·Declaration of conformity report

Step 1: Machine Definition：

·Is to determine the scope of the system to be analyzed, such as the stages of the life cycle of the machine, the parts and/or functions of the machine.

Step 2: Hazard Identification：

·The goal of hazard identification is to form a list of hazards, hazardous states and/or hazardous events, which can describe when and how the hazardous states may cause injuries.

· Hazard identification is the most important step in any risk assessment. Only after the hazards are identified can actions be taken to reduce the risks associated with them. Unrecognized hazards may lead to injuries.

Step 3: Risk estimation
·After confirming the dangerous state and phenomenon of machinery, determine the risk elements, and predict the danger through "the possibility of hazard occurrence" and "its probability"。

Step 4: Risk assessment
·After estimating the risk, evaluate the risk and determine whether it is necessary to reduce the risk.

Step 5: Risk reduction
·When it is necessary to reduce risks, take safety measures such as design changes and safety protection measures shown in step 5.
·Repeat the process from step 1 to step 5, and finally reduce the risk to an appropriate level.
