A hotel pool has 3,600 square feet of water surface. How many pool users does the code assume for sizing sanitary facilities?
- a.180 users
- b.240 users✓
- c.120 users
- d.360 users
The code counts one user per 15 square feet, so 3,600 ÷ 15 = 240. The 180 figure uses 20 square feet, 360 uses 10, and 120 uses 30.2025 CBC §3116B.2
What does the capacity sign state for a public pool of 2,000 square feet that is not a spa?
- a.100 users✓
- b.50 users
- c.133 users
- d.200 users
Capacity is one user per 20 square feet for pools other than spas, so 2,000 ÷ 20 = 100. The 133 figure uses 15, 200 uses 10, and 50 uses 40.2025 CBC §3120B.2
What does the capacity sign state for a 150-square-foot public spa pool?
- a.10 users
- b.15 users✓
- c.7 users
- d.30 users
A spa's capacity is one user per 10 square feet, so 150 ÷ 10 = 15. The 7 figure uses 20, 10 uses 15, and 30 uses 5.2025 CBC §3120B.2.1
A public pool must be reached by what kind of gates and doors under the enclosure rules?
- a.Manually closed by staff and opening in
- b.Self-closing, self-latching, outward✓
- c.Spring-loaded and opening either way
- d.Self-latching and opening inward
Gates and doors have self-closing, self-latching devices and open outwardly away from the pool. Inward-opening, either-way and manually closed gates fail.2025 CBC §3119B.2
What height range may the hand-activated hardware on a public pool gate occupy?
- a.24 to 30 inches above the deck
- b.42 to 44 inches above the deck✓
- c.12 to 18 inches above the deck
- d.60 to 72 inches above the deck
Hardware is no lower than 42 inches and no higher than 44 inches above the deck or walkway. The ranges 24 to 30 and 12 to 18 inches are too low, and 60 to 72 inches is too high.2025 CBC §3119B.2
Which of these is required where gas chlorine is used?
- a.A 0.5 ppm chlorine alarm✓
- b.A decorative fountain in the room
- c.A lifeguard chair beside the door
- d.A ceiling fan on a manual switch
The alarm system is audible and visible, with the sensor within 6 inches of the floor, and activates when concentration exceeds 0.5 ppm. A fountain, a lifeguard chair and a manually switched fan do not detect chlorine.2025 CBC §3135B.4
How many accessible means of entry does a 600-linear-foot public swimming pool require?
- a.Three of some kind of entry
- b.One, and it is a pool stair
- c.Two, one a lift or sloped entry✓
- d.One, and it is a transfer wall
Pools with 300 or more linear feet of wall need at least two means, one of them a lift or sloped entry. A stair or transfer wall alone does not meet it.2025 CBC §11B-242.2
What accessible means of entry does a wading pool require?
- a.A pool lift
- b.At least one sloped entry✓
- c.Waived, if the pool is shallow
- d.A transfer wall
Wading pools need at least one accessible means of entry that is a sloped entry. A lift or transfer wall is not what the section lists, and shallow depth does not exempt.2025 CBC §11B-242.3
A cluster of 40 spas needs how many to comply with the accessible entry rule?
- a.2✓
- b.40
- c.8
- d.1
Not more than 5 percent but not fewer than one per cluster, so 5 percent of 40 is 2. The figure 1 is less than 5 percent here, 8 is 20 percent, and 40 is every spa.2025 CBC §11B-242.4
A pool has 200 linear feet of pool wall. What accessible entry provision applies?
- a.Two transfer walls are required
- b.One may do if lift or sloped entry✓
- c.An accessible entry is waived
- d.Three accessible entries are required
Pools with less than 300 linear feet need no more than one accessible means of entry, provided it is a lift or sloped entry. More entries, none and two transfer walls are not what the exception says.2025 CBC §11B-242.2

What are the wave action pool and sand-bottom pool allowances?
- a.An accessible entry is waived entirely
- b.Pool stairs are the access permitted
- c.One may do if lift, slope or transfer✓
- d.Three accessible entries are required
Wave action pools, leisure rivers, sand-bottom pools and similar pools where access is limited to one area need only one accessible means of entry of the stated types, so one lift, slope or transfer arrangement may do. The entry is not waived, stairs are not an accessible means, and three entries are more than the rule asks.2025 CBC §11B-242.2
What is the maximum release height of the latch operable part on an accessible pool barrier gate that is self-latching but not key-locked?
- a.24 inches
- b.12 inches
- c.54 inches✓
- d.80 inches
Access gates in pool barriers may have the release of latch at 54 inches maximum above the ground if the self-latching devices are not also self-locking by key, electronic opener or integral combination lock. The figures 24 and 12 inches are lower than the limit, and 80 inches is far higher.2025 CBC §11B-309
At what water depth must a pool lift be located?
- a.Between 60 and 72 inches
- b.Between 36 and 48 inches✓
- c.Between 100 and 120 inches
- d.Between 12 and 24 inches
Pool lifts are located where the water level is 36 to 48 inches. The range 12 to 24 inches is too shallow, and 60 to 72 and 100 to 120 inches are too deep.2025 CBC §11B-1009.2.1
A single-person pool lift is rated for 250 pounds. How is it judged?
- a.Over the 100-pound maximum capacity
- b.Within the code, which sets 150 pounds
- c.Within the code, which sets 200 pounds
- d.Under the 300-pound minimum capacity✓
A single-person lift has a capacity of at least 300 pounds, so a 250-pound rating falls short. The 200- and 150-pound figures are not the code, and no 100-pound maximum exists.2025 CBC §11B-1009.2.9
A pool lift's seat reaches only 10 inches below the stationary water level. What is wrong?
- a.It must submerge at least 6 inches
- b.It must submerge at least 18 inches✓
- c.It must submerge at least 48 inches
- d.It must submerge at least 36 inches
The seat submerges to a depth of at least 18 inches, so 10 inches is too shallow. The 36- and 48-inch figures exceed the requirement, and 6 inches is below it.2025 CBC §11B-1009.2.8
A sloped pool entry must extend to what depth below the stationary water level?
- a.6 to 12 inches
- b.48 to 60 inches
- c.24 to 30 inches✓
- d.72 inches
Sloped entries extend to a depth of 24 inches minimum and 30 inches maximum, and a landing is placed within that range. Depths of 6 to 12 inches are too shallow, and 48 to 60 inches and 72 inches are too deep.2025 CBC §11B-1009.3.2
What is the maximum running slope of an accessible ramp run?
- a.1:2
- b.1:8
- c.1:12✓
- d.1:20
Ramp runs have a running slope not steeper than 1:12. A 1:8 or 1:2 slope is steeper, and 1:20 is gentler than the maximum rather than the limit.2025 CBC §11B-405.2
A designer draws a transfer wall 22 inches above the deck. How does Chapter 11B treat that height?
- a.Too high, since 16 to 19 inches is the range✓
- b.Too low, since 30 inches is the minimum
- c.Within range, since the height is unspecified
- d.Within range, since 20 to 24 inches is the range
The transfer wall height is 16 to 19 inches from the deck, so 22 inches is too high. The 20-to-24-inch range, the 30-inch minimum and an unspecified height are not what the section says.2025 CBC §11B-1009.4.2
