Which class of MISHAP is serious enough to warrant formal MISHAP Analysis Board action?

The correct choice relates to Class B mishaps, which are significant enough to require a formal Mishap Analysis Board (MAB) investigation. Class B mishaps typically involve incidents that result in substantial damage to property or have a serious risk of injury or fatality. A pivotal aspect of Class B mishaps is that they can lead to a total cost of damages exceeding a certain monetary threshold. This level of impact means that a comprehensive analysis is necessary to understand the root causes and to implement measures to prevent recurrence.

In the context of mishap classifications, a formal MAB investigation serves to dissect the circumstances surrounding the incident in detail, ensuring thorough documentation, accountability, and the development of actionable safety recommendations. This level of investigation is crucial for fostering a safer operational environment and promoting lessons learned across the organization.

Other mishap classes do exist, but Class A typically involves even more severe incidents, such as fatalities or total loss of property, leading to potentially more extensive investigations. On the other hand, Classes C and D involve less severe incidents that usually do not warrant the same level of formal inquiry, as they either result in minor injury or property damage that falls below the thresholds set for more serious classifications.
