FINFOAM Shines in New Application for Petrochemical Plants

June 8, 2021

Ever since FINFOAM became a division of Thompson Industrial Services, it has been a core service and a favorite among our industrial clients. FINFOAM was originally developed as an environmentally safe, gentle method for removing plugging and debris from air-cooled heat exchanger components. It’s incredibly effective in that application, and our teams have advanced it further by combining it with another of Thompson’s signature technologies: automated, remotely controlled positioning systems.

The non-toxic, simple nature of FINFOAM makes it surprisingly versatile, and recently our technicians have begun expanding their use of this proprietary application to other types of client projects. In the coming weeks we will be publishing a detailed white paper on these expanded service offerings utilizing FINFOAM, but in the meantime here is a summary of one of the first projects in that category. As you will see, its success provides us with a strong impetus to explore other ways that this amazing system can benefit our clients!

Petrochemical Plant Equipment

The story of this unusual project began with a request from a petrochemical plant related to a furnace at a Gulf Coast ethylene plant. The furnace’s efficiency and effectiveness had dropped well below optimal levels, and extensive research into the root causes finally revealed that the tubes in the convection section of the furnace were heavily contaminated with debris. While plant managers presumed that this debris buildup was the primary cause for the furnace’s poor performance, they also came to the conclusion that replacement of the convection section would be necessary since it had been in operation for nearly 20 years.

A Stop-Gap Cleaning Effort

The petrochemical plant engaged Thompson’s FINFOAM division to use its proven system, normally applied to air-cooled heat exchanger components, to attempt a cleaning of the tubes. The hope was that this cleaning approach would remove enough debris to bring the convection section up to acceptable levels of efficiency until the entire section could be replaced.

The Thompson team quickly built a strategy for cleaning the tubes, which were in a location that posed significant access challenges. Fortunately, the remotely controlled positioners that our teams frequently use with the FINFOAM system made it possible to apply the foaming agent to all surfaces of the tubes without cutting access holes or placing technicians in hazardous situations.

The team was also careful to mitigate the risk of water entering certain areas of the furnace, such as the firebox, during the rinse phase of the FINFOAM process. The planning and execution were highly effective, and it appeared that the cleaning had been successful in removing the built-up debris that had hindered the efficiency of the unit.

Results Surpassing Expectations

When the convection section was brought back online and tests were run to determine the efficiency gains of the FINFOAM cleaning, the results far surpassed the client’s expectations. Rather than simply bringing the performance levels up to minimal acceptable levels, the cleaning had made it possible for the unit to easily exceed the levels required for normal operation.

The client was so confident in the restored power of the furnace’s convection section as a result of treatment with FINFOAM that they decided there was no longer a need to immediately replace the section, instead postponing it to a future phase. In addition, the client expressed an intention of engaging with Thompson for additional cleaning projects at the facility to improve the performance of other furnaces.

Thompson and Innovation

This success story is just one example of the ways that our people here at Thompson Industrial Services constantly examine client needs, compare them with our present technology, and look for ways that we can make our operations do more than ever before. On a regular basis, we enter situations where an industrial facility’s leadership has become resigned to making do with poorly performing equipment, only to devise a plan that efficiently solves longstanding issues and restores levels of performance that the equipment has not provided in decades.

Please keep an eye on our website and social media for our upcoming full white paper on the use of FINFOAM in alternative settings, and get in touch with us today to arrange a consultation with one of our area experts.

2020: A Record Year for All the Right Reasons

There is scarcely a person in the United States who didn’t experience quite a number of unusual challenges in 2020. Amid the tough circumstances, though, there were some good things happening as well, and here at Thompson Industrial Services we were actually reaching some very important goals as the year went on. With a very unusual year in the rear-view mirror now, here are a few of the safety and automation goals that we were proud to achieve in 2020.

Zero SIF Actuals

If you don’t know what “SIF” stands for, that claim isn’t immediately striking. To every employee of Thompson Industrial Services, however, it represents a hard-to-believe victory on the part of our company and also highlights the genuine care that the Thompson family has for each other. SIF stands for “serious injuries and fatalities,” and we couldn’t be more pleased to attach that big fat zero to it for 2020!

