Aerialift Safety Device and Fall Restraint

摘要

Systems, methods and apparatus to increase the frequency and/or probability of use of a personal safety device, and to reduce the probability that a person is exposed to a dangerous situation unless and until a safety device has been engaged. One apparatus includes an alarm that is activated by the use of a mechanized instrument to remind a worker using the instrument to engage a safety device before proceeding to use the instrument, and an actuator for a switch that can be used by the worker to deactivate the alarm. Another apparatus includes a switch to prevent operation of a mechanized instrument unless a safety device is engaged by a worker using the device, and an actuator for a switch that can be used by the worker to permit operation of the instrument. In a mechanized instrument, another apparatus includes a plurality of sensors that measure distances between themselves, and a microprocessor to activate an alarm concerning engagement of a safety device before operation of the instrument and/or to prevent use of the instrument until a safety device is engaged.

1. An apparatus for personal protection from dangers potentially associated with using a mechanized instrument in situations in which bodily restraint is needed, comprising: (a) an alarm to warn of a dangerous situation, (b) a switch to deactivate the alarm, (c) an actuator to operate the switch, and (d) an engagement fixture that engages a safety device with a structure at a point of engagement, wherein engagement of the safety device reduces the danger presented by the situation; and wherein the actuator constitutes a first component, and the engagement fixture constitutes a second, separate component.
