The trailer provides a real life simulation of a smoky environment and is aimed at teaching the children proper procedures for exiting in a real life fire situation. This simulation is part of Fire Prevention Week. This year's theme is Prevent Home Fires and is aimed at teaching everyone to protect themselves and their homes by following the simple safety procedures explained throughout Fire Prevention Week. — Released (Text by U.S. Navy)
context_page_description: Crawling or quadrupedal movement is a method of human locomotion that makes use of all four limbs. It is one of the earliest gaits learned by human infants, and has similar features to four-limbed movement in other primates and in non-primate quadrupeds.
context_section_description: Crawling is used mainly:
  When a person cannot yet walk because of being an infant
  When a person cannot walk due to disability, being wounded, sick, or drunk
  In very low places (caves, under a table, in a mine, etc.). Sometimes underground miners need to crawl long distances during their work
  When searching for something on the ground
  To get down to the ground in gardening, for maintenance or other work-related purposes which require a good reach on the ground
  For stealth (camouflage and quietness)
  To lower the field of vision
  As an exercise
  As a token of submission
  For fun or comical purposes
  During a fire, crawling may be used because the air near the ground is easier to breathe
