Crime Scene Cleaning Equipment

Biohazard and Crime Scene Cleaning Equipment — What You Need and Why It Matters

Consumer-grade cleaning equipment isn't built for this work. The combination of hazardous airborne particles, biological contamination, and chemical exposure requires machines with the right filtration ratings, containment capability, and build quality to perform safely under demanding conditions. Using the wrong equipment doesn't just affect results — it creates risk for the operator and anyone in the surrounding area.

Here's a breakdown of the core equipment categories used in professional biohazard and crime scene cleanup, and what to look for in each.

HEPA Air Scrubbers

Air scrubbers are essential for controlling airborne contamination during and after cleanup. In biohazard environments, the priority is negative air pressure — running the scrubber to draw contaminated air through the filtration system rather than allowing it to circulate. Look for units with genuine H14 HEPA filtration, which captures 99.995% of particles at 0.3 microns, including biological aerosols and fine chemical particulates. Ductable exhaust outlets allow contaminated air to be directed outside the work area entirely. The XPOWER AP-2000 is a common choice in this category for its high CFM output and ductable design.

Commercial Wet and Dry Vacuums

Standard vacuums are not appropriate for biohazard cleanup. You need a machine with sealed filtration, robust construction, and the capacity to handle both solid and liquid waste. HEPA-filtered wet and dry vacuums prevent contaminated particles from being exhausted back into the air during operation. Tank capacity matters — larger tanks reduce the number of times you need to stop and empty, which minimises handling of contaminated material. Stainless steel tanks and fittings are easier to decontaminate between uses than plastic alternatives.

Ozone Machines

Ozone generators are used after the physical cleanup is complete to neutralise odours and residual biological contamination at a molecular level. They're particularly effective in trauma scenes and properties affected by decomposition where odour penetrates walls, flooring, and soft furnishings. Ozone treatment requires the space to be vacated — ozone at effective concentrations is harmful to humans and animals. Treatment time and ozone output need to be matched to the size of the space being treated.

PPE and Respiratory Protection

Operator protection is non-negotiable in this category. At minimum, biohazard cleanup requires disposable coveralls rated to the appropriate standard, nitrile gloves, eye protection, and P2 or P3 respiratory protection for particulate and biological hazard exposure. For higher-risk environments involving chemical contamination, powered air purifying respirators (PAPRs) like the JSP Powercap Infinity provide a higher level of protection and eliminate the fit-testing requirements of tight-fitting respirators. Refer to SafeWork Australia guidelines and your specific hazard assessment before selecting PPE for any job.

Foggers and Antimicrobial Sprayers

ULV foggers are used to apply antimicrobial and disinfectant solutions across large areas, including surfaces that are difficult to reach manually. In biohazard remediation, fogging is typically done after physical cleanup and before or after ozone treatment depending on the protocol being followed. Battery-powered cordless foggers are practical for crime scene and trauma scene work where mobility matters and power access may be limited.