The truth is, our technicians regularly work in environments with hazards such as high temperatures, enclosed spaces, caustic chemicals, and many others. In addition, many of the applications they use to do their work, from ultra-high pressure hydroblasters to solutions of incredibly powerful chemicals, pose additional risks. Over the years, Thompson management has worked very hard to understand these risks and implement policies, procedures, and especially technologies to protect our workers from them. Our perfect SIF record in 2020 indicates that those efforts have been very effective.

0.11 TIR

Another important acronym, this time referring to “total incident rate.” Our 2020 number, 0.11, is extremely low and a significant improvement over our 2019 number of 0.66. It continues a five-year trend of recording fewer and fewer total incidents every year. But the dropping number of incidents only tells part of the story. Combined with that trend has been an increasing number of total hours worked year on year, making our TIR rate an even more impressive achievement.

Other Important Safety Points

There were a few additional numbers in our 2020 statistics that round out our record safety year. The first is zero water blast incidents–the first year that we have been able to make that claim. Hydroblasting is a huge component of Thompson Industrial Services’ comprehensive service offerings, and our researchers have spent decades refining this service line with customized equipment and advanced automation.

Which brings us to the other significant number for us in 2020–namely, that across the board we doubled our use of automation compared with 2019. For many years we have based our research on the philosophy that the more we can automate our chemical cleaning, hydroblasting, and other services, the safer and more effective our teams will be. By relying more on automated technologies than in any past year, we really put that philosophy to the test–and it passed, of course, with flying colors. 

Our SIF prevention program provides detailed metrics on every job.
Our SIF prevention program provides detailed metrics on every job.

Our SIF Prevention Program

In partnership with our automation research, our SIF prevention program is the biggest contributor to the incredible safety numbers that we saw in 2020. Our system is incredibly broad-based yet also incredibly detailed, collecting metrics from our teams on the job site and passing them on to the safety councils in each of Thompson Industrial Services’ 20+ divisions.

As an example of the power of our SIF prevention program, we use it to do more than simply analyze incidents and strategize about how to avoid similar incidents in the future. The program also gives us the ability to see every “near miss” incident, which we address the same way we would an actual incident in order to prevent future SIF events from occurring. By identifying the root causes, taking action, and having thoughtful safety conversations around all types of incidents, we are proactively ensuring our systems and procedures are good, not lucky.

Looking Forward to a Safe 2021

One of the guiding principles of our safety program is to never be content with where we are. While we are extremely pleased with the safety that our teams enjoyed in 2020, we are committed to continuing to increase our use of automation, scrutinizing the data generated by our SIF prevention program even more closely, and carrying on the trend of increasing safety that we have maintained for years. It’s all about making sure that each Thompson employee has the resources and knowledge necessary to do a great job and get home safe at the end of every day.

Thompson Industrial Services: Putting People First

At Thompson Industrial Services, people always come first. That’s more than just a nice thing to say; it plays out in real, concrete ways across our entire company–and beyond. This month on our blog, we’d like to let you know about two recent events that illustrate the commitment that all of us here at Thompson have to putting people first.

While these two events are a very public way of helping people in the communities where our teams work every day, the truth is that within our company, whether in our corporate headquarters in Sumter, SC or on site at our clients’ facilities around the United States, we are always doing things to make people–both our team members and those of our clients–the priority.

Thompson team members participate in the 2020 Day of Caring at ECCO in Mt. Pleasant, SC.

2020 Trident United Way Day of Caring

The Day of Caring event is a great initiative by the Trident United Way that, appropriately enough, celebrated its 20th anniversary in 2020. Partners of the United Way, including Thompson Industrial Services, observe this special day by contributing their time and energy to helping charities, schools, and other organizations that serve the community with much-needed services all year round.

