it is...the entirety of fire marshal and firefights laws being replaced by just 4-5 rules would save countless lives:

- build secondary escape doors and don't lock/block them

- have smoke detectors in every room

- have fire extinguishers in every building, and for large buildings for every 200sqm or so, and every floor.

For large commercial spaces, add sprinklers.

These are bare minimum things, but it would be better than what it's like today. And from there, they could slowly add more rules where it makes sense, and shutdown whoever is not implementing these.
