CPO Thursdays: The CPO Test

0:00
welcome to thursday my name is rudy
0:02
stankowitz i'm one of the co-hosts of
0:04
the talking pools podcast but i'm also
0:06
the ceo and president of aquatic
0:08
facility training and consultants i'm a
0:11
cpo instructor an afo instructor as well
0:14
as a consultant a few other things
0:16
that's what i want this thursday show to
0:18
be about i want to talk about those
0:20
certification programs i want to discuss
0:22
the material that's in those programs
0:26
i'm going to call it pool operator talk
0:28
if you need to renew your pool operator
0:30
certification take a look at these
0:32
podcasts view them as a refresher
0:34
they'll be fabulous for that if you've
0:37
never taken the cpo program before the
0:39
cpo certification class or the afo
0:42
certification class take a look at these
0:45
as your prep
0:46
not looking to get your certification
0:48
not a problem these episodes on pool
0:51
operator talk are going to be super
0:53
beneficial anyway a great refresher for
0:56
the pro if you have new hires or if you
0:59
are new to the pool industry there's
1:01
going to be a lot of education in here
1:02
that you don't want to miss prep
1:03
materials on my website that's
1:05
cpoclass.com
1:07
so if you're interested in flashcards
1:10
practice tests some other video
1:11
exercises go there check it out
1:14
cpoclass.com
1:16
hit the tab that says practice test
1:18
you'll find that information there in a
1:20
minute we're going to dive into the
1:22
program i'll see you there
1:25
[Music]
1:32
i wanted to start with just talking
1:35
about the program itself initially you
1:37
don't have to be an expert to come into
1:39
the course you're not going to leave the
1:40
course an expert unless you were already
1:42
an expert when you came in what makes
1:45
you an expert is the years of experience
1:48
out in the field a two-day class is not
1:51
gonna do it
1:53
so don't put that stress on yourself but
1:56
definitely don't leave the course
1:57
thinking that you know everything either
1:59
because you don't
2:00
so
2:01
don't be afraid to ask for help
2:05
i like to make myself available to my
2:07
certification students to my in either
2:09
class going forward should any questions
2:12
ever arise because i don't think two
2:14
days and see you later is enough to help
2:16
somebody get started
2:18
in their career
2:20
whether you're working for somebody or
2:22
operating your own company
2:25
it's just not
2:26
you will run into things that you
2:28
haven't seen before you will forget
2:29
things that you heard in class
2:32
i let everybody know right then and
2:34
there
2:35
hit me up with an email best way to get
2:37
me rudy cpo class dot com easy peasy
2:41
send me an email if there's some way
2:42
that i can help you i will happily do
2:44
that emails work fantastic because you
2:47
can attach a picture
2:48
so i can see what you see
2:51
and that can also benefit both of us and
2:53
help me diagnose whatever you got going
2:55
on a little bit quicker if i can help
2:56
you out
2:59
i've also done some face time tours of
3:01
pools for my cpo students after the fact
3:04
so uh we're we like we like to stick
3:07
around you know we look at this as a
3:08
relationship not one and done and i
3:10
think that's important because i think
3:12
coming into a new industry or even if
3:14
you know what if you've been in the
3:15
industry for a long long time a second
3:17
set of eyes doesn't hurt and we like to
3:20
be that for you now
3:22
the program itself does go through
3:25
everything
3:26
maintaining a commercial or a public
3:28
pool
3:29
the same things can be applied to a
3:31
residential pool there is no reason why
3:33
you should not apply this education to a
3:35
residential pool because a swimming pool
3:37
is a swimming pool the only difference
3:39
between a residential pool and a
3:41
commercial pool is the size of the pool
3:43
the amount of people that swim in it and
3:44
of course the equipment
3:46
and we'll talk about that stuff too
3:48
maybe not in this episode right off the
3:49
bat
3:50
but
3:52
in a future episode
3:55
first things first i like to start with
3:57
the end in mind
3:59
so ultimately the second day of this
4:01
course the second half of the second day
4:03
of this course there's going to be a
4:04
test
4:05
sometimes tests can cause some anxiety
4:08
for folks
4:11
i hope to quell that a little bit
4:13
because there's really nothing to be
4:14
anxious about
4:16
this test that you're going to take