This year, Thompson pitched in by sending a team and materials to the East Cooper Community Outreach, a great center that provides hugely valuable services to those in the Mt. Pleasant, SC community that need them most. Our folks had a great time volunteering along with our colleagues at Nucor Berkeley to improve the landscaping, parking lot, and other infrastructure around the site.

BASF Charity Golf Tournament

Another great event, also coordinated by the United Way, was the BASF charity golf tournament. The divisions of Thompson Industrial Services have a long history of participating in golf events with partners around the United States…and performing quite well in them, if we do say so ourselves!

This time around, a 10-person team of Division 60’s most skilled golfers helped BASF, our great partner in Louisiana, to raise about $65,000 for local charities. As always, it was a fantastic time with great friends, great golfing, and a great feeling knowing that we were able to make a significant difference in the lives of families in the area.

Putting People First All Year Round

We often reference our corporate motto, “Be safe, be good, be great.” The fact that “Be safe” is the first part of that motto is not random! Rather, it’s a powerful reflection of the fact that in all of our efforts to make our services more convenient, more cost-effective, and more valuable for our clients, we always keep one goal as the ultimate priority: getting every Thompson team member home at night safe and sound. That commitment also extends to the great people that work at our clients’ sites.

Just as we have done in the area of automation, our leadership at Thompson has guided our company in taking the fullest possible advantage of today’s technology to empower our company-wide safety system. This system gathers enormous amounts of data from all of the projects that our teams execute across the country, analyzes that data, and produces reports and metrics that our managers use to further refine our processes and mitigate more risks as we move forward.

Making Our Employees the Very Best

But keeping our people safe on the job, as critical as that is, isn’t enough for us at Thompson. We also believe it’s important to give each employee as many opportunities as possible to develop their own unique set of skills, talents, and perhaps undiscovered potential. To that end, Thompson offers team members a wide range of ongoing education, training, and leadership boot camp opportunities, led by instructors that are leaders in their fields.

We know that when we put people first, whether that’s by doing everything we can to ensure their safety on the job, giving them chances to build out their unique abilities, or contributing what we can to help the communities that surround our regional offices, we make our corner of the world a better place for everyone. We feel incredibly privileged to be able to do that, and we so appreciate all of our corporate partners that join us in our mission to put people first.

Chemical Cleaning Experience

South Carolina Paper Mill

Recently, we were given the opportunity to clean the Number 1 Recovery Boiler at a major paper mill in South Carolina. Here’s what happened.

We rolled out our chemical safety team to assess the conditions before designing a cleaning strategy with the use of custom chemicals. Thus, our team was able to efficiently remove the fouling from boiler tubes using the chemicals and specialty equipment.

Upon inspection of the boiler chemical cleaning, our team, and the mill’s team, both concluded the project was completed. The cleaning was thorough, time was saved, and now, the business will see efficiency improve.

North Carolina Paper Mill

In another recent project, a client of ours had a liquor excursion contaminating their feedwater system. We performed complete efficacy tests immediately to determine the best route of attack. While no organic removal steps proved necessary, the challenge was still steep.

First, two boilers needed cleaning. Thanks to Thompson Industrials’ talented staff, our experts had no problem stepping up and putting in the extra hours to meet the deadline. We performed several key steps to ensure our boiler cleaning was successful. The chemical team completed a copper removal stage, acid stage, and a passivation stage.

In the end, both boilers were cleaned to satisfaction and need. The resultant inspections and flushing performed came back clean and positive.

HRSG Cleaning with EPIC(™) Technology: A Safe, Proven Cost-Effective Solution

Maximize HRSG Efficiency & Performance While Cutting Operating Costs

When you want to ensure your HRSG unit is running efficiently, it occasionally needs to be off-line cleaned professionally and thoroughly. An exceptionally effective and safe technique incorporates targeted pressure wave impulse technology applied at Mach- 5 speed utilizing EPIC (Extraction Pressure Impulse Cleaner) technology.

