MAHC/ISPSC Consistency Standing Committee Objective • Identify design criteria inconsistencies between the MAHC and

MAHC/ISPSC Consistency Standing Committee Objective • Identify design criteria inconsistencies between the MAHC and the ISPSC, evaluate the most appropriate science/data-based information, and make recommendations for revisions to the MAHC or ISPSC, as appropriate.

Methods: • Committee members to identify inconsistencies between the ISPSC and the MAHC design

Methods: • Committee members to identify inconsistencies between the ISPSC and the MAHC design standards. • For identified inconsistencies: • Determine which code contains the most appropriate, technically accurate information, and/or the best elements from each code • Evaluate science, best practice and potential for performance-based criteria for item • Make recommendations for revisions to either the MAHC, ISPSC, or both so the most appropriate, technically accurate information is included • Include necessary, supporting information, as specified by the respective organization's code update process • Identify individual(s) to prepare, submit and advocate for the proposed code update using the respective code(s) process • Publish alternate viewpoints and rationale whenever decisions are not unanimous, this may include alternate viewpoints considered, but not accepted

International Swimming Pool and Spa Code (ISPSC) – MAHC Consistency Update • October 19,

International Swimming Pool and Spa Code (ISPSC) – MAHC Consistency Update • October 19, 2017 Harmonization Meeting at Denver WAHC • 21 Material inconsistencies identified • 20 Change proposals MAHC Policy > ISPSC • 15 Adopted for 2021 Edition • 5 Not Approved, • ? ? Changes proposal ANSI & ISPSC Policy > MAHC • ? ? Adopted for 2018 MAHC

2021 ISPSC Adoptions to Align with MAHC • Lifts – Listed to UL 60335

2021 ISPSC Adoptions to Align with MAHC • Lifts – Listed to UL 60335 -2 -1000 • Water Velocity – 6 fps suction / 8 fps return – Design flow rate • Induced Air – Disallowed in Pools to prevent obstructed view of bathers in distress – Allowed in Spas and Swim Spas • Chemical Feeders – Listed to NSF 50 • Underwater Lighting – 8 Lamp Lumens, measured at the water’s surface – Standardized method to measure LED output

2021 ISPSC Adoptions to Align with MAHC (Continued 1) • Ladder Clearance – 4”

2021 ISPSC Adoptions to Align with MAHC (Continued 1) • Ladder Clearance – 4” maximum gap behind ladders – Head entrapment, same for barriers and playground equipment • Equipment Storage Rooms – MAHC language adopted • Chemical Storage Space – MAHC language adopted • Indoor Air Quality – MAHC language adopted • Gutter Overflow Systems – 125% of design flow between gutter and collection tank – MAHC language adopted • In-Pool Circulation – MAHC language adopted

2021 ISPSC Adoptions to Align with MAHC (Continued 2) • Outlined Edges – Marker

2021 ISPSC Adoptions to Align with MAHC (Continued 2) • Outlined Edges – Marker tile must be slip resistant • Beach/Sloped Entry – Slip resisting to at least 36 inches • Signage Update – No children under 5, children under 14 required adult supervision, warning for pregnancy and health issue • Underwater Benches – Location restriction and increased minimum size • Interactive Water Play Features – Exact model code language adopted

CMAHC Consistency Proposals • Interior Color • Current – Inspector judgement required – “color…

CMAHC Consistency Proposals • Interior Color • Current – Inspector judgement required – “color… shall not prevent detection of a bather in distress” • Proposed – Performance-based test – “Finishes shall be not less than 6. 5 on the Munsell color value scale” • Ladder Clearance – URGENT • Current – Not less than 3 inches (7. 6 cm) and not more than 6 inches – 4 to 6 inches is the head entrapment hazard! • Proposed – 4” maximum gap behind ladders – Head entrapment, same for barriers and playground equipment

CMAHC Consistency Proposals (Continued 1) • Steps for Depth Transition • Current – Steps

CMAHC Consistency Proposals (Continued 1) • Steps for Depth Transition • Current – Steps between transitions prohibited • Proposed – Allow steps with hand rails – Example from a sun shelf down to shallow end floor – Think giant top step • Maximum Floor Slope – RESEARCH NEEDED • Current – 1: 12 • Proposed – 1: 10 for depths greater than 3 feet. Needed for smaller motel/hotel type pools with extremely limited space

CMAHC Consistency Proposals (Continued 2) • Starting Blocks: Minimum Pool Depth • Current –

CMAHC Consistency Proposals (Continued 2) • Starting Blocks: Minimum Pool Depth • Current – 48 inch depth – reported injuries • Proposed – 60 inch depth – minimum in Canada & ISPSC • Safety Barriers: Minimum Height • Current – 48 inch height • Proposed – 72 inch height • Deck Space Occupancy • Current – 50 SF/Bather • Proposed – 15 SF/Bather

New Issues for Both Codes to Consider • Standardized “NO DIVING” Symbol • In-pool

New Issues for Both Codes to Consider • Standardized “NO DIVING” Symbol • In-pool depth markers: codes require them to be halfway underwater; some say this is a problem • Interactive Water Feature Collection Tanks • Human access for cleaning and service • In-tank skimming • Manual or automatic in-tank floor cleaning, with low-point drain, or clearance for vacuuming • Transition from “PRESCRIPTIVE” to “PURFORMANCE”
