If an unauthorized product release meets the requirements for reporting, verbal notification must be made within how many hours?

1. 12 hours

2. 24 hours

3. 48 hours

4. 72 hours

The correct answer is: 24 hours

When an unauthorized product release occurs, immediate and effective communication is vital for prompt response and remediation. California regulations require that verbal notification of such incidents be made within 24 hours to ensure that appropriate actions can be taken to limit potential environmental impact and ensure public safety. This timeframe allows regulators to mobilize necessary resources and coordinate efforts to address the release. In contrast, longer timeframes—such as 48 or 72 hours—would delay critical emergency responses, potentially resulting in greater harm or contamination. Additionally, a 12-hour notification might be considered too short given the complexities involved in assessing and reporting such incidents comprehensively. Therefore, the 24-hour requirement strikes a balance between timely notification and the need for thorough investigation and communication.
