Infectious Disease Disinfection Provider Vetting Checklist
Fifteen questions to ask any remediation provider, a readiness score, and a copyable list of what is still unanswered.
Vendors who offer outbreak disinfection range from skilled building-cleaning firms to carpet cleaners who bought a fogger. You cannot tell the difference from a website. This checklist gives you a script of questions. It covers the areas where facility work most often falls short. Will the vendor map high-touch surfaces with your staff? Will they clean before applying product? Which products do they use, and do the labels cover the germ and the way it is applied? How do they confirm contact time? How do they handle people in the building and the heating and cooling system during spraying? What do they do with waste? What record will you get? As you confirm answers, the tool keeps a readiness score that updates as you go.
The score measures how much you have confirmed in writing. It does not rate the quality of any vendor. You can copy the list of open questions into an email or read it during a call. That way nothing slips while you are under pressure. Licensed settings such as clinics, daycares, and group homes should add their licensing agency's rules to the list, since those vary by state. A vendor who answers each item with specifics and shows you a label is easier to trust. They are also easier to defend to a board or a parent group. Some vendors answer a question about contact time with a slogan about kill rates. Some suggest fogging rooms with people in them. Either one has told you what you need to know. Check credentials yourself. This network does not certify providers.
How to use it
- 1Read the questions before you contact vendors so you know what a complete answer looks like.
- 2Ask each question during the walkthrough or call. Check it off only when the answer is specific and in writing.
- 3Check your readiness score and read why any unconfirmed items matter for an outbreak response.
- 4Copy the open-questions list into a follow-up email, or share it with whoever approves the contract.
Prefer to ask a person?
Your request is sent to the follow-up inbox. A coordinator can reply by email. Not for emergencies; call 911 first if anyone is in danger.

A worked example
Picture a made-up fitness club. Several members reported skin infections, and a doctor mentioned MRSA. The owner contacts vendors and uses the checklist. He asks if they will walk the floor with his staff to map equipment grips, benches, mats, and locker room fixtures. He asks which product they will use and if the label lists MRSA. He asks how long surfaces must stay wet and how the crew will confirm it. He asks if the club must close during spraying, and for how long after. He asks how used wipes and any thrown-out mats will be handled. He asks what written record he will get for members who ask. The first vendor gives a product name and registration number. They plan to wipe high-touch equipment before spraying. They give a re-entry time taken from the label, and they share a sample report. The second vendor offers an overnight fog and a phrase about wiping out germs. They say paperwork is available if he asks. He checks off what each one confirmed and sees a clear gap in readiness. The open-questions list becomes his reply to the second vendor. Their answer comes back with no label and no contact time, so he picks the first. The checklist gave him a record. It shows he asked the right things before spending members' dues.

Provider Vetting Checklist questions for infectious disease disinfection
What should I ask about the product's label?
Ask for the product name and EPA registration number. Then ask the vendor to show you where the label names the germ you are worried about. Ask what contact time it lists for that germ. For COVID-19 concerns, check that the number is on EPA List N. A vendor who cannot produce the label has not earned a checkmark on this item.
Is a certificate of insurance enough to verify a vendor?
It is a needed document, and many facilities require it before a vendor can come in. But it says nothing about skill. Pair it with other questions. Ask about training on contact times. Ask about worker safety under OSHA's bloodborne pathogens standard at 29 CFR 1910.1030 where body fluids are involved. Ask for references from similar facilities. Check licenses with your state or county. This network cannot do that for you.
How should I handle a vendor who insists fogging alone is sufficient?
Ask them to show where the product label allows fogging as a way to apply it. Ask if the method keeps the surfaces you care about wet for the required contact time. Ask what cleaning they will do first. If the answers are vague, leave those items unchecked and weigh the low score. Fogging can be part of a plan. It is rarely the whole plan.
What documentation should I request before signing?
Ask for a written scope. It should name the areas and list products with registration numbers and contact times. It should cover how the product is applied and how people and the air system are handled. It should also give the waste path and the re-entry time. Ask for a sample of the final report too. Licensed settings should confirm the report will satisfy their inspector. Getting this before work starts lets you hold the vendor to it afterward.
Can I use the readiness score with a school board or parent committee?
Yes. The list you can copy and the score give a plain way to show what was confirmed and what is still open. That helps when people ask why a certain vendor was picked or why a cheaper proposal was turned down. It also records the care you took. That matters if a complaint or inquiry follows the outbreak.
How should I score a vendor who answers most items well but skips one?
Look at which item was skipped. A missing answer about the product's germ claim, contact time, or cleaning first matters far more than a gap about scheduling. Follow up on the missing item in writing before you decide. If the vendor fills the gap with a specific answer you can check, update the score. If they stay vague on a core item, weigh that heavily.
Can I reuse the same checklist for our routine janitorial contractor?
Many of the items apply, mainly those about product labels, contact time, and records. Routine contracts also need a few more questions. Ask how the contractor steps up during an outbreak. Ask which products they keep on hand that list common outbreak germs. Ask how fast they can move staff to high-touch work. Use the checklist as a starting point and add those surge questions.
