In order to optimize the personnel training program of fire protection engineering, improve the personnel training system of fire protection engineering, fully implement the leading role of "craftsmanship" in the personnel training of colleges and universities, and improve the job competence of fire protection engineering professionals, the article conducted a questionnaire survey on past graduates of fire protection engineering, personnel engaged in fire protection engineering‐related work and students studying in fire protection engineering. The article conducted a questionnaire survey on past graduates of fire protection engineering, personnel engaged in fire protection engineering and students studying in fire protection engineering. The article conducted a preliminary study on the construction of fire engineering job competency model under the spirit of craftsmanship through questionnaire survey method and statistical analysis method, and adopted the principal component analysis method to screen the indicators, and carried out maximum variance orthogonal rotation on the screened principal components to extract the characteristic elements of fire engineering job competency, and finally obtained two principal components of fire engineering job competency, namely basic knowledge ability and professional knowledge ability, for the future This will provide reference and borrowing for the construction of fire engineering job competency model and the optimization of fire engineering personnel training program.