4:19
it's 50 questions long
4:21
all multiple choice
4:23
a b c or d
4:25
even the math a b c or d it is an open
4:28
book test you can use the book you can
4:31
use any handouts your instructor gives
4:33
to you you can use any notes that you
4:35
take i like to take the notes in the
4:38
margins in the book that way i have them
4:41
forever if i take notes on a pad of
4:43
paper i'm surely going to lose those at
4:45
some point in time and yes you know what
4:47
i want them available for this test
4:50
but it would be nice to have them going
4:52
forward so if i write them in the
4:54
margins in the book that is absolutely
4:56
the best way to ensure that i will still
4:58
have that stuff i wrote down
5:00
something i picked up from class that i
5:02
thought was interesting going into the
5:04
future
5:05
so you're allowed to use that the book
5:08
handouts notes you're allowed to use a
5:10
calculator make sure you bring one of
5:12
those not a bad idea to bring a
5:14
highlighter and some post-it flags so
5:16
you can post pages so things are easy to
5:18
find
5:19
so 50 questions three hours to take the
5:22
test that's 10 less questions than you
5:25
had if you took the class five six years
5:27
ago it's also 30 minutes longer now
5:30
because it used to be two and a half
5:32
hours now you have the three hours to
5:33
take the test
5:35
pretty cool
5:36
so you get to spend more time with each
5:38
question than the way the course used to
5:40
be set up
5:41
on this 50 question test
5:44
you have to get 37 questions correct in
5:46
order to meet the requirements of the
5:48
program
5:49
37 questions which means you can get 13
5:52
wrong or only 10
5:54
questions that involve any type of math
5:56
whatsoever
5:58
just 10.
5:59
that's it
6:01
are you following me here
6:03
so if you have to get 37 right that
6:05
means you can get 13 wrong there's only
6:07
10 math that means you could completely
6:10
blow every single math question
6:13
and still do okay
6:15
it's not a good plan but it can be done
6:18
if you can find everything else you need
6:20
in the book 40 questions in the book and
6:22
get the right answer for those you could
6:24
theoretically completely blow every
6:26
single math question and do okay that's
6:28
not what we want i want you to do well
6:30
on the math the math is super important
6:32
in the pool industry so i'm not trying
6:34
to minimize that either
6:36
everything we do everything you do going
6:39
forward
6:41
is going to involve math this course
6:42
itself as you go through it it's going
6:44
to seem entirely heavy heavy math
6:47
that's why i like to head it off this
6:49
way first and let you know hey there's
6:51
only 10 math questions and if you can
6:53
find everything else in the book
6:55
don't stress the math the goal is the
6:58
more you go forward in your career and
7:00
you run into these different things you
7:02
refer back to book then you commit those
7:04
things to memory but you're going to
7:06
need it for calculating bather load
7:08
gallons dosing equipment sizing
7:11
you name it it's just going to be a lot
7:13
of math involved in this career for you
7:16
but don't stress it because you'll be
7:18
able to go back to the book
7:21
or the handouts your instructor gave you
7:22
whichever
7:24
like i said this is why it's good to
7:25
write everything down in the book it's
7:27
easy to find the book pieces of paper
7:29
not so much but you can go back to the
7:31
book the formulas will be there all you
7:33
have to do is identify the correct
7:35
formula and it'll click hey you know
7:37
what yeah we went over that in class i
7:39
know it's in the book maybe you don't
7:41
remember it right off the top of your
7:42
head but you know it's there and you
7:44
know that you can find it
7:45
so that's super important so
7:48
50 questions three hours to take the
7:50
test only ten questions that are math
7:53
and you don't need to stress them
7:55
now let's talk about the books okay
7:57
make sure that you find the index in the
8:00
book i know page 295 and the cpo
8:02
handbook is the index that's the most
8:04
important page in the book i do not
8:06
remember off the top of my head which
8:07
page the index is in the afo book but it
8:10
does have one and in this great index
8:12
mark those pages in some way shape or
8:14
form so that they're easy to find if you
8:17
have to look up the answer to 40
8:19
questions in a book
8:20
it's important to know where the index
8:22
is
8:25
now
8:26
how much you learn and how much you
