A Risk Assessment Based Approach to Selecting Technology

Many organizations use risk assessment methods to manage their business and comply with industry regulations. Google the term “risk assessment” and you are likely to find a definition along the lines of “A systematic process of evaluating the potential risks that may be involved in a projected activity or undertaking”. In other words:

Select a Technology that Delivers the Performance you Require in Real World Operating Conditions

Based upon our experience, we couldn’t agree more. Unique operating conditions can hinder the performance of many technologies in less than ideal conditions. Unfortunately, there is no “silver bullet” or “one size fits all” technology that works in every situation. If it were only that simple! But the fact is, typical operating conditions in the “real world” can be vastly different from the ideal conditions in a testing lab.

We get it … Selecting the proper decontamination approach can be a confusing and a frustrating experience. Especially when you have little margin for error and have to get it right the first time. Our mission is to listen and help you select the best decontamination solution that meets your needs.

Dry Fogging Decontamination Technology

Did you know? Our dry fog technology was developed in response to the international pharmaceutical communities’ need for a cost effective solution to decontaminate cleanrooms on a monthly basis.

Dry Fogging for Low to Intermediate Level Efficacy Requirements

Dry fogging has emerged as a popular method for decontaminating small to medium sized areas or confined spaces where time, cost, material compatibility and flexibility are important considerations. For these reasons, the technology has gained prominence in many industries as a viable alternative to chemical decontamination methods utilizing vaporized hydrogen peroxide (VHP) and micro-condensation. Today, Dry Fogging is used in all industries that require low to intermediate level efficacy results, fast turnaround times, and cost effective decontamination solutions.

As the name implies, dry fogging avoids wetting the surface. This minimizes potential material compatibility issues, and avoids the long aeration cycles typical of other methods. No pre-conditioning of the room is required either, further reducing the treatment time. Using a variety of dry fogging systems permits us to use different chemicals, allowing us to match the appropriate disinfectant with each client’s unique requirements. All this adds up to providing excellent value for our clients.

Validated results in lower-risk applications

In many applications, the technology is used as a viable alternative to more costly methods such as stationary aerosolized fogging or vaporized hydrogen peroxide (VHP). Wet fogging is used in all industries that require low to intermediate level efficacy results, fast turnaround times and cost effective decontamination solutions.

In the wet fogging process, a skilled technician applies an ultra fine disinfectant layer to the surface. Handheld foggers are used, so that a trained technician is able to reach more surfaces than with a stationary fogger by opening drawers, cabinets and enclosures, and changing the angle of application to minimize missing shadow areas. The wet fogging process is also used for remediating airborne contamination. By aerosolizing disinfectants throughout the entire airspace, lower level airborne contamination and odors can be controlled.

Fast results without a costly treatment

Surface Contamination

The universal decontamination premise is that you must start with a relatively clean surface before you begin treatment. Any potential interference that may impede the ability to achieve sterilization, disinfection or sanitization results must be eliminated. This means that excess bio-burden must be removed, as many chemical agents can’t adequately reach or penetrate dirty or soiled loads. Additionally, soiled areas can also react with, or absorb a decontamination agent, minimizing the agent’s efficacy and the outcome of the treatment.

We request that clients remove gross contamination and any residual product matter from the treatment zone before we initiate treatment. In practice, we find that some of our client’s don’t have the adequate resources to perform these tasks in-house. As a result, we offer a variety of supplemental services on a case by case basis in conjunction with our sterilization and disinfection services.

Supplemental Decontamination Treatment Offerings

Electrostatic Spraying: Designed to function in the presence of light organic matter
Chemical Foaming: Removes biofilm and stubborn contamination in challenging areas
Dry Vapor Steam Cleaning: Decontamination of moisture sensitive items
Pressure Washing: Removes heavy soils in moisture tolerant applications

Electrostatic Spaying Services

Electrostatic Sprayer

The Ecosense Company utilizes electrostatic sprayers in applications where the surfaces have been pre-cleaned and have a low soil level. We’ve found that the electrostatic sprayer is one of the most effective and economical application technologies available for achieving sanitization results in lower risk applications. Capable of delivering a wide range of disinfectants, the electrostatic sprayer takes a single drop of liquid and turns it into 900 charged droplets.

