Welcome Reception

Welcome and Opening Remarks

Keynote: Old Friends, New Threats, Biofilms & Now Come the “Superbugs”

Presenter: Dr. Greg Whiteley, PhD, Whiteley Corp.

We live with microorganisms. Many are our friends, some are our enemies, and in some cases, our close friends can easily adapt and become our enemies. We are all in a constant “Game of Thrones” as we fight for survival, domination, and freedom from disease.

In this keynote address, we will review some of the momentous changes that have orientated our current living standards in the first world. We will track the belief in “miasma” through the invention of microscopes and bacterial awareness, through to the invention of antibiotics and the risks posed through antimicrobial resistance. We will see that liberation from diseases of the past, diseases that resulted in morbidity, disability, and even untimely death, is again under threat from selective evolutionary pressures as a direct result of human invention.

And because of this, the cleaning industry has come right back to the center of the action in a global resurgence of concern over the transmission of bacterial, fungal and viral diseases due to poor hygiene standards. Our more recent understanding of the role of biofilms in the transmission of disease-causing microbes, and the role of biofilms in the mediation of infection add to the difficulty of effective cleaning practices. Still another feature of this resurgence in the importance of cleaning science has been the advances made in modern microbiology and microbial genetics.

Within this dynamic field, the challenge is out there for the cleaning industry and cleaning science in particular to lift its standards. This might include the development of new cleaning standards, the validation of cleaning measurement and methods, and the demonstration of integrity that allows both the client and the service provider to come to a valid understanding of the actual level of cleanliness achieved by a cleaning process.

This presentation will conduct an overview of the changes, the challenges and the risks to humanity, that are all bound up in our cleaning science deliberations.

Session 1: Threats to Human Health (Infection Control, Pathogens, Exposures, and the Human Microbiome)

Presenters and panelists: Andrew Maier PhD, Cardno Chem Risk; Richard Shaughnessy PhD, University of Tulsa; David Harry PhD, Geerpres. Panel moderator: Greg Whiteley PhD, Whiteley Corp.

Do Fresh Air and Clean Classrooms Have Anything to Do With Our Children’s Health in Schools? | Richard Shaughnessy, PhD
Infectious disease transmission in elementary schools is recognized as a public health problem. Children who are infected with a variety of respiratory and GI diseases and subsequently become ill, put their family members at risk, as well as compromise their learning process due to episodes of absenteeism. An ongoing study in a large school district in the western U.S. has generated initial data showing the effectiveness of a frequent and standardized cleaning protocol to reduce contamination on high contact/transmission surfaces when intervention and control schools are compared. The goal of this multi-year study is to demonstrate the effectiveness of a standardized and economical approach to custodial cleaning, as measured by significantly reduced student absenteeism. The presentation will also detail work that has been completed on the presence of desktop organisms, the frequency that desks should be cleaned, and the relationship to ATP.

Cleaning and Asthma – A Look at Current Safety Assessment Weight of Evidence Methods | Andrew Maier PhD
Causal relationships between cleaning professions and asthma continue to receive attention in occupational health research. The safety assessment includes hazard assessment, exposure assessment, and integration of these assessment components. An asthma product safety assessment framework was developed to assess use of products in residential and commercial cleaning. Application of the framework identified task-based exposure data as an important gap. As a result, a field simulation study was developed to assess task-based exposures for cleaning tasks representative of work done by professional home cleaners. The data on hazard and exposure were used to identify task-based safety profiles.

From the Floor Up — Microbiological Findings of Laundered Microfiber Mops | David Harry, Sustainable Scientific Solutions
Prior to 2002, one cotton string mop was used to clean three hospital rooms with three gallons of water and then replenished. The single microfiber flat mop per room concept was introduced in 2002 at UC Davis with EPA research; the goal was to reduce cross-contamination. It became the global standard. Recent research has uncovered that the properties that make microfiber so effective also prevent pathogens from being effectively removed from them. Microbiological and scanning electron microscopic (SEM) documentation will be presented that show current laundry processes which are designed not to damage the microfiber are allowing pathogens to remain in the microfiber. The situation is compounded by microfiber’s neutralization of healthcare disinfectants.

