PHCC contractors and their employees).

The following table shares some

characteristics of each generation and

what they expect when they join an

association. In particular, I was fascinated

by the preferred communication style

for each generation shown above.

As shown in the graphic to the right, if

you consider that most associations are

governed and supported by the “baby

boomer” generation 1 , then one can see

the difficult choices that have to be made

in developing blended communications

that are valued across generations. For

those who have transitioned from printed

to digital magazines in order to appeal

to younger generations, Early Adopters

and Innovators (and to save production

costs), may have unintentionally caused

a greater sense of disenfranchisement

and decreased membership value for

the “silents” and the “baby boomers”

(Adapters and Late Majorities); who

still value printed content. Conversely,

printed content may be seen as “old

school” by Generation Ys and Zs: (Early

Majorities, Early Adopters and Innovators) who might then

overlay that general perception upon the association and decide

that is not for them. There is value in utilizing a broad range of

communication modes to maintain member satisfaction based on

their individual communications styles and how they consume

and share information across generations. The ultimate goal is

to continuously move the “member segmentation curve” 4 on

the previous page.

Identifying preferred intelligences of audiences

Peter Kline and Bernard Saunders in their book, “Ten Steps

to a Learning Organization,” talk about humans having

seven different intelligences: visual and spatial, bodily and

kinesthetic, interpersonal, intrapersonal, musical, linguistic,

and logical and mathematical. In addition, effective

communicators learn to read queues in identifying preferred

intelligences of their audience to maximize understanding

between the sender and receiver of information. This is called

neuro-linguistic programming (NLP). Roy Yarbrough explains

that NLP suggests that people talk to themselves differently

when synthesizing information. They take in data through

auditory, visual and kinesthetic methods. They also give others

clues as to how they prefer to receive data through their vocal

responses. For example:

• Auditory people might say … “I hear what you are saying.

Tell me again why you believe we should take this approach?”

• Visual people might say … “I see what you are saying. Show

me again why you believe we should take this approach.”

• Kinesthetic people might say … “I feel like I understand

where you are coming from. Let’s talk about how you feel

about taking this approach.”

Fun Fact — The neuro-linguistic theory also suggests there

are eye-accessing clues that indicate how a person is recalling


• Vr- Visual Remembered. Looking up and to the left indicates

remembering and event or image which occurred in the past.

• Vc- Visual Constructed. Looking up and to the right indicates

thinking of an event or image, which has not yet taken place.

(This is sometimes construed as lying)

• Ar- Auditory Remembered. Looking to our left at eye level

indicates that we are remembering a sound, word, phrase or

other auditory event which has actually taken place.

• Ac- Auditory Constructed. Looking to our right at eye level

indicates that we are trying to imagine a sound, phrase, word

or other auditory event, which we have not actually heard


• Ai- Auditory Internal. Looking to our lower left indicates

when we are in the process of conducting a conversation

within ourselves. This may be an internal debate, weighing

options or evaluating a statement.

• K- Kinesthetic. Looking to our lower right indicates that we

are experiencing a strong emotion or feeling about what is

being said or done.

Left dominant people reverse the cues described above. All

descriptions are from the perspective of the other person.

Fall 2019 • • Alabama Contractor 7






By Daniel Mullen, Sensata Technologies

Distributing water on a large scale is a challenge the world

has tackled for decades. It is a particular challenge in

high-rise buildings, and with a trend for designers to

build up in urban areas, rather than out, it is a challenge

that has become a new focus for design engineers.

Occupants of these buildings — office and factory workers,

apartment and condo residents — are all very sensitive to failures

of the water distribution system. People get upset if their hot water

for showers and baths are intermittent or totally run out because

people on other floors use up the available allocation of heated


What happens when hot water does not immediately start flowing?

People let the water run until the flow heats up — potentially

wasting a great deal of water as well as the energy required to

pump and distribute the water.

In addition, consistent water pressure is a must for correct

operations of appliances like dishwashers and laundry machines

as well as for industrial and manufacturing machinery.

The challenge to improve the mechanics of building water

distribution systems is driven by two fundamental needs: firstly,

the need to increase efficiency, and in doing so, decrease water

wastage; and secondly, to improve the reliability of the installed

systems, thereby reducing the ongoing cost of maintenance and



Old technology pumps in large industrial water systems typically

use pressure switches calibrated to switch the pump on if the water

pressure falls to below a specific point (say, below 50 psi) and off

if the pressure exceeds a given parameter (for example, 70 psi).

