Fact Sheet #608
Barn fires are a farm owner’s worst nightmare. Most have tragic results
such as the loss of human life, animals, valuable equipment, or the
building itself. The National Fire Protection Association (NFPA)
estimated that during the period 2002 - 2005, an estimated 1,090
structure fires in livestock, poultry storage, barns, stockyards, and
animal pens were reported to municipal fire departments annually.
These fires resulted in two civilian fire deaths, ten civilian injuries
and $32.4 million in direct property damage, annually; the number of
animals lost in these fires is not reported.
Insurance statistics show that the two most common times of the year for
barn fires are summer and winter. Summer fires are often the result of
electrical storms or spontaneous combustion of hot hay. Winter fires are
caused by appliances, rodents chewing through wires, or the accumulation
of dust and cobwebs on electrical surfaces. Heating equipment is the
leading cause of fires in barns with heat lamps as the leading heating
equipment involved in these fires.
Barn fires are not small. Half of barn structure fires involve the
entire building. Forty-eight percent of barn structure fires occurred in
the Midwest and thirty-two percent occurred in the South in 2002 - 2005
(Flynn, 2008). This fact sheet will explain to horse owners and others
the short and long term precautions that should be taken to help reduce
the incidence of barn fires. Farm owners and managers should be able to
identify potential fire hazards around the farm:
Highly Flammable or Combustible Materials - If at all
possible, hay, straw and other types of bedding should not be stored in the
same building in which livestock is housed. Care should be taken that these
materials are not stored with machinery or near any type of electrical or
heat source. Highly flammable materials may include:
Once hay is stored, it is important to monitor the temperature to determine
if the hay is at risk for spontaneous combustion. The Humane Society of the
United States suggests inserting a thermometer into the middle of the stack
to check the temperature of the hay. If it reads higher than 150 degrees
Fahrenheit, the hay needs to be checked regularly. If the temperature climbs
to 175 degrees Fahrenheit or higher, call the fire department.
- Hay and straw
- Bedding material (especially sawdust and shredded newspaper)
- Cobwebs, dust, and grain dust
- Horse blankets
- Pesticides and herbicides
Accelerants - Accelerants are substances that increase the speed
at which a fire spreads. All accelerants are highly flammable or
combustible, but not all highly flammable or combustible materials are
accelerants. Accelerants must be stored in approved containers and properly
labeled as such (plastic milk bottles do not qualify as approved containers
for storing chemicals). An updated list of all chemicals on the farm should
be maintained. The list should include the name of the chemical, date
purchased, the quantity of the chemical, and the place of storage on the
farm. This list should be kept in a safe, handy place such as a farm office
(not in the building where the products are stored). In some states and
municipalities an inventory and location of accelerants on the farm may need
to be on file with local authorities and be just given to the fireperson in
charge to aid the fire department in knowing what potential toxic fumes or
explosions may result and how to most effectively contain the situation.
Common accelrants include:
- Aerosol cans
- Paint thinner
- Charcoal lighter fluid
Ignition Sources - An ignition source is something that can cause
an accelerant or flammable material to ignite or smolder. Examples of
ignition sources are:
Roadways and Farm Access
- Cigarettes and matches
- Sparks from welding machines and machinery (trucks, tractors, mowers)
- Electrical appliances
- Fence chargers
- Electrical fixtures and wires
- Broken glass
- Chemicals which may react with each other or with water or dampness
- Roads and driveways should
be wide, free of deep ruts and bumps.
- Low hanging tree branches
and shrubs should be trimmed back.
- Gates should be wide enough
for machinery and trucks, and set far enough back so that vehicles are off
the main road when stopping to open or close gates. Overhead wires should be
high enough for trucks, trailers, tractors, and other equipment to pass
- There should be 10-foot wide
fire/emergency lanes around all buildings and structures.
- Vehicles should only park in
designated areas to keep roadways open for emergency vehicles.
