In order to face different occupational risk, different industries such as Aerospace, Chemical, Oil and gas, Railways, Nuclear has established standards guidelines. In fact, some of such standard is a guideline for all industries like OHASA 18001 which address the Safety and Occupational Health management or IEC 61508 which address the safety integrity level. By the other way round, the specific standard area applied to risk management in different industries like SCR05 which addresses risk management in oil and gas industry or the nuclear safety case that also focus on risk management. In general terms, all those standards are a good guideline to support safety and occupational management in different industries. Even though, it’s important to have in mind that such standards do not reflect the best practices to mitigate the risk in many cases. Indeed, the companies all over the word must to make all effort to apply the best practices to achieve high effectiveness in their safety and occupational management applying the standards as a baseline. This chapter aims to demonstrate the main standards applied to the most relevant industries in term of risk.
