The organisms that drive risk here
- Mould and fungal spores following water intrusion
- Sewage-associated bacteria in Category 3 losses
- Bloodborne pathogen concerns in trauma work
- Odour-causing organisms
Controlling these is not primarily a chemistry problem — it is a consistency problem. The chemistry that fails an audit is almost never the chemistry that was specified; it is the chemistry as actually mixed, at the concentration actually present, on the schedule actually followed. Onsite generation removes the largest single variable by producing the solution at a set concentration every time.
Where it is used
- Post-water-damage antimicrobial treatment
- Category 2 and 3 water loss remediation
- Mould remediation support treatment
- Trauma and biohazard scene remediation
- Odour control through oxidation rather than masking
- Contents and HVAC treatment
- Whole-structure fogging
What it replaces
- Purchased antimicrobial concentrates carried on every truck
- Quaternary ammonium products with residue and tolerability issues
- Ozone treatment requiring evacuation
The honest position: none of these products are useless, and each has applications where it remains the right choice. What changes with onsite generation is the default — the bulk of routine sanitation moves to a chemistry that is cheaper per litre, safer to handle, gentler on equipment and impossible to run out of.
Compliance and audit position
- IICRC S500 and S520 standards of practice
- EPA-registered product where the claim requires it
- OSHA bloodborne pathogen standard in trauma work
- State remediation licensing requirements
Full citations and downloadable material are on the regulations page, and the sector-specific research citations are collected in the research hub.
Where the money comes from
- Generate onsite from a truck-mounted or shop system — no per-job chemical cost
- Faster occupancy return because the chemistry tolerates presence
- Odour control by oxidation eliminates a repeat call-back category
- Documented, registered claims available where the insurer requires them
Implementation SOP
The written procedure for this sector, in sequence:
- Remove and dispose of unsalvageable material first
- Clean surfaces before antimicrobial application
- Apply at appropriate concentration for the category of loss
- Fog for coverage in cavities and contents
- Use the registered product where the claim must be documented
- Record concentration, coverage and dwell for the file
The step everyone skips
Precleaning. Hypochlorous acid is an oxidiser, and oxidiser consumed by organic soil is not available to kill anything. A programme that sanitises dirty surfaces will underperform regardless of what the label says.
Questions
Which system do we need for a restoration & remediation operation?
It depends on daily volume and peak draw rather than on facility size. Most single-site operations in this sector are served by the EcoloxTech 300; multi-line and high-volume operations move to the EcoloxTech 1200 with buffer storage.
Do we need the EPA-registered product as well?
If your protocol, auditor, insurer or regulator specifies an EPA-registered disinfectant, then yes — HOCl-AS200, Reg. No. 101112-1. Many sites run both: generated solution for volume cleaning and sanitising, registered product where the claim must be on a label.
How do we prove it works to an auditor?
Baseline environmental swabs before implementation, the same swabs afterwards, concentration verification records, and the citation pack from our research hub. That combination is evidence rather than assertion.
What is the payback period?
It depends on your current chemical spend and volume, but most commercial installations in this sector recover the equipment cost inside the first two years, and often considerably sooner once the second-order savings are counted.