Session 2: Down And Dirty: Research To Practice – Practice To Research

Featuring: John Richter, Miami Univ. of Ohio; Michael Pinto, Wonder Makers Environmental; Cliff Zlotnik, IDEAZ; and Eugene Cole, LRC Indoor Testing & Research

A Cleaning-Effectiveness Evaluation of High-Flow Fluid Extraction Cleaning of Floors with Recycled Cleaning Solution for Water Conservation & Optimum Cleaning Efficiency | John Richter, Miami Univ. of Ohio
This study evaluated whether effective cleaning can be achieved when using recycled cleaning solutions, i.e., cleaning solutions that have been previously used. Historically, common cleaning methods such as string mop cleaning and window cleaning have reused cleaning solution, but little has been tested in terms of cleaning effectiveness. Specifically, the question remains whether using recycled cleaning solution for high-flow fluid extraction produces effective cleaning results. This evaluation used multiple evaluation techniques of cleaning solutions, such as ATP measurements, pH and conductance, as well as gloss testing, to evaluate the effectiveness of cleaning with recycled solutions. Field and experimental data in multiple environments and surfaces will be presented for evaluation. The aim is to determine whether cleaning with recycled solutions is feasible and how many reuses can be achieved before cleaning effectiveness is reduced below accepted cleaning standards.

Can Mold on Carpet Be Properly Remediated While Still Following the Standard of Care? | Michael Pinto, Wonder Makers Environmental There is considerable confusion in the minds of restoration professionals regarding the proper approach to carpets where visible fungal growth is present. This presentation reviews the current standard of care and uses a case study to show the feasibility of an approach that works. The key lessons of using personal protective equipment for workers involved in the initial HEPA vacuuming, treating the work as a mold remediation project, and choosing the equipment and chemicals that have a documented history of success in eradicating fungal contamination, are ones that can benefit the entire industry.

Cleaning and Disinfection in Long-Term Care Facilities: A Deadly Challenge | Eugene Cole, LRC Indoor Testing & Research
Due to the aging population of the United States, the proportion of people 65 or older is steadily increasing, currently comprising 15% of the total population. By 2030, the amount of those aged 85 years and older in the United States is predicted to double. It is alarming to note that while hospitals have strict cleaning and decontamination protocols they must follow in accordance with government mandates, most long-term care facilities (LTCFs) do not, despite the immunocompromised status of those they serve. Consequently, 1 to 3 million serious infections occur every year in those facilities, leading to as many as 380,000 infection-caused deaths. The major pathogens include Clostridium Difficile (C. diff), Vancomycin-resistant Enterococci (VRE), Methicillin-Resistant Staphylococcus aureus (MRSA), Acinetobacter spp., and now the emerging fungal pathogen, Candida auris. The economic costs of such infections are already ranging from $673 million to $2 billion each year, with only increases projected. While there is emphasis on hand hygiene, antimicrobial stewardship and staff training and surveillance, there remains a scarcity of detailed information from credible research studies as to a consensus framework protocol for adequate routine and outbreak cleaning and disinfection of LTCFs. Thus, the need for practical, cost-effective, and science-based approaches to cleaning and decontamination as a means of nosocomial pathogen transmission prevention and control in LTCFs has never been more important.

Watching Paint Dry | Cliff Zlotnik, IDEAZ
An estimated 80% of walls and ceilings cleaned as the result of smoke and fire damage will also be painted as part of the remediation process. As an added measure to prevent the release of residual smoke odor and/or discoloration, a significant percentage of these heat- and smoke-damaged surfaces are coated with a “smoke sealer” as a primer prior to painting. This presentation describes a method for the comparative evaluation of the odor barrier properties of coatings.


Session 3: Practical And Effective Uses And Measurements Of Cleaning Effectiveness

Featuring: Andrew Maier, Cardno Chem Risk; Kris Rzesnoski, Encircle; Jeff Merrihew, Janitronics; and Peter T. Edelstein, Clean Carpet, Brazil

How To Turn A $100,000 Loss Into A $2 Million Disaster | Kris Rzesnoski, Encircle
This presentation outlines the challenges two individuals went through when the restoration process was done wrong. Two different oxidizers, two different restorers, two different insureds with one similar result. This presentation will highlight the assumptions made by restorers, discusses the insurance carrier’s failure to understand the magnitude of the damage, and the resulting impact on the contents, structures, and occupants. In this presentation, Rzesnoski presents his thought processes and actions to try and resolve this situation as an independent party.

ATP For Cleaning Process Monitoring | Jeff Merrihew, Janitronics
ATP monitoring used as a tool to verify cleaning efficacy can provide both challenges and benefits. ATP testing is frequently called upon to ensure compliance to the set standards, refine current cleaning processes and evaluate the effectiveness of potential new ones. But ATP’s relatively easy process can sometimes lead to misuse and the collection of improper data.

