Hoarding + Biohazard Cleanup Response

SOP Safety Updated Jun 19, 2026 ยท Cleaning

Purpose

Define the response protocol for hoarding cleanouts + biohazard remediation (unattended death, blood, sewage, animal waste). These jobs are the highest-priced cleaning work - + per job - because the chemistry, PPE, disposal, + emotional toll on the crew are all unique. They are also the highest-risk jobs for cross-contamination, injury, + customer complaint. Do not take this work without a documented SOP + the right training.

Scope

Applies to:

  • Hoarding cleanouts (Level 3 - 5 on the ICD Hoarding Scale)
  • Unattended death scenes (post-coroner release)
  • Blood + bodily fluid cleanup
  • Sewage backflow cleanup (Category 3 water; covered also in CarpetCleaning water-damage classification)
  • Animal hoarding / heavy pet contamination

Excludes: Active crime scenes (law enforcement clearance required first), asbestos / lead / mold remediation as the primary service (separate licensure), or anything that should trigger a hazmat / EPA response (drug labs, mercury spills).

Responsibilities

  • Crew lead must have IICRC Trauma + Crime Scene Cleanup (TCST) or equivalent certification
  • All crew trained in OSHA Bloodborne Pathogen Standard (29 CFR 1910.1030)
  • Owner / dispatcher verifies licensure for medical-waste disposal in the work state
  • Customer signs a separate biohazard work authorization + photo-release waiver

PPE (required, no exceptions)

  • Tyvek or equivalent disposable coverall, taped at wrists + ankles
  • Full-face P100 respirator (NIOSH-rated). N95 is NOT sufficient for biohazard.
  • Nitrile gloves doubled (cut-resistant inner; chemical-resistant outer)
  • Disposable shoe covers OR dedicated rubber boots
  • Eye protection (integrated in full-face respirator OR sealed goggles)
  • Replace coveralls + gloves between rooms or after any tear

Procedure

Pre-arrival (24 - 72 hours before)

  1. Phone consultation. Photo intake from the customer if comfortable.
  2. Confirm scope, access, parking, dumpster requirements, neighbor exposure.
  3. Schedule dumpster (typically 20 - 40 yard roll-off). Confirm utility status (water, power).
  4. Coordinate with social worker, family, attorney as appropriate. Hoarding cleanouts are emotionally fraught; communication matters more than speed.

On-site setup

  1. Set up containment at room entries: 6-mil plastic sheeting + zip-wall poles.
  2. HEPA air scrubber running negative pressure to outside.
  3. Designated PPE doff zone at the egress point.
  4. Sharps containers + biohazard red-bag waste bins inside the work area.
  5. Photograph everything before any movement. Customer's items + condition are documented.

Hoarding cleanout (4 - 14 days for full house)

  1. Triage room-by-room. Sort: KEEP / DONATE / TRASH / SPECIAL (documents, medications, photos, valuables).
  2. Customer or designated family member reviews KEEP/SPECIAL piles daily.
  3. Remove trash to roll-off in marked biohazard bags if contaminated.
  4. Deep clean exposed surfaces after debris removal - chemistry per surface.
  5. Final fog with hospital-grade disinfectant (EPA List N) on areas with visible contamination.

Biohazard (unattended death, blood, sewage)

  1. Containment + PPE before entry.
  2. Remove + dispose of porous contaminated materials (carpet, padding, drywall, mattress). These CANNOT be cleaned to acceptable standard - they go to medical waste.
  3. Hard-surface decon: hospital-grade disinfectant, 10-minute dwell, two passes.
  4. ATP test + visual inspection. Areas with visible contamination after cleaning get cut + replaced.
  5. Odor remediation with hydroxyl generator or ozone (post-occupancy only; ozone is not occupant-safe).

NEVER use household bleach as your primary biohazard disinfectant. Bleach off-gases chlorine in the closed-room conditions you're working in, denatures protein but doesn't always kill pathogens at common dilutions, + corrodes equipment. Use EPA List N disinfectants (quat-based or peroxide-based) per the manufacturer kill-claim dwell time. Document the product + dwell.

Acceptance Criteria

  • All visible contamination removed
  • Hard surfaces test ATP-clean OR visually inspected + documented
  • Porous materials disposed per state medical-waste regulations
  • Customer walks the space + signs the biohazard release
  • Photo documentation archived; 7-year retention minimum
