Fire Suppression Systems
I. Exterior Combination Water Service Overview /Major System
Components:
It was determined from the original (03-01-03) fire suppression
installing contractors shop drawings that the 8 underground fire
main and 4 domestic water main originate on the north side of this
building, northwest of the paved entry and near Woodruff Avenue.
There is an existing yard valve/box at this location.
This 8 ductile iron fire main is routed eastward, turns slightly
southeastward and then enters the basement level, Mechanical Room
No. 120M between columns no. 08 and 09 at column no. 28.
Also at this location is the 3-way fire pump test header TC1.
Reference attached Site Utility Plan, FS1, and field photos No. 3
and 4.
Design and Operating Conditions:
A flow test was performed by the installing contractor on
03-20-03 at 12:00am and the recorded performance resulted in the
following design criteria:
o Static pressure ______________ 108 PSI o Residual pressure
____________ 102 PSI o Flow ______________________ 1566 GPM o Pitot
_______________________ 87 PSI
This test occurred at the two nearest (Woodruff Avenue) fire
hydrants approximately 500 lineal feet west of the local 20 water
main.
System Description and Interface to Other Systems:
The 8 fire service is sized to support all of the various fire
sprinkler systems within this facility.
This single source supplies the buildings fire pump assembly,
standpipes, fire department hose valves, fire hose stations, the
wet pipe and the dry pipe systems throughout.
Sequence of Operation:
The 8 interior fire service and its dedicated individual
sub-systems are all automatic in function. The jockey pump JP
maintains system pressure while these systems are in a
static/non-event mode as might occur during small leaks. The fire
pump provides operating pressure during a fire event. The
standpipes (2-1/2 Class I fire hose valves) are utilized by fire
department personnel to combat fire with heavy hose streams. The
wet pipe sprinkler system operates strictly on the fusing or burst
of a typical sprinkler head. The dry pipe sprinkler also relies on
the fusing or burst of a typical sprinkler head which relieves air
from the piping network. An air-compressor is used to maintain air
pressure in this piping under normal conditions.

Upon evacuation of this pipe air, this triggers the system dry
pipe valve to allow the introduction of water to the point of
rupture/fire. Integrated supervisory attachments in each system
trigger respective alarms.
Safety Considerations/Operation and Maintenance,
Troubleshooting, System Analysis and Recommendations:
Verification of the functionality of the 8 fire service main
isolation/yard valve nearest the takeoff from the local street main
would be recommended. Replacement of the valve box access cover
with a labeled Fire or a label familiar to the authority having
jurisdiction (AHJ) would enhance identification of the correct
shut-off valve. In addition, it would be highly recommended to have
a current fire flow test performed and recorded with the university
and the AHJ noting changes from the original design.

II. Interior Fire Service Overview/Major System Components:
The 8 fire main runs approximately 10 lineal feet southwest and
drops to an 8 horizontally mounted double check detector DCA
assembly. The outlet rises and continues on to the fire pump
suction inlet. Reference field photo Nos. 1 and 2 in appendix.
Design Operating Conditions and System Description:
The interior 8 schedule 40, black steel pipe is grooved end with
cast style fittings and mechanical couplings. This is true from 8
size through 2-1/2 size pipe. From 2 size through 1 size, piping
remains schedule 40, black steel, but with cast style fitting and
threaded joints. This size line is capable of flowing a theoretical
2500 GPM with a 10.0 PSI pressure drop per 100 lineal feet at the
specified 15 FPS maximum limitation. This is well beyond the system
designed (750 GPM) requirement based on hydraulic calculations and
NFPA code requirements. The 8 double check backflow device
performance at 750 GPM flow is 5 PSI pressure drop.
System Interface with Other Systems:
The interior fire service beginning at the exterior fire service
entry ends in the basement level, Mechanical Room No. 120M/Fire
Pump Room.
Safety Considerations:
It may be advisable to contain or protect the 8 double check
detector assembly from physical damage as this is the life line to
the fire pump and also a very costly component of the system.
This backflow device (630 lbs) rests on the installed pipe
elbows, which in turn rest on pipe stands. Service clearance for
maintenance/testing should be maintained.
Operation and Maintenance, Troubleshooting, Analysis and
Recommendations:
The backflow device requires minimal maintenance although a
semi-annual overall check should be performed to ensure no internal
debris or external leaks exist. Recertification of the device is
required following service.

