Tire Fires

Tire fires, although infrequent, are serious situations that are difficult to extinguish and expensive to clean-up.
Tire fires often become major hazardous incidents affecting entire communities—frequently requiring neighborhood evacuations and long, drawn-out fire extinguishing operations. These fires threaten pollution of the air, soil, and water. EPA, states, municipalities, and private companies have spent millions of dollars cleaning up tire fires across the country.
EPA does not consider scrap tires a hazardous waste. However, if a tire fire occurs, tires break down into hazardous compounds including gases, heavy metals, and oil. The average passenger car tire is estimated to produce over 2 gallons of oil when burned. (Source: Rubber Manufacturers Association, April 2003)
Oil that exudes into ground and surface water as a result of tire fires is a significant environment pollutant. In some cases, this may trigger Superfund cleanup status. For every million tires consumed by fire, about 55,000 gallons of runoff oil can pollute the environment unless contained and collected. This oily material is also highly flammable.
Air pollution is also produced by tire fires. Air emissions may include polycyclic aromatic hydrocarbons (PAHs), benzene, styrene, phenols, and butadiene. For more information on toxic air pollutants generated by tire fires, go to EPA's Toxics Air Pollution Web site.
Notable Tire Fires
- In 1983, a 7-million tire fire in Rhinehart, Virginia issued
a plum of smoke 3,000 feet high and nearly 50 miles long with
air pollution emissions deposited in three states. The fire burned
for nine months, polluting nearby water sources with lead and
arsenic. The tire storage facility where the fire occurred is
now being cleaned-up as a Superfund site.
- In 1999, a lightning strike ignited a tire fire in Westley, California. The tire dump contained millions of scrap tires located in a canyon in a coastal mountain range. The large smoke plume from the fire impacted nearby farming communities and caused widespread concern of potential health affects from exposure to the smoke emissions. The tire fire also produced large volumes of pyrolitic oil that flowed off the slope and into the drainage of an intermittent stream. This oil was ignited too and the oil fire significantly increased the smoke emissions close to ground level. A response to the oil and tire fires was beyond the capabilities of local and state agencies. The EPA regional coordinator immediately responded using Oil Pollution Act of 1990 authority. It took 30 days to extinguish the fire. Total EPA response costs were $3.5 million.
Extinguishing Tire Fires
Waste tires are difficult to ignite, but once a tire fire starts, it is generally very hard to control and extinguish. Using water and/or foam to extinguish a tire fire is often futile. Water is best used to keep adjacent, unburned tires from igniting.
Smothering a tire fire with dirt or sand is usually the best option for extinguishing fires. Typically, the sand or dirt is moved with heavy equipment to cover the burning tires.
Putting out a tire fire can also be facilitated by removing unburned tires from the pile to lessen the fuel load.
Additional Information
Through EPA's Superfund Web site, users can search for National Priority List sites throughout the U.S., including those that have resulted from tire fires—such as the Rhinehart Tire Fire Dump Site in Virginia.