8:28
retain from these classes that you
8:30
attend
8:31
is heavily instructor driven
8:34
it depends on how the course is taught
8:38
it depends upon the skill set of that
8:40
instructor
8:42
i personally the big thing for me is not
8:45
that piece of paper with a certificate
8:48
on it that's not the most important
8:51
thing for me although i do want you to
8:53
get it don't get me wrong the most
8:55
important thing to me is that you learn
8:58
and that you still remember that stuff
9:00
six months later
9:02
so i try to set my classes up and i
9:04
think i do a pretty good job
9:06
for
9:08
the purpose of retention
9:10
i do a lot of hands-on i do a lot of
9:12
visual i do a lot of demonstrations not
9:15
everybody does and that's fine the way i
9:17
look at it is you do you but my goal
9:20
coming into this is i all decided i
9:22
wanted to be the teacher i always wanted
9:25
to have
9:28
so that's the way that i teach
9:30
now getting back to this book looking at
9:32
the index sometimes you have to look for
9:35
variations of what you're searching for
9:39
for example
9:40
we know if somebody poops in the pool
9:42
a solid stool
9:44
the big threat there is giardia
9:47
that's the thing that you can get from a
9:49
human solid stool that is the hardest to
9:51
kill it's a protozoa
9:53
so when somebody poops in the pool
9:56
first thing you do
9:58
everybody out of the water get out of
10:00
the pool remember roy scheider in the
10:02
movie jaws on the beach with a bullhorn
10:04
get out of the pool
10:07
or get out of the water whatever anyway
10:09
get everybody out of the pool get them
10:11
off the deck get them out of the gated
10:13
area and lock that gate if you leave
10:15
them milling about the pool area they're
10:17
definitely going to try to get back into
10:18
the water i've seen it a million times
10:20
well i was floating over there so can i
10:23
swim over there no
10:26
it's disgusting
10:29
the next thing you do you got to scoop
10:30
the poop and when you scoop it out what
10:32
do you do with it you fling it over the
10:33
fence into the neighbor's yard because
10:35
you don't like them no you can't do that
10:37
you need to dispose of it in a means in
10:39
accordance to the local sanitation
10:41
department they're going to tell you to
10:43
either flush it or bag it and toss it in
10:46
a waste pail same as if you were picking
10:48
up after your dog walking your dog you
10:49
gotta pick the poop up
10:51
bag it throw it in the garbage or flush
10:53
it it's just poop okay so with a solid
10:56
stool the next step we throw our poop
10:58
scooping equipment into the pool because
11:00
our equipment has to go through the same
11:02
process that the water goes through in
11:03
order to sanitize it correctly
11:06
then we raise our chlorine level up to
11:08
two
11:09
parts per million and you hold it there
11:11
for 25 minutes
11:14
i want my ph to be 7.5 or lower the
11:17
reason i want my ph at 7.5 or lower is
11:20
because chlorine's effectiveness is ph
11:22
dependent
11:23
the lower the ph the more effective my
11:25
chlorine is at 7.5 50 effective at 7.2
11:30
it's 66 effective and it actually gets
11:32
more effective from there
11:35
so when i say 7.5 or lower essentially
11:37
what i'm telling you is about my
11:39
chlorine to be 50 effective or better
11:42
the name of the chemical that we use to
11:44
test ph
11:45
phenyl
11:46
red
11:48
phenol red it's easy to remember because
11:50
it starts with ph it's spelled p h e n o
11:55
l and it's red
11:56
phenol red and what sound does ph make
12:00
right
12:02
okay
12:03
so
12:05
after 25 minutes
12:08
what do you do
12:10
let him swim
12:12
diarrhea
12:14
sometimes it's running
12:17
the beginning steps are pretty much the
12:19
same
12:20
close the pool get the people out of the
12:21
water get them off the gate out of the
12:23
deck area lock the gates scoop what you
12:25
can you got to scoop the chunks i had
12:27
one student call it chasing the corn
12:32
but you got to scoop out what you can
12:33
and again we disposed of it
12:35
in accordance with the local sanitation
12:37
department we're going to either flush
12:38
it or bag it and toss it in a waste pail
12:42
the dumpster to the trash bin whatever
12:45
following that hoop scooping equipment
12:47
goes back into the pool
12:49
now
12:50
we're going to raise our chlorine level
12:52
up to 20
12:54
parts per million
12:56
20 parts per million
12:58
how do you know that you got there
13:02
how do you know that you've successfully
