Echo what Craig said. From memory I believe that one trigger is over 40ft and enclosed. In that condition they are almost always covered. As others have said there is some ambiguity here but the underwriter usually has the most input.

Belt material - combustible or non-combustible Enclosed or open - enclosed are almost impossible to fight with hose stream attack if not protected internally. High elevation - again, another hose stream and access issue. Value and importance to client - if the conveyor is handling combustible material and/or is of a combustible composition, and/or is of high value to the overall production of the plant site then it should be protected. Ask this question, if the conveyor was destroyed, would it significantly impact production? Any Underwriter requirements? Any local AHJ/FD requirements? Any owner Loss prevention requirements? There is plenty of data between NFPA and FM on how to protect them. The IFC has some direction for requirements of various types but not all types. These are some of the questions I'd be asking the client and other in order to make that determination if your particular conveyor type isn't mentioned in the IFC. Craig L.