III. Fire Pump Assembly Installation Overview and Major System
Components:
The fire pump assembly consists of the following componentry: o
Vertical, in-line centrifugal fire pump FP o Vertical, multi-stage
centrifugal, close coupled jockey pump JP o Fire pump controller
FPC o Jockey pump controller JPC o Inlet/outlet pressure gauges o
Supervisory shut-off valves, check valves, relief valves and drain
valves o Automatic (power) transfer switch ATS o Low suction
cut-off panel LSCP. o Fire department connection FDC o Fire pump
test header TC1
These pumps, FP and JP are both supported on threaded hanger
rods which are imbedded in small, 4 high concrete housekeeping
bases achieving approximately 9 A.F.F. mounting height. The
discharge pipe is supported from the structure above on threaded
rods with swivel ring hangers. The fire pump test header line is
supported with hangers from the discharge piping.
Reference field photos Nos. 4, 6, 7, 8, 9, 10, 11, 12, and 13 in
appendix and attached fire pump piping schematic FS1 and flow test
data listed in Section I, Exterior Combination Water Service,
Design and Operating Conditions.
Design and Operating Conditions:
This fire pump is an electric driven field fabricated assembly
meeting the UL listing and NFPA 20 standards for centrifugal fire
pump installation. The fire pump FP component is an ITT-AC company
model, no. 1580 with a 40HP, vertical in-line pump and 3550 RPM
motor powered by 480 volt, 3 phase, 60 HZ and 52 full load amps.
The motor is a US Electric Company, open drip proof model no.
AD27A/286 JPY frame with class F rating and 1.15 service factor.
The pumps capacity is 750 GPM at 60 PSI (138.6 FT. HD).
The jockey pump JP is a Goulds Pumps Company, SSV series, model
No. VM3545 with a 1HP, vertical multi-stage pump and 3500 RPM motor
powered by 240 volt, 3 phase, 60 HZ and 3.6 full load Amps. The
motor is a Baldor Company, totally enclosed fan cooled, model no.
VM-3545/56C Frame with Class B rating and 1.25 service factor. The
pumps capacity is 10GPM at 70 PSI (161.7 FT HD).
System Description, Interface with Other Systems and Sequence of
Operation:
The existing fire pump assembly is a field fabricated system
comprised of factory assembled, tested and approved components. The
entire installation composes an interactive unit in which the fire
pump FP is static until a catastrophic event occurs. The jockey
pump JP maintains a constant water pressure in the pipe network
during the static mode. Its function is to artificially pressurize
to an elevated level such that if a sprinkler head releases the
pressure differential would quickly be recognized by the

fire pump and avoid false starts due to small leaks. The field
installed pressure sensing lines communicate with the fire pump FP
fire pump controller FPC, automatic transfer switch ATS, the jockey
pump JP, jockey pump controller JPC and the low suction cutoff
panel LSCP for overall operations. The fire pump controller
monitors the assemblys multiple power sources and fire pump per
NFPA 70 for:
o Visual Signals Power availability pilot light Phase reversal
pilot light
o Alarm Signals Motor running Power failure Phase reversal
The automatic transfer switch is an integral part of the fire
pump controller and in the event of loss of primary power it will
switch to the secondary (emergency generator) power supply.
The jockey pump controller monitors the assemblys jockey pump
per NFPA for: o Running period timer o Power availability pilot
light o Motor running pilot light
The low suction cut-off panel monitors the fire service pressure
availability and will shutdown the fire pump assembly if incoming
pressure drops to 20PSI or less over a period of 30 seconds. This
panel monitors per NFPA 70 for:
o Visual signals Power availability pilot light Secondary power
energized pilot light Low suction pressure pilot light
o Alarm signals Power failure Secondary power failure Low
suction pressure (following time delay)
Safety Considerations, Operations and Maintenance:
Pumps o The fire pump and jockey pump shall be observed for
excessive vibration while
running following any routine maintenance and/or repair. o
Follow the manufacturers instructions when dismantling, repairing
and
reassembling. o Always use the complete model number and serial
number when ordering parts. o Maintain clearance space around this
equipment for service needs for the
manufacturers recommendations. o Controllers/panels/devices
-
Evaluation of Fire Suppression Systems for the Ohio State
University Physical Sciences Research Building July 9, 2008
7 | P a g e
o All control components should be observed for tightness of
electric connections, and the absence of any short circuits, ground
faults or current leakage.
o In addition, be certain enclosures are properly closed and
sealed prior to energizing breakers or switches.
o Follow the manufacturers instructions when dismantling,
repairing and reassembling
o Always use the complete model number and serial number when
ordering parts. o Maintain clearance space around this equipment
for service needs per NFPA 70.
Valves/Fittings: o All such shall be observed for leakage and
proper (open/closed) position. o Follow the manufacturers
instructions when dismantling, repairing and
reassembling o Always use the complete model number and serial
number when ordering parts. o Maintain clearance space around this
equipment for service needs per NFPA 70. o Verify that the local 4
floor drain and sewer line in this space are clear, clean
and functional.
System Analysis and Recommendations:
The fire pump assembly was specified as a factory assembled skid
package. The system as installed is a field assembled unit.
It should have been skid mounted and set on an overall concrete
housekeeping pad. Currently, a small pad with small diameter
threaded rod supports.
The power supply and conduit to FP are poured into the base
beneath the pump. Inlet/outlet piping is supported from floor
above. Recommendation would be to install a supporting pipe and
pump structure of
substantial integrity to support the weight of this piping and
pumps.
Where fire pumper line is supported from the bypass line, the
recommendation would be to provide pipe stands and transverse steel
rail for support from the floor.
Reference NFPA 20 for detailed description of test procedures
and the attached maintenance schedule regarding components,
activity and frequency.

