    Fires can cover a home in 60seconds! Are you prepared with a quick and safe method of fire escape? While most of us are within a few steps of a window in most of our homes, the upper floor presents unique challenges. The key to survival is planning ahead for the upper floor escape.

The two- and three-story fire escape ladders are the most common types, and can be purchased locally at hardware stores. While doing an Internet research, I found fire escape ladders for four- and five-and six-story homes. Fortunately, the majority of Livingston County homes can easily get by with the two- and three-story models.

The first task in planning an upper floor escape is taking the time to look out of each window and see where it leads you. Sometimes a straight drop is best for hanging a ladder on. Other windows will drop you to a lower roof, where you can wait for another ladder from outside the home to reach you.

Escape ladders usually come in a box that will easily slide under a bed or in a closet. When needed, you just slide it out, and place it near the window. Open the window as you have determined by now that a door escape from the room is not practical due to heat, smoke and fire conditions,. Make sure the hanger(挂钩) will fit in with the window, for which it is intended. It usually has a J-shaped hook, which hangs over the window edge.

Once you decide a room to store the escape ladder in, make sure the family members know where it is. If the stairs leading down are blocked due to the fire, head into the room with the escape ladder and close the door behind you. Fix it out of the window and begin climbing down. Have a stronger person go down first, who can then assist others.

Do as much planning and preparation well in advance of ever needing to use these fire safety skills and you and your family will remain safe.
