How Common Are Shipping Hazmat Spills?

Hazardous materials are defined as any materials or substances that, when involved in an accident or misused and released in sufficient quantities, pose a serious risk to property and the health and safety of people. They may be poisonous, explosive, corrosive, flammable, radioactive or otherwise toxic. Because they are commonly used in numerous industries, the shipment of hazardous materials is common. While there are numerous regulations in place, accidents still sometimes occur during shipment. Hazmat spills that occur during shipment most commonly occur as the result of transportation accidents. Just how common are these types of spills during shipment? Let’s take a closer look.

Common Types of Shipping Hazmat Spills

Millions of tons of hazardous materials are transported throughout the United States every single day. In fact, the U.S. DOT Pipeline and Hazardous Materials Safety Administration estimates that there are more than 800,000 hazmat shipments every day, and more than 3.1 billion tons are transported each year. While most carriers deliver their cargo to the intended destination without any problems, accidents do occur from time to time. Most of these accidents involve incidental releases that do not pose a major threat to people or property, but some spills result in a more serious threat.

Hazardous materials are also commonly shipped via railway, and incidents like train derailments can result in massive hazmat spills that can be devastating to the environment and post serious risks to human health and safety.

When a hazardous materials cargo spill occurs, a material or substance that could post a risk to health, safety or property is released. There are several factors which dictate the size, nature and severity of the spill, including the type of material being transported, the physical properties of the hazardous material, the volume of the original load and the amount of damage sustained by the transporting vessel.

The most common types of hazmat shipping spills include flammable items–combustible liquid, corrosive material, nonflammable compressed gas, oxidizer and poisonous materials.

Frequency of Hazmat Spills During Shipment

According to the Federal Motor Carrier Safety Administration  (FMCSA), the rate of hazmat carrier crashes, injuries, fatalities and spills is low in comparison to the overall amount of hazardous materials transported along U.S. highways. Though not extremely common,  hazmat spills come at a significant cost. They have a major impact on the economy and can cause significant property damage.

The United States Census Bureau estimates that hazardous materials make up approximately 11 percent of the freight transported by trucks in the U.S., and the U.S. Department of Transportation estimates that hazardous materials are carried in about 7 percent of all trucks. While hazmat transportation makes up a significant portion of the type of material being transported on U.S. roadways, crashes and accidents involving hazardous materials are under-represented in overall accident statistics.

In 2017, the U.S. DOT Pipeline and Hazardous Materials Safety Administration reported a total of 3,391 incidents of hazmat spills during transit. These incidents resulted in two hospitalizations, six fatalities and $32,806,352 in damages. Spills are much more likely during unloading. Incidents during the unloading phase of transportation resulted in 8,036 incidents. The damages incurred during unloading incidents, however, only totaled $4,976,052.

Spills are much less common when hazardous materials are shipped by railway. In the same year, there were only 431 incidents that occurred while hazardous materials were in transit by train. These incidents resulted in no fatalities and $19,214,653 in damages. Hazmat spills when materials are transported by train occur most commonly during transit with only nine incidents occurring during unloading.

A Final Word

There are numerous laws and regulations by which hazmat carriers and shippers must abide. They are constantly evolving to address current needs and situations. Together, these laws and regulations are intended to make shipping the billions of tons of hazardous materials needed in several industries as safe as possible. Accidents can occur in any business or industry, but due to the potential severity of accidents involving hazardous materials, there are strict guidelines to make transport as safe as possible.

Using the proper shipping containers is one of the best ways to prevent leaks and spills during shipment. It is also vital to properly label all containers as well as the vehicle in which the materials are being transported. Make sure all employees are well-trained on how to safely transport hazardous materials and take steps to ensure that proper procedures will be followed in the event of an accident. While not all accidents can be avoided, taking proper precautions greatly reduces the risk of hazmat spills during shipping.
