Louisiana Administrative Code › Title 51 - PUBLIC HEALTH-SANITARY CODE › Part XIV - Plumbing › Chapter 13 - Medical Facilities Plumbing Systems [formerly Appendix G - Medical Facilities Plumbing Systems] › Section XIV-1305 - Drainage and Venting

Current through Register Vol. 50, No. 6, June 20, 2024
A. Ice
				Storage Chest Drains. Any drain serving an ice storage chest or box shall
				discharge over an indirect waste receptor separate from all other fixture
				wastes. Each terminal shall discharge through an air gap (drainage system)
				above the receptor. The end shall be covered with a removable screen of not
				less than 10 mesh per square inch (15.5 mesh per 1000 sq mm), and if
				discharging vertically, the terminal shall be cut at an angle of 45° (0.785
				rad).
B. Bedpan Washers and
				Clinical Sinks. Bedpan washers and clinical sinks shall be connected to the
				soil pipe system and vented following the requirements as applied to water
				closets, except that bedpan washers require additional local vents.
C. Sterilizer Wastes. Wastes for sterilizers
				shall conform with the following.
1. Indirect
				Wastes Required. All sterilizers shall be provided with individual and separate
				indirect wastes, with air gaps (drainage system) of not less than two diameters
				of the waste tailpiece. The upper rim of the receptor, funnel, or basket type
				waste fitting shall be not less than 2 inches (51 mm) below the vessel or
				piping, whichever is lower. Except as provided in Paragraphs 2 and 4 below of
				§1305 C, a "P" trap shall be installed on the discharge side of, and
				immediately below, the indirect waste connection serving each
				sterilizer.
2. Recess Room Floor
				Drain. Floor drains in a room or area where the sterilizer is recessed shall
				conform with the following.
a. In all recess
				rooms containing the recessed or concealed portions of sterilizers, not less
				than one acceptable floor drain, connecting to the drainage system, shall be
				installed in a manner to drain the entire floor area.
b. The recess room floor drain waste and trap
				shall be a minimum 3-inch (76 mm) diameter. It shall receive the drainage from
				at least one sterilizer within the recess room to assure maintenance of the
				floor drain trap seal. The sterilizer drain shall be installed on a branch
				taken off between the floor drain trap and the drain head. An individual waste
				trap shall not be required on this type of installation.
3. Prohibited Connections. Branch funnel and
				branch basket type fittings, except as provided in §1305. C.4 of this code
				below, are prohibited on any new installation or when relocating existing
				equipment. Existing branch funnel or branch basket type installations shall be
				provided with an acceptable indirect waste below the branch
				connections.
4. Battery Assemblies.
				A battery assembly of not more than three sterilizer wastes may drain to one
				trap, provided the trap and waste are sized according to the combined fixture
				unit rating, the trap is located immediately below one of the indirect waste
				connections, the developed distance of a branch does not exceed 8 feet (2438
				mm), and the branches change direction through a tee-wye or wye pattern
				fitting.
5. Bedpan Steamers,
				Additional Trap Required. A trap with a minimum seal of 3 inches (76 mm) shall
				be provided in a bedpan steamer drain located between the fixture and the
				indirect waste connection.
6.
				Pressure Sterilizer. Except when an exhaust condenser is used, a pressure
				sterilizer chamber drain may be connected to the exhaust drip tube before
				terminating at the indirect waste connection. If a vapor trap is used, it shall
				be designed and installed to prevent moisture being aspirated into the
				sterilizer chamber. The jacket steam condensate return, if not connected to a
				gravity steam condensate return, shall be separately and indirectly wasted. If
				necessary to cool a high temperature discharge, a cooling receiver, trapped on
				its discharge side, may serve as the fixture trap.
7. Pressure Sterilizer Exhaust Condensers.
				The drain from the condenser shall be installed with an indirect waste as
				prescribed in this Part. If condensers are used on pressure sterilizers, the
				chamber drain shall have a separate indirect waste connection.
8. Water Sterilizer. All water sterilizer
				drains, including tank, valve leakage, condenser, filter and cooling, shall be
				installed with indirect waste and according to §1305. C.2.a of this
				code.
9. Pressure Instrument
				Washer-Sterilizer. The pressure instrument washer-sterilizer chamber drain and
				overflow may be interconnected. Also, they may be interconnected with the
				condensers. The indirect waste shall follow the provision set forth in this
				Part.
