A good quality and safety system should identify and prevent the chain of errors at an early stage.The best defence for this will be to have experienced,well-trained,dedicated employees who understand the importance of safety and who follow procedures.The company culture must provide a positive climate to promote safety suggestions and especially listen to concerns about safety and how to improve operations.This means that the company really has to make the crew understand that they are doing and raise concerns through near misses and non-conformities.Safety is all about continuous improvement within the company and is a never-ending project.This could be implemented if companies adopt the MRM concept.
