When employee of the restaurant attended a fire-safety seminar, they watched a fire official demonstrate the proper way to operate an extinguisher. “pull the pin like a hand grenade,” he explained, “then depress the trigger to release the foam.”
Later, an employee was selected to extinguish a controlled fire in the parking lot. In her nervousness, she forgot to pull the pin. The instructor hinted, “like a hand grenade, remember?”
In a burst of confidence, she pulled the pin—and hurled the extinguisher at the blaze.
