Safety-First, Inc., makes portable ladders that can be used to exit second-floor levels of homes in the event of fire. Each ladder consists of fire resistant rope and high-strength plastic steps.

Each ladder and cape, when not in use, is rolled up and stored in a pouch the size of a backpack and can easily be taken on trips and vacations.