This patented process has been developed and perfected for HRSGs after 14 years of success and experience with it’s on-line counterpart, including on HRSGs and up to 900 Mw boilers. EPIC’s technology and its unique remote-controlled navigation positioning equipment directly focuses localized energy into the finned tube bundles to ensure its deep, penetrating and 360 degree effectiveness reaches and cleans all the crucial heat transfer surfaces without superfluous indiscriminate blasting or explosions to non-essential components or structures.

When the EPIC process is utilized for your HRSG cleaning needs, you’ll be rewarded with reduced CT back pressure, fuel costs and exit stack temperatures as well as overall increased efficiency, and much more.

Not Optimizing HRSGs’ Performance Can Be Costly

When your plant’s HRSG unit is effectively cleaned, it will restore performance that was previously lost because insulating deposits increased the CT backpressure (thus output) and increased fuel consumption. This backpressure is most frequently the result of deposits that gradually build up and affix themselves to the close-tolerance finned tubes during HRSG operation, which is standard, particularly after 5-15 years of operation. Oftentimes, DP recovery can be 3-6”, which can yield a payback in 2-4 months of operation. However, without proper cleaning, HRSG units can experience increased back pressure resulting in the overall heat rate worsening and loss of efficiency, which may even cause de-rating in peak demand periods.

Factors Leading to High Operating Costs

  • Lack of optimum cleanliness of crucial heat transfer surfaces
  • Increased CT back pressure/decreased generation because of excessive deposits
  • Lower feedwater exit temperatures necessitating additional fuel to compensate for same
  • Wasting Btu’s going up the stack rather efficient convection-transfer to the ID of tubes
  • Requiring excessively more outage duration to attempt cleaning by other methods rather than getting back on-line quicker
  • Increased fuel costs due to otherwise unnecessary use of duct burners or excessive firing
  • Due to the expense of certain other methods, cleaning intervals may be excessively delayed and/or less than the optimum quantity of harp bundles are cleaned during a project

EPIC Cleaning System

The Extraction Pressure Impulse Cleaner is a state-of-the-art cleaning technology invented and patented by PowerPlus Cleaning Systems with Thompson Industrial Services as the exclusive provider of the service. The technology is based on a process originally patented by GE (but now owned by PowerPlus Cleaning Systems) and is used for off-line cleaning of HRSG units. This system has passed the test of time for both on-line boiler-cleaning— with nearly 14 years of use— and off-line cleaning in more recent times.

EPIC Overview

The EPIC pressure wave system was designed to improve current HRSG cleaning methods and do so safely and quite effectively without damage or stretching to any combined cycle components. Although various HRSG cleaning systems exist, all had their flaws, and none can now reach the same standards and controls set by EPIC. This proprietary technology removes deposits that have built up and are lodged deep into the harp’s finned tube bundles.

How EPIC Works

The EPIC system incorporates a special device called IMPULSE(R) (internationally patented), to deliver high-pressure (<40 PSI) cleaning pulses focused and targeted circumferentially to just the troublesome heat transfer surfaces. Essentially, the system uses air shockwaves that penetrate the tube banks to dislodge (i.e. “extract”) foreign deposits. The overall cleaning system is remotely controlled by a navigation system outside of the HRSG unit in Thompson’s mobile command center. The personnel navigating the cleaning system can maneuver the system in nearly all directions to avoid obstructions, and place the system in the correct spot to clean the finned tubes and free them of the insulating deposits.


The Benefits of Using EPIC

  • Deep, thorough 360-degree cleaning of the critical tubes and fins
  • Zero damage done on any parts, components, welds, expansion joints or instruments
  • No shock or superfluous, indiscriminate blast impact to the rest of the HRSG unit
  • Highly technologically advanced; 6 camera views from command center; remote bundle differential pressure monitoring; multiple fail-safe features; borescope videoing before and after and more
  • Personnel are totally remote from the operating system
  • No scaffolding required
  • Reduced downtime for cleaning
  • Reduced combustion turbine back pressure
  • Improved heat transfer efficiency/decrease stack temperature
  • Overall financial gain
  • Optional drone inspections of HRSG and SCR

Case Study

A case study performed at a large combined cycle plant in Florida examined the benefits of EPIC technology on a Nooter/Eriksen HRSG unit. What the study found was astonishing. After a thorough cleaning with the EPIC technology, the HRSG unit experienced a decrease in CT backpressure by 4 inches of the water column. This correlated to a decrease in heat rate by 0.5 MMBtu/MWh. These impressive results yielded a payback in 1,000 full-load hours in payback, which equated to roughly $600,000 per year in this instance.


