Table I: Hazard-analysis worksheet.
For this evaluation, there was only one hazard to consider: the BL2 organism. The HACCP process was significantly streamlined to control for operator safety and the high level of regulatory requirements for pathogenic BL2 organisms. The hazard was always considered to be significant in this case study (see Table I).

Table II: HACCP plan form for the evaluation of the effectiveness and control of standard operating procedures (SOPs). RTD is resistance temperature detector. EH&S is environmental health and safety.
As shown in Table I, each proposed inactivation mechanism or procedure was deemed crucial because they were proposed as backups for the primary autoclave inactivation method (which was itself deemed crucial). The evaluation of the effectiveness of the procedures including how they would be controlled to achieve consistency among critical parameters is shown in Table II.


In this case study, identifying effective backup inactivation methods to compensate for times when the primary inactivation autoclave is unavailable for use reduces the risk of a breach of containment in the facility. Table II demonstrates that the backup procedures identified are effective and can be consistently controlled. Table II also indicates that additional, more detailed procedural controls and more clearly defined functional-area responsibilities are required to maintain proper containment of the BL2 organism. These additional procedural controls are identified in the "recommended actions" column of Table II.


For this case study, the outputs of the risk-assessment process, including recommendations for additional procedural and functional-area controls, were documented in a risk-assessment report. This report became part of the operating history of the manufacturing facility and the associated product. The project team of each functional area affected by the results of the risk assessment reviewed and signed off on the results and recommendations. The project team assumed responsibility for implementing the recommendations that arose from the quality risk-eanagement process.


In the case study presented, it may be appropriate to review the backup procedures as additional detailed procedures are developed. This activity will ensure that the backup procedures are fully effective and controlled in an effort to contain appropriately the BL2 organism.
