The CSB issues safety recommendations to prevent the recurrence or reduce the likelihood or consequences of similar incidents or hazards in the future. Recommendations are issued to a variety of parties, including government entities, safety organizations, trade unions, trade associations, corporations, emergency response organizations, educational institutions, and public interest groups. Recommendations are published in CSB reports and are closed only by vote of the Board. The CSB tracks all recommendations and communicates regularly with recommendations recipients to ensure that the recommended corrective actions are implemented.

2018-03-I-TX-8

Strengthen the EVAL Plant’s operator training program by 1) including the known activities, such as bringing ethylene back into the unit, upset conditions like the reactor’s High-High-Pressure alarm, and providing guidance or otherwise clarifying when nonessential personnel should be excluded from being in the unit; 2) including alarm setpoints and actions that operators should take in response to specific process alarms, such as high pressure inside an EVAL Reactor; 3) including directions on when operators should use the emergency open valve; and 4) including safe operating limits, the consequence of deviating beyond the safe operating limits, and the predetermined steps operators need to take to return the process to a safe condition.


Status: Closed - Acceptable Action
Closed - Acceptable Action (C - AA) - The recipient has completed action on the recommendation. The action taken meets the objectives envisioned by the Board.

2018-03-I-TX-10

Improve the EVAL Plant’s safety management system by 1) controlling when chilled liquid is circulated through the heat exchanger during startup; 2) enhancing recognition of liquid ethylene accumulation and response to low-temperature conditions inside an EVAL Reactor through alarms, written procedures, and operator training; 3) implementing a system to manage abnormal operating conditions effectively by, at a minimum, including appropriate technical representation, performing a hazard analysis of temporary or troubleshooting operations, and providing management oversight of any abnormal condition; 4) updating the written startup procedures to include guidance on the appropriate operator actions to take in response to process alarms; 5) using control system guidance to aid operator response to abnormal or upset conditions to keep the process within the safe operating limits; and 6) removing the physical and procedural controls used at the EVAL Plant to restrict board operators from accessing or using the emergency open valve, and updating the written procedures and operator training to provide guidance on when to open the emergency open valve.
