1. Decision at the decision-making level: The system may be cancelled because the decision-making level thinks that the system is invalid or there are other better alternatives, so it decides to stop using the system.

2. Shortage of funds: The cancellation of the system may be due to the shortage of funds, and it is impossible to continue to maintain and support the operation and update of the system. In the period of economic contraction, enterprises may cut unnecessary expenses, including the maintenance costs of some management systems.

3. Technical problems: There may be technical problems in the system, which cannot meet the actual needs or have serious security loopholes, so it is cancelled to avoid potential risks and problems.

In this case, the following solutions can be considered:

1. Re-evaluation requirements: Re-evaluate the safety management requirements of the enterprise to ensure that the safety management responsibilities can still be effectively performed after the system is cancelled. We can consider introducing other safety management tools or readjusting existing management processes.

2. Looking for alternatives: Study other safety management systems or tools in the market to find alternatives suitable for the needs of enterprises. Ensure that the new system is stable, safe and easy to use, and carry out appropriate training and promotion.

3. Strengthen personnel training: No matter whether the self-service management system is adopted or not, it is necessary to strengthen the safety awareness and training of employees to ensure that everyone can fulfill their own safety responsibilities, thus ensuring the safe production of enterprises.

The best scheme should be determined according to the specific situation, and the influence of system cancellation on safety management should be considered, and corresponding remedial measures should be taken to ensure the smooth progress of safety production.
