	Providing and assuring safe conditions for personnel is a key parameter required to operate the European Spallation Source (ESS). The main purpose of the Personnel Safety Systems (PSS) at ESS is to protect workers from the facility's ionising prompt radiation hazards, but also identify as well as mitigate against other hazards such as high voltage or oxygen depletion. PSS consist of three systems: the Safety interlock system, the Access control system and the Oxygen deficiency hazard (ODH) detection system. The Safety interlock system ensures the safety functions of the PSS by controlling all hazardous equipment for starting the beam operation and powering the RF-powered units and allowing its operation when personnel is safe. This paper will describe the ESS PSS Accelerator Safety interlock system's scope, strategy, methodology and current status.