IV. Wet Pipe Sprinkler System Overview/major system
components:
The basic design of this system is a hydraulically calculated
system as determined in NFPA 13 Density/Area Curves Figure No.
11.2.3.1.1 and 11.2.3.1.2 Hose Stream Allowance.
All sprinkler piping is schedule 40 black steel with grooved
ends and cast fittings and mechanical couplings on sizes 2-1/2 and
larger. Piping 2 and less is also schedule 40, black steel but with
threaded ends and threaded cast fittings.
The sprinkler head styles vary as determined by application and
they are as follows: o Pendent style (downward trajectory) with
escutcheon in chromed finish, 155
temperature limitation, orifice. o Upright style (upward
trajectory) in standard brass finish, 200 temperature
limitation, orifice. o Concealed pendent style (downward
trajectory) with white ceiling cover plate,
155 temperature limitation, orifice. o Horizontal sidewall style
(horizontal pattern) with white recessed escutcheon
155 temperature limitation, orifice.
Pipe hangers are traditional clevis type suspended from
structure on all threaded rods. Reference the attached basic
wetpipe floor control valve assembly FS2.
Design and Operating Conditions:
The wet pipe sprinkler system is a hydraulically calculated
system based on a combination of Ordinary Hazard Group 1
application with 0.15 GPM over 1,500 sq. ft. minimum area of
operation for all lab areas with a maximum of 130 sq. ft. coverage
per sprinklers and a Light Hazard with 0.1 GPM over 1,500 sq. ft.
minimum area of operation for all office/administrative areas with
a maximum 225 sq. ft. coverage per sprinkler. This is in accordance
with NFPA 13, State and Local Standards. The maximum area of
protection is 52,000 sq. ft. for Light and Ordinary Hazard.
System Description:
The wetpipe sprinkler system is a fixed fire suppression network
of water pressurized piping and closed heat sensitive automatic
sprinkler heads in heated spaces only. These heads are located and
spaced per specific application based on the aforementioned
standards. In a fire event, the affected sprinkler(s) release and
distribute water over the fire to extinguish or control until the
fire brigade arrives. Note, only sprinklers in the immediate fire
area will release thereby minimizing any water damage.
-
Evaluation of Fire Suppression Systems for the Ohio State
University Physical Sciences Research Building July 9, 2008
11 | P a g e
System Interface to Other Systems:
The only interface relative to the wetpipe sprinkler system is
indirect through water flow detecting devices located at the source
of the supply branch to a particular fire zone. This supervisory
device communicates with the building fire alarm, building
automation system and exterior electric alarm bell (if
provided).
Sequence of Operation:
As a fire begins, the ambient temperature rises to the threshold
of the local sprinkler head(s).
As the temperature rises higher, a sprinkler fuses/breaks
causing water to discharge over the fire source.
This flow is recognized by the flow switch on the piping feeding
this zone. The flow switch relays a signal to the addressable fire
alarm with the alarm indication
and its zoned location.
The fire alarm relays the message to the local fire brigade as
well as the building automation system.
Safety Consideration, Operation and Maintenance:
Continued observation of water stained ceilings and or walls
should be taken seriously and reported for signs of pipe, fitting
or valve failure which would affect the system in time of need.
Triggering of false alarms may imply hidden leakage in the
network and should be investigated and repaired.
Sprinkler heads exposed in utility or areas subject to abuse
(whether intentional or not) should be protected with wire
cages.
Piping containing water should never be run in or through a
space which could see freezing temperature even for a short
while.
Troubleshooting:
The best means of trouble shooting a sprinkler system is
accomplished through testing of flow, alarm and possibly water
pressure at regular intervals.
System Analysis and Recommendations:
The entire network should be reviewed indentified in segments
(preferable as they relate to the addressable fire alarm system),
arranged into a service matrix schedule format based on a regular
calendar time frame for the record and documentation should be
maintained.
Reference NFPA 26 for detailed descriptions of test procedures
and the attached maintenance schedule regarding components,
activity, and frequency.