Every business in every industry should be planning for the future. To do so, they must all look to the newest technology, so they can compete and excel. For combined cycle plants, that means looking towards EPIC technology. With proven results, EPIC technology offers everything a combined cycle plant could target for; improved cleaning, safety, decreased downtime, zero damage, and an optimized HRSG unit.

If you want to improve the efficiency of your HRSG unit while saving money, request a consultation with Thompson Industrial Services to find out more about implementing Thompson’s EPIC technology and service at your plant.

COVID-19 Mitigation: Disinfection + Sanitization Services

COVID-19 has shaken the roots of every conceivable industry, business, and household around the globe. Our economy has suffered while we have been forced to retreat away and indoors. However, mitigation efforts make it possible for a slow comeback as schools, government, industry and businesses begin to reopen. Preparation for things to resume as it once was requires us to prepare, function and operate under a new norm. It’s vital that areas where human contact connects with environments that they be clean and free from COVID-19. This is where professional coronavirus disinfecting services come in!

professional coronavirus disinfecting services

Mitigation Is a Necessity During COVID-19

The hazards of contracting COVID-19 is a reality, regardless of where you go. Employers are to provide their employees with a safe and healthy work environment. Failing to provide such results in considerable liability on your part.

OSHA’s Act of 1970 (Public Law 91-596) requires employers to provide employees a “safe and healthful” working environment free from hazards that incur death or serious harm to health. OSHA reserves the right to enter a facility for inspection and/or investigation of conditions. Employers in breach of the Act of 1970 face violations resulting in a citation.

We have embraced the necessary changes to protect our employees. Measures to prevent infection while servicing contaminated environments is something we take seriously.

Thompson’s Approach to Ensuring Your Safety and Ours

Maintaining personnel safety while providing superior quality in services is a priority at Thompson Industrial Services. Both must go hand-in-hand to ensure every job is performed efficiently, safely, per government guidelines and with your best interest at heart. Training is an ever-evolving part of the industry. We incorporate cutting state-of-the-art technology and innovations with our disinfecting and sanitizing practices to remove COVID-19 from an environment.

We have a team of hundreds of professionals who are on call 24/7/365 standby for on-demand emergency services. Places such as schools, childcare, and healthcare facilities come with unexpected contamination from positive COVID cases. In these situations, our team is ready to deploy and treat all affected areas to provide you, your employees, students, or visitors a healthier environment.

Our Safety Track Record Speaks for Itself

Thompson Industrial Services has a proven track record of safety measures and initiatives in place that protects our employees. Over the past year, our total recordable incident rate (0.3) was at its lowest in history. Currently, we have passed a 6-month marker as incident-free, which is something we are quite proud of. This is due to the adoption of measures to reduce risk through automation, such as water blasting. The risk reduction initiatives also include vehicle safety. Adherence to strict driving policies is enforced through GeoTab vehicle tracking, a DriveCam weekly review, and driver training for equipment.

Layers of Protection

OSHA developed a “layer” system by which COVID-19 should be approached in prevention, disinfection, and sanitization. We strictly adhere to this “layer” system to employ attacks on COVID-19 “hot” environments.

Personal Protective Equipment (PPE)

Wear protective face masks, eyewear, gloves, and/or gowns for the appropriate environment. Every one of our team members wear hazard-specific PPE to perform our job effectively while preventing any compromise to our respiratory system, skin, or eyes.

Administrative Controls

We have implemented the below controls while also suggesting them to our customers.

