Defective Fusee Striker Caps 2019

During a “Firing Device Demonstration” at this S-390/190 Field Day, the instructor attempted to light a fusee to demonstrate the correct procedure for students. But the fusee would not light. Initially it was believed that these fusees might have gotten wet or been defective. After further examination, it was determined that the fusees would light with a striker from a different batch of fusees. The investigational method was to attempt ignition of each defective fusee by use of the original striker cap, followed by a striker cap of the same style, followed by a striker cap off of a different type of fusee. Neither the original cap or other identical caps would light any of the defective fusees. However, all defective fusees that were tested successfully ignited on the first attempt with a different style of striker.
