Senior law enforcement officials said the LASD bomb squad responded to a garage in Santa Monica yesterday, where at least one grenade was found. It was transported to the training facility, where the deputies were working to render it safe, and the explosion occurred.
From my experience most incendiary grenades don’t have a time delay either. They’re meat to be put on an item for destruction, pin pulled, and then leave. We used to set them off remotely by placing a blasting cap under the spoon after pulling the pin and taping down the spoon.
For use with trip wires or as a booby traps. Most grenades are designed to use a variety of fuzes.
