How it differs from ordinary cleaning
Routine household or janitorial cleaning is designed for everyday soil and messes. Biohazard situations can involve blood, bodily fluids, decomposition, or other material that may require additional precautions and different handling.
What can determine the scope
The amount of visible contamination is only one factor.
- Type of contamination
- How long it has been present
- Whether porous materials are involved
- Whether fluids reached hidden spaces
- Property type and affected area
When to call a professional
Professional help may be appropriate when contamination is extensive, involves trauma or decomposition, reaches porous materials, or is difficult to isolate and clean safely.
Important: If there is immediate danger, an active crime scene, or a medical emergency, call 911. When law enforcement is involved, cleanup should begin only after the scene has been released.