V. Drypipe Sprinkler System Overview/Major System
Components:
The basic design of this system is a hydraulically calculated
system as determined in NFPA 13 Density/Area Curves figure No.
11.2.3.1.1. and 11.2.3.1.2, Hose Stream Allowance. In addition,
Section 11.2.3.2.5 increases the area of operation by a 30% margin
without an increase in density.
All sprinkler piping is schedule 40, galvanized steel with
grooved ends and galvanized fittings and mechanical couplings on
sizes 2-1/2 and larger. Piping 2 and less is also schedule 40,
galvanized steel but with threaded ends and threaded galvanized

These sprinkler heads are limited to a maximum 130 sq. ft. area
of coverage in accordance with NFPA 13, State and Local
standards.
The sprinkler head count is 37 total in this area with: o 4
pendent type o 33 upright type
The air compressor maximum capacity is 290 gallons volume output
in 30 minutes at 40 PSI, pump on setting is 30 PSI off is 40
PSI.
System Description:
The drypipe sprinkler system is a modified version of a wetpipe
system in that it is water based but the water is held back on the
inlet side of the drypipe valve. Downstream of this valve, the
piping is pressurized with compressed air from the base mounted air
compressor. It is this compressed air that holds the drypipe valve
closed. The pipe network includes closed heat sensitive sprinkler
heads. This type of system is normally employed only in areas which
may be subject to freezing conditions.
These heads are located and spaced per specific application
based on the aforementioned standards. In a fire event, the
affected sprinkler(s) release and allow the air in this piping to
escape. Upon reduction in pipe pressure the drypipe valve opens and
allows water to fill the piping and distribute water over the fire
to extinguish or control until the fire brigade arrives. Again,
note that only sprinklers in the immediate fire area will release,
thereby minimizing any water damage.
There is a 1 inspectors test station from the drypipe network
exiting the southwest corner wall (near columns no. 3/L15) to the
exterior on grade.

System Interface to Other Systems:
The drypipe sprinkler system interfaces directly with the local
air compressor, building fire alarm, electric alarm bell (if
provided) and building automation systems through integral
supervisory devices.
Sequence of Operation:
As a fire begins, the ambient temperature rises to the threshold
of the local sprinkler head(s).
As the temperature rises higher a sprinkler fuses/breaks causing
the loss of air pressure contained within the piping.
This loss of pressure allows the drypipe valve to open causing
water to quickly flow into the pipe network.
This loss of air pressure is recognized by the supervisory
device (pressure switch) and relays the signal to the addressable
building fire alarm with the alarm indication and its zoned
location.
When water reaches the open sprinkler head, it discharges over
the fire source. The fire alarm relays the message to the local
fire brigade as well as the building
automation system. Safety Consideration, Operation and
Maintenance:
Sprinkler heads in this network located in utility spaces on
spaces with no ceiling should be installed with wire cages to avoid
accidental breakage.
Continued observation for the beginning of pipe/fitting leakage
should be taken seriously and reported and repaired prior to major
water damaged occurring.
Frequent cycling of the air compressor may imply a small but
growing air loss issue. Troubleshooting:
The best means of troubleshooting this sprinkler system can be
accomplished through monitoring and testing of flow alarm and air
pressure at regular intervals.
System Analysis and Recommendations:
Reference NFPA 26 for detailed descriptions of test procedures
and the attached maintenance schedule regarding components,
activity and frequency.

