Answer: an abnormally dangerous activity
Explanation: Strict liability theory is a theory that imposes legal responsibility for damages or injuries even if the person who was found strictly liable did not act with fault or negligence. The individual bringing the claim need only prove that the tort occurred and that the defendant was responsible.
The law imposes strict liability to situations it considers to be inherently dangerous, such as the situation whereby West Agricultural Services, Inc. stores such quantity of ammonium nitrate, which by the way is highly explosive, on its property.
It does not matter that they took all precautions and didn't mean for an explosion to occur, the company is liable if injuries occur as a result of an explosion.
