Wealth on Instagram: "A closed door doesn’t stop a fire, but it fundamentally changes how fire spreads through a structure 🧯🧠 Fire growth depends on oxygen, airflow, and heat transfer. When a door is closed, airflow into the room is restricted, limiting flame spread, reducing temperature rise, and slowing the movement of toxic smoke into that space. This doesn’t create a permanently safe room. Smoke inhalation is still dangerous over time. What it does create is delay. Delay in heat buildup. D
