Often times we get so involved with meeting OSHA and EPA regulations that it is easy to loose site of the State Fire and Hazardous Material codes. In some states these codes can be even more stringent that OSHA and EPA process safety requirements! PLEASE keep in mind, each state will have their OWN SET of fire and HAZMAT codes, but in this article I will be using the Ohio Fire & Hazardous Materials codes. This will give everyone an idea as to what their state codes could require and for those with facilities inside the state of Ohio, this article will provide much of what would be required. I have even posted the state requirements for Ammonia Refrigeration processes.