13:04
obtained a chlorine level of 20 parts
13:06
per million
13:10
i know you got to test it right
13:12
but
13:13
the test kit you are using does not
13:16
likely go up to 20 parts per million
13:20
so that drop test that you're using or
13:22
if you're using test strips
13:24
keep in mind you're not allowed to use
13:26
test strips in a commercial pool
13:28
anywhere in the country that has a
13:30
public pool code
13:31
but
13:33
that drop test can only test up to 10
13:34
parts per million of chlorine above that
13:36
it'll bleach out so if you're using a
13:38
drop test and trying to determine
13:40
whether or not you have 20 parts per
13:42
million of chlorine because you're
13:44
trying to treat a diarrhea accident in a
13:47
swimming pool
13:50
you're only guessing
13:52
and now you're playing games with
13:53
people's health and we don't do that
13:56
because you got to keep in mind as you
13:58
go through this program or as you listen
14:00
to me on thursdays
14:03
you'll see that lives are literally at
14:06
stake in what we do
14:08
so we don't want to fudge
14:10
in order to test a chlorine level of 20
14:12
parts per million you're going to need
14:14
to obtain an fas it's foxtrot alpha
14:17
sierra fas dpd means of testing chlorine
14:22
you don't have to get a whole new kit
14:24
if you can you can get a test kit that
14:27
actually comes with that fas method of
14:30
testing chlorine that's the powders in
14:32
there where you count the drops that's a
14:34
titration test counting the drops is a
14:36
titration test the one where you hold up
14:39
the test block to match the colors
14:41
that's called chlorometric that method
14:44
but this is titration
14:47
and like i said it'll go up to 20 parts
14:49
per million which is what we need
14:51
because that's what we got to drive the
14:52
chlorine level up to
14:54
there's this thing known as a ct value
14:56
which is chlorine multiplied by time it
14:58
works out two ten and a half days if you
15:01
had a chlorine level of one part per
15:02
million that's how long it would last in
15:05
the water if somebody had a diarrhea
15:07
accident at a facility that only
15:08
maintained their chlorine level at one
15:10
and nobody noticed it ten and a half
15:12
days anybody who gets water in their
15:14
mouth and swallows it is at risk of
15:17
contracting cryptosporidium that's how
15:20
this is transmitted fecal to oral route
15:23
is what they call it i like to say don't
15:25
drink the butt water because that's what
15:27
a swimming pool is people stick their
15:28
asses in there all day long so guess
15:30
what don't drink the butt water so make
15:33
sure that you have the correct test kit
15:35
i also want my ph to be at 7.5 or lower
15:39
and again as we discussed the name of
15:41
the chemical we use to test ph is called
15:45
phenol red
15:46
again starts with ph
15:50
we're going to hold our chlorine level
15:52
at 20 parts per million for
15:54
12.75 hours
15:56
what do we need to do
16:00
well we had diarrhea in the pool we
16:02
scooped out what we could it must have
16:03
went somewhere
16:06
we need to clean the filters to waste so
16:08
you need to either backwash or clean or
16:10
hose off or however you're cleaning your
16:12
filters you need to clean them
16:13
thoroughly and to waste
16:15
after we've done that
16:17
our chlorine levels been up at 20 parts
16:19
per million we need to bring it down to
16:21
a swimmable level
16:23
and
16:24
what the acceptable range for an outdoor
16:26
pool is one part per million to 10 parts
16:28
per million so we need to bring it down
16:29
to at least 10 parts per million the
16:31
name of the chemical that we use to
16:32
lower chlorine
16:34
is called sodium thiosulfate that's the
16:37
same chemical that's in reagent r
16:40
triplo7 in that drop test that's the one
16:43
with the first one with the green cap
16:44
for the total alkalinity test the
16:45
chlorine neutralizer sodium thiosulfate
16:48
they'd make that available in a large
16:50
quantity in a granule that you could add
16:52
directly to the swimming pool to lower
16:54
the chlorine level
16:56
do not overdo it
16:58
make sure you dose correctly which means
17:01
you need to know exactly where your
17:02
chlorine level is if you add too much
17:06
sodium thiosulfate to the water you're
17:08
going to create one hell of a chlorine
17:10
demand
17:11
that could take a while
17:14
to get used up the sodium thiosulfate it
17:16
tends to linger until it's used up
17:19
before you can maintain a good chlorine
