EPA lists products by pathogen.
The right product depends on the pathogen. EPA publishes a separate list for each, shown here.
- COVID-19 / coronavirusEPA List N
- Norovirus (stomach flu)EPA List G
- MRSA / staphEPA List H
- C. diff (Clostridioides)EPA List K (spores)
- Influenza A/BAsk your matched company
- Mold + bacterial comboOften follows water damage events
- General facility sanitizationAsk about recurring service
Typical steps. Ask your matched company how it handles each one.
- 01STEPAssessment
Identify contaminated surfaces, ventilation and high-touch areas, and choose a product registered for the pathogen involved.
- 02STEPProtective equipment
Workers wear protective equipment suited to the hazard. Ask your matched company what it will use.
- 03STEPPre-cleaning
Remove visible soil first. Many product labels call for cleaning before disinfecting.
- 04STEPDisinfection
Apply the product as the label directs, keeping the surface wet for the full contact time the label states.
- 05STEPAir and ventilation
Ask your matched company whether ventilation or air filtration is recommended for your situation and why.
- 06STEPDocumentation
Ask for the products used, their EPA registration numbers, contact times and areas treated, in writing.
Ask. Then get it in writing.
- Which product, which EPA list it appears on, and its EPA registration number
- The label's contact time and the re-entry time for people and pets
- Training and safety practices: ask about IICRC training and OSHA compliance
- Written documentation for your insurer, landlord or health department
- Whether recurring service is available for your business
Eight common questions.
What disinfectants are used?+
EPA keeps separate lists of registered disinfectants by pathogen: List N for SARS-CoV-2, List G for norovirus, List H for MRSA and VRE, and List K for C. difficile spores. Ask your matched company which product it plans to use and which list it appears on.
How long before I can re-enter after treatment?+
Follow the product label. EPA says the label states a contact time, and the surface should stay visibly wet for the whole contact time. Ask your matched company for the re-entry time for the product it uses.
Is the treatment safe for pets and children?+
That depends on the product. Read the label and ask your matched company, before work starts, how long to keep people and pets out and how long to ventilate.
Can the HVAC system be treated?+
Ask your matched company what it recommends for ductwork after an outbreak and why. Do not assume any single method is needed.
Do I get documentation for a health department inspection?+
Ask your matched company, before work starts, to write down the products used, their EPA registration numbers, contact times and the areas treated. Your local health department decides what it requires.
Can I schedule recurring disinfection for my business?+
Ask your matched company whether it offers recurring service and what it would cover.
Is this covered by insurance?+
It depends on your policy and the cause. Disinfection after a covered event such as a sewage backup may be part of a claim; standalone disinfection after an illness outbreak often is not. Ask your insurer, and ask your matched company to document the work.
What's the difference between cleaning, sanitizing, and disinfecting?+
Cleaning removes visible dirt. Sanitizing lowers bacteria counts. Disinfecting kills or inactivates the pathogens named on the product label, when the label directions are followed.
Often paired with disinfection work.
- →Biohazard Cleanup
Full biohazard removal for sewage, decomposition, and chemical events.
- →Odor Removal
HEPA filtration and hydroxyl treatment eliminates airborne pathogens and odors.
- →Sewage Cleanup
Category 3 black water carries dangerous pathogens — full decontamination required.
- →Commercial Restoration
Recurring disinfection programs for offices, hotels, and multi-family properties.
