The diver down flag is a warning signal to other boats that there are divers in the water. It is usually yellow and black, but it can be other colors as well depending on the background color of the boat. When you see this flag-waving, it means that someone from your vessel has gone into the water for a dive or exploration. There are two types of flags: “diver off” which means all divers have returned safely to their vessel, and “diver down,” which indicates a situation where someone has gone overboard or fallen out of an open hatchway.
A diver who falls overboard should not attempt to swim back to their boat immediately because they will tire easily and risk drowning before reaching safety. Instead, wave your arms to get attention and deploy the “diver down” flag to alert other boats that you require assistance.
Do not take it personally if someone takes a long time to come for you, because they might be busy with another emergency situation or simply didn’t see your signal.
A diver who has surfaced should return all gear (including weapons), shut off their regulator, turn on their strobe light, inflate their buoyancy compensator device balloons until they are at neutral buoyancy underwater again, identify themselves by yelling out “OK!” three times in rapid succession while arching up into an upright position from waist-deep water before climbing onto their vessel’s deck so as not to slide back under the surface of the water when rounding corners.
Diver Down Flag Colors
The International Maritime Organization, which governs the rules of international sea travel, specifies that a diver down flag should have two colors: red and yellow. The most common specification for these is to use an orange flag with either a square (red on top) or circular (yellow on bottom) white panel in the center. Sometimes there are also horizontal stripes of alternating colors around the border of this central area too. The height-to-width ratio can be as little as one to three; if it was taller than wide then you would need more panels — but otherwise, it doesn’t matter how many panels are across its width because each has equal value no matter where they’re positioned vertically along its length. This means it should be a square or circle with an orange background and white stripes.
The first type of diver down flag is the international signal consisting of two colors, red on top yellow underneath (though sometimes it’s just one color), which means “diver down.” The second type goes back to when diving was done without breathing apparatus: It shows three horizontal stripes in blue, black-and-white, and black warning that there are dangers underwater like mines. There isn’t much need for this though because now people use decompression chambers instead.
There is no specific length requirement for these flags; they can range from 12 inches all the way up to six feet tall depending on their intended purpose. Divers who work underwater usually use a diver down the flag that is at least six feet tall and 12 inches wide, because the larger size makes it easier to notice.
Why are there two types of diver down flags?
The first type consists of two colors: red on top yellow underneath (though sometimes it’s just one color), which means “diver down.” It shows three horizontal stripes in blue, black-and-white, and black warning that there are dangers underwater like mines. There isn’t much need for this though because now people use decompression chambers instead.
The second type goes back to when diving was done without breathing apparatus: It has an orange background with white stripes meaning “divers please stop”. These flags typically only measure about three feet on each side, but they’re still pretty hard to miss.
The diver down flag is a signal for boats and other watercraft that there’s a possible danger in the area below them; it can also be used by people swimming underwater as well. It has two different meanings depending on its color: red-and-white means “diver down” while orange means “divers please stop”. The size of the flag varies from six feet tall to twelve inches wide so it appears more easily on such large bodies of water!
What does the diver down flag look like? It depends which type you mean – there are two types: one with three horizontal stripes in blue, black-and-white, and black warning flags, and one with an orange rectangle in the center. The flag typically measures about three feet on each side but it’s still pretty hard to miss!
