Sanitization & Fogging planning tools
Work through cost, hiring, insurance, first steps and disposal at your own pace.
The tools on this page are built for the moment a fogging or electrostatic proposal lands on your desk and you are not sure how to judge it. Each one breaks a single choice into questions you can answer without technical training. How big is the space? What surfaces are in it? Can it be emptied? Does it share an air system? Are there electronics or food surfaces? What kind of setting is it? From your answers, each tool gives you something concrete. You may get a cost range with its drivers, or a readiness score with open questions. You may get a claim file, a step-by-step action list, a waste category, or a risk level for doing it in house. The results are shaped for this field, so a transit supervisor and a childcare director each get advice that fits.

The tools work best in order. The First Twenty-Four Hours Planner helps you respond after an illness outbreak or a report of contamination. It covers what to close off, who to tell, and what to photograph before anyone treats anything. The DIY or Call a Pro check asks whether your own staff can handle it with a proper wipe-and-wait routine. Or it may show that the size and the space call for a company with fogging or electrostatic gear. The Cost Range Estimator and the Provider Vetting Checklist help you compare quotes on the actual work, not on promises. The Waste and Disposal Classifier sorts leftover product, dirty materials, and covers into the right waste streams. The Insurance Claim Organizer helps when a contamination event may be covered.
The tools have limits, and we want to be clear about them. They cannot read a product label for you or inspect your ducts. They cannot know whether your county limits fogging in childcare settings. Their results are for learning and reflect only what you enter. A cost range is a planning aid, not a bid. A readiness score measures what you have confirmed, not the company's real skill. A waste category is a starting point for a question to the local office, not a final ruling. A risk level is a reasoned prompt, not a safety clearance. Use the tools to sort out your thinking and your questions. Then check every conclusion against the label, the company's written method plan, and the rules where you are.

Sanitization & Fogging numbers worth knowing before you plan
Fogging proposals tend to arrive with bold claims and dramatic photos of mist rolling through a gym. From the sales sheet alone, it is hard to tell whether the service will do anything useful. The numbers below are meant to ground that judgment. They show how buildings actually spend on disinfecting, and how much of the work is spraying versus getting ready. They show what regulators have said about product labels and spray methods. They also show what health agencies have found about germs spread by surfaces and how often to clean. Read them before you sign a repeat contract. They help you tell a program built on real risk from one built on looks. Each number links to its source, so you can weigh it for your own building.
- 180-460 ppm
A WHO expert review notes WHO's 2020 interim guidance strongly recommended against spraying or fogging disinfectants in occupied spaces, and lists U.S.-approved hypochlorous acid at 180 to 460 ppm.
Read with care: The fogging statement is quoted secondhand from WHO's May 2020 interim guidance, which was written for the COVID-19 context.

- 250 RLU
A 1,300-bed UK teaching hospital study proposed a stricter ATP pass/fail benchmark of 250 RLU for surfaces, revised down from the earlier general benchmark of 500 RLU.
Read with care: RLU values are not comparable across meter brands, and ATP measures organic residue, not whether pathogens were killed.

Hydrogen peroxide vapor room decontamination took a mean of 2 hours 20 minutes per patient room versus 32 minutes for conventional cleaning across 1,565 rooms in a U.S. hospital.
Read with care: Hospital-grade vapor systems differ from portable foggers used in homes and offices, and the study is from 2009.

EPA's 2016 Emerging Viral Pathogen policy has been activated for SARS-CoV-2 (January 2020), mpox (August 2024), Marburg (October 2024), and hantavirus and Ebola (May 2026).
Read with care: The policy is voluntary and allows only limited off-label claims in technical materials; it does not change the application methods allowed on a label.

Questions about the sanitization & fogging tools
Which tool should I use first when a vendor proposes fogging?
Open the Provider Vetting Checklist. It asks the questions that show whether the proposal is sound. These include the label wording that allows the method, the plan for cleaning first, the re-entry time, and the air system steps. If the vendor can answer those clearly, move on to the cost estimator. Use it to check whether the price matches the work.
Do the tools save my facility information?
They run in your browser and give results you can copy or print. Do not enter building names, addresses, or details about the people inside. The tools are meant to help you plan and talk with others, not to serve as a record. Keep service records, labels, and written method plans in your own building file, where you can find them later.
Can the cost tool compare fogging against a wiping program?
It shows what makes fogging or electrostatic work cost more or less. Examples are how long the space must be empty, handling the air system, and protecting electronics. That helps you see where a wiping program may cost less or more in labor. It does not model your cleaning staff. Use its list of cost drivers as the basis for a side-by-side talk with a company.
Are the tools relevant for a bus or a fleet vehicle?
Yes. Several tools ask about the setting and adjust for a cabin. They weigh short turnaround, closed-in air, dashboard electronics, and fabric seats. They also weigh whether electrostatic spraying makes more sense than hand-wiping the handrails and seat backs. The disposal and vetting tools work for vehicles with no change. Vehicles are one of the settings where fogging fits least well, and the tools say so.
What does the DIY tool treat as a stop sign?
There are several. Any request to fog while people stay in the space is one. So is any visible dirt or body fluid that has not been removed. So is any product whose label does not allow the planned method. Any plan to use ozone in a building with people in it is another. And so is any space with a shared air system that cannot be closed off. Each one moves the result toward calling a pro or rethinking the method.
Can I use the vetting checklist on my current janitorial contractor?
You can. It often shows whether a contractor tacked on fogging without training. The checklist asks whether the label allows the method and how the contractor controls dilution. It asks how they confirm surfaces stay wet long enough, how they coordinate with the air system, and how they record re-entry. A contractor who cleans well but cannot answer those items should probably stick to cleaning. They can leave the spraying to a specialist, or get trained.
Do the tools account for my state's rules?
No. They describe common practice and flag where local rules often apply. Examples are limits on who can be present in childcare and food settings, duties to notify people, and waste handling. Rules vary by state and county, so check with the local office before you act on any result. The tools are meant to raise the right question, not to answer it for where you are.