What Is A Clean Carpet? | Peter T. Edelstein, Clean Carpet, Brazil
A carpet is judged clean when 1) it is free from dirt; 2) it is free from marks or stains; and 3) it Is free from smells. Clean is a subjective concept. People have different sensitiveness on smells and visual aspect therefore it must be measured in order to achieve an accurate assessment of cleanness. In order to achieve an accurate assessment of cleanness, a measurable system must be used. Edelstein chose Hygiena System Sure Plus using Ultrasnap ATP Surface test. Results are offered as RLUs (relative light unit). Since there are no industry standards for RLUs for carpet cleaning, a test of five different sites was used to determine the accurate number for clean and not clean. Measuring took place in each step of the cleaning process after carpet was completely dry. Dry measurement was taken using FLIR MR 176 surface humidity levels. Readings on FLIR should be below 30 in surface humidity in order to be judged dry.

Cleaning Ingredient Residuals and Considerations for Pharmaceutical Product Quality | Andrew Maier, Cardno Chem Risk
Good manufacturing practices in pharmaceutical manufacturing include specifications for equipment cleaning. Traditionally, cleaning protocols for residual cleaning materials were assessed using visual inspection and rinse-and-wipe tests. Recently the validation of product quality requires a risk-based calculation to assure the residuals of impurities (active pharmaceuticals and others) are below the level that would pose a health risk. This newer risk-based approach is embedded in modern IPSE Risk-MAPP guidance and is driving a need for harmonized health-based exposure limits for cleaning product ingredients. The HBEL derivation approach will be highlighted for a common cleaning scenario.

Session 4: Science & Research: A Paradigm For The 21st Century

Featuring: Bill McGarvey, Philip Rosenau; Ralph Moon, GHD; David Kiser, ARCSi; and John Downey, moderator.

Science and Research: Solving for Why | Bill McGarvey, Philip Rosenau Co.
Given the landscape of professional cleaning, the scientific community is more important than ever to the industry. A core competency of a trainer is the ability to connect with the trainee. Given the diverse nature of our workforce today and the technologies of tomorrow, we must be able to explain why certain procedures and protocols are to be followed. Additionally, tomorrow’s custodian will be required to serve as a health protectionist, robotics caretaker, and surface diagnostician. Without science-based information and standards, professional cleaners will never be viewed as the skilled tradespeople they are.

Science & Research: The Necessity of Paradigm Shifts in the 21st Century | Ralph Moon, GHD
Though we value the theories, standards and business models of the past, we live in a fast-paced world of paradigm shifts. No matter the field of endeavor, when we change a paradigm, we advance. Cabs to Uber, box stores to Amazon, scalpels to laser, pilots to unmanned drones, and NASA to Space X represent dramatic changes that are accepted by society because they are simply better. All of these changes would not have occurred without science and research. The only question “are we attracting and nurturing ‘far thinking’ students that let their imaginations take us into the future?”

The Value of Science/Research in the Universe of Cleaning | David Kiser, ARCSi
Why is scientific research is crucial for safe indoor environments? Why current conditions make science/research critical. How do scientific proofs help us understand how to clean properly? Using science/research to elevate the cleaning industry. The role of cleaning industry stakeholders. The importance of science/research in making homes safe, workplaces safe, and communities safe.

Session 5: Training and Technology innovations

Featuring: Allen Rathey, HFI University; Bob Robinson, Sr., Kaivac; Randy Rapp PhD, Purdue University. Panel moderator: Steven Spivak PhD

E-learning for Sharing Practical Cleaning Science with Millennials | Allen Rathey, HFI-Univ.
First-generation e-learning was mainly online text and images, more like an electronic textbook: Boring. Newer cloud-based software tools enable creating engaging and interactive learning about products and processes with strong research support, help track progress and completion, and provide a complement to hands-on learning while reaching millennials through their digital devices.

Video Training Mounted Onboard Cleaning Machines Versus Traditional Training | Bob Robinson, Sr., Kaivac
Video training devices mounted directly to cleaning equipment can greatly reduce training costs and time. With turnover rates sometimes 300% or higher, getting new workers trained properly is a difficult, never-ending task. Traditional classroom video training or person-to-person training can be quickly forgotten and expensive. Mounted video-training devices on equipment allows workers to access expert training in the field, 24/7/365, at their own pace. This helps the worker to become valuable and productive quickly and cost effectively.