Those charged droplets are then attracted to the object or surface requiring disinfection, defying gravity in the process. Because of this, the electrostatic sprayer is able to reach areas that are frequently missed by traditional spray and wipe disinfection methods, including the underside and backside of objects that harbor contamination.

When it comes to the droplets, size really does matter. Turning a single drop into 900 and propelling it at high velocity, means that you use much less disinfectant in the process. Ecosense clients can now afford to use disinfectants with the highest efficacy and safety ratings that would otherwise be too expensive if applied with traditional methods.

The Benefits of Electrostatic Spraying

  • Smaller droplets mean less product usage and lower cost
  • Charged particles easily cover hard to reach places
  • Proper application typically ensures 80% to 100% surface coverage
  • Chemical choices that work in the presence of light organic matter
  • Reduces the potential for human error

Chemical Foaming Services

Chemical Foaming ServicesThe Ecosense Company utilizes the chemical foaming process to properly clean and prepare surfaces prior to more advanced decontamination treatments, or for separate sanitization treatments. One of the greatest challenges in many cleaning applications that rely solely on using liquids, is the inability to maintain the proper chemical concentration level and the specified dwell time over the duration of the entire treatment. This issue is more pronounced when treating odd shaped items or vertical surfaces prone to liquid run-off. The thick, clingy nature of foam allows us to overcome many of these barriers.

We select cleaning foams based upon a number of factors including the type of contamination we are seeking to remove, compatibility with surface materials, and their environmental impact. Our preference is to use environmentally friendly products such as enzymatic cleaners which are rapidly gaining prominence in critical decontamination applications. However, we also use alkaline cleaners to remove acid debris (pH<7) such as grease, oils and sugars, as well as acid based cleaners to remove alkaline debris (pH>7) such as calcium, rust, scale, oxide lime build-up and bicarbonates among others.

The Ecosense Company’s foaming process is also compatible with a select number of EPA registered disinfectants. In the appropriate application, our foaming process can deliver sanitization and disinfection level results in lieu of more advanced treatment methods.

Of particular importance, chemical foaming has been proven to be a very powerful tool for removing mature biofilms. When used in conjunction with our ClorDiSys decontamination method, this combination effectively addresses the source of many unpredictable spikes in microbial test results associated with biofilm dispersal and food recalls. In many food production environments, reducing the biofilm population can also greatly slow the product degradation cycle and significantly improve product shelf life. We offer highly-effective curative and preventative biofilm remediation programs that compliment your current sanitization programs.

The Benefits of Chemical Foaming

  • Effective in removing a wide variety of stubborn contamination
  • Can be used to clean and/or sanitize difficult to reach surfaces
  • Wide variety of EPA registered chemical choices
  • Environmentally friendly enzymatic and organic approved options
  • Very effective at removing and controlling biofilms

Dry Vapor Steam Cleaning Services

Dry Vapor Steaming Before and AfterThe Ecosense Company utilizes a dry vapor steam cleaning process for removing difficult contamination and encrusted product residues from surfaces in moisture sensitive applications. Our dry vapor steam cleaning equipment utilizes a combination of heat, low moisture, pressure and suction to loosen and remove contamination. In some applications, dry vapor steam held for the proper dwell time will deliver sanitization or disinfection level results. Our process is suitable to use in a wide variety of applications, ranging from cleaning single pieces of pharmaceutical or food processing equipment, to cleaning surfaces in small to medium sized spaces in preparation for more advanced sterilization or disinfection treatments.

During the dry vapor steam cleaning process, less than 5% water content contacts the surface, hence the term “dry steam”. This makes it suitable to use in moisture sensitive applications such as equipment decontamination, where electrical components are present. During the cleaning process, steam is heated up to 364 0F and delivered at pressures up to 115 PSI. For stubborn contamination, chemicals can be injected to facilitate the cleaning process. Finally, a built-in HEPA vacuum aids in collecting contamination and avoiding cross contamination.

The Benefits of Dry Vapor Steam Cleaning

  • Effective in removing a wide variety of stubborn contamination
  • Can be used in moisture sensitive environments
  • Environmentally friendly water vapors
  • Water vapors can be augmented with cleaning solutions
  • Can deliver sanitization or disinfection results in some applications

Pressure Washing Cleaning Services

Pressure Washing ServicesThe Ecosense Company uses a variety of different pressure washing systems for removing heavy contamination in moisture tolerant applications. We use heated water systems as well as systems that operate at ambient water temperatures and utilize both low and high pressure delivery methods. Food processing equipment, transportation vessels, IBC’s and any surface that is designed to be wash downed are good candidates for pressure washing. When a cleaning agent must be added to the water, we prefer to use environmentally friendly chemical surfactants that comply with the strictest water discharge requirements.

