Safety systems requiring intentional function activation and material testing systems including safety systems requiring intentional function activation are disclosed. An example material testing system includes: an actuator configured to control an operator-accessible component of the material testing system; an operator interface comprising a plurality of inputs; and one or more processors configured to: control the actuator based on at least one of a material testing process or an input from the operator interface; and require two or more inputs to be received within a predetermined threshold time to permit at least one operation of the actuator.

Safety systems requiring intentional function activation and material testing systems including safety systems requiring intentional function activation are disclosed. An example material testing system includes: an actuator configured to control an operator-accessible component of the material testing system; an operator interface comprising a plurality of inputs; a pressure sensitive surface configured to: detect the presence of a pressure on the surface; and output a pressure signal in response to detecting the pressure; and one or more processors configured to: control the actuator based on at least one of a material testing process or an input from the operator interface; and require two or more inputs to be received to permit at least one operation of the actuator, at least one of the two or more inputs comprising the non-detection signal.

A log splitter having an activation lever and a safety lever that defines a pawl configured to engage with a detent associated with the activation lever in an unactivated position so that the activation lever cannot be rotated unless the safety lever is first rotated out of a safety position to remove the pawl from the detent.