Use of UAVs (Drones) for Disaster Restoration Site Conditions, Work Plan, Assessments | Randy R. Rapp and Christopher A. Baker, School of Construction Management, Purdue University
Adapting advanced technologies to disaster recovery work seems essential for commercial firms to remain economically competitive and government agencies to responsively serve the public. Unmanned aerial systems (UAS) and the sensors they carry evolve quickly to become much more capable for much less cost. Accurate and timely post-disaster information about damaged buildings and infrastructure greatly enhance the possible timeliness and accuracy of response. The presenters discuss UAS and sensor applications and performance characteristics and specifications that better enable disaster recovery activities to accomplish critical post-disaster operations. Their increased use by commercial and public disaster recovery personnel offers substantive performance improvement.

Session 6: Management Science, Efficiencies & Economics, Survey Data

Featuring: Jim Harris Sr., Janitronics; Carl Grimes, Hayward SCORE: Healthy Homes; Chuck Violand, Violand Management Associates; Allen Rathey, HFI University; and Steven Spivak PhD, panel moderator

Identification of Dust and Odors as the Predominant Driver of Perceived Symptomology in Residential Buildings | Carl Grimes, Hayward SCORE: Healthy Homes
Hayward Score developed a free, online questionnaire seeking structured data on 80 variables of three key characteristics of people living in residential buildings: Structural attributes, occupant behaviors, and reported symptomology. As of May 1, there have been over 38,000 responses distributed across the U.S. Because of the complexity and the number of variables from three different exploratory frameworks, the initial analysis was begun with a basic inventory followed by single attribute analysis to profile the three sets of factors. Among the wide range of results from a variety of methods, one building characteristic in association with symptomology stood out with a R2 of approximately 50%: Dust. Closely associated was the reporting of “off-odors,” indicating a potential need for cleaning. Follow-up data after the removal of dust is included in future studies.

While an R2 of 50% would be considered insufficient for most studies, the universality of this project provides a sufficient basis for further investigation with a series of more specific study designs. In other words, start with basic analysis, observe what's there, then select models appropriate for further investigation. This strategy of selecting appropriate models for cross-fertilization between and among the various “silos” of IAQ engineering, environmental epidemiology, microbiome, medical, and even sociology, potentially provides the most promise — and perhaps necessity — for furthering the understanding and future management of the dynamical system of interactions of the building, the people, their behaviors, and the perceived experience.

NOTE: Because this is not a standard study with tightly defined boundaries, the reporting of methods and interpretations will be different. The potential is for further investigation by a multi-disciplinary effort to identify a trend for a preponderance of evidence.

Timeless Lessons in Business From the Family Dinner Table | Chuck Violand, Violand Management Associates
Management fads come and go about as often as fashion styles change. The same is true with business expressions and terms, and the words we use in daily life. But one thing has remained relatively unchanged over the years, both in business and in life: basic human values; things like trust, gratefulness, compassion, sharing, and looking out for others. We may think the things we value in our personal life don’t translate into the business world, but they do. And usually we learned these values through daily interactions with our parents and siblings when we were kids. Let’s stop complicating business management. This presentation takes seven lessons many of us learned at the family dinner table and shows how to apply them at work to managing people of all generations. The seven lessons are: Show some gratitude; know who you’re following and what you stand for; talk to me; share what’s on the table; clean your plate; do your job; and save your fork.

Achieving Quality Using Deming Management Tips, Continual Stepped Improvement (CSI), and ICM | Allen Rathey, HFI Univ
Dr. W. Edwards Deming taught that 94% of poor work outcomes relate to the system rather than the worker, and that management is responsible for creating the system. In the years since Deming helped transform the automobile industry through management-led systems-thinking, a popular buzz phrase has been “Continuous Improvement.” People often link that expression to Deming; however, that isn’t what Deming taught. We’ll explain why “Continual Stepped Improvement”TM (CSI) is a better way and how Integrated Cleaning and Measurement (ICM) is an example of how to be successful using CSI within a Deming approach.

ISO 9001:2015 — Quality Management Systems for a Facility Service Provider in Controlled Environments | Jim Harris, Sr. Janitronics
Since its founding in 1972, Janitronics has always had a strong sense of the benefits of systems thinking. However, recently the company sought and was awarded registration for ISO 9001:2015. This key quality certification addressed the management and provision of cleaning services for cleanrooms, controlled environments and support areas for semi-conductor foundries. Very few service providers have received this certification. Harris will share the challenges the firm faced, the benefits, and the driving force behind the pursuit of the certification.
