# Safety device for detecting improper positioning of a ladder

## Abstract

A safety device for detecting improper positioning of a ladder including an alarm connected to an energy source. A longitudinal and lateral level indicator switch are connected between the alarm and energy source with a first orientation for precluding power transfer to the alarm when the ladder is orientated in a safe disposition. The switches further have a second orientation for allowing power transfer to the alarm when the ladder is oriented in a dangerous disposition. Finally, an actuator switch is included for activating the device solely during use.
