Sure, but at some point, you have to be told what "duck, cover, hold" actually means. Your comment as the first comment someone hears is like a news article using acronyms throughout the article without ever expanding the acronym.
In California, even saving yourself from being on fire is taxed.
I guess my fellow Californians can be a little touchy about taxes.
I'm still not sure what I'm supposed to be holding onto. Do I briefly cover my head with my arms, then stop covering my head to hold onto the table? Do I hold onto my head while I cover it? Do I cover my loved one's head and they cover mine, sharing our last moments in a loving hold?
Now I'm beginning to wonder if I made a massive assumption that I would be covering my head with my hands. That's what I would do during a tornado, but maybe I'm supposed to be covering my head with a blanket so my hands are free for the hold on part?
Honestly, my facetious hold my bladder advice seems more apropos than anything I've managed to come up with for part three.
DROP or DUCK down to your hands and knees
Take COVER protecting your head/neck with an arm and crawl under a sturdy table/desk possible or to a nearby interior wall away from potential falling objects
HOLD ON to your shelter if you have it or head/neck with both hands if you don't
It's not as obvious as stop, drop and roll which is why drills are a thing in schools.
It's also not terribly far from duck and cover drills for nukes or tornadoes as I understand it. The hold on bit was added to keep people from tripping and breaking a leg while running around while the ground is shaking.
I grew up on the west coast and that's exactly how it was taught to us in public schools.
