(ix) The flume's structural design and materials shall be in accord with accepted structural engineering practices and shall provide a durable structure that will safely sustain all weights and pressures (dead load, live load, liquid, hydrostatic and earth pressures) for the expected operating life of the structure. The flume shall be watertight and the surface shall be inert, nontoxic, smooth and easy to clean. The flume shall be designed or ventilated, or both, to prevent a possible hazardous concentration of toxic disinfectant fumes.
(b) Walkways:
(i) A four foot (1.22m) minimum width walkway, walkway steps or a stairway shall be provided between the plunge pool and the top of the flume.
(ii) Walkways and steps shall be well drained, slip resistant, separated from the flume by a physical barrier
and set back far enough from the operating flume so that users do not touch them while traversing the flume.
(c) Pump reservoirs: The pump reservoirs shall have sufficient volume to contain at least two minutes of combined flow from all water treatment and flume pumps and enough water to insure that the plunge pool will maintain a constant water depth.
(d) Mats:
(i) Flexible or plastic foam used to traverse the flume shall be stored dry and shall be wiped or soaked daily prior to dry storage in or with one of the following sanitizing solutions:
(A) 50-200 ppm of free chlorine. (B) 12.5-25 ppm of titratable iodine; or (C) 200 ppm of quaternary ammonium.
(e) Attendants:
(i) An attendant shall be provided at the plunge pool and at the top of the flume.
