Fire blankets - do they work? worth having one in the kitchen?

Yes, so much this. I recently witnessed a ‘kitchen fire’ that was not handled well. Some food finished baking so the oven briefly was briefly set to broil to finish the cook.

Never mind the oven is a pretty safe place to keep fire. Or smoke. Or a few ash particles. And the broiler raging 3 inches above where you’re reaching/grabbing at is far hotter.

I thought it was for clothing/hair/‘hair’ fires, iconically demonstrated in this clip:
