Markings and Warning Signs

The respective depths of the pools should be marked in a manner meeting the minimum requirements of size, shape, color contrast and interval spacing as set forth by the jurisdictional regulations. If there are no regulatory stipulations, it is recommended that 6” high letters and/or numerals may be considered in a slip-resistant finish located at the deep end, the shallow end, any breaks in slope and spaced no more than 25’-0” apart around the pool perimeter.

  • As part of CH’s role on various committees, we have been tasked with developing guidelines for warning signs around swimming pools. The following protocol was established:
    • Objective #1 – Alert the population that there is a hazard.
    • Objective #2 – Describe the hazard.
    • Objective #3 – State the command.
    • Example – WARNING / SHALLOW WATER / NO DIVING
    • This wording, plus the “No Diving” symbol provides the greatest protection for the owner. This gives the owner the best defense against the legal test – “Did the owner give prompt and sufficient notice of a hazard?”
  • The following considerations should drive what markings and warning signs are used:
    • Health department regulations.
    • Varying liability laws in different states.
    • The vulnerability of the engineer of record if prompt and sufficient notice was not provided.

Deck markers should be located every two-foot interval in the pool slope and not more than 25 feet apart.

Depth markings at lap/competition pool end wall shall indicate the depth at the pool wall.

Warning signs stating “SHALLOW WATER – DO NOT DIVE” or the no diving marker (verify with code requirements) should be provided at the pool perimeter in the deck at pool depths 6 ft. or less. These signs should be located approximately every 25 ft. as required by the local agency.

The typical depth marker location is at the edge of the pool or 3” from the wall.

Four-inch high, vertical pool wall depth markings at the pool perimeter are typically the minimum required by health department regulations. This should be verified with the local agency. Five-inch high, vertical pool wall depth markings should be considered the minimum if the design calls for 1” x 1” ceramic tile.

CH’s standard cantilever gutter is a 6” overhang with a 6” opening to the gutter; an option for the PM is to have a 7” overhang with a 5” opening. This option is typically used on the concrete deck pools.  The face tile will have 1” of concrete above and below the vertical tile markings on the face of the cantilever; this greatly reduces the need for custom tile or hand cut tile.

Vertical warning signs on the pool walls at the water line are often justified because of the rationale that a bather on one side of the pool will be able to read the depth signs across the pool and it’s assumed that the pool bottom profile will be symmetrical.

A movable floor requires deck signage warning the user that the pool depth varies because of a movable floor. An annunciating sign is often available from the manufacturer indicating what the actual water depth is at any particular time.

Application of depth markings and warning signs should be done after final coat of finish paint has cured for at least 24 hours.

Vertical depth markers should be located not to interfere with wall target tile on rollout, fully recessed, or parapet gutter pools.

All YMCA pools should be designed with NCAA markings.

In New York State, “INCHES” and “FEET” must be spelled out for depth markings.

In New York City, add No Diving warning signs around pool deck where water depth is 8’ or less to meet health code requirement.

In New York City, add the word “DEEP” or “DEPTH” after water depth marker.

Michigan Code states that there must be deck markings at underwater benches. At Lakeview HS, “Warning – Bench Below” was acceptable.

Texas Code requires that all depth marker signage be at least 4” high, including the “FT” and “IN”.

When horizontal depth markings are installed directly in the concrete pool deck rather than in the pool beam (deck level gutter) or within a continuous tile band, it is a common installation issue that concrete control joints intersect or conflict with depth marking and warning sign tile locations. This should be avoided whenever possible as the marking tiles will always crack at the control joint intersection.  Depth marker locations should be coordinated during design with the architect/landscape architect plan showing deck joint locations, so that joints do not intersect tile locations.  A general note has been added to the C-H depth marker master details to indicate this as well.  When a control joint intersecting a marker location is unavoidable, the control joint should be aligned with a grout joint within the tile marking.
