A lot of cleaners think biohazard cleanup is just cleaning with extra PPE.
It’s not.
Before a single contaminated item gets removed, there are steps that need to happen first.
5 mistakes we see over and over:
1. Starting work before the scene is officially released.
2. Skipping a hazard assessment and contamination mapping.
3. Failing to establish hot, warm, and cold zones.
4. Assuming general cleaning insurance covers biohazard remediation.
5. Treating blood like a surface cleaning problem.
The visible blood is usually the easy part.
The real challenge is finding where contamination traveled and preventing it from spreading further.
This is why biohazard remediation costs more than cleaning.
You’re not paying someone to wipe surfaces.
You’re paying them to identify, contain, remove, document, and remediate contamination properly.
Save this before taking on a job you’re not equipped for.
Or comment “PART 3” if you want to see how blood travels underneath flooring, trim, and walls.
