What is the primary objective of the "stop, drop, and roll" technique?

The primary objective of the "stop, drop, and roll" technique is to extinguish flames on a person's clothing. This method is designed specifically for individuals who are on fire. By stopping, a person avoids further movement that could fan the flames. Dropping to the ground minimizes the surface area exposed to flames, while rolling smothers the fire against the ground, cutting off the oxygen supply. This technique is a crucial lifesaving measure during fire incidents and is widely taught in fire safety education.

The other options, though related to fire safety, do not directly address the intent of the "stop, drop, and roll" technique. Escaping from smoke-filled rooms involves different strategies, and signaling for help or preventing the spread of fire pertains to various other safety measures and protocols not encapsulated in this specific technique.
