Abstract: An illustrative embodiment of a safety block may include an actuator bracket pivotally engaged with a pivot arm. The actuator bracket may be configured to engage a master actuator having a first end moveable with respect to a second end. A secondary actuator may have a first end engaged with the actuator bracket and a second end engaged with the pivot arm such the secondary actuator may cause the pivot arm to move between a first position, in which first position the pivot arm prevents the master actuator from retracting, and a second position, in which second position the pivot arm allows the master actuator to retract.
