A Preventive Safeguard is the initiating event to stop the event from developing further into an incident by which the hazards evaluation of an incident sequence, a preventive barrier is in between the initiating event and a loss event. Effective controls of workplace hazards; help avoid injuries, illnesses, and incidents; minimise or eliminate safety and health risks; and help employers provide workers with safe and healthful working conditions.
Reference Definition by Aiche.org/ccps: A Preventive Safeguard is a safeguard that forestalls the occurrence of a particular loss event, given that an initiating cause has occurred; i.e., a safeguard that intervenes between an initiating cause and a loss event in an incident sequence. (Note that containment and control measures are also preventive in the sense of preventing initiating causes from occurring; however, the term preventive safeguard in the context of hazard evaluation procedures is used with the specific meaning given here.)
