You have to ask which safety assessment agencies in specific places have Grade A qualifications, and all localities have Grade A qualifications.
There are only two in Shaanxi Province, one is the Anke Center in Shaanxi Province, and now it is not allowed to take over the separation of government and enterprise; One is 52 1 Weapon Health Research Institute.
There are four Grade A qualifications in Gansu Province: Gansu Lian Management Consulting Co., Ltd., Gansu Xin 'an Safety Technology Consulting Co., Ltd., Gansu Institute of Engineering Geology and Lanzhou Zhongxin Engineering Safety Consulting Co., Ltd. Although each institution has Grade A qualifications, the evaluation directions are different, some focus on the petroleum system and some are non-coal mines.