This operation is fine up to a point, but it essentially means that the

pump is either working at full speed or not at all, and these surges

in demand placed upon a mechanical system may lead to problems

8 Alabama Contractor • • Fall 2019

with reliability and repair. Although undoubtedly rugged and

reliable, the industrial systems of old also tended to be expensive

and inefficient.


Therefore, pump and water system designers have looked for

alternative solutions. First amongst them are the new Variable

Speed Pumps (VSP).

VSPs use a Variable Frequency Drive (VFD) or Variable Speed

Drive (VSD) to continuously optimize the pump speed and power

consumption while maintaining constant outlet pressure of the

pump. In such scenarios, pressure sensors are essential. A pressure

sensor converts the outlet pressure to an electrical signal, which

the VFD uses to adjust the pump’s speed and is either included as

an integral part of the pump design or mounted externally as part

of a total solution.

Similarly, in many cases, a high cut-out pressure switch is

mounted to prevent the pump from outputting extreme pressure.

An additional pressure sensor can also be mounted on the inlet of

the pump to monitor efficiency.


The benefits of pressure sensors in Variable Speed Pump design

can be categorized into three key areas: efficiency, reliability and

the user experience:

Efficiency — Pumps that utilize VSDs in conjunction with

pressure sensors to maintain constant pressure output are proven

to be more efficient. Indeed, in tests, they are proven to be up to

30% more efficient than “traditional” technologies (Hydraulic

Institute, Europump, & U.S. Department of Energy, 2004).

Reliability — VSPs often run at lower speeds and do not run on

an outdated “stop/start” cycle, therefore there is less stress on the

pump, which results in greater reliability, a longer life cycle and

less downtime. This in turn means a lower cost of maintenance.

User Experience — The efficiency and reliability of a VSP

ultimately translates into an improved customer experience. Even

in the more challenging environments, such as high-rise buildings,

a constant, reliable water pressure can be maintained. Beyond the

undoubted benefit of a more reliable water supply, customers

are also able to easily modify the pressure supply (depending on

load and preference). The digital nature of the technology also

allows for greater connectivity with the Internet of Things (IoT),

effectively making the pump an intelligent device providing key

data that can be acted upon in the event that a problem is identified,

such as a burst pipe or leak, or to determine water usage. By using

IoT connectivity, building managers can remotely monitor and

regulate water use, as well as respond in an emergency by either

turning the water systems off to reduce spillage, or by allocating

the highest water press to combating emergencies, such as fighting

fires on the higher levels of a building.


Traditionally, VSPs have been used in larger, commercial and/or

industrial applications, given the previously high costs involved.

As costs have come down, and designs improved (notably the cost

and size of electronics in the VFD and VSD), VSPs have become

affordable in more mainstream, residential applications.

Using variable speed drives with

pressure sensors and switches to

optimize pump speed and power

consumption while maintaining

constant outlet pressure increases

system efficiency while reducing

maintenance costs in residential

water booster pump installations.

Fall 2019 • • Alabama Contractor 9

As the cost of components and pumps becomes more affordable,

variable speed pumps are being used to increase the efficiency and

reliability of water distribution systems in multistory buildings.

This growth has been driven not simply by falling costs but,

more importantly, by rising demand. Increasing urbanization

on a global scale, often combined with a less than consistent

municipal water supply, and power supply mandates, means that

the effective delivery of water is a very real challenge. This in

turn has prompted the sensor manufacturers to innovate.

It is notoriously difficult to maintain a constant water pressure

to every story of a high-rise building, but this is again where

the new generation of pumps and sensors come into their own,

replacing the inefficient and inconsistent “traditional” approach

to water provision via a rooftop water reservoir.

Sensors can detect variations in water pressure to determine when

the pump needs to work a little harder to maintain a constant

pressure and when it can relieve the pressure, but without the

extremes of being either fully “off” or fully “on.” Pumps work

more efficiently if they are run at a constant rate; they are also

less prone to failure, with all of the associated costs of ongoing

repair and maintenance.


