Transportation - Pneumatics Insurance

Hauling flammable and hazardous cargo such as Liquefied Natural Gas (LNG) or Liquefied Petroleum Gas (LPG) by road tanker truck or rail tank car carries significant risk.

In the event of a collision, roadside incident, or weather-related emergency, materials like ethane, methane, butane, and propane can ignite or explode. These incidents may result in serious injury, property damage, or contamination of the surrounding environment due to leaks or spills.

Transportation – Pneumatics Insurance provides essential liability protection for dry bulk carriers and specialized haulers of flammable gases like butane and propane. This coverage helps manage the unique risks associated with transporting volatile or pressurized materials.

What is Transportation – Pneumatics Insurance?

Transportation – Pneumatics Insurance is a specialized type of commercial insurance designed for companies that haul dry bulk goods or compressed gases. These materials are often transported using pneumatic tankers or pressurized containers, making the risk profile significantly different from standard freight transport. The policy typically helps cover liability and potential losses related to accidents, spills, and environmental damage.
