Local safety production supervision and management bureau. Empty work permit belongs to the special industry work permit, which needs to be handled at the research and training center under the former Safety Supervision Bureau of the local safety production supervision administration, because some people engaged in aerial work or climbing work directly go to the emergency management office or the emergency management bureau to ask, but they can't handle it, because this form does not directly accept students' registration, and they need to receive safety education at the research and training center under the unit before they can apply for it.
