Chlorine is shipped in Department of Transportation specification steel
containers; standard sizes contain either 100 or 150 pounds of chlorine.
In the cylinder the chlorine has both a liquid and a gas phase. All
cylinders are equipped with the Chlorine Institute standard chlorine
cylinder valve.
Chlorine is a "hazardous material" subject to Department of Transportation
requirements. When used for swimming pool/spa disinfection, chlorine is
considered a pesticide and as such is subject to pertinent regulations of
the U.S. Environmental Protection Agency.
Users of chlorine must be trained as to the proper procedures for handling
chlorine and as to appropriate emergency procedures. Detailed information
is available from chlorine suppliers and the Chlorine Institute, 2001 L
Street, N.W., Washington, D.C. 20036.
2 EQUIPMENT AND INSTALLATION
2.1 Chlorination equipment should be located so that an equipment failure--
or malfunction will have minimum effect on evacuation of swimming pool/spt
patrons in an emergency.
2.2 Elemental chlorine feeders (chlorinators) should be activated by a
booster pump using recirculated water supplied via the recirculation
system. The booster pump should be interlocked to the filter pump to
prevent feeding of chlorine when the recirculation pump is not running.
2.3 The chlorinator, cylinders of chlorine and associated equipment should
be housed in a reasonably gas-tight and corrosion-resistant housing having
a floor area adequate for the purpose. Cylinders should always be stored
in an upright position and properly secured.
2.4 Ail enclosures should be located at or above ground level. The
enclosure should be provided with: ducts from the bottom of the enclosure
to atmosphere in a nonrestricted area, a motor-driven exhaust fan capable
of producing at least one air change per minute, and louvers of good design
near the top of the enclosure for admitting fresh air. Warning signs
should be posted on the doors. It is recommended that the doors to the
chlorine room should open away from the pool.
2.5 Electrical switches for the control of artificial lighting and
ventilation should be on the outside of the enclosure adjacent to the door.
2.6 Contents of a chlorine cylinder can be determined only by weight;
therefore, facilities should include a scale suitable for weighing the
52
~c¥1inders. Changing cylinder(s) should be accomplished only after weighing
:oves contents of cylinder to be exhausted. Care must be taken to prevent
~ter suck-back into cylinder when empty by closing the cylinder valve.
2.7 Connections from the cylinders to the system depend on the type of
chlorinator to be used and should comply with the chlorinator
manufacturer's recommendation.
2.8 It is recommended that an automatic chlorine leak detector and alarm
be installed in the chlorinator room.
2.9 Respirators approved by the National Institute of Occupational Safety
and Health (NIOSH) should be provided for protection against chlorine. It
is recommended that at least one approved self-contained breathing
apparatus be provided. Respiratory equipment should be mounted outside the
chlorine enclosure. Occupational Safety and Health Administration (OSHA)
regulations require training and maintenance programs for respirators.
2.10 Containers may be stored indoors or outdoors. Full and empty
cylinders should be segregated and appropriately tagged. Storage
conditions should: (a) minimize external corrosion, (b) be clean and free
of trash, (c) not be near an elevator or ventilation system, (d) be away
from elevated temperatures or heat sources.
3 OPEI~ATIONAL PROCEDURES
specific person should be made responsible for chlorination
~erations and should be trained in the performance of routine operations
_.,cluding emergency procedures and leak control procedures.
3.2 Chlorine cylinders must be handled with care. Valve protection caps
and valve outlet caps should be in place at all times except when the
cylinder is connected from falling objects. Cylinder should be used on a
first-in, first-out basis. New, approved washers should be used each time
a cylinder is connected.
3.3 It is recommended that a safety wall chart be posted in or near the
chlorine enclosure and a second chart in the swimming pool/spa office near
the telephone. Such charts are available from many suppliers and from the
Chlorine Institute, 2001 L Street, N.W., Washington, D.C. 20036. The
telephone number of the chlorine supplier should be shown on this chart.
3.4 Although chlorine suppliers make every effort to furnish chlorine
properly-conditioned cylinders, chlorine gas leaks may still occur.
Swimming pool/spa personnel should be informed about leak control
procedures and consideration should be given to providing a Chlorine
Institute Emergency Kit A.
in
3.5 Chlorine suppliers are equipped with a Chlorine Institute Emergency
Kit A, which contains devices for capping leaks at cylinder valves and some
A~aks which occur in the cylinder wall. Further information on these kits
id training slides demonstrating their use are available from the Chlorine
~stitute.
53
3.6 As soon as a container is empty, the valve should be closed and the
lines disconnected. The outlet cap should be applied promptly and the
valve protection hood attached. The open end of the disconnected line
should be plugged or capped promptly to keep atmospheric moisture out of
the system.
3.7 To find a chlorine gas leak, use a plastic bottle containing 26° BE
Ammonia capable of releasing only vapors when squeezed. A white cloud will
result if there is any chlorine leakage. Never use water on a chlorine
leak.
For additional information, contact the Chlorine Institute, Inc., 2001 L
Street, N.W., Washington, D.C. 20036 (202) 775-2790, and request a copy of
the "Chlorine Manual" and the wall chart entitled "Handling Chlorine
Cylinders & Ton Containers".

1.1 Swimming Pool and Spa Temperature Controls
(a) Ail pool and spa heaters shall be equipped with an ON-OFF switch
mounted for easy access to allow the heater to be shut off without
adjusting the thermostat setting and to allow restarting without relighting
the pilot light.
Ail gas and oil-fired pool heaters when tested in accordance with the
Standard RS-30 shall have a minimum thermal efficiency of 78%.
(b) Spas and heated swimming pools shall be equipped with a cover designed
to minimize heat loss. EXCEPTION: Outdoor pools deriving over 20% of the
energy for heating from non-depletable on site-recovered sources computed
over an operating season are exempt from this requirement.
(c) Time clocks shall be installed on private pools so that the pump can
be set to run during off-peak electric demand periods and can be set for
the minimum time necessary to maintain the water in a clear and sanitary
condition in keeping with applicable health standards. EXCEPTION: Pumps
connected to swimming pool solar water heating systems or any pool legally
r~Dnsidered a public pool.
2 Hot Water Pipe Insulation
In residential water heating systems, piping insulation is required only
for recirculating systems. For recirculating systems, piping heat loss
shall be limited to a maximum of 17.5 Btu/h per linear foot of pipe, in
accordance with Table 9-7B, which is based on a design external temperature
not lower than 65°F. Piping loss at other design temperatures must be
calculated. EXCEPTION: Piping insulation is not required when the heat
loss of the piping, without insulation, does not increase the annual energy
requirement of the building.
