What depends on the use of approved practices, safety devices, and common sense?

The emphasis on approved practices, safety devices, and common sense directly correlates with accident prevention within the aerospace industry. This is because maintaining safety in assembly and maintenance processes is paramount to ensuring that all operations are conducted without hazards or risks to personnel or equipment.

Using approved practices helps standardize processes, thereby reducing the likelihood of error and incidents. Safety devices are implemented to provide additional layers of protection, further minimizing risks. Common sense plays a crucial role in decision-making, where individuals assess situations and apply practical judgement to prevent unsafe actions.

Together, these components form the foundation for a safe working environment, significantly contributing to accident prevention. This focus on safety is critical, especially in the aerospace sector, where the implications of accidents can be severe. It's also notable that while equipment efficiency, material selection, and training effectiveness are important aspects of aerospace operations, they don't directly rely on the same combination of safety practices as accident prevention does.
