Since the danger is absolute, we require that leaders at all levels to be able to alarm bells ringing, the safety of the work of unremitting efforts to safety work as a daily routine, not to highlight the type of or Campaign-style approach to production safety work;

Some leaders speak of production and economic work is a set of very expert, but speak of safety work is not so expert, and even their own shoulder safety responsibilities are not aware of, let alone how to fulfill these responsibilities;