VI. Standpipe System Overview/Major System Components:
The automatic wetpipe, Class I standpipe systems in this
building are primarily composed of a 6 vertical stack riser,
continuous from lowest to highest floor level which serves various
fire hose valves throughout. The standpipes (3 total), two (2) of
which are located in enclosed stairways (west zones) originating in
Stair No. X143S and Stair No. X140S (north and south) and one (1)
is enclosed in an interior shaft (east zone). These standpipes also
supply the entire wetpipe sprinkler network. A floor control
assembly consisting of a supervised floor control valve, electric
flow switch and inspectors test station (with drain) is installed
near the ceiling of each floor level in each zone. This assembly
FCV1 supplies the sprinkler main to that respective floor zone.
There are three distinct standpipes in this building. They all
originate in the basement level and all are 4 in size.
Reference appendix field photos Nos. 19, 20, 21, 22 and attached
schematics FS4, FS5, and FS6.
Design and Operating Conditions:
The minimum flow rate of this hydraulically designed system is
500 GPM for the most remote standpipe and 250 GPM for each
additional standpipe located in a required exit stairway. In this
case (2 total) 750 GPM.
The minimum pressure requirement is 100 PSI at the hydraulically
most remote 2-1/2 hose connection.
By code (NFPA 14), it is not necessary to add the sprinkler
demand to a building which is protected throughout by an automatic
sprinkler system.
The standpipe system main drain for a 4 size or larger standpipe
is a maximum of 2 size.
The water flow minimum duration requirement for a Class I system
is 30 minutes. System Description:
The standpipes are schedule 40, black steel with grooved ends
and mechanical couplings.
The standpipe isolation valves are electronically supervised
type, horizontal butterfly valves with grooved mechanical
couplings.
The floor control assembly serving each floor/zone is composed
of an electronically supervised type horizontal butterfly valve
with grooved/mechanical couplings, an electronic vane type flow
switch with time delay and an inspection test and drain with globe
valve, drain port and sight glass window.
The hose valve cabinet stations located in the stairwells are
recessed, fire rated enclosures with 2-1/2 rough chromed angle type
globe valves installed on a 15 angle downward including chained
caps. The cabinets are white enamel painted steel with

duo-glass and steel panel doors. The cabinets are lockable and
also have large external identification labels.
The hose valve cabinet stations located throughout the building
are primarily recessed, fire rated enclosures with 2-1/2 rough
chrome, angle type globe valve installed on a 15 angle downward
including chained caps and also including a 10 lb. ABC fire
extinguisher. The cabinets are white enamel painted steel with
duo-glass and steel panel doors. A few locations have surface
mounted cabinets. All cabinets are lockable and have large external
identification labels.
System Interface to Other Systems:
The standpipe system interfaces with the building fire alarm and
building automation system through the supervisory attachments
(i.e. flow switch and tamper switch) at the main isolation valve
and floor control valve assemblies.
Sequence of Operation:
If the main isolation valve(s) or floor control valve(s) are
closed, an alarm is signaled at the fire alarm/building automation
stations.
If flow is detected at the flow switch(es) in the floor control
assemblies, an alarm signal is conveyed to the fire alarm/building
automation stations.
When an alarm arrives at the fire alarm station it is also
relayed to the fire brigade. Safety Considerations:
All supervised valves and attachments should be installed in
occupied spaces at an elevation above and out of reach of occupants
to preclude vandalism.
Operation and Maintenance Issues:
All valves and attachments should be observed on a regular basis
to ensure their integrity and functionality.
Maintain accurate records of fire extinguisher maintenance
and/or replacements. System Analysis and Recommendations:
Reference NFPA 26 for a detailed description of test procedures
and the attached maintenance schedule regarding components,
activity and frequency.

