Chicken Coop Fire Safety: The NFPA Tip Sheet Explained Point by Point

Why a coop burns so easily

A backyard coop is a small wooden building filled with dry straw or shavings, feathers and dust. Into this building go one or more electrical devices, and with them live animals that flap, perch on things and knock them over. The University of New Hampshire Extension gives exactly these two reasons, combustible bedding and birds that knock things over, for advising against supplemental heat in most circumstances.

The Maine Fire Marshal's Office, quoted by the Bangor Daily News, names four top causes of coop fires:

Two things are worth noting. The list does not stop at heaters: the water side of winter care is on it too. And no source read for this site offers a national count of backyard coop fires, so we give none.

The NFPA tip sheet, point by point

The NFPA published its one-page safety tip sheet “Backyard Chicken Coop Safety” in 2018. It contains twelve tips and a short box on hay and bedding. Here is each tip with what it means in a backyard coop.

Tips 1 and 2: heat lamps

Secure heat lamps properly, and keep them away from anything that can burn. The sheet gives the reason for the first rule itself: a secured lamp cannot be knocked over. In a coop, “anything that can burn” means bedding, nest material, feathers, wooden walls and cobwebs. The University of Maryland Extension warns that lamps can cause fires if they are not properly secured, and that cold water splashed on a hot bulb may shatter it. No extension service read for this site asks for a heat lamp for adult birds.

Tips 3 and 4: space heaters

Keep space heaters away from anything that can burn, and place them on a sturdy surface so they cannot be knocked over. These two rules apply to every heater in the coop, including a flat radiant panel standing on its feet. The floor is where the bedding is. A panel screwed to the wall at roost height meets both rules better than any free-standing device. How heater types compare on these points is the subject of the safest heater for a chicken coop. Two household heaters that readers ask about have short answers of their own: oil-filled radiator in a chicken coop and propane heater in a chicken coop.

Tip 5: dust and cobwebs

Brush cobwebs and dust from light fixtures and outlets, and do it regularly. Chickens produce fine dust all year, and it settles on everything warm. Penn State Extension gives the same advice for barns and extends it to wiring and heating sources. For a coop heater this means: unplug it, let it cool and brush it off as part of the weekly routine.

Tip 6: covered bulbs

Choose light bulbs that have covers. The sheet names three things a cover keeps away from a bulb: dirt, moisture and breakage. This matters for keepers who light the coop to extend the laying day. The University of New Hampshire Extension recommends LED lamps for that purpose because they generate little heat.

Tip 7: extension cords

The shortest rule on the sheet is also the one most often ignored: “Do not use extension cords in the coop.” The Maine Fire Marshal's Office describes what goes wrong: cords are laid under boards or directly over straw, get kinked or split open, and become a fire hazard. Its advice is to run any wiring into the coop in conduit. A fixed outlet at the coop is therefore the first purchase, before any heater or heated waterer.

Tip 8: equipment for agricultural or commercial use

Choose electrical equipment made for agricultural or commercial use. A household clamp light or an indoor space heater was not built for dust, moisture and animals. In practice the rule points to devices that are sold for coops and barns and that carry a listing mark on the device itself. Home-built heaters run into the same rule; see DIY chicken coop heaters. A ceramic emitter in a lamp socket is covered under ceramic heat emitters.

Tip 9: heated waterers

Be careful with electrically heated poultry waterers, and make sure the cord and plug are properly grounded. This is the only tip that names a product type. Ohio State University Extension notes that heated water bowls or containers may malfunction and cause a fire. The University of Maryland Extension asks that a heated base neither melt the container on it nor start a fire if it comes in contact with litter. A heated waterer belongs on a level, raised spot clear of loose bedding.

Tips 10 to 12: wiring, electricians, outlets

Check all wiring for damage. Have electrical work done by a qualified electrician. Choose outlets and switch boxes designed to keep out dust and water. Rodents chew cords, and chickens peck at them. Ohio State University Extension asks that the electrical feed to the coop be sturdy, safe and out of reach of the birds. Penn State Extension recommends inspecting wiring, junction boxes and panels once a year. This site gives no wiring instructions. That is the electrician's job.

The box on hay and bedding

The sheet closes with storage advice: keep baled hay away from the animals, and keep hay and bedding stores away from anything that can burn. It also suggests asking your community about rules for animal housing and talking to the local fire department about any fire concerns. A spare bale of straw does not belong next to the outlet or under the heater.

What the tip sheet does not say

Three popular claims go further than the sources do.

• A temperature for heat lamp bulbs and an ignition time for bedding. Figures circulate on blogs and in chatbot answers. We found no fire authority or laboratory that published them, so this site gives neither.
• A fire statistic for backyard coops. The tip sheet contains no numbers. Local reports exist; a national count for coops was not found.
• That a panel heater solves the problem. A manufacturer advertises its coop panel as safer than heat lamps. That comparison is fair. It does not remove the bedding, the dust or the birds from the equation, which is why the University of New Hampshire Extension still advises against heat in most circumstances.

A winter routine built from the twelve tips

1. Before winter

   Have a qualified electrician install or check a fixed outlet at the coop, in a box designed to keep out dust and water. Check every cord for chew marks and cracks.

2. When you set up a device

   Mount heaters firmly and off the floor, hang or stand heated waterers clear of loose bedding, and plug each device into the fixed outlet with its own grounded cord. Follow the manufacturer's instructions for clearances.

3. Every week

   Brush dust, feathers and cobwebs from heaters, fixtures and outlets. Look at the cords while you are there.

4. Every day

   When you check the water, glance at each device: is it still where you mounted it, is the bedding still clear of it, does anything smell hot?

5. After winter

   Unplug and store heaters and heated waterers dry. A device that runs all summer collects dust for nothing.

Does your coop need the risk at all?

Every rule above manages a risk that starts with plugging something in. The extension services disagree on whether adult birds need heat, and all of them put a dry, draft-free, ventilated coop first. The two camps are laid out under do chickens need heat in the winter. Good chicken coop ventilation needs no electricity and adds no device to the coop.

Liquid water is the one winter need that often does call for a device. If you decide to heat the coop as well, how to heat a chicken coop walks through the order of work, and the overview of all heater types is on the chicken coop heater home page.
