Barrier analysis human factors

Many hazard analysis and risk assessment techniques have been developed. These are just a few of the methodologies mentioned in the literature preliminary hazard analysis gross hazard analysis hazard criticality ranking catastrophe analysis change analysis energy flow/barrier analysis energy transfer analysis event tree analysis human factors review the hazard totem pole and double failure analysis. There are many other hazard analysis systems. 

Analyze Barriers and Potential Human Performance Difficulties During this phase of the analysis process, the barriers that have been breached by the accident are identified. TTiese barriers could include existing safety systems, guards, containment, etc. This analysis is called barrier analysis. The causal factors from SORTM are also applied in more detail. 

Accelerated development schemes have made scientists more dependent on analytical information, and consequently, they are more apt to want to control or perform analysis activities themselves. No doubt the human factor will inevitably arise and create reluctance, and perhaps, barriers to adopt new approaches. For example, the LC/MS applications that deal with open-access support for combinatorial and medicinal chemistry made aspects of acceptance quite clear. A chemist preferred simple answers to simple questions. 

The critical PSFs for the action were identified during the detailed barrier analysis from the human factors experts. They are presented in Table 1 and they refer to the field operators and field supervisor. Different human factor aspects were considered referring both to the operators characteristics (experience), the working...
