Observe a Garbage Truck’s CNG Cylinders Detonate After a Lithium-Ion Battery Blaze

# **Explosion of Garbage Truck in Arlington Heights: A Warning regarding Lithium-Ion Battery Disposal**

A standard garbage pickup in Arlington Heights, Illinois, transformed into a perilous event when flames ignited in the rear of a garbage truck, culminating in a significant explosion. This occurrence, which took place on December 6, 2024, acts as a powerful reminder of the dangers linked to the careless disposal of lithium-ion batteries.

## **The Event: A Daily Fire Becomes Disastrous**

While fires in garbage trucks are not rare, they are typically under control. However, this specific fire rapidly escalated beyond what was expected. The Arlington Heights Fire Department arrived within five minutes of the initial alert, discovering flames leaping five feet high from the back of the truck.

Firefighters readied themselves to douse the flames using water hoses, a standard approach for these situations. Yet, just four minutes after they arrived, the truck exploded with great force. The explosion injured several firefighters and police officers, caused damage to nearby homes, and scattered debris throughout the area.

## **The Role of Compressed Natural Gas (CNG) in the Blast**

The garbage truck operated on **compressed natural gas (CNG)**, held in five carbon-fiber-wrapped cylinders installed on the roof. These cylinders featured **pressure relief valves** intended to safely release gas when temperatures rose between 212° and 220° Fahrenheit (100°–140° Celsius).

In this instance, however, all the pressure relief mechanisms failed. Instead of safely venting the gas, the cylinders exploded due to the escalating pressure from the fire.

## **What Ignited the Fire?**

Following a two-month investigation, fire officials determined that the fire was **likely initiated by a lithium-ion battery improperly discarded in a recycling bin**.

Lithium-ion batteries, frequently found in smartphones, laptops, and power tools, can enter a hazardous condition known as **thermal runaway** when damaged or subjected to high temperatures. This leads to an uncontrollable rise in temperature, often surpassing **750° Fahrenheit (399° Celsius)**, which can ignite nearby materials.

## **Response from Firefighters and Challenges Faced**

The truck was operated by **Groot**, a local waste management company. When the fire ignited, the driver attempted to put it out by compressing the truck’s load, a typical method to smother flames by cutting off oxygen. Unfortunately, this tactic failed, as the fire had spread too extensively.

Upon their arrival, firefighters directed the driver to **dump the burning load onto the street**, a tactic that could have reduced the chance of the truck’s fuel or CNG tanks catching fire. Regrettably, the fire had already compromised the truck’s dumping mechanism, making this action unfeasible.

Acknowledging the truck’s **CNG fuel source**, firefighters refrained from directing water onto the gas cylinders, adhering to best practices. Instead, they concentrated on extinguishing the fire in the cargo area of the truck.

They expected to hear the **hiss of the pressure relief valves** venting gas, which would have indicated that the safety devices were functioning. However, the valves never operated, and shortly after, the **CNG cylinders exploded violently**.

## **Lessons Learned: The Risks of Improper Battery Disposal**

During a recent **Arlington Heights Board of Trustees meeting**, Fire Chief Lance Harris stressed the significance of **proper lithium-ion battery disposal**.

Although the precise cause of the fire cannot be conclusively established, the investigation strongly indicates that a discarded **lithium-ion battery was the catalyst**. The fire’s intensity, rapid spread, and extreme heat were consistent with a **thermal runaway event** triggered by a damaged or punctured battery.

### **Guidelines for Safe Disposal of Lithium-Ion Batteries**

To avert similar occurrences, residents should adhere to the following recommendations:

1. **Avoid Disposing of Batteries in Regular Trash or Recycling Bins**
– Lithium-ion batteries should never be placed in household trash or recycling containers, as they can be crushed or punctured, resulting in fires.

2. **Utilize Designated Battery Recycling Programs**
– Numerous retailers, electronics outlets, and municipal waste facilities provide **battery recycling programs**.

3. **Properly Store Batteries Before Disposal**
– If you need to store used batteries prior to recycling, keep them in a **cool, dry area** and cover the terminals with **tape** to avoid short circuits.

4. **Adhere to Local Disposal Regulations**
– Consult your local waste management authority for appropriate disposal guidelines in your region.

## **A Near Miss and a Clarion Call**

Despite the explosion’s severity, **no major injuries** were reported among firefighters, police officers, or residents. However, the event underscores the **hidden hazards of improper waste disposal** and the **potential dangers linked to CNG-powered vehicles**.
