What is the consequence of not properly securing cylinders in transit?

Properly securing cylinders during transit is crucial for several reasons, primarily to minimize the risk of movement, tipping over, and physical damage. When cylinders are not secured, they can shift, roll, or fall during transport due to sudden stops, turns, or other road conditions. This movement can lead to dangerous situations where cylinders could cause accidents by damaging other vehicles or injuring individuals.

Moreover, unsecured cylinders may also become damaged themselves, leading to leaks or compromised integrity of the cylinder. This could not only cause financial losses due to the need for replacements but also pose significant safety risks, including the potential for fire or explosion, especially with liquefied petroleum gas (LPG) which is flammable.

Therefore, option B emphasizes the critical safety implications and risks associated with improper securing of cylinders, making it the correct answer in the context of transporting liquefied petroleum gas.
