4 Hazard list
4.1 General
The following hazardous items are the results of risk assessment of centrifuges within the application scope of this standard according to the provisions of GB/T 15706, and are only some or major ones, not all hazardous items. These hazardous items may occur in the use, transportation, installation, commissioning, maintenance, disassembly and disposal of the equipment under the predetermined conditions specified in the instructions for use.
4.2 Mechanical hazard
4.2.1 Design factors
4.2.1.1 The structural design is wrong or unreasonable, such as the strength and stiffness of the connecting parts of each structural member are insufficient and the stability is poor, resulting in the failure of structural members or connecting parts; or there are no reliable anti-loosing measures at the fastening parts of rotating parts, resulting in fastening failure.
