Purpose is to emphasis on accountability, this is what we often say "accidents" four pass "principles".

1, the cause of the accident did not find out don't pass;

2, responsible under processing don't pass;

3, malpractice and the masses, not under education don't pass;

The principle of "four pass" the third meaning is required for the cause of the accident, the must be serious production safety accident investigation and handling of at the same time, also must be put forward to prevent the same or similar accidents feasible prevention measures, implement and supervise and urge the accident unit. Only in this way, is to achieve the ultimate purpose of the investigation and handling of the accident.

The principle of "four pass" the fourth layer of meaning is also the embodiment of safety accident responsibility person, responsible for the accident must be strictly in accordance with the relevant safety accident responsibility regulations and the provisions of laws and regulations for serious processing.

"Four pass", not only stay in oral, but truly, truly, there should be a specific action, not only to find out the reason and deal with those responsible, to carry out the corrective actions, more profound lessons, it is important to extrapolate, to do a good job of production safety supervision and prevention. Production safety accident in the event, often accompanied by the death of innocent lives, this lesson once is enough, don't always learn, even never learn.

Safety in production, responsibility is more important than mount tai, the responsibility in the shoulder, in the person's heart, as long as everyone safe production this alert, always think safety, everywhere holding safety, according to the national production safety laws, regulations, rules, regulations and standards, specifications we each management work, the staff, various departments at all levels of safety responsibility, safety management system implementation in place, implement measures, there is a problem immediate improvement, there are hidden dangers in a timely manner to eliminate, to prevent the occurrence of safety accidents, to ensure the safety in production of the enterprise, to provide security for the construction of a harmonious society.