  • Developing a preparedness/response plan for COVID-19 is recommended.
  • Implementation of preventative measures should be put in place through training, memos, etc. Encouraging hand washing, disinfecting work surfaces, and sneeze/cough etiquette.

Be sure your employees have access to hand soap, hand sanitizer, paper towels, and waste cans. Insist if they are sick to stay home.


Behavior and Human Performance

We encourage our employees to be proactive in monitoring themselves for any signs/symptoms of COVID-19. We strive to create this awareness among everyone. The appropriate measures are in place for screening every individual under our employ.

  • Monitor employees for compliance in preventative measures.
  • ID those who are sick, isolate if appropriate, or send them home.
  • Enforce screening measures such as questionnaires and temperature checks.

Engineering Controls and Automation

Below are a few things that you might consider implementing in your area.

  • Such things as barriers are used to protect employees who are unable to socially distance themselves from others (retail, public transportation, food/beverage drive-throughs, check-in desks at hotels, etc.)
  • Better ventilation with filters or negative airflow should be installed.
  • Enforce social distancing through markers on floors, seating, number of people allowed in, etc.
  • Encourage telecommuting or a flexible work schedule.

A great example of automation includes how we provide a snapshot of a job with digital images we take. Front-line leaders go out and take pictures of jobs. These pictures are then brought back to the office, where our automation team discusses what we can do to get the job done. It may require us to engineer special equipment.

Elimination of Hazard

This is what our business is all about!

  • Disinfection and sanitizing of all contaminated surfaces and areas.
  • Closure of facility/business.


New Protocols Require New Measures of Disinfecting

The days of using an all-purpose cleaner and paper towels to clean surfaces are gone. Because of COVID-19, the whole way we clean has been turned upside down. We almost have to take a systematic approach to cleaning to ensure we have adequately removed the potential of infection. COVID-19 has no preference, when it comes to surfaces.

Commercial and Industrial Mitigation

Disinfecting and sanitizing is required for businesses and schools to reopen. We specialize in cleaning all areas (including contaminated) where an environment has hard or soft surfaces. Our experts are skilled in using the appropriate equipment and chemicals to eradicate COVID-19 in an environment. All cleaning solutions we use are EPA registered.

EPIC HRSG Off-line Cleaning Case Study

In the spring of 2020, Thompson Industrial Services deployed the cutting-edge EPIC™ Extraction Pressure Impulse Cleaner on a Nooter/Eriksen HRSG (Heat Recovery Steam Generator) in a large combined cycle plant in Central Florida. This massive unit consists of six separate finned tube bundles 65 feet high by 32 feet across.

The result?

The combustion turbine backpressure was reduced by 4 inches of water column, resulting in a 41-day payback for the client due to increased efficiency and reduced fuel costs.

How Does It Work?

The revolutionary EPIC Extraction Pressure Impulse Cleaner derives its power from its ability to give a highly targeted 360° deep cleaning of only those tubes that have the kind of deposits that severely interfere with operational effectiveness.

The EPIC technology is so precisely focused, it doesn’t affect parts that don’t need to be cleaned. This minimizes mechanical fatigue, making components last significantly longer.

The technology involves generating IMPULSE® pressure waves within a 3-inch system chamber. Then, it directs these waves into areas of the HRSG where deposits have collected so that they can be removed. These shockwaves create a deep and encompassing cleaning energy, dislodging deposits with impressive effectiveness.

This improves combustion turbine backpressure, which in turn restores heat transfer efficiency. The process is done remotely to ensure the safety of technicians.  Real-time observation of the work is done using six system cameras monitored within the command center. This monitoring is enhanced with borescopes so that backpressure reduction can be continuously assessed.

Workers can watch the work on a large screen that gives them real-time feedback on how well the pressure waves carry out their intended job.

If a company wants to get the most comprehensive view of the results, they can opt to have a drone fly through the unit to look at the cleaning’s overall effectiveness.

