An infusion system includes a wearable infusion device, a safety assembly, and a tool. The device includes a liquid medicament dispenser having a base attachable to a patients skin and that, when enabled, causes the liquid medicament to flow to beneath the skin of the patient, and an actuator that, when engaged, enables the dispenser. The safety assembly precludes unintended engagement of the actuator and the tool is arranged to disable the safety assembly.
