The operator or their designee shall demonstrate knowledge to the department or its agent on the pool’s interlock system in all the following areas: ATCP 76.13(1)(c)2.a.a. Describes the location of chemical feed connections and system flow sensing interlocks in the recirculation system. P ATCP 76.13(1)(c)2.e.e. Describes what safety measures that must be employed during monthly testing. P ATCP 76.13(1)(c)3.3. Once monthly, challenge testing of the chemical feeder system shall be conducted to assess the interlock pursuant to subd. 1. P ATCP 76.13(1)(c)4.4. A log of the monthly test shall be kept and meet all of the following: ATCP 76.13(1)(c)4.a.a. Documented with the date, results, and the name of the person performing the test. P ATCP 76.13(1)(c)5.5. The system flow sensing interlock requirement does not apply to pools constructed before February 2009, unless the pool has been involved in a chemical release incident in which the installation of a flow sensing interlock would have prevented the chemical release. ATCP 76.13(2)(a)(a) Maintenance hazards. All maintenance that presents a danger to the patrons, including changing chlorine gas tanks and testing interlocks, shall be performed when the pool is not in use or is closed to public use. P ATCP 76.13(2)(b)(b) Maintenance signage. When access to a pool or pool area cannot be restricted, signage shall be in place indicating that the pool is closed, and the area shall be monitored to ensure the pool is not in use. This would include a pool area that contains more than one pool, but not all of the pools are closed. This applies to hotels with pools built before February 1, 2017, with access to the pool area through the guest room. P ATCP 76.13(3)(3) Repairs. Only personnel trained and licensed in handling gas chlorine by a certifying agency such as the federal occupational health and safety administration may repair gas chlorinators. Pf ATCP 76.13(4)(4) Evacuation during chemical feed incident. If the interlock is activated stopping flow from the chemical feeders, or the water recirculation pump is stopped manually or unexpectedly for any reason and duration, including power outages, all patrons shall be evacuated from the pool until manual evaluation of the cause for interlock activation or recirculation pump interruption is completed by the responsible supervisor or pool operator.
