In what document should criteria for the response of a predesignated ISO be included?

The appropriate document for including criteria for the response of a predesignated Incident Safety Officer (ISO) is the Standard Operating Procedures (SOP). SOPs provide detailed guidelines and protocols that outline specific roles, responsibilities, and procedures to be followed during incidents.

In the context of emergency management and incident response, SOPs serve as essential resources that establish consistency and clarity in operations. They typically incorporate the necessary steps for various roles, including that of a predesignated ISO, ensuring that all actions are aligned with safety standards and operational directives. This level of detailed guidance is crucial for effective incident management, particularly for maintaining safety during complex operations.

While other documents like Emergency Operations Plans or Risk Management Plans contain valuable information related to overall emergency response strategies, they do not focus as specifically on the day-to-day operational procedures and expectations for the ISO role like SOPs do. Therefore, for precise criteria regarding the function and responsibilities of an ISO, SOPs are the most suitable source.