- Vehicle and trailer parking
should not be permitted next to barn/stable.
- Vehicular traffic should
proceed slowly and with caution.
- Speed limit signs of 15 mph or
lower should be posted and enforced. “Caution: Horse Crossing” signs are
available through many retailers.
When constructing a new building in which to house horses
and/or livestock, precautions should be taken to reduce the chance of barn
fires. Many of these measures are required by the township’s building code.
Always check with the town building inspector’s office for the requirements
and permits necessary in your area. Many insurance companies will lower
premiums if extra fire safety precautions are taken during the construction
of a new building, some of which may be above and beyond the standards
required by the township. Check with industrial insurance companies
regarding which features will possibly lower insurance premiums. Extra
measures may include:
Electrical Systems and Devices
- Limiting the number of stalls in a center aisle barn between entrances
and exits; consider putting an entrance/exit midway down a row of stalls,
- Use of approved fire doors.
- Placement of a fire wall between hay/bedding storage and the actual stabling area.
- Use of materials that are flame retardant or fire resistant.
- Use of fire retardant latex paint - preferably two coats.
- Installation of smoke detectors, fire alarms, and sprinkler systems - all of
which can be monitored by local police or fire departments.
- Use of trickle-charged battery powered emergency lighting to permit evacuation
of people and animals in case of power failure.
- Presence of a water source on the premises, especially a pond, will help the fire
department to save buildings. Trucking in water from a distance if a water
hydrant is not available is time-consuming. Remember to have the water
source properly fenced to keep “unwanted” visitors out.
Electrical systems in barns, especially in older structures, are often
the cause of a barn fire. The following safety precautions (sometimes beyond
the township electrical code requirements) should be taken when installing a
new system or repairing older electrical systems.
- Avoid areas of excessive moisture for the location of the main electrical panel box.
- Place panel box in the driest, most dust free area possible. (Stall areas are
not recommended; place in tack room or utility room.)
- Panel box should be corrosion-resistant and weather-proofed even if
installed inside a building.
- Outlets and switch boxes should be made of metal and have dust- and
water-tight spring-loaded covers that close when released. Ground
fault receptacles should be utilized for all outlets.
- Wires should be encased in metal conduit pipe. Even temporary wires
(such as extension cords to a tank heater) should be run through conduit
pipe to keep the wires safe from breakage and away from the teeth of
horses, livestock and rodents, and shoes of horses. An external
switch should be installed that will cut off all electrical power to the
barn, without affecting other buildings, in the case of an emergency.
- Light fixtures, fluorescent lights, and insect control devices should have
dust- and moisture-resistant covers. Incandescent bulbs should have
gloves with seals that are dust- and moisture-proof, surrounded by a globe
cage to prevent accidental breakage.
- Motors -- such as the type used for circulation fans, water pumps or hay
elevators should have moisture- and dust-proof on/off switches.
- Motors should not be within 18 inches of any combustible material such as
hay or bedding. A fire-resistant shield should be placed around such
material to protect it from any heat given off by a motor.
- Electric fence units can be potential fire hazards, especially if the units are
of the continuous current type. Use only UL listed units that are of the
solid state transistor-type, with intermittent current. Fence-line units
should be 10 feet from buildings and enclosed in a weather-proof structure.
- Any appliances used in the barn (e.g. clippers, dryers, vacuums) should be
UL-approved and grounded. Appliances with broken, frayed cords or bent
plugs should not be used until properly repaired. (Wrapping the cord in
electrical tape is not a proper method of repairing a frayed cord.) All
appliances should be disconnected when not in use.
- Portable heaters should not be used in the barn area. If they are used in
tack rooms, heater units should not be left unattended and should be
turned off when you leave the room. Many of these heaters do not contain
safety devices, which prevent overheating.
- Do not place portable space heaters near livestock where they may be
knocked over. Heaters should have a shut-off device that activates if
the unit is tipped.