Sensata has a range of sensors for use in industrial pumps where

components require rugged, industrial housings. For example,

its 60/70CP range pressure sensors are proven for use in other

industries that require the reliable pumping of liquids, such as

oil, and with a very high degree of reliability (10 million cycle

lifespan). They are also robust enough to withstand potentially

damaging phenomenon such as pressure spikes and hydraulic


As well as the proven 60/70CP sensors, Sensata has recently

launched a cost-efficient pressure sensor family (116CP/126CP),

for smaller residential booster pumps. The patented 116CP/126CP

sensor design is derived from highly reliable and proven

automotive grade pressure sensing technology. The sensors’

innovative plastic housing has options for use in drinking water

applications and makes them ideal for residential and other lower

cost pump applications

The pressure sensor converts the pressure signal into an electronic

value, which the pump VFP uses to control or maintain the output

pressure. The sensor measurement pressure value is usually

presented on the pump’s display, and in some cases, customers

are able to view and monitor pressures via an application on their

smartphone or tablet. In addition, a notification can alert users of

irregularities and assist in preventative maintenance.

The world’s water systems are in desperate need of improvement

— especially as the world’s water resources continue to shrink.

Many have predicted, with the advent of global warming and

climate change — that access to clean, potable water will be the

most critical element of life in the next century. Anything we can

do to improve overall water distribution efficiency and reduce

waste, will be of benefit as the world’s population continues to

grow and migrate in response to changing climates and rising

ocean levels.

Companies like Sensata, who are developing and implementing

new technology water pumps and pressure sensors, will play a

crucial role in the design of residential and commercial solutions

that drive system efficiency and reliability and help to reduce

waste while improving the user experience.

Daniel Mullen is a product line manager at Sensata Technologies

where he leads the product strategy and roadmap for pressure

and temperature sensors for the global industrial, HVAC and

The Environmental Protection Agency’s (EPA) Residential Air

Cleaners, a new technical summary report recently released, is

sure to bring increased awareness to the contractor community

and end-users regarding ozone.

The EPA’s 75-page, comprehensive document (www.epa.

gov/iaq EPA 402-F-09-002) on the strategies, advantages and

disadvantages of all residential air cleaner methodologies

has gone on record and stated that ozone-generating models

are detrimental to homeowners’ respiratory tracts, lungs and

general health.

Prior to the EPA document’s release, the American Society

of Heating, Refrigerating and Air-Conditioning Engineers

(ASHRAE) had already taken a similar position on ozonegenerating

air cleaners and their detriment to occupant health.

ASHRAE’s 2015 publication “Position Document on Filtration

and Air Cleaning” states in Section 2.6, “Ozone is harmful

for health and exposure to ozone creates risk for a variety

of symptoms and diseases associated with the respiratory

tract; ozone emission is thus undesirable.” Section 3.2 of the

document further states, “Devices that use the reactivity of

ozone for the purpose of cleaning the air should not be used

in occupied spaces because of negative health effects that arise

from exposure to ozone and its reaction products.”

Electrostatic Precipitators, Ionizers and Ozone

The EPA has stated that electrostatic precipitators (ESP) and

ionizers, which are air cleaning devices positioned in the

airstream of HVAC systems, as potential contributors to ozone.

Both methodologies use a powered electrostatic process to

charge particles, which become attracted to oppositely charged

plates or other indoor surfaces to remove airborne particulates.

According to the EPA report, “Because ESPs and ionizers use

high voltage to generate ionized fields, they may produce ozone

either as a byproduct or by design. Ozone is a lung irritant that

poses risks to health.”

The report also states that “some makes, and models of ESPs

and ionizers can increase indoor ozone concentrations that can

even exceed public health standards.”

Some designs of another popular air cleaner methodology,

ultraviolet lamp systems, may also intentionally produce ozone

by design. For example, some manufacturers purposefully

use specific UV wavelengths that create ozone to produce the

distinct ozone odor. The air cleaners are either installed in the

supply ductwork or the HVAC system plenum for airstream

disinfection or near the cooling coil to also prevent mold and

other biological growth.

Still, other organizations have carved out regulatory ozone

requirements for consumers. For example, the U.S. Food

and Drug Administration (FDA) was the first to set an ozone

emissions limit of 0.05 ppm (50 ppb) for all medical devices.

In 2008, the California Air Resources Board (CARB) targeted

ozone emissions with a state-wide regulation requiring

certification of all electronic air cleaners under UL 867’s test

standard of 0.05 ppm (50 ppb) limit.

The media prominence of the EPA will help Residential Air

Cleaners garner significant consumer attention in the coming

months among HVAC service contractor customers. Therefore,

contractors should be prepared to discuss ozone and how

products they are providing may or may not be producing

ozone as a primary function or as a byproduct.

