Strengths

There is a proposed analysis concept in Bulgaria which understands the human resource incident occurrence that is a combination of Fault Tree Analysis (FTA) and Task Analysis (TA). There is a Former method which identifies the root cause of an incident.  (SACP, 2015). There are various strengths of the both the analyses which includes safety of an incident or accident. The accident is occurring in the industrial revolution. It helps to identify the main causes and factors of the accident which makes determination to contribute to the people. The incident includes injury of human operators. Employees of the plant industry are given services by the office of “Labor Medicine”. Fault Tree Analysis includes some education systems and trainings provided for healthy and safety condition to employees at the time of incident. These analyses have the strength to identify where and what types of accidents may occur. It has the capability to analyze that how accidents are occurring as well as identify both direct and underlying causes of accidents in Bulgaria (Blacket, 2005).

Weaknesses

There is a common reason for accident which shows the weakness of FTA and TA such as failure of people, equipment, supplies and surrounding. Though Task Analysis has some positive effect of accidents, it has some weaknesses in Bulgaria. It has the negativity of some high risk of chemical company which is showing the bad impact of accidents. There are some combined negativities which influences various working environmental parameters such as noise, harmful substances, dust and carcinogenic chemical. Control of compliance with health and safety at regulation of work is not properly and strictly maintained by the top management (Cilingir, 1998).

There is also some deficit of control and the development demand of the organization includes health secure and accident free condition of working. Metallurgical industry data of safety & health and regulation of labor by the EA indicates that 40% of such conditions are lapse due to bad maintenance of these analyses, 36% are happened because of lapse in the safety provision of work, 21% are because of provision problem of hygiene condition of labor and 3% of them due to legislative issues in such analyses. (Mackhieh, 1998).

Application

            There are various applications of these above weakness of analyses which show the development of both FTA and TA in Bulgaria. The primary application of the incidents examination approach was successfully demonstrated which makes a combination of Fault Tree Analysis and Task Analysis. These factors influence the performance of the operator. From the article it has found that task analysis gives permission to find out which activities are misplaced by the employee of the organization at the time of task implementation. It also gives permission to see the process of work implementation of human being (Bellamy, Geyer & Wilkinson, 2008). The classification of psychological error of human being might be systematically observed by the use of HEIST. The application of HEIST is available in the cases all times when there is an action of erroneous human which is involved in the occurrence of incidents and accidents (Gordon, 2008).