The Mission

The Thompson Industrial Services team was tasked with removing deposits from the harp tubes on the inlet side of the HP Economizer #2 to the downstream side of the FW Heater #1 bundle. These deposits restrict gas flow and prevent heat transfer in areas where it’s needed.

The Work

The EPIC Extraction Pressure Impulse Cleaner successfully dislodged the deposits on the finned tubes of the HRSG. The crew worked tirelessly for five days to complete the work. This included setting up the equipment, vacuuming up the enormous amounts of debris the HRSG had accumulated, and dismantling the system once everything was done.

The plant managers and personnel were ecstatic once they pored over the data. That’s because the intensive cleaning of the HRSG resulted in massive improvements in operational performance. Backpressure was reduced by 4 inches, which decreased the heat rate by 0.5 MMBtu/MWh.

The Operations Manager even said:
“EPIC is the way to go to clean our HRSGs, and we’ll use it again in the spring for our next one.”

If you use EPIC Extraction Pressure Impulse Cleaner in your own facility, you could see similar results. What’s more, you don’t have to put scaffolding up, saving you time and money.

For more than three decades, Thompson Industrial Services has provided advanced industrial cleaning, sanitizing and disinfection services throughout the United States. We share in your commitment to health and safety, especially during serious viral outbreaks, like COVID-19.

In response to the new CDC and OSHA guidelines specifically related to Opening Up America Again, we have developed new, customized lines of Commercial Disinfection and Industrial Disinfection services.

What sets Thompson Industrial Services apart from other COVID cleaning companies?

Our highly trained teams follow CDC and OSHA guidelines as your trusted disinfection partner in creating a safer, cleaner environment for returning employees and customers. In fact, we’ve developed new, COVID-specific training programs that prepare our employees to work in potentially dangerous, COVID-exposed areas with minimal risk and maximum results. The CDC recently published Reopening Guidance for Cleaning and Disinfecting Public Spaces, Workplaces, Businesses, Schools, and Homes that we used as an anchor in developing our training, as well as our various levels of cleaning and disinfecting services.

What do the new commercial and industrial disinfection service plans include?

While safety and budgets have always been forefront in priorities at most businesses and facilities, they are bigger concerns than ever before going into these national reopening phases. As a local business with national reach ourselves, we understand the impact of large-scale changes on operations and staffing.

That’s why we provide the following tailored solutions to serve all of our clients’ varying budgets and levels of service needs.

Commercial Disinfection:

This plan offers customized scheduling on a daily, weekly, or monthly basis including a thorough wipe down of all hard surfaces using a CDC-approved bleach solution certified to kill bacteria and viruses (including Coronavirus). The CDC’s reopening procedures emphasizes that it is crucial to have a disinfecting plan when you reopen for business. This includes determining the level and frequency of service and revising this plan as the pandemic circumstances in your area continue to change.

Partnering with Thompson allows you to take the guesswork out of establishing a disinfecting plan and keeping it up-to-date with the changing environment and your unique business needs.

Add on services include vacuuming, sweeping, mopping, and on-site waste removal compliant with regulatory agencies.

Industrial Disinfection:

If your building has a positive COVID-19 case or your facility is a large industrial space, then our industrial/emergency response disinfection service is your ideal option. Our pathogen-trained response team is prepared to help you combat the current COVID-19 threat through proper disinfecting/sanitizing services, including using EPA-registered products qualified for use against SARS-CoV-2, the novel coronavirus causing COVID-19. According to the CDC, “Each product has been shown to be effective against viruses that are harder to kill than viruses like the one that causes COVID-19.” Thompson Industrial services uses these products in innovative ways that can be applied by fog, mist foam or spray to disinfect all touchable surfaces, including all door handles, computer monitors, keyboards, desks, desk chairs, public seating areas, handrails, copiers and printers, production equipment, touch screens, etc. The fog and mist spray are ideal if your facility has hard-to-reach areas or large open spaces requiring disinfection.

Additionally, our procedures are consistent with CDC and OSHA guidelines and also include proper packaging and disposal of waste in compliance with regulatory agencies.
