Bloodborne Pathogen

Bloodborne Pathogen Scene Cleanup

Blood, biological fluids, and tissue at a San Mateo property are regulated biohazards under OSHA 29 CFR 1910.1030. We map contamination extent using UV light, treat with EPA List N disinfectants, and confirm clearance with ATP testing before sign-off.

Decomposition

Decomposition & Odor Control

Biological decomposition at a San Mateo property generates volatile biogenic amines that penetrate HVAC systems and subfloor materials. We neutralize biogas compounds using hydroxyl generator technology β€” not masking agents β€” and verify odor elimination before closeout.

Category 3 Sewage

Category 3 Sewage Biohazard Response

Sewage backups at San Mateo properties carry hepatitis A, norovirus, E. coli, and salmonella β€” pathogens that survive on surfaces long after visible water is removed. We apply EPA-registered antimicrobials rated for the Category 3 pathogen spectrum and document drying per IICRC S500 standards.

Chemical

Chemical & Drug Lab Decontamination

Meth lab residue at a San Mateo property saturates drywall, HVAC ductwork, and framing β€” invisible but regulated under CA law. We coordinate IH sampling, perform solvent-specific decontamination, and produce state health authority clearance documentation required for legal re-occupancy.

Crime Scene

Post-Release Crime Scene Response

Crime scene remediation at a San Mateo property begins only after official law enforcement scene release. We arrive with UV mapping equipment, EPA-registered disinfectants, and DOT-compliant containers β€” and close every job with ATP verification and full insurance documentation.

Hoarding

Biohazard-Level Hoarding Cleanup

Hoarding biohazard remediation in San Mateo follows a phased approach: hazard assessment, PPE selection, pest coordination, material segregation, systematic sanitation, and odor neutralization β€” documented at every stage.

Sandra L.Property Manager, San Mateo

"The decomposition odor in my rental unit had defeated two previous cleaning companies. Crime Scene Cleaner Online found the source in the subfloor cavity no one else had checked, ran hydroxyl generators after treatment, and the ATP results confirmed complete clearance. The unit re-rented without any odor disclosure issue."
