Under Nevada law, one who carries on an abnormally dangerous activity is liable for harm to another person or property that results from the activity, even if he has exercised the utmost care to prevent the harm. It is not enough, however, that a dangerous substance is involved. The question is whether the defendant's activity as a whole is ultra-hazardous. Otherwise, many defendants that produce or rely on dangerous substances would never be able to engage in a commercial or industrial activity. Courts have recognized six factors to be taken into account when determining whether an activity is abnormally dangerous: 1) The existence of a high risk of harm to people or property; 2)The likelihood that such harm will be great; 3) The inability to eliminate the risk by the exercise of reasonable care; 4) The extent to which the activity is not a matter of common usage; 5) The inappropriateness of the activity to the place where it is carried on; and 6) The extent to which the activity's value to the community is outweighed by its dangerous attributes. Based on these factors, if a court determines that the defendant was engaged in an abnormally dangerous activity, the defendant will be strictly liable for harm resulting from the activity.