Safety Considerations:
-
Evaluation of Fire Suppression Systems for the Ohio State
University Physical Sciences Research Building July 9, 2008
26 | P a g e
The CAES disbursing agent poses no threat to software and
hardware because it does not break down to any damaging acidic
byproducts. This clean agent has been tested on computers and
electrical switchgear and has proven to cause no harm. Oxygen
content is reduced to the 10-13% range (normal air is 21%), but the
addition of carbon dioxide counteracts the risk of low oxygen
content to humans. The combination of 10% oxygen and 4% carbon
dioxide results in the equivalent of oxygen contained in breathing
air with 21% oxygen. Since Inergen is composed of naturally
occurring gases, it poses no adverse effect to the environment. Its
ozone depletion potential, global warming, potential thermal
decomposition by-products and atmospheric lifetime ratings are all
zero.
Operation and Maintenance Issues:
The CAES system should be tested semiannually as well as
thoroughly inspecting all components for proper operation by a
trained and competent service company. All tests and reports should
be recorded and documented for the owners records. Both clean agent
quantity and pressure should be verified on each cylinder. If
either a 5% loss of weight or 10% loss of pressure is evident,
refill or replacement should occur. If the amount of agent is
determined other than by weight, the testing equipment must be
listed/approved and documented as well. This information should
also be attached to each cylinder.
Inspection of cylinders that have been inoperative for a period
of 5 years should receive a thorough visual inspection per CGA
pamphlet C-6 directives. If any cylinder shows signs of physical
damage further strength tests shall be performed. Inspection of the
protected environment should also occur on at least a semi-annual
basis. This is determined if the protected space sealed envelope
has been violated with added barrier penetrations. If visual
inspection reveals an inability to contain clean agent discharge
these issues must be corrected and where any uncertainty is
involved, the space should be tested for containment integrity.
This also includes the entire area beneath the raised floor. All
system piping should be hydrostatically tested for a period of 10
minutes at 150-psig and no more than 20% pressure drop is allowed.
Pressure should be applied in 50-psig increments. When an actual
discharge test is performed, all cylinders shall be weighted prior
to and following discharge. Verify environment volumes(s) and
compare to recorded design data. An allowance for HVAC shutdown and
damper closure should be considered.

All related field circuitry should be measured for ground fault
and short circuit conditions. This should involve removal of all
detection devices and provision of jumpers to complete these
circuits for testing and subsequent device reinstallation.
Verification that the power source is from a dedicated, reliable
and uninterruptable source should be confirmed and documented.
Auxiliary alarms, displays, annunciations and de-energizing
equipment/devices should be checked for proper operation, including
interface relays to the building automation system and remote
monitoring station. As defined in NFPA, Clean Agents are
electrically non-conductive gases, which do not leave residue after
evaporation.
Troubleshooting System Analysis and Recommendations:
Provide additional emergency breathing apparatus in Room No.
4175 Perform all testing indicated herein and provide record
document for the owners
records
In lieu of a discharge dump test, perform a room pressurization
test by an approved company if acceptable to the authority having
jurisdiction

SECTION 2. PLUMBING: Sanitary Waste and Vent System
2.1 Overview
The sanitary waste and vent system is the basic building system
for means of removing wastewater from the building back to the
building sewer and on to a wastewater treatment facility. The
system is connected to plumbing fixtures throughout the building
which includes water closets, urinals, lavatories, sinks, floor
drains, etc.
The sanitary waste system for the ground through fourth floor is
a gravity system and the basement level has a duplex sewage
ejector. The sewage ejector serves the plumbing fixtures on the
basement level and pumps the wastewater to the gravity sanitary
sewer on the ground level. The duplex sewage ejector is located in
the basement level mechanical room 120M.
Duplex Sewage Ejector SE-1
Zoeller Pump Co. model G6284 (two (2) pumps)
Capacity: 64 GPM at 27 ft. hd. (each pump)
H.P., 460 volt, 3 phase
3 discharge
Electrical power from motor control center EMCCI
Reference: Plumbing Equipment Schedule on drawing P3.01 and
detail F on drawing P4.01.
Duplex Sewage Ejector SE-1
2.2 Design Conditions
Not applicable for this system.
2.3 Systems Interface to Other Systems
The sanitary waste and vent system does not interface with any
other system and the effluent from the building sanitary system
connects to the site sanitary sewer.
2.4 Operations and Maintenance Considerations
The sanitary waste and vent system should require minimum
maintenance. Plumbing fixtures and trim should be inspected one (1)
time a year for proper operation and leaks. Fixture traps should be
checked for proper water seal and floor drains with trap primers
should be verified for proper operation.

