Emergency Escape Chute

Invented in late 1950's with elastic outer cloth to allow evacuee to control descending speed. However, this design was caused the problem of collison between evacuees. Therefore, another design of internal spiral slide was created in early 70's to overcome this problem. Since then, there were three different designs created; vertical spiral descent with single exit at bottom of chute; vertical spiral descent with multiple zippered exits along the chute body in 2 meters internal for variable height operations; incline slide descent which required anchorage, ideal for hospital patient on stretcher.

The chute also comes in three different outer cloth material for various application needs; flame retardant treated industrial grade heavy duty polyester for standard application; flame retardant treated polyester mesh for highwind location and Dupont Kelvar for extreme fire protection.
