I have been working in 1 project about conveying system for Sulphur in Sulphonation plant.

I have been checking for some information about assessment due to combustible dust / flameable gas due to this work.

I am looking from NFPA 655 what things need to be checked to prevent & protect for fire&explosion in handling Sulphur.


So basically Sulphur (solid phase with small particle size) is dumped to conveyor (dump station) then it conveys to next meter tank where the Sulphur feeded by gravity to the tank (due to different level).


Hazard area classification has been discussed. 

I am working for fire & explosion prevention, protection and isolation.


Anyone have past experiences / current work ?
