Any article that is inherently hazardous or has the potential for harming people through its careless use.
Examples of a dangerous instrumentality include explosives and electrically charged wires. Statutes and case law must be consulted to determine what items are regarded as dangerous instrumentalities.
When dealing with dangerous instrumentalities, some jurisdictions require that due care be exercised to prevent harm to those who are reasonably expected to be in proximity with them. Others impose STRICT LIABILITY for injuries and losses caused by them.
