Actually, the statements that you have to handle and store it in a responsible manner, or face strict liability and the statement that the owner is responsible when somebody blows themselves up are largely the same.

The reason for careful handling and storage is to prevent injury, and thus to prevent liability. If injury occurs, the owner is screwed, no matter how many labels there are.

So the prudent owner is very careful about how he handles and stores his dynamite.

Unfortunately, it is not possible to be a prudent manufacturer or distributer of cigarettes, since the very nature of the product is to have somebody stick it between his lips, light it, and suck on the smoke, which is inherently dangerous, no matter how many warning labels there are.

Now here's your THIRD statement, which is different from your previous "you JUST have to handle and store it in a responsible manner."

If you ever decide what legal principle you wish to support, do let me know. Trying to nail jello to a wall is not my idea of a good time.
