Which of the following items is essential in a quick release situation?

In a quick release situation, having both a survival vest and a knife is essential for safety and survival in the water.

A survival vest is crucial because it is designed to keep the wearer afloat and provides essential tools and equipment that may be necessary in an emergency. It typically includes flotation devices, signaling devices, and sometimes emergency supplies such as a whistle or a flashlight, all of which aid in survival and rescue efforts.

A knife is equally important in such scenarios. It can be used to cut away any entanglements or equipment that may hinder a person's escape from a dangerous situation, such as lines or straps. Additionally, a knife can serve other survival purposes, such as preparing food or signaling.

Together, these items form a critical part of emergency preparedness. Their inclusion in a quick release situation ensures that individuals have the means to free themselves from potentially hazardous conditions while also enhancing their chances of survival and rescue. Having either item alone may not provide the same level of preparedness and response capability.
