Latent human error

Latent human error is a common reason for an accident that causes damage. The errors effect does not happen immediately and is often a result of multiple errors made by people in a system that is set up poorly. Thus, latent human error causes indirect and not immediately obvious damage. Latent human error is often discussed in aviation mistakes, and makes up over 70% of the accidents. By gathering data about errors made, then collating, grouping and analyzing them, it can be determined whether a disproportionate amount of similar errors are being made. If this is the case, a contributing f ...

List of mass evacuations

This list of mass evacuations includes emergency evacuations of a large number of people in a short period of time. An emergency evacuation is the movement of persons from a dangerous place due to the threat or occurrence of a disastrous event whether from natural or man made causes, or as the result of war.

Jessica McClure

Jessica McClure Morales fell into a well in her aunts backyard in Midland, Texas on October 14, 1987, at the age of 18 months. Between that day and October 16, rescuers worked for 56 hours to free her from the 8-inch well casing 22 feet below the ground. The story gained worldwide attention, and later became the subject of a 1989 ABC television movie Everybodys Baby: The Rescue of Jessica McClure.

Normal Accidents

Normal Accidents: Living with High-Risk Technologies is a 1984 book by Yale sociologist Charles Perrow, which provides a detailed analysis of complex systems from a sociological perspective. It was the first to "propose a framework for characterizing complex technological systems such as air traffic, marine traffic, chemical plants, dams, and especially nuclear power plants according to their riskiness". Perrow argues that multiple and unexpected failures are built into societys complex and tightly coupled systems. Such accidents are unavoidable and cannot be designed around. Perrows argum ...

Personal watercraft-related accidents

The number of personal watercraft-related accidents has increased with the popularity of personal watercraft since their introduction during the late 1960s. The use of the term "jet ski" for all types of PWCs is a misnomer; Jet Ski is a registered trademark in the United States for a line of PWCs manufactured by Kawasaki). With the increased use of personal watercraft since their inception, the hazards accompanying their use have also increased. According to U.S. government reports, most accidents are associated with rental operators, underage operators, under-trained and undereducated boa ...

List of selfie-related injuries and deaths

This is a list of serious injuries and deaths in which one or more subjects of a selfie were killed or injured, either before, during or after having taken a photo of themselves, with the accident at least in part attributed to the taking of the photo. The United States Department of Transportation estimated that during 2014, the so-called "year of the selfie", 33.000 people were injured while driving and using a cell-phone in some fashion, which can include talking, listening, and "manual button/control actuation" including taking, uploading, downloading, editing, or opening of selfies. A ...

Solomon curve

The Solomon curve is a graphical representation of the collision rate of automobiles as a function of their speed compared to the average vehicle speed on the same road. The curve was based on research conducted by David Solomon in the late 1950s and published in 1964. Subsequent research suggests significant biases in the Solomon study, which may cast doubt on its findings.

Unintentional discharge

Unintentional discharge is the event of a firearm discharging at a time not intended by the user. An unintended discharge may be produced by an incompatibility between firearm design and usage, such as the phenomenon of cooking off a round in a closed bolt machine gun, a mechanical malfunction as in the case of slamfire in an automatic weapon, user induced due to training issues or negligence, or a simple accident. The phenomenon has also been defined in the scientific literature as an activation of the trigger mechanism that results in an unplanned discharge that is outside of the firearm ...

Use error

The term use error has recently been introduced to replace the commonly used terms human error and user error. The new term, which has already been adopted by international standards organizations for medical devices, suggests that accidents should be attributed to the circumstances, rather than to the human beings who happened to be there.

When Technology Fails

When Technology Fails, edited by Neil Schlager, is a collection of 103 case studies about significant technological disasters, accidents, and failures of the 20th century. It was published in 1994 by Gale Research, Inc. It was one of the top referenced books in the New York Public Library in 1995. The book was updated and re-released in 2005. The book consists of 1.000- to 1.500-word entries, arranged by subject, that discuss the background, timeline, and impact of each event. Each entry is written by journalists, engineers, and researchers, and provides a cursory overview, rather than in- ...

Kickback (chainsaw)

This article is about risk control methods specific to chainsaws and chainsaw operations. Chainsaws incorporate numerous safety features common to many engine-driven power tools. Manufacturers have invented numerous design features to improve safety. Some features have become de facto standards, and others are legal requirements in particular jurisdictions. Best practice dictates that an operator should inspect the saw before starting work and only operate the saw if all the safety features are properly functional. Additional safety features are a significant commercial advantage to chains ...
