That's an excellent and very important question, especially for community health. Properly cleaning public trash cans is crucial after flu season, as viruses can linger on surfaces. Here’s a practical, step-by-step guide based on public health recommendations.
First, safety is paramount. The cleaning personnel should always wear appropriate Personal Protective Equipment (PPE): heavy-duty rubber gloves, safety goggles, and a face mask. Sturdy, closed-toe shoes are a must.
Start by emptying the bin completely. All debris should be removed and properly disposed of in a separate waste stream. Pre-rinse the interior and exterior with a hose or pressure washer on a low setting to remove loose dirt and grime.
Next, apply a disinfectant. The key is to use an EPA-registered disinfectant proven effective against viruses like influenza. Check the label for "kill claims." Common effective choices include diluted household bleach (1/3 cup bleach per gallon of water), alcohol solutions with at least 70% alcohol, or EPA List N disinfectants. Apply the solution thoroughly, scrubbing all surfaces—inside, outside, lid, and especially the handle and touch points—with a long-handled brush. Allow the disinfectant to dwell on the surface for the time specified on the product label; this contact time is critical for killing pathogens.
After the dwell time, rinse the bin thoroughly with clean water to remove any chemical residue. Let it air-dry completely before relining it with a fresh garbage bag. This prevents moisture from promoting bacterial growth.
Finally, don't forget the cleaner! All used PPE should be carefully removed and disposed of or washed. Hands must be washed thoroughly with soap and water for at least 20 seconds.
Establishing a regular schedule—such as a deep clean and disinfection weekly, with more frequent touch-point wiping in high-traffic areas—is the best practice for maintaining public health and safety in our urban spaces year-round.
