What is the role of chock blocks in relation to cargo tank vehicles?

Chock blocks are essential safety devices used in conjunction with cargo tank vehicles to prevent them from moving when they are loaded or parked. Their primary function is to provide a secure and stable interface between the vehicle and the ground, ensuring that the tank remains stationary and reducing the risk of accidents such as rollaways or unintended movements.

When a cargo tank vehicle is loaded with liquefied petroleum gas or other materials, it is vital for safety that the vehicle does not move unexpectedly, which could cause spills, leaks, or even catastrophic failures. By securely blocking the wheels of the vehicle, chock blocks provide a mechanical barrier that helps maintain stability. This is especially important on inclines or uneven surfaces where gravitational forces could cause the vehicle to roll.

While chock blocks may enhance the safety and operational efficiency of cleaning operations, assist in stabilizing during maintenance, or serve aesthetic purposes in specific contexts, their fundamental role is rooted in ensuring the vehicle remains securely in place when parked or loaded.
