One of my favorite horror games! Don't know if you passed it already, but if it's chapter 10 Laura, you need to shoot the switches on the pipes in the ceiling when she's under them. Your goal is to get to the basement area and pull the lever to stop the fire and escape. She's tricky when you get down there since it's such a tight space so you need to evade her and try to catch her on fire with the switches while you wait, since after you pull the lever the fire will still go for a few seconds. This is all from my memory but I've played it a few times.
