How does the CSB evaluate responses from recommendations recipients?

Each recommendation is monitored by CSB staff from the time it is issued to closing. CSB staff evaluate recipient responses, and the Board votes to assign status designations to recommendations based on staff evaluation. Recommendations are considered "open" while in progress and "closed" when evidence of appropriate action has been provided. The CSB website is continually updated with each recommendation's status.

What do the status designations for each recommendation mean?

The CSB assigns a status to each recommendation after reviewing the recipient's actions or proposed actions. Below is a brief explanation of the categories with abbreviations in parentheses.

Open - Awaiting Response or Evaluation/Approval of Response (O - ARE/AR) - The recipient has not submitted a substantive response, or the evaluation by CSB staff of a response is pending, or the Board has not yet acted on staff recommendation of status.

Open - Acceptable Response or Alternate Response (O - ARAR) - Response by recipient indicates a planned action that would satisfy the objective of the recommendation when implemented, including a written timetable for completion.

Open - Unacceptable Response/No Response Received (O - UR) - A response to the recommendation has not been received within 270 days of issuance or the recipient responds by expressing disagreement with the need outlined in the recommendation. The Board believes, however, that further dialogue or advocacy may persuade the recipient to act.

Closed - Acceptable Action (C - AA) - The recipient has successfully completed action on the recommendation. The action taken was as specified by the Board in the original recommendation.

Closed - Acceptable Alternative Action (C-AAA) - The recipient has successfully completed action on the recommendation. The action taken was approved by the Board as an acceptable alternative to the original recommendation language that meets the objectives envisioned by the Board.

Closed - Exceeds Recommended Action (C - ERA) - Action on the recommendation meets and surpasses the objectives envisioned by the Board, in a manner that enhances the extent of reduction of future risk.

Closed - Unacceptable Action/No Response Received (C - UA/NRR) - A response to the recommendation has not been received within 270 days of issuance or the recipient response by expressing disagreement with the recommendation or offers an alternative response that the Board does not view as an acceptable alternative. In addition, the Board concludes that further dialogue or advocacy will not persuade the recipient to act.

Closed - No Longer Applicable (C - NLA) - Due to subsequent events, the recommended action no longer applies (e.g., the facility was destroyed and not rebuilt, or the company went out of business).

Closed - Reconsidered/Superseded (C - R/S) - Recipient rejects the recommendation based on a rationale with which the Board concurs. Reasons for this status may include, for example, situations when later facts indicate that the conclusions of the Board should be modified, that concerns expressed in the recommendation were addressed prior to the incident, when a recommendation should have been directed to a different recipient, or when a recommendation is superseded by a new, more appropriate recommendation.
