To prevent this from happening, Accident Data Recorders (ADR) can be used to record information over long periods of time. Due to their ability to be networked and the fact that many of these can be used to gather information about the same area (guaranteeing there is not a single point of failure if one fail), they can gather the most relevant information leading up to and after an accident. Similar technology already exists in different application areas but the lack of modularity, ability to network, and many other missing features makes them less effective at recording information. By recording all information relating to an accident, it can become much easier to understand how to prevent another accident in the future. This can not only save money but the lives of employees. https://ijoh.tums.ac.ir/index.php/ijoh/article/view/481 https://ijoh.tums.ac.ir/index.php/ijoh/article/download/481/652
