An accident, also known as an unintentional act, is an undesirable, incidental, and an unplanned event that could have been prevented had circumstances leading up to the accident been recognized, and acted upon, prior to its occurrence. Most scientists who study unintentional injury avoid using the term "accident" and focus on factors that increase risk of severe injury and that reduce injury incidence and severity.

Physical and non-physical
Physical examples of accidents include unintended motor vehicle collisions or falls, being injured by touching something sharp, hot, dropping a plate, accidentally kicking the leg of a chair while walking, unintentionally biting one's tongue while eating, accidentally tipping over a glass of water, contacting electricity or ingesting poison. Non-physical examples are unintentionally revealing a secret or otherwise saying something incorrectly, accidental deletion of data, forgetting an appointment etc.
Accidents By activity
Accidents during the execution of work or arising out of it are called work accidents. According to the International Labour Organization (ILO), more than 337 million accidents happen on the job each year, resulting, together with occupational diseases, in more than 2.3 million deaths annually.
Incidence of accidents (of a severity of resulting in seeking medical care), sorted by activity (in Denmark in 2002).
Poisons, vehicle collisions and falls are the most common causes of fatal injuries. According to a 2005 survey of injuries sustained at home, which used data from the National Vital Statistics System of the United States National Center for Health Statistics, falls, poisoning, and fire/burn injuries are the most common causes of death.