17:20
level again
17:22
so make sure that we don't overdose
17:25
now that we've lowered the chlorine
17:27
level
17:29
we can let them back in the pool again
17:31
except for the little bastard that
17:32
in the pool that kid deserves to be
17:34
punished
17:35
so like i said i like to come up with
17:36
different things to help my students
17:38
remember
17:39
what we went through to increase
17:42
retention and this is no exception so
17:44
for this fecal incident response
17:47
procedure that we just went through
17:49
i decided the best way
17:52
to help you guys remember
17:54
is
17:55
if i was to present it as
17:58
a poem so
18:01
don't grade it too harshly i did this
18:03
with love in my heart i did it for you
18:05
i call it what do you do
18:09
if it's poo
18:11
you ready
18:13
if it's poo
18:15
it's two
18:17
if it's runny
18:19
it's 20
18:21
what do you think right so if it's poo
18:23
it's two two parts per million ph is 7.5
18:27
or lower hold it for 25 minutes if it's
18:29
diarrhea 20 parts per million right if
18:33
it's runny it's 20 20 parts per million
18:35
ph is 7.5 or lower and we're going to
18:38
hold that for 12.75 hours
18:41
if you're a pool service company
18:44
this test kit is worth a lot of money to
18:47
you this 30 test kit check out this
18:50
scenario right hotel pool
18:52
saturday maybe it's a busy saturday
18:54
memorial day weekend
18:56
why not let's call it that busy saturday
18:59
memorial day weekend somebody has a
19:01
diarrhea accident in the pool of the
19:02
hotel
19:03
they shut the pool down
19:06
the guests start complaining they're
19:08
lining up at the counter in the lobby
19:10
demanding a refund demanding free rooms
19:13
and they're giving them to them because
19:15
they want to keep their customers happy
19:17
there's even going to be people in that
19:19
line that had no intention whatsoever of
19:21
getting into those pools
19:23
waiting in line to get that discount
19:26
the engineer picks up the phone calls
19:28
their regular pool service company
19:31
they don't answer
19:33
he leaves a message
19:36
how long do you think he gives them to
19:38
return the call before he starts calling
19:40
other pool service companies that he
19:42
pulled up in a search engine
19:46
15 minutes
19:47
20 minutes
19:49
half an hour
19:51
engineer's desperate he goes to his
19:53
computer he goes into a search engine he
19:55
searches pool service companies in my
19:58
area and gets the list that comes up he
20:01
starts calling everybody on the list
20:03
he's not even leaving messages at this
20:05
point he's just waiting for somebody to
20:07
pick up the phone
20:08
call after call after call finally he
20:11
gets to you
20:13
and you answer
20:15
and he asks you if you're able to handle
20:18
this
20:19
if you do not own an fasdpd means of
20:22
testing chlorine
20:24
you have to say no
20:26
but if you do
20:28
you can say yes
20:29
this sounds like an expensive job right
20:31
because i did say 12.75 hours
20:34
that's a long time and they're gonna pay
20:36
it because they're stuck
20:40
now
20:41
they might not fire their regular pool
20:44
service company that weekend but they
20:46
just got really really close to the edge
20:49
and the next time they screw up they're
20:51
out and don't you think that they're
20:53
going to remember the person that came
20:55
out and saved them
20:57
they're going to call you
20:59
now check this out this hotel also
21:02
happens to be part of a management
21:04
company
21:06
they have 10 other properties within 15
21:08
miles of that location
21:12
the chief engineer goes to the regional
21:14
meeting everybody's talking all the
21:16
other engineers you know everybody in
21:18
their clicks start talking about oh my
21:20
swimming pool is such a pain in the ass
21:22
the water's
21:23
green or is there stuff on the walls
21:25
there's a scum line built up i don't
21:27
even know when my pool service company
21:29
is there
21:30
they're not doing what i want them to do
21:32
don't you think that guy is going to
21:35
recommend you if you've been doing a
21:37
great job at his facility
21:39
he will
21:40
and you might pick up more out of that
21:44
management company like i said 10 other
21:46
properties within 15 miles you might
21:48
pick them all up
21:50
how much of a boost in business would
21:52
that be because you owned a 30 test kit
21:57
don't think that scenario could happen
22:01
an incident i had with one facility from
22:04
a management company resulted in me
22:06
