AHJ

Authority Having Jurisdiction or AHJ

The AHJ as they are often referred to have a large portion of the control around what is and is not acceptable for your dust collection system.  The NFPA today serves as a set of guidelines for people to follow but leave quite a bit to interpretation.  

My recommendation would be to involve your local AHJ in some part of the process to ensure you are working toward a agreeable and safe solution for your employees and facility.  Examples of who your AHJ may be:

Insurance underwriter

Local Fire Inspector 

Building Inspector

In most instances the person and the level of understanding will vary from city to city and makes it very difficult to formalize a standard that can be adopted nationwide.  Through this blog i will tackle some of these topics and discuss my interpretation of these guidelines.

Thanks
