Property insurers know that fire is one of the most serious risks to commercial and residential properties, people, and communities. A March 2017 report by the National Fire Protection Association (NFPA), Fires by Occupancy or Property Type, provides interesting details on property damage from fires from 2010 to 2014, fueling the discussion on fire losses and trends for insurers and fire service professionals.
Detailed picture of property fire damage
The report offers a detailed picture of property fire damage, by percentages, in each of three major areas: structure fires, vehicle fires, and outside/other fires. It also delves into the causes of fires. The complete report can be downloaded from the NFPA website.
Some of the overall data points from the report show that fire departments in the United States responded to an average of 485,770 fires annually from 2010 to 2014. Each year, on average, fires caused $9.7 billion in property damage—as well as 2,716 civilian deaths and 14,651 civilian injuries.
Not unexpectedly, the report reveals that residential fires account for the greatest number of fires at just over 79 percent, as well as the largest property loss overall at nearly 73 percent. Commercial property losses were much lower by percentage. This is how they broke down by property type:
- mercantile: 7.4 percent of property losses, 3.5 percent of fires
- storage: just over 6 percent of property losses, 4.4 percent of fires
- manufacturing: 5 percent of property losses, 1 percent of fires
- total: 18.4 percent of property losses, 8.9 percent of fires
Although commercial fires are less frequent than residential fires, the property damage that commercial incidents cause is disproportionately higher, with losses in fires involving manufacturing properties five times higher. Understanding why commercial fires have such higher property damage and losses is important for property insurance underwriters to manage risk properly and set accurate premiums.
Analyzing the impact of commercial fire damage
U.S. Fire Administration (USFA) statistics on national data for 2015 indicate there were 104,600 recorded fires that year, with a total dollar loss of more than $2.6 billion. Forty-two percent of those losses were in fires resulting from the three leading causes of nonresidential building fires:
- unintentional or careless acts: $531 million
- electrical malfunction: $389 million
- other equipment malfunction: $232 million
USFA estimates for 2009 to 2011 show that nonresidential building fires represented only 6 percent of all reported fires, but they accounted for 22 percent of the total dollar loss from all fires. Nonresidential building fires also have a significant economic impact on a community because they may lead to job losses and business closings. Fortunately, one positive aspect is that the average number of fatalities and injuries per 1,000 nonresidential fires was notably lower than the same loss measures for residential building fires, possibly due to better fire evacuation procedures.
The lower frequency of nonresidential building fires may be due to several factors. First, stricter fire code enforcement often requires inspections of nonresidential buildings. Such inspections are not as prevalent for residential buildings, especially one- and two-family dwellings. Better code enforcement has been proven to help prevent fires. In addition, occupants of nonresidential buildings are usually awake and alert during all hours of the day and are better able to identify incidents and quickly act to prevent a fire.
There are several reasons nonresidential buildings may also suffer higher property losses. Commercial structures are often larger than residential dwellings and therefore more expensive. Contents are more likely to have a higher value because such buildings are occupied by businesses with inventories to sell, manufacturers with equipment, and other entities with valuable contents. Occupants that include cooking facilities were the leading cause of nonresidential building fires, at 29 percent, but nearly all cooking fires (97 percent) were small, confined fires with limited damage.
Properties that host public assemblies are considered high-risk. An assembly occupancy is generally defined as used for a gathering of 50 or more people for deliberation, worship, entertainment, eating, drinking, amusement, awaiting transportation, or similar uses, or used as a special amusement building regardless of occupant load.
Commercial, nonresidential properties such as nightclubs, theaters, and auditoriums feature large crowds in one main space. Cities and counties generally mandate a considerable number of safety systems and features for these buildings.
Ignition sources for “controlled” fires (fires in restaurants or flame used for dramatic effects in theaters) are well documented as causes of fires, and controlling them is of critical importance. Furnishings and contents are another risk, and questionable material should be removed or treated with approved flame retardants. Automatic sprinklers are highly recommended to help compensate for these risks, as well as fire alarm systems and portable fire extinguishers.
Other nonresidential properties
According to the NFPA, from 2009 to 2013, fire departments responded to an estimated average of 5,100 structure fires in educational properties annually, which accounts for 1 percent of all structure fires. Educational, health, and correctional facilities are often operated by the state or municipality and likely have better and more stringent fire codes.
Fire codes have been in place for decades, seeking to limit damage, injury, and loss of life due to fire in high-occupancy buildings. Schools are especially vulnerable because they house children. Depending on jurisdiction, the fire marshal or fire chief is responsible for educating and enforcing fire code regulations—requiring the codes and tips for preventing, containing, or escaping a fire to be posted prominently.
What are insurer takeaways?
What can insurers learn from this discussion on fire by occupancy and property type? Obviously, the more you know about the risks for property coverage, the better you can underwrite that risk. Knowing the differences between residential and nonresidential properties can inform policies and premiums, making sure insurers appropriately price customer coverage.
However, insurers may also want to consider being active in the fire protection discussion. You can be a strong voice for improved fire protection in communities, more effective fire and building codes, and better code enforcement.
