What is the final reporting time for Class A/B mishaps?

• A. 24 hours
• B. 72 hours
• C. 48 hours
• D. 30 hours

Answer: (C)

Final reporting time for a serious mishap is 48 hours. This deadline ensures that the most critical incidents are documented quickly enough to support timely safety actions and data collection. After a mishap meets Class A or B criteria, investigators gather injuries, damage, witness statements, and the sequence of events, then file a complete report to the designated safety authority within 48 hours. This timeframe balances the need for prompt, accurate information with enough time to assemble the necessary facts. Immediate notification is a separate requirement, occurring right away, while the final report follows within the 48-hour window.