picking up 30 more properties from that
22:07
management company within 12 months
22:11
when i had my service company
22:13
so those things can definitely happen
22:16
it happened to me
22:18
because i answered the phone and i had
22:20
the right equipment
22:23
okay so you're not a pool service
22:25
company you work at the facility your
22:27
on-site staff that test kit is still
22:30
worth a lot of money to you think about
22:33
that line at the counter you know
22:35
they're asking for discounts you know
22:37
they're getting free rooms
22:39
buy the f a s dpd test kit now
22:44
this way you have it when you need it
22:47
you know people only poop in the pool on
22:50
weekends
22:51
that's a fact
22:52
you go down to your pool store guess
22:54
what they don't have this fas
22:57
foxtrot alpha sierra fas dpd test kit in
23:01
stock
23:02
now what
23:04
they have to order it monday they place
23:06
the order that means the earliest
23:08
they're going to get it is tuesday you
23:11
can't start this treatment until you can
23:14
confirm that you have a chlorine level
23:16
of 20 parts per million
23:19
you're adding on time not just hours but
23:22
days even if you went to amazon which we
23:25
should always shop local
23:27
but if you did go to amazon use amazon
23:30
prime that's still two days and then you
23:32
have no idea how old the test solutions
23:35
are that you're getting
23:39
go to your pool store
23:40
now
23:42
order the fasdpd test kit
23:46
bring it back to your facility put it on
23:48
a shelf
23:49
in one of those you know in case of
23:51
emergency brake glass type of scenario
23:53
somebody's butt exploded in the pool and
23:56
the entire thing turned brown
23:58
so now you can start this process right
24:01
away and your pool's only going to be
24:04
closed that 12.75 hours instead of
24:07
having to wait for a test kit to show up
24:10
go to your index in the cpo book this is
24:13
just for the cpo book right at this
24:14
moment and look up f f-a-s-d-p-d
24:21
it's not there
24:23
okay fine f-a-s-d-p-d it's not there
24:26
let's go to dpd see if we can find it
24:29
there
24:30
look for a variation of the word
24:33
still now
24:35
okay
24:36
we know it's a question
24:37
forgive my noise here we know it's a
24:39
question about water testing right the
24:42
fas dpd test kit so grab your book
24:45
flip through the pages
24:48
and i want you to get to the first page
24:50
of the chemical testing section so
24:52
that's chapter eight
24:53
and we're on page 87 actually
24:57
so
24:58
we know it's got to be in here somewhere
25:00
right
25:02
it's got to be in here somewhere i do
25:04
not want you to read the chapter
25:07
three hours is not enough time to read
25:10
this
25:12
book while you're taking that test
25:15
so what i do want you to look at is look
25:18
at
25:19
the tools they gave you you're going to
25:21
see
25:22
that every section within the page has
25:26
different color enlarged font or bold
25:30
print all i want you to do is read those
25:32
things so if we flip through just
25:34
reading
25:37
you'll see test methods for color you
25:39
get the page 94 and there it is boom
25:44
right there on page 94
25:47
fas dpd titration testing everything we
25:51
need to know about this test kit is
25:54
going to be in this section here
25:58
was that hard
26:00
that's on the chance that something's
26:02
not in the index that you need
26:06
use the tools in the book use the
26:08
enlarged font use the bold print
26:11
to find what you need
26:15
do not get stuck on any single word
26:19
so
26:20
that's a basic rundown of how to go
26:22
through this book and a little bit about
26:24
the test and what you can expect during
26:26
the class and again as you go through
26:28
the class it is going to seem like it is
26:30
extremely heavy math but have no fear at
26:33
the end when you take the test you're
26:35
looking at only 10 math questions that
26:37
you don't even have to get correct as
26:39
long as you find everything else in the
26:41
book
26:42
and you can use an index it tells you
26:44
what page to go to all you have to do is
26:47
do that if you hear things that your
26:49
instructor says during the course of the
26:51
program highlight it if you think it's
26:54
going to be important or if you find it
26:56
super interesting either way that's
26:58
going to be beneficial to you going
26:59
forward can you learn a lot in the cpo
27:02
class or the afo class
27:05
yes
27:06
you can
27:07
it's dependent upon you
27:09
and your instructor
