Abnormally dangerous activities are those that carry inherent risks of significant harm to persons or property even when reasonable care is exercised.

The doctrine of abnormally dangerous activities applies strict liability to defendants engaged in certain inherently hazardous activities, meaning that they can be held liable for harm that results from such activities regardless of the precautions taken. The essence of this doctrine lies in the recognition that some activities carry risks that are so great that they cannot be conducted without exposing others to potential harm, even if all due care is exercised by the operator. Such activities may include the use of explosives, radioactive materials, or keeping wild animals as pets.
The abnormally dangerous activities test emerged from the landmark case of Rylands v. Fletcher (1868), where the court reasoned that a person who brings something onto their land that is likely to cause harm if it escapes may be held strictly liable for any resulting damage. This concept has since been embraced in modern tort law in the U.S., particularly under Restatement (Second) of Torts § 520, which outlines specific factors courts should consider when determining whether an activity is abnormally dangerous.
Critically, the Restatement lists several factors to consider in establishing whether an activity qualifies as abnormally dangerous, including: the existence of a high degree of risk, the likelihood that the harm will be great if caused, and whether the activity is uncommon in the area where it takes place. Courts also examine the value of the activity to the community versus its risk to individual safety, balancing societal benefits against potential dangers.
Due to the nature of strict liability, plaintiffs are relieved from proving negligence; they simply need to show that a legally recognized abnormally dangerous activity caused their damages. However, defenses such as assumption of risk can still apply, mitigating liability. In sum, this area of law plays a critical role in ensuring that those who engage in particularly hazardous activities bear the costs of harm incurred by others, thus compelling stricter safety practices and accountability.
The concept of abnormally dangerous activities has its roots in the 19th century, specifically from the English case Rylands v. Fletcher (1868) which established the principle of strict liability for certain hazardous activities.
Established the foundation for strict liability in the context of abnormally dangerous activities.
Reinforced the factors to determine whether an activity should be classified as abnormally dangerous.
Affirmed strict liability for damages arising from chemical exposure, illustrating the range of abnormally dangerous activities.
Clarified the expectations regarding the defense of assumption of risk in strict liability cases.
A construction company uses dynamite to break rocks for a new building site. Despite taking all necessary precautions, the dynamite explosion causes debris to fly and injure a nearby resident. The construction company may be held strictly liable for the injuries sustained due to the inherently dangerous nature of the activity.
Confusion: All hazardous activities are considered abnormally dangerous.
Clarification: Only those activities that meet specific criteria defined by law, such as the likelihood and severity of possible harm, are classified as abnormally dangerous.
Confusion: Negligence must be proven in cases involving abnormally dangerous activities.
Clarification: In strict liability cases for abnormally dangerous activities, negligence is not required; the mere occurrence of harm is sufficient.
Focus on clearly distinguishing between abnormally dangerous activities and general negligence claims to demonstrate understanding of strict liability principles.
