Never have more than two cooks in the kitchen, otherwise it's a fiasco. Don't be selfish. Keep An Eye On The Stove. Better yet, keep both eyes on the stove. Because it can happen.
Unattended cooking leads to fires.
Cooking is not the time to wear your new fancy shirt with the bell-bottom sleeves. Loose clothing can catch fire if exposed to heat sources. You get the drift. Prepare for safety. Keep children away from the cooking area.
