I arrived to do a Semi-annual fire suppression inspection & testing. This was for a Range Guard kitchen system. I did a quick site survey to make sure that everything looked good. I then started the testing and inspection of the Range Guard system. I removed the fusible links and put new ones in. I wrote the inspection report out and emailed to the customer. I then let the manager on site know that I would call in 6 months to get them back on the schedule as it is the requirement of the Fire Marshal and the codes governing the system.
