How many decibels is a lifeguard whistle?

Very loud! Typically, a lifeguard whistle is 110-115 dB on the low end, and 120 dB on the high end. To put that into perspective, the siren on an ambulance is also 115 dB - if you're standing right next to it. As for 120 dB, it's akin to a clap of thunder!

What are the lifeguard whistle signals?

The length and number of times that a lifeguard blows their whistle communicates vital information to swimmers and other emergency personnel. The most common signals are: 1 short whistle: This is meant to gain the attention of members of the public. Whether to tell a kid to stop running at the pool, or a beach goer not to swim out past a marked point, a single whistle is used to warn against or interrupt dangerous behavior. 2 short whistles: When an event occurs that is serious enough for the lifeguard to leave their chair to intervene or investigate directly, 2 short whistles are blown to alert other lifeguards to the situation. 3 short whistles: This is the signal for an emergency situation, calling all hands to assist. This is the most dire signal, as it often means that someone has been seriously injured, or is in an otherwise life threatening situation.

What are the red things that lifeguards carry?

That red tube on a rope is called a rescue tube. It isn't always red, but it will always sport a high visibility coloration. The tube is made of plastic and is hollow inside, allowing it to serve as a floatation device that a struggling swimmer can cling to. The lifeguard can also use it to assist with buoyancy when they need to swim an incapacitated person to shore.

What does 3 whistles mean in lifeguarding?

As mentioned in the previous answer, when the whistle is blown 3 times it means that a serious emergency is taking place. If someone is drowning, has suffered a grave injury, or has their life in jeopardy in any way, 3 whistles will alert all emergency personnel to take immediate action.