12 Alabama Contractor • • Fall 2019

There is no doubt ultraviolet lamp systems disinfect biological

contaminants, according to equipment that passes two UVGI

effectiveness test standards, ANSI/ASHRAE Standard 185.1

for UVGI lamps in in-duct airstream irradiation; and ANCI/

ASHRAE Standard 185.2 for UVGI lamps for in-duct surface


Whether or not a UVGI lamp generates ozone

however, is dependent upon its wavelength. Both

UVA 315-400 nanometer (nm) and UVC 100-

280 nm are used in UVGI air cleaners to

deactivate microorganism reproduction by

altering their DNA structure. Uncoated

UVC lamps at or above 254-nm do not

generate ozone, whereas uncoated lamps

with wavelengths below 254-nm can

generate ozone through photolysis of

oxygen and further reaction, according

to the EPA report.

While the EPA’s report raises a red flag

on ozone potential in residential UVGI

air cleaners, it does not distinguish

what brands and models emit harmful

ozone. That raises questions for

HVAC contractors who are aware that

some brands may or may not generate

ozone to provide their customers with

IAQ solutions and may do more harm

than good.

Furthermore, many air cleaner

manufacturers with designs including

purposeful ozone generation

began substituting their suspected

methodologies with marketing terms that

omit ozone descriptions. For example,

the popular terms 10 years ago were ozone

generator and ozonator, however those

terms are rarely used in air cleaner marketing

materials in light of current ozone findings. This

misguided marketing creates expectant and quite

undesirable marketplace confusion regarding the

amount of ozone generation and off-gassing emissions by

several IAQ technologies, products and brands. Consequently,

consumers and even HVAC contractors, who wanted to install

the safest products, had nowhere to turn for zero ozone emission


UL 2998 Validation for Zero Ozone

Consequently, Underwriters Laboratories (UL),

Northbrook, Illinois, recently took on the task

of creating the desperately needed validation for

zero ozone air cleaning devices. UL 2998 is the

long-awaited environmental claim procedure with

validation. Contractors and consumers can now visit UL SPOT

(, which lists all types of sustainable products

worldwide. The UL SPOT’s “HVAC Air Cleaners” section lists

validated zero ozone products. Qualifying zero ozone emission

products must demonstrate they emit less than the maximum

ozone concentration limit of 0.005 ppm (5 ppb), which is

below quantifiable level for ozone testing. This is 10-

fold less than permitted under test standard UL 867,

which allows concentrations of 0.05 ppm (50 ppb).

Approved products also receive a validation

badge that can be displayed on marketing

materials and product labels.

Although the EPA report targets residential

systems, contractors should be aware that

commercial air cleaning devices can also

come under scrutiny. Consequently,

specifying a zero ozone device may

be the difference between winning

and losing bids, especially when

facility design teams recognize

their importance. Zero ozone air

treatment device specifications may

also someday be required by green

building design projects. Zero ozone

air cleaning device mandates may

someday be required by programs,

such as Leadership in Energy and

Environmental Design (LEED®),

General Services Administration

(GSA) Advantage, the Collaborative

for High Performance Schools (CHPS),

the International Green Construction

Code (IgCC) and European Union

guidelines and directives.

HVAC contractors can be assured ozone

discussions will inevitably arise from

customers who read the many reports that are

surfacing in the media on the dangers of ozone

emissions. It would be prudent for contractors

to prepare their service people with the factual

answers based on the research and refer customers to

sources, such as the UL SPOT, where they will find a list of

validated air cleaning devices that provide air purification with

zero ozone emissions.

Aaron Engel is vice president of business development at Fresh-

Aire UV (, North America’s

largest manufacturer of residential, commercial

and medical UV disinfection and carbon/titanium /

PCO-based air purification systems. Fresh-Aire UV’s

APCO air treatment system recently earned UL 2998

validation for emitting zero ozone. Engel can be

Grease interceptor is an overall term. It is a product category much

like “faucets.” In actual practice there are many different designs

but there are two basic design principles that are used for separating

the FOG (fats, oils and grease) from the wastewater. There has been

confusion over the years in that both designs have been referred to

as grease interceptors.

In 2006 a consensus of the industry specifiers and plumbing officials

with the leadership of IAPMO designated new names for these two

types of grease interceptors — hydromechanical grease interceptor

and gravity grease interceptor.

The hydromechanical grease interceptor incorporates air entrapment,

the buoyancy of grease in water and hydro mechanical separation

with interior baffling for FOG separation. Hydromechanical grease

interceptors continuously separate the FOG at the velocity it enters

the interceptor.

