Occupant vulnerabilities determination

Determination of Occupant Vulnerabilities as a Function of Building Damage... 

Occupant vulnerabilities are one of the key factors in determining the levels of both individual and aggregate risks for building occupants. Occupant vulnerabilities are used in risk screening as discussed in Chapter 4 and are used in detailed risk assessments.

All recruitment and selection activities should begin with a job analysis. Job analysis allows the task requirements of a job to be precisely determined. Furthermore, job analysis allows the safety risks associated with a job to be determined, and also the identification of the knowledge, skills, and abilities required to work, both safely, and at a satisfactory performance level. It is well established that the occupation or job a person is performing substantially influences accident vulnerability (Ford and Wiggins 2012). In other words, it is vital for safety, for the specific hazards and risks associated with a job to be identified, and conducting a job analysis is an approach which can be used to collect this information. Without the essential information which job analysis provides, it is impossible to provide job applicants with a realistic safety preview for the job (see Chap. 3, Sect. 3.7.2.1), and difiicult to know what competencies a new employee needs to bring to the job, and therefore what should be measured in a selection program. 

The critical nature of occupational safety management tools such as risk assessments and criticality and vulnerability studies reflects just a glimpse of the methodical tools of the occupational safety manager. The risk assessment itself looks at the value of organizational assets, accounting for both the criticality and vulnerability of the asset to determine the amount of the occupational safety investment. In itself the comprehensive process of risk analysis utilizes a process of critical thinking. 

A preliminary system safety assessment (PSSA) is essential in order to determine (and agree) the depth of assessment needed, the criteria utilised and the manner in which the safety objectives are to be accomplished. The PSSA concentrates on the functions and vulnerabiUties of the system instead of the detailed analysis, and can thus be conducted prior to the definition of the system s architecture. The PSSA remains a live document until the final SSA can be issued. By the preliminary design review (PDR), the PSSA should include functional failure consequences to the aircraft and its occupants consequences of other possible malfunctions of a system (e.g. overheating) and their effects on surrounding systems consequences to the system of failure in other systems or parts of the aircraft, identification of any possible common-mode failures or cascade failures which my need detailed investigation the identification of possible vulnerabilities to flight crew or maintenance error.
