Tracking Hazards

Hazard Tracking Log. In addition to the above analysis, a hazard tracking log (HTL) should be maintained. This log is to ensure all open loops are closed and ensures the appropriate level of management is identified as being involved in the acceptance of risk. 

If the facility has an overall hazards tracking system then its workings should be included in the audit report. 

Safety is achieved by continuing to use the safety precedence sequence to control hazards until all identified hazards are eliminated or controlled to an acceptable level and residual risks are formally accepted. The detailed procedures for hazard tracking and risk resolution should be included in the SSPP. 

The hazard tracking, review requirements, and risk acceptance process are basically the same as for other MIL-STD-882B programs. 

A systematic method must be established to document and track each identified hazard throughout the life cycle and to ensure that control measures are, in fact, implemented. The method recommended is to use a hazard tracking log as a permanent part of the project documentation. 

A data collection and retrieval system must be developed to support the system safety effort. This system includes project description and historical data as well as hazard tracking information. 

The hazard tracking log provides a means of tracking hazards throughout the life cycle and documenting the status of corrective actions. 

The hazard tracking log is prepared as an add-on to the PHA and prepared as soon as the PHA is completed and delivered. The hazard tracking log is then updated as control actions are taken and verified. Summary reports of hazard tracking status are prepared and available for all formal system safety reviews. 

The hazard tracking log is normally prepared and maintained by the safety staff. 

Because the hazard tracking log is an extension of the preliminary hazard analysis, the PHA must be complete before the hazard tracking log is needed. Information needed to complete the hazard tracking log includes appropriate drawing numbers, change orders, and other documents that verify that hazard controls have been implemented. 

A hazard tracking summary is prepared and available for all formal system safety review meetings. The summary should list all open (uncontrolled) hazards in chronological order and/or by RAC. This type of report should also be available on an as-needed basis. 

Figure 8-3 shows a hazard tracking log incorporated in a preliminary hazard analysis worksheet. 

Reference Document column Lists the drawing and/or other hazard tracking reference that documents the corrective action(s). Verification Signature(s) column Contains the signature of the person(s) responsible for maintaining the hazard tracking log and the date the verification was made. 

Detailed project description and detailed accident information are required to conduct an in-depth accident analysis. Historical data, existing hazard analyses, and the hazard tracking log are also important. 

What columns are added to the PHA to form the hazard tracking log ... 

Based on the PHA, the safety organization prepares a hazard tracking log as outlined in Chapter 8 (or as described in the system safety program plan). 

The PHL, PHA, and hazard tracking log are reviewed by the appropriate review boards relatively early in the design phase (as prescribed in the SSPP). At a minimum, the manager or supervisor of each member of the SSWG (for... 

Formal hazard discovery forms (Fig. 11-1) may be used to ensure that hazards that are identified are documented, evaluated, and entered into a hazard tracking system. 

The PET chart is used primarily as a working tool to guide the analyst through the analysis. Information, especially items identified as less than adequate (red) is transferred to a PET analysis worksheet (see Fig. 16-6). These worksheets are then used like other hazard analysis worksheets for hazard tracking and preparing a narrative summary of the analysis. 

Closed-loop hazard tracking system or plan...

In addition to the hazardous conditions that develop during daily operations and are incorporated in the closed-loop hazard tracking system, the customer may require the contractor to perform a formal periodic risk assessment (usually annually, but it can be more frequent if the customer so desires or if operational activities dictate) of all facilities in which operations will occur. The risk assessment will also take into consideration the hazards associated with the permanent equipment and hardware assigned for use in the facility. The accident risk assessment then becomes a detailed safety analysis of a facility, including its systems and functions. 

FI. Does the hazard-tracking system address hazards found by employees, hazard analysis of routine and nonroutine activities, inspections, and accident or incident investigations ... 

Another way to track hazards is to transfer information from the original hazard reports to a separate hazard tracking report. This system can receive information on all uncorrected hazards and not just information...