- Improperly utilized heat lamps are a major source of barn fires. They are
often placed too close to hay and bedding which may ignite quite easily
from the heat. Never use extension cords with heat lamps.
- Heat tapes, heated automatic water tanks, and water tank heaters must have
a thermostat and be UL listed. All heating devices should be installed and
used following manufacturer instructions. Tank heater cords and heat
tapes should be adequately protected so that animals (horses, livestock,
cats, dogs, rodents) cannot easily chew through them and cause
electrocution, electrical shocks or a barn fire. Heat tapes should be
protected with a fire-retardant insulation material.
General Fire Safety Precautions
- Smoking should never be permitted in any barn, hay/bedding storage area,
tack room, or lounge. "No-Smoking" signs should be posted in these areas
and at all exterior entrances. Butt cans should be provided as an incentive
to extinguish all cigarettes.
- Exit doors should be clearly marked.
- Aisles should be raked or swept clean of hay and bedding. Vacuum up
cobwebs and dust regularly. Wipe dust/dirt off light fixtures, outlet covers,
switches and panel boxes.
- Weeds, twigs, and other trash should be kept mowed or picked up from
around the outside of the barn.
- Manure piles should be at least 20 feet away from the barn to reduce the
chance of combustion fire.
- Hay/bedding storage should not be near lights, fans, electrical boxes,
heaters or outlets.
- When storing newly baled hay, the temperature should be
monitored. Adequate ventilation should be provided for additional drying
of the hay. If too much heat builds up, spontaneous combustion can occur.
(Never purchase hay that is hot - because it can mean that it was baled too
wet. In addition to being a fire hazard, the hay may turn moldy, making it
unpalatable and unhealthy for horses to eat.)
- Flammable substances should be kept away from the barn.
- Store vehicles and machinery in a separate building.
- If a vehicle is being driven through the barn, during stall cleaning for
example, care should be taken not to block horses in stalls.
- A halter and lead shank for each horse should be hung on all stall door
fronts in case of an emergency.
- A fire hose and buckets should be available and kept for this purpose only.
- Practice fire drills should be held so employees and boarders are familiar
with their responsibilities should a real fire occur.
The Lightning Protection Institute estimated that 41 percent of 250 lightning-related
equine deaths were not the result of horses being struck directly, but were due to
horses being asphyxiated or burning in barn fires caused by lightning.
- Buildings should be equipped with professionally installed lightning rods
of copper or aluminum. The system should be properly grounded.
- All pipes, water systems, electrical systems and telephone lines should
also be grounded.
- Contact a professional company for proper maintenance and installation.
- Information on proper lightning precautions for your livestock structure
can be obtained from the Lightning Protection Institute, www.lightning.org.
- ABC (all class) dry-chemical fire extinguishers should be in all livestock
buildings, workshops, or wherever welding is done.
- The extinguisher should be 5 lbs. minimum. 10 lbs. is ideal.
- Even if a unit is only partially discharged, the extinguisher must be recharged.
- Extinguishers should be checked at least annually to
assure that they are in good working order.
- A fire extinguisher should be hanging at all exterior doorways, in the
middle of long aisles, and next to the electrical panel box.
- Signs denoting placement of fire extinguishers should be highly visible.
- Consider covering fire extinguishers with a luminescent
cover clearly marked “FIRE.”
Smoke Detectors for Livestock Buildings
Early fire detection systems may give you enough time to get livestock out and maybe
save the building. Heat and smoke detectors are available for livestock facilities. The
detectors should be professionally installed to guarantee that they are in the most
effective location within the barn. Sirens or bells should be loud enough to be heard
from a distance, in case no one is in the immediate vicinity of the barn. The alarm
should go directly to the fire department alerting them that there is a barn fire and live
animals and/or humans might be involved.
What not to do!
Never fight a fire if it is already large and spreading.
Never fight a fire that could spread to block your escape route.
Never fight a fire if you have not been trained to properly use a fire extinguisher.
