• Determine various possible failure modes of equipment, such as mechanical failure, electrical failure, software failure, etc.

• Analyze the cause, frequency and influence degree of the fault.

Environmental factor assessment

• Consider the influence of environmental conditions such as temperature, humidity, dust and vibration on the equipment.

• Assess the possible risks caused by external factors such as natural disasters and man-made destruction.

Operational risk analysis

•Analyze the skill level, operation specifications and training of operators.

•Evaluate the equipment risks that may be caused by misoperation and illegal operation.

• According to historical data, failure mode analysis and expert experience, the probability of various risks is determined.

• Qualitative or quantitative methods can be used for evaluation.

Risk impact assessment

• Evaluate the impact of risks on equipment performance, production efficiency and safety.

• Qualitative or quantitative methods can be used, such as severity grading and loss assessment.

Risk priority determination

• According to the risk probability and influence degree, the priority of risk is determined.

• Give priority to high-risk problems to reduce the overall risk level of equipment.

•In view of high-risk problems, formulate corresponding risk reduction measures.

• For example, equipment maintenance, technical transformation, personnel training, emergency plans, etc.

Risk monitoring and early warning

• Establish a risk monitoring mechanism to detect changes in equipment risks in time.

• Set early warning indicators, and give an alarm when the risk reaches a certain level, so as to take corresponding measures.

Continuous improvement

• Evaluate and improve the equipment risk assessment system regularly.

• Summarize experiences and lessons, and constantly improve risk assessment methods and control measures.
