内向性

对于生产事故来说，造成这些事故的主要原因通常均和生产系统有关系，所以为企业内部系统因素，比如相关机械设备没有安全防护、设备改造没有按照相关标准、设备检修过程中没有安全措施等，而对于那些外部系统因素（比如天气状况以及自然灾害等）来说，对中小型制造企业的安全生产所造成的影响很小。

For production accidents, the main causes of these accidents are usually related to the production system, so there are no internal safety factors for the internal system factors, such as related mechanical equipment, equipment modification, no safety measures, etc. For those external system factors (such as weather conditions and natural disasters), the impact on the safe production of small and medium-sized manufacturing enterprises is small.
