Leave the windows open (for gas escape); Have a fire extinguisher near by (for food caught on fire); A fully charged phone (to call for help)... And make sure the smoke alarm is in working order (it is louder than your shout)... and lastly check if you have paid your insurance. Don't laugh...these were true advices when I said I am going to cook for the first time.
If children in the home, keep them out of the Kitchen when hot things abound!
I was so 'thingy' about this I had an aluminium lockable grille, as my kitchen 'door' whilst kids were little. They could 'look in & see', but we're NEVER in any DANGER!
It was dismantled once they middle-yeared teenagers!
