serviced a vehicle fire suppression system on a construction site where the operator reported a warning light indicating a possible system fault. Upon inspection, I found that one of the detection lines had been damaged, likely from heavy equipment movement, which caused a drop in pressure and triggered the alert. I safely depressurized the system, replaced the damaged detection tubing, and recharged the system to the proper levels. I then tested the unit to confirm proper functionality and ensured the control panel was reset. The vehicle’s fire suppression system is now fully operational, and I advised the site supervisor on ways to better protect the lines from future damage.
