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.