The gravity grease interceptor incorporates two or more

compartments in series, a minimum volume of 300 gallons and

uses its larger volume of water to slow the flow velocity down,

allowing the time required for the buoyancy of FOG in water to

cause separation. That is why the physical size of the gravity grease

interceptor is greater than the physical size of the hydromechanical

grease interceptor.

With both design types the key to proper sizing is understanding the

“size” nomenclature since it is different for each type.

In plumbing valves, piping and fixtures, it is common to size a

product by its inlet connection pipe size. This, however, is not true

with either type of grease interceptor. The size of hydromechanical

grease interceptors is expressed in the gallons per minute flow

(GPM) that the grease interceptor can accept and still remove 90%

plus of the FOG from the influent. The common sizes available

today are 10, 15, 20, 25, 35, 50, 75, and 100 GPM.

The size of a gravity grease interceptor is based on the actual volume

of water the interceptor will hold expressed in gallons. Common

sizes available today are 300, 500, 750, 1,000, 1,250, 1,500, 2,000,

3,000 gallons.

Ever though the designs differ in separation methods and size

nomenclature, the system parameter that must be known for proper

sizing is the same. That parameter is the expected maximum flow in

GPM that the grease interceptor will receive.

With the flow determined, hydromechanical grease interceptor

sizing is very straightforward. You match the calculated flow

in GPM to the size on the interceptor, which is marked in GPM.

Hydromechanical grease interceptors, like most plumbing devices,

are performance-tested to national standards. The standards for

hydromechanical grease interceptors are PDI G101 and ASME

A112.14.3. The hydromechanical grease interceptors are tested at

their rated flow, which is their size designation. For example, a 20

GPM size is tested with a 20 GPM flow of grease-laden water. With

an expected maximum flow of 20 GPM, you would use a 20 GPM

size interceptor.

To size a gravity grease interceptor with the flow determined in

GPM, you multiply the flow number by a detention time of 30

minutes (the time period normally excepted for the grease to

separate by buoyancy). With our 20 GPM example, the size would

be 20 x 30 = 600. A 600-gallon size interceptor would be used.

The sizing methods are rarely disputed. The difference of opinion

is in determining the GPM flow that the grease interceptor should

be sized to handle. When the actual grease producing fixtures are

known, one school of thought is to calculate the total GPM based

on the total of all the volumes of the fixtures draining in one minute,

plus the total of other fixtures that have a designed flow rate. This

would be the peak flow rate for the facility.

The other school of thought is to use DFUs (drainage fixture

units) assigned to each fixture by the plumbing code and use what

16 Alabama Contractor • • Fall 2019

would be an average flow rate. Sizing to potential peak flow rate

will work for both types of grease interceptors. Sizing to DFUs

for hydromechanical grease interceptors can result in peak flows

beyond the size chosen and result in extended drain down time for

fixtures. But since the hydromechanical grease interceptor has a

vented flow control, the designed flow will not be exceeded, and

the FOG removal efficiency will not be compromised although

increased drain down times may be unrealistic and unworkable in

a busy kitchen.

Gravity grease interceptors sized with DFUs could see peak flow

in excess of the sizing, resulting in a decrease in detention time. At

some point, reducing detention time will affect and decrease grease

separation efficiency.

The other challenge in sizing a grease interceptor is the facilities

where the actual fixtures are not known. This can happen in a build

out at a mall where the square footage is designated for a restaurant,

but the type is not known and there is a potential to change

restaurants in the future. Grease interceptors are often required to

be incorporated in the basic building before occupancy is known.

All that may be known at this point to size the interceptor is the

drainpipe size that will discharge to the grease interceptor.

Again, there are two schools of thought for determining expected

flow in GPM, which is needed to size either type of grease


The Plumbing and Drainage

Institute (PDI) is an association

of manufacturers of engineered

plumbing products in a business

area commonly referred to

by the mechanical side of the

construction industry as “the

drain business.”

Our objective is to promote the advancement of Engineered

Plumbing Products through publicity, public relations, research

and standardization of product requirements, as well as to prepare,

edit and publish Standards relating to plumbing products and to

provide certified testing, rating and installation procedures for

Grease Interceptors and Water Hammer Arresters in Standards

PDI-G101 and PDI-WH201 respectively.

PDI maintains testing equipment in independent testing laboratories

for the purpose of testing Water Hammer Arresters for compliance

with Standard PDI-WH201 and Grease Interceptors for compliance

with Standard PDI-G101. Certified Products carry the Seal of the

Plumbing & Drainage Institute as evidence that the product has

met the specified requirements of the Institute’s Standards.

