Car ignition causes and fire precautions

Automobiles have become one of the most essential means of transportation in modern society. With more individuals owning vehicles, the risk of car fires has also increased. In addition to fuel systems and engine components, other parts such as tires, interior decorations, and electrical systems can also be flammable. Vehicles are equipped with various power sources, which can lead to fires if not properly maintained.

In the past two years, nearly 40 car fires were reported in Qiyang County, with the main causes including electrical faults, oil system failures, and mechanical issues. For example, on September 28, 2011, a heavy semi-trailer with the license plate Yu Henan K6497 caught fire on the Beijing-Shanghai Expressway due to bearing damage that caused the brake shoe to rub against the drum, leading to high heat and subsequent fire. Another incident occurred on July 12, 2012, when a truck with the license plate Su NQ2190 caught fire due to an electrical short circuit. These incidents highlight the importance of regular vehicle maintenance and safety awareness.

Primary Causes of Car Fires

Driving-Related Fire Causes:

1. Damaged oil pipelines can cause fuel leaks, which may ignite due to sparks or high temperatures. If the pipeline is not secured properly or is aged, it can rub against other parts, leading to wear and potential fire hazards.

2. Worn-out insulation on electrical wires can result in short circuits, increasing the risk of fire. Electrical systems are widespread in vehicles, making them vulnerable to damage over time.

3. Loose or damaged car parts can fall onto the road and ignite nearby flammable materials.

4. After repairs, items like gloves or rags left near the exhaust or engine can catch fire from high heat.

5. On roads with crops or grass, fast-moving vehicles can pick up debris that gets caught in rotating parts, causing friction and heat that may start a fire.

6. Smoking inside the vehicle, especially with unextinguished cigarette butts, can lead to fires.

7. Carrying dangerous chemicals without proper precautions can pose serious fire risks.

8. When transporting flammable goods, improper disposal of smoking materials or external fire sources (like chimney sparks) can trigger a fire.

9. Brake failure, where the friction plate overheats and ignites the tire, is another common cause of car fires.

Parking-Related Fire Causes:

When parked, fires often occur due to leftover embers, electrical shorts, or fuel leaks from the tank. It’s crucial to ensure the vehicle is in good condition before parking and to avoid leaving anything flammable in the car.

Fire Prevention Measures and Safety Tips:

1. Before driving, perform a thorough inspection of the vehicle, especially checking the electrical and fuel systems to prevent malfunctions while on the road.

2. When driving through areas with crops or grass, reduce speed and stay alert. Stop immediately if any unusual situation arises.

3. Never allow passengers to carry dangerous chemicals on board. If detected, take immediate action to ensure safety.

4. When transporting flammable goods, secure them properly and prohibit smoking by anyone in the vehicle.

5. Follow traffic rules strictly to avoid accidents that could lead to fires or explosions.

6. Vehicles entering fire-prone areas must be equipped with flame arresters. If a malfunction occurs, do not attempt repairs on-site; move to a safe location instead.

7. Always have fire-fighting equipment like extinguishers, fire blankets, and sand available in the vehicle.

8. During hot weather, avoid placing flammable items like lighters or perfumes in the driver’s area, as they can easily catch fire due to high temperatures.
