How soon should an SSE notify an ISHR about a high potential incident or serious accident?

Notifying an ISHR (Incident Safety and Health Report) about a high potential incident or serious accident "as soon as practicable after becoming aware" is essential for ensuring safety and effective risk management. This approach emphasizes the urgency of reporting incidents to allow for immediate investigation and analysis of the circumstances surrounding the incident.

Timely reporting can significantly enhance the ability to implement corrective actions, prevent future occurrences, and demonstrate compliance with safety regulations and standards. It recognizes that delays may impede the understanding of the incident's context and the potential risks, which could lead to additional incidents if not addressed promptly.

This option reflects best practices in workplace health and safety protocols, where immediate awareness and action can help mitigate risks and protect employees and stakeholders. The emphasis on 'practicable' also implies a reasonable standard, allowing for genuine circumstances that may affect immediate reporting, ensuring a balance between immediacy and feasibility.

In contrast, the other options suggest timeframes that could delay the investigation and response, potentially compromising safety and failing to adhere to regulatory guidance that prioritizes prompt communication about safety issues.
