yourself, you’re likely violating HAZWOPER unless you have:
Completed a 40-hour certified training
A written site safety plan
Airborne hazard monitoring tools
Emergency decontamination procedures
These standards exist to protect workers and residents from secondary exposure. Ignoring them puts you—and everyone in the building—at risk.
Why is decomposition especially hazardous?
When a person dies, the body begins to decompose within hours. This process releases:
Ammonia
Methane
Sulfur compounds
Bacteria like E. coli and Clostridium
These gases and microbes are toxic. In enclosed spaces, they can cause respiratory damage, trigger asthma, or lead to infections.
Plus, decomposition fluids often seep through floors and into walls, creating hidden biohazards that can’t be resolved with surface-level cleaning. Only professionals with moisture detection tools and removal equipment can fully remediate the space.
What are the risks of doing it yourself?
Health hazards – Without proper PPE, you're exposed to dangerous pathogens.
Legal liability – Improper cleanup may violate OSHA or state health codes.
Property damage – Incomplete remediation can cause long-term odor, staining, and pest infestation.
Insurance denial – Many policies require certified cleanup for claim approval.
Emotional trauma – Death scenes are psychologically difficult—cleaning them can prolong grief.
What does a professional cleanup team do that DIY can’t?
Certified biohazard technicians follow a multi-step process:
Secure the scene to prevent cross-contamination
Wear OSHA-compliant PPE (respirators, suits, gloves)
Remove porous and contaminated materials (carpets, drywall, bedding)
Sanitize with hospital-grade disinfectants
Deodorize using foggers or ozone treatments
Transport waste to licensed biohazard disposal facilities
Document the process for legal and insurance compliance
This is not a job for Lysol and trash bags. Professionals restore safety, legality, and peace of mind.

Biohazard Scenario | DIY Allowed? | Professional Required? | Legal Risk Level |
Blood from minor injury | Possibly | Not always | Low |
Suicide or unattended death | No | Yes | High |
Feces or urine contamination | No | Yes | Moderate |
Decomposition with odor | No | Yes | High |
Drug paraphernalia cleanup | No | Yes | Severe |
FAQs
Can I just use bleach to clean up after a death?
No. Bleach can discolor and damage surfaces, and it doesn’t fully neutralize biohazards in porous materials. Professional-grade disinfectants are required.
Will my insurance cover cleanup if I do it myself?
Rarely. Most insurers require certified professionals to validate coverage, especially in trauma or death scenarios.
What happens if I dispose of biohazard waste in the trash?
Illegal disposal can lead to fines and criminal charges. Biohazard waste must be transported and incinerated at approved facilities.
Do I need training to clean up blood?
Yes. Under OSHA law, even workplace first-aid responders need formal training to handle blood safely. DIY attempts without training are considered violations.
Isn’t professional cleanup too expensive?
In most cases, it’s covered by insurance. Even if not, the health, legal, and financial risks of doing it yourself are far more costly in the long run.
Checklist
✅ Never touch blood or fluids without PPE
✅ Contact licensed biohazard cleanup providers
✅ Verify insurance coverage for remediation
✅ Do not allow untrained staff or family to clean
✅ Document all communications for liability protection
✅ Confirm proper disposal of all hazardous materials
✅ Schedule inspection for odor or contamination residue
✅ Get certification of cleanup for landlord/tenant records
