Current Fleet Cleaning Limitations
Overcoming the challenges of current cleaning methods is crucial to making a case for ozone treatment as a better option. Traditional cleaning techniques often fall short in terms of efficiency and safety, pushing fleet managers to explore alternatives that can deliver more reliable sanitization.
Problems with Chemical Cleaners
Chemical cleaning products come with their fair share of risks. Many industrial cleaners contain volatile organic compounds (VOCs), which are linked to respiratory problems, skin irritation, and headaches. Even products labeled as "green" or "natural" aren’t always free from harmful ingredients, according to research by the American Lung Association. Additionally, residues left behind by some cleaners can reduce the effectiveness of subsequent disinfectants.
These chemicals don’t just pose health risks – they also harm the environment. VOC emissions contribute to poor air quality, while chemical runoff can contaminate water supplies and soil.
"It’s ironic that the chemicals we’re deploying in vain for one health crisis are actually fueling another." – Erica Hartmann, Associate Professor of Civil and Environmental Engineering at Northwestern University
The drawbacks of chemical cleaners also extend to how they affect fleet operations.
Impact on Fleet Operations
The issues with traditional cleaning methods go beyond health and environmental concerns – they also disrupt operational efficiency. Regular cleaning is vital to protect vehicle components and address seasonal challenges like salt buildup during winter. However, current practices often deliver inconsistent results.
Here are some of the main operational challenges:
- Extended Downtime: Labor-intensive cleaning processes keep vehicles out of service for longer periods.
- Inconsistent Results: Manual cleaning can vary in quality, potentially missing critical areas.
- High Resource Use: Excessive reliance on water and chemicals drives up costs.
When cleaning is inconsistent, it not only increases the risk of pathogens remaining on surfaces but can also hide early signs of mechanical problems, such as worn lines or electrical issues. For instance, studies have shown that viruses like SARS-CoV-2 can survive on materials like plastic and stainless steel for up to seven days. This highlights the importance of thorough and effective sanitization methods.
Ozone Treatment Method
Ozone treatment plays a critical role in disinfecting vehicle fleets, thanks to ozone’s strong sanitizing capabilities. However, it’s essential to follow strict safety guidelines to ensure both effectiveness and safety during the process.

- Treatment Process: Run the ozone generator for 30–90 minutes. During the final quarter of the treatment time, turn on the air conditioning to deodorize the vents and HVAC system.
Safety is a top priority throughout the process. The following measures should be in place:
| Safety Protocol | Implementation Details |
|---|---|
| Area Access | Keep all personnel out of the treatment area. |
| Ventilation | Ensure proper airflow after the treatment is complete. |
| Monitoring | Use timers to control the treatment duration precisely. |
| PPE Requirements | Provide technicians with appropriate protective gear. |
| Emergency Plans | Have clear procedures for accidental ozone exposure. |
By following these steps and safety measures, fleets can be disinfected effectively while keeping technicians and others safe.
Scheduling and Timing
Proper scheduling is key to balancing thorough disinfection with minimal fleet downtime. A typical ozone treatment process includes:
- Treatment Duration: The active ozone treatment itself takes 30–90 minutes.
- Ventilation Period: Allow 30–60 minutes for ventilation after the treatment.
- Total Process Time: Including preparation and ventilation, the entire process takes about 2–3 hours.
For consistent results, ozone treatments can be scheduled as part of monthly or quarterly maintenance routines. After treatment, ventilate the vehicle for at least two hours per hour of treatment to ensure safety and maintain the sanitizing benefits. This approach ensures a balance between effective disinfection and operational efficiency.
