upon moving into my new apartment, the first thing i purchased to furnish it was a fire extinguisher, which is currently hanging neatly just adjacent of mt front door. as someone who's lived in college-town houses run by absolute slum lords for the better part of a decade, i've ran into my fair share (to put it lightly) of situations that could have ended up being massive fire hazards. an electric cable right next to a corner of the house that's seen considerable water damage that no one's gonna do anything about since your landlord is a cheapskate and you're broke as fuck, an electric stove where one of the burners isn't connected right and that somehow causes sparks to fly around smack dab next to wherever the closest adjacent electrical outlet is whenever your roommate tries to heat up some soup or something and forgets that he's using the burner everyone told him not to, a roommate walking into your house drunk as all hell and then making some macaroni but then falling asleep on the couch halfway through... there's just so many situations you, as a person no matter what walk of life you're on, could easily solve (or at least maybe ameliorate) if you had a fire extinguisher at the ready at all times.