The Benefits of Pressure Washing

  • Effective in removing a wide variety of contamination
  • Fast and cost effective treatment method
  • Environmentally friendly water
  • Water can be augmented with cleaning solutions
  • Water temperature and pressure can be regulated

Airborne and Surface Contamination

It is a commonly held belief in some quarters that odor removal is a simple and straightforward process requiring little training or expertise. In our experience, odor remediation is far from a simple or straightforward process. In fact, removing challenging odors can often be as difficult as achieving sterilization results in many high-risk critical industries. Considerable expertise blending technical know-how with the appropriate technology is often required in order to successfully remove many challenging odors in a safe manner.

Odor remediation typically involves using powerful chemicals and/or gases in a commercial or residential setting. In this environment, construction materials and porous contents that weren’t designed to withstand the effects of many decontamination technologies are often present. Additionally, commercial and residential odor remediation is usually performed in less than ideal atmospheric conditions, compounded by the presence of organic matter, cellulose materials and other absorbents that work to impede the odor removal process.

Having performed over 500 odor removal projects, we understand how to successfully remediate difficult odors in a safe fashion. We know what technologies work and don’t work. We’ve used all the different odor removal technologies at some point, but have found that two in particular, chlorine dioxide and hydrogen peroxide, deliver the best combination of performance and safety.

Chlorine Dioxide Odor Removal Technology

The Ecosense Company uses chlorine dioxide products for difficult odor remediation projects. Not to be confused with chlorine or bleach, our chlorine dioxide products are non-carcinogenic with pH neutral properties, making them a safer alternative for use in commercial and residential settings. No harmful residues are generated or left behind. Of particular importance, chlorine dioxide is the chemical option which is least affected by the presence of organic matter, cellulose materials and other absorbents that commonly work to impede the odor removal process.

We often use both aqueous chlorine dioxide solution and chlorine dioxide gas together on many odor remediation projects as a one-two punch. Chlorine dioxide gas is liquid soluble, meaning that it doesn’t lose its strength in the presence of liquids, and actually supercharges the aqueous chlorine dioxide solution’s ability to penetrate and destroy odiferous bacteria and fungus. In our experience, chlorine dioxide gas fumigation is the most effective method for destroying odors in hidden or difficult to reach areas that are prevalent in odor remediation projects.

Odor Removal Technology Molecular Sizing ChartOur chlorine dioxide products can be scaled up to provide fast treatment times on large jobs and easily adjusted to remediate the strongest residential odors. Insurance companies appreciate the cost savings they enjoy by reducing additional living expense (ALE) reimbursements, business interruption (BI) insurance claims, and odor related contents replacement claims. Discerning homeowners enjoy The Ecosense Company’s ability to restore their home’s environment and value in a professional manner.

Chlorine Dioxide Odor Removal Benefits

  • High performance in challenging applications
  • Strength can be adjusted for strong odors
  • Easily scaled up to treat large projects
  • Safe pH neutral, non-carcinogenic with no residue
  • EPA registered products with organic approvals

Hydrogen Peroxide Odor Removal Technology

The Ecosense Company uses various hydrogen peroxide products and delivery methods in lower level odor remediation projects. Similar to our chlorine dioxide technology, hydrogen peroxide is non-carcinogenic to humans and enjoys a well deserved reputation as a versatile odor remediation solution.

Our hydrogen peroxide solutions are appropriate to use on both hard and many soft porous surfaces with minimal compatibility issues. No harmful chemical residue is generated or left behind. However, hydrogen peroxide does not share the unique properties of chlorine dioxide where performance is not significantly compromised by the presence of organic material or liquids. As a result, we use hydrogen peroxide in lower level odor remediation projects or applications where there is no visual soiling, residual water deposits, or contamination present.

Hydrogen Peroxide Odor Removal Benefits

  • High performance in cleaner environments
  • Dry fog, wet fog and spray delivery methods
  • Suitable for treating small to medium size areas
  • Safe pH neutral, non-carcinogenic with no residue
  • EPA registered products
