You don't need to take any certificates after you start working.
After about 3-5 years,
1, you can try to take the examination of registered safety engineer (this is easy to learn), system internal auditor (this needs a little training), environmental protection qualification (there are several kinds of sewage and waste gas in Shandong that need training), special equipment management (this needs training and study hard), and building firefighters (this needs to study hard); These efforts can basically be achieved.
2. You can also try to be a safety assessor (this has little to do with the industry, and the training fee is very expensive, which can be 1 10,000/year), a registered environmental assessment engineer (this is very difficult, starting from 30,000/year), and a registered environmental engineer (it is very difficult to take the environmental major).
3. You can also take the exam as a registered fire engineer (20 13, unknown).
