Environmental Services
Regulated environmental hazards demand licensed professionals, proper containment, and defensible documentation. DRR brings credentialed in-house technicians to every biohazard, trauma, sewage, and lead project — no subcontractor handoff. Mold has a dedicated service page.
What We Do
OSHA Bloodborne Pathogens
Discreet, compassionate response for trauma scenes, unattended deaths, and biohazard contamination. Our technicians follow OSHA bloodborne pathogen standards and dispose of regulated biological waste through licensed channels.
IICRC S500 Cat 3 / HAZWOPER
Category 3 water intrusions — sewage backflows, flooding, and grossly contaminated water — require HAZWOPER-trained technicians, aggressive antimicrobial treatment, and full material-removal documentation.
EPA RRP Rule
The EPA Renovation, Repair, and Painting (RRP) rule mandates lead-safe work practices in pre-1978 buildings. Our EPA-certified renovators follow containment, cleaning, and verification procedures to keep occupants safe and your project compliant.
Licensed & Certified
Every environmental remediation project is backed by properly credentialed professionals — not subcontractors. Our in-house certifications cover every regulated discipline we perform.
Why DRR
Environmental remediation is not a general contractor specialty — it is a licensed discipline. Every DRR technician who enters a regulated environment is credentialed in-house. Your project file includes license numbers, air monitoring results, waste manifests, and clearance documentation in a single defensible package.
What To Do First
Biohazard scenes — trauma, unattended death, sewage backflow, regulated medical waste — are governed by OSHA 1910.1030 and ADEQ disposal rules. Improper cleanup creates legal and health liability. These steps protect both.
Crime scenes, suicides, accidents, and unattended deaths require police clearance and coroner release before any cleanup. Do not enter or alter the scene until it is formally released to the property owner's custody.
Bloodborne pathogens, sewage, and chemical exposures are regulated under OSHA 1910.1030. Untrained occupants must not enter — both for their safety and for evidentiary integrity in any legal proceedings.
Improper cleanup violates OSHA bloodborne-pathogens standards and ADEQ regulated-medical-waste rules. Disposable wipes and bleach do not neutralize biological hazards or satisfy disposal documentation requirements.
Photograph and note the situation from outside the affected zone. Avoid contact with any surface or contents within the perimeter — these become regulated medical waste requiring chain-of-custody handling.
Tell us the event type (trauma, sewage backup, hoarding, chemical spill), any law enforcement or hazmat agency reports already filed, and building access requirements. DRR's team is HAZWOPER-40 certified.
Biohazard & Trauma — Standards & Equipment
ANSI/IICRC S540
Defines biohazard scopes including blood, OPIM (other potentially infectious materials), unattended death, hoarding, and post-tear-gas residue. Mandates documented disinfection and disposal.
OSHA 1910.1030
Crews follow OSHA's bloodborne-pathogens program including Hepatitis B vaccination offer, exposure control plan, and engineering controls.
OSHA HAZWOPER
Applies to chemical-spill, methamphetamine remediation, and industrial hazmat scopes. DRR maintains current 40-hour HAZWOPER + 8-hour annual refresher across the response team.
EPA-registered disinfectants
Only EPA-registered hospital-grade disinfectants are used, applied per label dwell-time. Pathogen-specific selection per the trauma category.
Tyvek/Saranex coveralls, full-face APRs with P100 cartridges, double-glove protocol, biohazard-rated boot covers. Donning and doffing logged.
Adenosine-triphosphate luminometer testing for organic-residue clearance after disinfection. Quantifies clean — doesn't rely on visual inspection.
Red-bag biohazard waste, sharps containers, and certified medical-waste hauling chain-of-custody. Disposal manifests retained for the claim file.
Electrostatic and ULV cold foggers for surface application of List-N / List-Q disinfectants in confined spaces.
HEPA-scrubbed containment for hoarding, methamphetamine, and prolonged-decomposition scopes where vapor and aerosolized pathogens are at issue.
FAQ
Trauma scenes, unattended deaths, blood and body-fluid contamination, hoarding situations involving biological material, sewage contamination, and rodent or animal-waste cleanup. Every job is handled discreetly and per OSHA bloodborne pathogen standards.
Yes. Our environmental and biohazard technicians hold OSHA HAZWOPER 40-Hour certification (29 CFR 1910.120), with annual 8-hour refreshers. EPA NESHAP and IICRC S520 credentials cover the related disciplines we work alongside (lead, mold).
Full PPE per the OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030), engineering controls to prevent aerosolization, EPA-registered hospital-grade disinfectants validated against the relevant pathogens, and regulated medical-waste manifests for disposal through licensed channels.
Often, yes — most homeowners and commercial property policies include some coverage for biohazard remediation, sometimes with a sub-limit. We document scope and provide carrier-ready estimates. For trauma scenes there are also victim-compensation programs in Arizona that may cover cleanup; we can point you to the right contact.
Yes. Unmarked vehicles where requested, no signage, crews dressed and PPE'd outside the property line so the work itself is the only thing visible. We coordinate timing with the property owner or family.
All regulated medical and biohazard waste leaves the site in approved containers, manifested under chain-of-custody, and tracked to a licensed treatment and disposal facility. Owners receive copies of the manifests and disposal certificates as part of the closeout package.
Yes. Sewage is Category 3 water under IICRC S500 — porous materials are removed, structural assemblies are decontaminated and dried, and surfaces receive antimicrobial treatment. We document the loss for your insurance carrier the same way we document any S500 job.
24/7 dispatch with a 60-minute on-site target across Phoenix Metro. For trauma calls, we can coordinate directly with law enforcement so cleanup begins as soon as the scene is released.
