A Fire Plan for an Old House

A fire plan for an old house starts with two things: working alarms on every level and a written escape route that ends at one meeting point outside. Everything else, extinguishers, generator placement, burn permits, is built on top of those two. The house itself decides the rest.

St. Augustine holds the oldest housing stock in the country, and old wood framed houses with coquina walls burn differently from new construction. A fire that starts in a wall cavity can travel inside a chase for minutes before any alarm sounds. That is why the plan has to assume less warning, not more. Residents who want the local version of this material, written for St. Johns County specifically, can read the Oldest City Fire Journal and compare its seasonal checklists against their own house.

Where do the alarms go in a house this old?

One alarm per level, one inside each sleeping room, one in the hallway outside the sleeping rooms. That is the floor plan the US Fire Administration repeats, and it holds in a 1790 coquina house as well as a 1990 ranch. The difference is placement inside the room. In a house with plaster walls and a high ceiling, smoke reaches a ceiling mounted alarm later than it would in a modern room with a lower ceiling. Mount the alarm on the wall, six to twelve inches below the ceiling, and it will sense smoke sooner in a tall room.

Replace the whole unit every ten years. The date is stamped on the back. Write that date in the house journal so the next owner does not have to guess. Test monthly with the button, and vacuum the vents twice a year, because dust from a plaster house settles inside the sensing chamber and causes false alarms at three in the morning.

Interconnected alarms are worth the wiring. When one sounds, all sound. In a two story house with a stairwell, that difference is measured in seconds, and seconds are the whole point.

What does an escape route look like in a narrow lot?

Draw the floor plan on paper. Mark two ways out of every room. In a historic district house, the front door and the side door are usually the two, but a second floor bedroom may only have one door and one window. If the window is the second way, make sure it opens. Paint the frame so it does not stick. Keep a chain ladder in the room if the drop is more than one story.

The meeting point goes at the street, not the yard. In a neighborhood of narrow lots and shared fences, the yard is not a safe gathering place. Pick a fixed object: the corner of the lot across the street, the base of a particular oak, the mailbox two doors down. Everyone walks there and stays there. Nobody goes back inside for a pet or a phone.

Practice the route at night, with the lights off. A plan that only works in daylight is not a plan. Walk it twice a year, once in spring before storm season and once in fall. Time it. If it takes more than two minutes from the furthest bedroom to the meeting point, find the delay and remove it.

How do you handle a generator after a storm?

Generators run after every named storm in this county, and they cause a predictable set of fires. The rules are short. Never run a generator inside a garage, a screened porch, or a carport, even with the door open. Carbon monoxide kills before fire does. Place the unit outside, at least twenty feet from any window, door, or vent, and point the exhaust away from the house.

Store fuel in an approved container, capped, in a detached shed, not in the house and not in the garage. Let the generator cool before refueling. A hot muffler ignites gasoline vapor in under a second.

If the house has a transfer switch, use it. If it does not, run extension cords rated for the load, and never backfeed a dryer outlet. Backfeeding sends current onto the lines where a utility crew may be working.

When is a burn permit required?

In St. Johns County, outdoor burning of yard debris requires authorization from the Florida Forest Service, and the rules change with the drought index. A pile of oak limbs is not a campfire. Check the current burn status before lighting anything, and keep a hose charged and a shovel within reach. Never burn on a windy day, and never leave a pile unattended, even for a few minutes.

Inside the city limits of St. Augustine, open burning is generally prohibited. Compost or haul instead. If a neighbor is burning illegally, the county non emergency line is the right call, not a confrontation across a fence.

What changes with the seasons here?

Spring brings pollen and dry afternoons. Clean the dryer vent, because lint in a hot duct is the most common appliance fire in any housing stock. Check the lint trap housing with a flashlight, not just the screen.

Summer brings thunderstorms and lightning. A strike on an old roof can smolder in attic insulation for hours. If a storm passes and the house smells like scorched wood, call the fire department, not an electrician.

Fall brings hurricane season's tail end and the generator questions above. Winter brings space heaters and candles during outages. Keep heaters three feet from anything that burns, and use battery lights instead of candles when the power fails.

Who checks on the neighbors?

A fire plan is not only for the people inside one house. On a block of older residents, the useful habit is a short list: who lives alone, who has a mobility issue, who needs a knock on the door when the power goes out. Two minutes of checking is worth more than any device.

Parents who host a sleepover should ask two questions before the night starts: where are the exits from the room the children will sleep in, and does the visiting child know the meeting point. Write it on a card and leave it on the kitchen counter.

For anyone considering the work itself, St. Johns County fire departments recruit from the community, and the path starts with a physical test and a state certification. The local editorial coverage of that process, along with alarm guidance and burn rules, is collected at the Oldest City Fire Journal, which publishes for residents of the city and the county.

The plan is one page. The alarms are ten year devices. The meeting point is a fixed object at the street. Everything else is maintenance, and maintenance is what keeps an old house standing.