PDI also works to develop National Standards through the American

Society of Mechanical Engineers, ASME A-112 Committee. We also

participate in the development of the model plumbing codes with

IAPMO, International Association of Plumbing and Mechanical

Officials and ICC, International Code Council.

The first school of thought is that the maximum flow would be a full

pipe with gravity flow. Based on standard engineering calculations,

full flow, ¼ pitch, by gravity would approximately be 20 GPM for a

2-inch pipe; 60 GPM for a 3-inch pipe; 125 GPM for a 4-inch pipe;

203 GPM for a 5-inch pipe; and 375 GPM for a 6-inch pipe.

The second school of thought is that in a properly designed drainage

system the pipe will never be more than 50% of full capacity. When

using the first school of thought, both types of grease interceptors will

perform properly — neither one will be undersized. Using the second

school of thought, if flows do exceed 50%, the hydromechanical

grease interceptor will control the flow so grease separation is not

compromised, but fixture drain down time will be extended. If flows

exceed the 50% with the gravity grease interceptor, retention time

will be decreased reducing grease removal efficiency.

Is bigger better? Not necessarily. At one time gravity grease

interceptors were sized by both flow and expected retained solids,

which made them larger needing less frequent cleaning. Actual

field experience has now shown that oversizing can result in the

generation of hydrogen sulfide gas and sulfuric acid, destroying the

interceptor and drainage system.

So there is no pat answer for grease interceptor sizing. Sound

engineering judgment should be applied to each system design.

As a new school year begins, a survey of

9th to 12th graders reveals that unclean

school restrooms cause them to have a

negative perception of their institution

and its leaders. Of those surveyed, 68%

say school restrooms that are poorly

maintained or unclean show the school

doesn’t care about its students, reflects

poor school management

and lowers their overall

opinion of the school.

In fact, nearly half of

students describe the

condition of their school

restrooms as poor or fair.

The findings are part

of the Healthy Hand-

Washing Survey

conducted by Bradley

Corp. The research

asked students across

the country about their

school restrooms and

hand-washing habits.

“The negative impact of

poorly maintained school restrooms is

clearly significant and spreads beyond

the bathroom doors to the entire school,”

said Jon Dommisse, director of strategy

and corporate development for Bradley

Corp. “Female students are even more

inclined to be negatively influenced by

run-down school restrooms.”

The state of a school restroom likely

factors into a student’s decision on

whether to visit the restroom. While

most (81%) use their school restroom

daily, 19% claim to never frequent it.

They avoid the facilities in part because

they’re dirty, smelly or have broken or

old toilets, sinks and doors.

18 Alabama Contractor • • Fall 2019

Outside of schools, restroom conditions

in public businesses also influence

high school students’ perceptions and

preferences. Most students (62%) have

frequented a business based on its

cleaner, well-maintained restrooms.

Similarly, 64% of adults show

preferential treatment for businesses

with pleasant restrooms.


Students do have suggestions for school

restroom improvements. Their number

one request is more privacy. They’d like

taller stall doors and want gaps between

the stall panels eliminated. Their second

wish is for cleaner facilities followed by

more air fresheners. When asked what

bothers them the most about school

restrooms, foul odors top the list.

If students do encounter an unclean or

unpleasant restroom, they usually skip

their trip. More than half say they leave

without using the restroom and 39%

try to avoid using that restroom in the

future. Just 20% take action to address

the situation by notifying a teacher or

school management.

In contrast, the Healthy Hand-Washing

Survey found that when adults are faced

with an unpleasant restroom, their first

course of action is to alert management

(43%). Just 26% of adults choose to exit

without using the facilities as opposed to

the 52% of students who do so.

Avoiding Germs in School Restrooms

Germs in school restrooms are another

hot topic. Students believe the germiest

surfaces are toilet flushers, the floor

around the toilet and stall door handles.

Students back up their beliefs with

actions — 46% operate the toilet flusher

with their foot in order reduce their

contact with germs and 33% use a paper

towel to open the door. Females are

significantly more likely to use these

germ-avoidance strategies in restrooms.

And, even though most schools don’t

post hand-washing reminders, they

might consider it — 57 % of students

say they’d be more likely to wash if

there was a sign in the restroom.

The Healthy Hand-Washing Survey

by Bradley Corp. was conducted

online Jan. 3-8, 2019, and queried 630

American students enrolled in 9th-12th

grade. Participants were from around the

country and were evenly split between

males and females (49 and 51%).
