Why can propane or butane be more dangerous than gasoline on a boat?

  1. They are lighter than air

  2. Highly explosive and heavier than air

  3. Cause corrosion

  4. Only dangerous in high temperatures

The correct answer is: Highly explosive and heavier than air

Propane and butane are considered more dangerous than gasoline on a boat because they are highly explosive and heavier than air. This means that any potential gas leaks or spills can easily accumulate in the lower levels of the boat and can quickly ignite with any source of ignition, causing a potentially catastrophic explosion. The fact that they are heavier than air also means that they can disperse and linger in the boat's confined spaces, increasing the risk of explosion. On the other hand, gasoline is typically lighter than air and will dissipate more quickly in the event of a leak or spill. While gasoline can still be dangerous in certain situations, it is generally considered less explosive and dangerous on board a boat compared to propane or butane. Additionally, gasoline fumes do not typically cause corrosion, unlike propane and butane which can damage metal surfaces. And contrary to option D, propane and butane can still be
