COVID-19 and Virus Disinfection in Baltimore, MD

Because viruses are capable of causing disease, they can qualify as biological hazards. The level of risk depends on the virus, route of exposure, setting and task. The actual hazard should determine the disinfection plan. Protective equipment, access control, cleaning and an appropriate disinfectant all have roles, but no single step replaces the others.

A targeted residential area might be completed during a single visit. A school, large office or commercial facility could require more time or cleaning in separate stages. The schedule varies based on access, contact times for products, sensitive surfaces, furnishings and the number of rooms. Have the scope list the areas being treated and all guidance about reentering them.

An EPA-registered disinfectant should have label directions supporting the target virus or an emerging viral pathogen. Rely on the label, not on perceived strength or fragrance. You can find the required contact period, protective equipment, application method, dilution and permitted surfaces on the label so the disinfectant works as intended.

The virus that causes COVID-19 is a biological agent, so work in the presence of known illness calls for precautions against exposure. Setting and the presence of regulated waste, bodily fluids or blood determine the precise cleanup category. Do not treat standard surface disinfection as equivalent to hazardous waste removal or blood cleanup.

Coverage does not apply by default. Depending on its terms, a policy may treat routine or preventive disinfection as maintenance and another event differently. Explain the reason for the work when calling your insurance company, then ask about the deductible, exclusions and records you must submit. For the claim check, retain the invoice and photos together with the product information and scope.

You can use alcohol-based hand sanitizer to reduce germs on your hands when washing with soap and water is unavailable. Use a product with at least 60 percent alcohol and rub all hand surfaces until dry. Rooms, electronics and furnishings should not be disinfected with hand sanitizer, which is intended for hands. Use soap and water to wash hands with visible dirt.

Alcohol can inactivate the virus that causes COVID-19 when the concentration, surface and wet contact time are appropriate. On hard surfaces, follow the label for an EPA-registered product or a different product endorsed by the surface manufacturer. Keep alcohol spray away from flame and heat, and do not expect a rapid wipe to meet the needed contact time.

Begin in the rooms the ill person used and at the surfaces they touched. After keeping others away, clean off visible soil and treat compatible hard surfaces according to disinfectant label instructions. Wash suitable fabrics according to their care directions. A professional visit can help with large shared spaces, sensitive materials or a room-by-room scope that needs records.

Clean visible soil first, then apply an EPA-registered disinfectant that is suitable for the surface and target virus. Cover the surface fully and keep it wet for the contact time on the label. Follow label requirements for protective equipment and ventilation, and keep every cleaning chemical separate from the others.

Determine whether the wood has a seal, then consult the furniture's care guidance and the disinfectant's label. After a spot test, you may apply a compatible product to sealed wood. Unfinished or delicate wood can stain, swell or lose its finish, so avoid soaking it. Use a method suited to the material when the label does not permit the surface.
