Question

Make sure that the device isn't too tight. _______ and _________ must be worn loose enough so that water can flow under the lifejacket to turn the wearer face up.

Answer 1

Lifejackets must not be too tight and should allow water to flow underneath, ensuring they can turn the wearer face-up in the water for safety.

Step-by-step explanation:

When referring to safety devices such as lifejackets, it is vital to ensure that these are not too tight when worn. Lifejackets and other personal flotation devices must be worn loose enough so that water can flow under the lifejacket. This is crucial because the water helps to turn the wearer face up in case of submersion, providing an important safety function to protect against drowning. It's fundamental to practice proper safety measures during water-related activities like scuba diving, where understanding and managing buoyancy and pressure are equally important.
