What primary information must an SSE provide to an inspector when reporting a high potential incident?

The primary information that a Site Senior Executive (SSE) must provide to an inspector when reporting a high potential incident includes the location, date, and number of persons involved. This information is critical because it establishes the context of the incident, which is essential for any investigation. By clearly defining where and when the incident occurred, inspectors can better understand the circumstances surrounding it and assess compliance with safety regulations. Knowing the number of persons involved helps inspectors gauge the scale of the incident and determine if it necessitates further investigation or intervention.

Other options, while they may provide useful information, do not address the immediate and critical details needed for an initial report to the inspector. For instance, details of injured persons and their medical histories may be relevant but are more appropriate for a medical response rather than an initial reporting context. Similarly, complete documentation of safety protocols may be necessary for a broader safety review but is not fundamental to the initial incident report required by inspectors. Names of all staff present can be helpful for follow-up but does not capture the essential situational overview that the specified primary information provides.
