Do you live or work in a four or higher story building, one without a fire escape? When there's a fire or other danger you may try the door but are prevented from escape due to flames or explosive hazzard that will set upon you unless you find an appropriate escape. In instances like this you should certainly call the fire department. This is a plausable and proper way to get help. But as you wait for a response, the damage gets worse leaving you trapped until help arrives. It may be best to plan out your own escape before its too late. In that the longer you wait the less your chances are of getting out alive.

IDEA:

The umbrella parachutte is a carry tote that is designed to glide one to safety from appx. 300 feet in the air. The umbrella parachutte is made of nylon and kevlar and looks like a mini umbrella. This safety device is designed to assist a person who must escape a building or structure at certain levels. To use the umbrella parachutte, you securely wrap the safety strap around your shoulders like a back pack. You then deploy the parachutte portion out of the window and it will begin to serve as your safety net by gliding you to the ground. Once you are attached to the parachutte and exit out into the open air the parachutte will begin its slow decent to the ground.  The umbrella parachutte is light and transportable to carry in any bag or suitcase. It is also durable enough to carry persons of up to 350 pounds to the ground safely. The umbrella parachutte is great for personal safety when help is unable to arrive and yes it is reuseable for up to three times.
