The objective of this study is to synthesize and analyze the systems for Certification of Personnel
Competencies for Explosive Atmospheres in U.K., IEC, Japan, and Singapore, and thus propose
feasible programs for Taiwan. The documentary analysis was employed to attain the goals. The main
research steps contained following: ascertaining research objectives, determining the data collection
method, synthesizing and analyzing the systems, holding an experts conference, drafting a feasible
program. The results indicated the systems for Certification of Personnel Competencies for Explosive
Atmospheres in the mentioned-above countries, and the researchers in this study suggest that the
industries could refer to NECA0902 and the government could amend the relevant regulations to
establish the local system.