2007-81021 OSU System Description
-
The duplex sewage ejector pumps should be checked four (4) times
a year for proper operation. The sump pit level controls should be
verified for proper control. Listen for proper check valve
operations. Check for even operating times on duplex pumps. Uneven
times indicate a defective unit, float switch or control. Once a
year the sump basin should be inspected and cleaned.
2.5 Safety Considerations
Shut-off electrical power supply before servicing submersible
sewage pumps. Submersible pumps contain oils which becomes
pressurized and hot under operating conditions and 2.5 hours should
be allowed after disconnecting electrical power before attempting
pump service.
The primary safety considerations are to prevent unexpected
energization or startup of motors, and the release of hazardous
energy, including steam, during service or maintenance
activities.
The guidelines for both the proper electrical lock-out/tag-out
procedures and for preventing the accidental release of steam
should be implemented and included in the training program for all
personnel involved in servicing this equipment. The accepted
standards as defined by OSHA for these safety procedures is CFR
1910.147, which is in the appendix of this report and available at
this web site:
http://www.osha.gov/SLTC/controlhazardousenergy/index.html.
Additionally, the University should maintain and follow safety
procedures in accordance with the state and federal guidelines as
adopted by the Public Employee Risk Reduction Act (Ohio Revised
Code 4167.07).

Water Served with 1-1/2" domestic cold water line thru 1-1/2"
backflow preventer.
Safety Water System Served with 2 domestic cold water line.
3.4 Operations and Maintenance Considerations
The duplex booster pump should be checked four (4) times a year
for proper operation. Check for even operating times on duplex
pumps. Check for pump noise and vibration and determine if noise is
in motor or pump. If noise is in the motor check for bearing
problem and check motor/pump alignment. If noise is in the pump
verify that the valves on the suction side of the pump are open to
prevent cavitation. Check pump bearings and mechanical seals.
All reduced pressure backflow preventers should be inspected and
tested two (2) times a year. A differential pressure gauge of the
type recommended by the valve manufacturer should be used for
testing. Local code requires the building water service backflow
preventer to be inspected and tested once year by a certified
inspector.
The safety water system and thermostatic mixing valve is served
from the domestic C.W. system that serves the basement through
second floor level. The safety water system serves the entire
building and the system pressure should be checked on the fourth
floor level.
3.5 Safety Considerations
The primary safety considerations are to prevent unexpected
energization or startup of motors, and the release of hazardous
energy, including steam, during service or maintenance
activities.
The guidelines for both the proper electrical lock-out/tag-out
procedures and for preventing the accidental release of steam

SECTION 4. PLUMBING: Domestic Hot Water System
4.1 Overview
Domestic hot water is supplied throughout the building. System
consists of two (2) steam-to-hot water converters located in the
basement level mechanical room 120M. Domestic water heater WTH-1
serves hot water to the basement, ground and second floors and
domestic water heater WTH-2 serves the third and fourth floors. A
hot water return loop for each heater along with an in-line return
pump on each system circulates water throughout the building in
order to maintain system temperature. Domestic hot water return
loop circulating pumps are identified as RCP-1 and RCP-2.
Water Heaters No. WTH-1 and WTH-2 (See photo below.)
Reco model no. HXV150-G-635SS-SPNS.
Semi-instantaneous quick recovery heater.
770 gph of 40F to 140F. water when supplied with 15 psi steam

H.W. Return Loop Circulating
Pumps RCP-1 and RCP-2 Thermostatic Master Mixing Valve
4.2 Design Conditions
The domestic hot water systems are designed for 110F. outlet
water temperature. The maximum expected water flow is 38 GPM at 20
psi system pressure drop for each system.
4.3 System Interface to Other Systems
The domestic water heater is provided with steam from the
re-boiler. There is one re-boiler; therefore, there is not back-up
for the steam supply to the water heaters and the downtime for
servicing the re-boiler will need to be coordinated with the
building needs since hot water will not be available.
Hot water return loop circulating pumps RCP-1 and RCP-2 are not
connected to the emergency generator system.
4.4 Operation and Maintenance Considerations
It shall be noted that although there are two domestic water
heaters it is not a redundant system. The water heaters serve
different floors of the building. Since only one heater serves each
system it is important that the units be inspected and serviced
four (4) times a year to avoid unexpected shutdowns.
The thermostatic mixing valves should be inspected four (4)
times a year for leaks and the proper temperature regulation. Once
a year the valves should be serviced and the port sleeve/bridge
cleaned and the packing and gaskets replaced.
4.5 Safety Considerations
The primary safety considerations are to prevent unexpected
energization or startup of motors, and the release of hazardous
energy, including steam, during service or maintenance
activities.
The guidelines for both the proper electrical lock-out/tag-out
procedures and for preventing the accidental release of steam
should be implemented and included in the training program for all
personnel involved in servicing this equipment. The accepted
