If you have been reading about laboratory-safety and want a single page that covers the useful parts, this is it: definitions, context, how it is studied, and the questions that come up repeatedly.
Last reviewed on 2025-05-08. Where a claim depends on a specific study, the study is described rather than over-claimed.
The Aviation Safety Reporting System (ASRS) collects voluntarily submitted aviation safety incident/situation reports from pilots, controllers and others. The ASRS uses reports to identify system deficiencies, issue alert messages, and produce two publications, CALLBACK, and ASRS Directline. The collected information is made available to the public, and is used by the FAA, NASA and other organizations working in research and flight safety.
1-Heneicosanol is the C21 member of the series of linear, saturated primary alcohols derived formally from heneicosane by substitution of a terminal hydrogen atom with a hydroxyl group. It is classified as a long-chain fatty alcohol. Commercial material is typically obtained as a white powder or low-melting wax with a reported melting range of about 68–71 °C. A safety data compilation and estimation methods indicate a high normal boiling point of around 366 °C at 760 mmHg, consistent with its long carbon chain. The compound has very low solubility in water and a high octanol/water partition coefficient (log P), reflecting its pronounced hydrophobic character.
On 1 December 1978, the Health and Safety Executive announced their intention to prosecute the university for breach of safety legislation. The case was heard in October 1979 at Birmingham Magistrates' Court. Although the source of infection was traced, the mode and cause of transmission was not. Evidence presented by several internationally recognised experts, including Kevin McCarthy, Allan Watt Downie and Keith R. Dumbell, showed that airborne transmission from the laboratory to the telephone room where Parker was supposedly infected was highly improbable. The experts calculated that it would require 53,700 litres (11,812 imp gal) of virus fluid to have been aspirated (meaning, in this context, removed by suction of fluid and cells through a needle) and it would take 20,000 years for one particle to travel to the telephone room at the rate the fluid was aspirated. It was additionally found that although the Shooter Inquiry noted the poor state of the duct sealing in the laboratory, this was caused after the outbreak by engineers fumigating the laboratory and ducts. The university was found not guilty of causing Parker's death.
The Japan Transport Safety Board investigates aviation accidents and incidents. The Aircraft Accident Investigation Commission investigated aviation accidents and incidents in Japan until October 1, 2001, when the Aircraft and Railway Accidents Investigation Commission (ARAIC) replaced it, and the ARAIC did this function until October 1, 2008, when it merged into the JTSB. Established in 2016, the Air Accident Investigation Bureau (AAIB) Malaysia is the main investigation body for aircraft accident/incident. Separate from Civil Aviation Authority of Malaysia (CAAM) and Malaysian Aviation Commission (MAVCOM) that is the national aviation authority and commission that oversee aviation economy respectively. The AAIB operates from the ministry of transport headquarters in Putrajaya, and its black box laboratory situated in STRIDE, the ministry of defenses research institute. AAIB Malaysia is teamed by civilians and seconded Royal Malaysian Airforce senior officer and a group of pool investigators from Malaysia Institute of Aviation Technology

The terms "active" and "passive" are simple but important terms in the world of automotive safety. "Active safety" is used to refer to technology assisting in the prevention of a crash and "passive safety" to components of the vehicle (primarily airbags, seatbelts and the physical structure of the vehicle) that help to protect occupants during a crash. Crash avoidance systems and devices help the driver — and, increasingly, help the vehicle itself — to avoid a collision. This category includes: The vehicle's headlamps, reflectors, and other lights and signals The vehicle's mirrors The vehicle's brakes, steering, and suspension systems A subset of crash avoidance is driver assistance systems, which help the driver to detect obstacles and to control the vehicle. Driver assistance systems include:
Weapon No. 2, which underwent something other than normal release from the aircraft, evidenced by the fact that the parachute did not deploy, also had its arming rods extracted, and those components which were given the opportunity to act, did act in the manner expected. Full operation of this weapon was prevented by several things: Impact occurred so soon after separation of the Bisch rods that the timers were not given an opportunity to run down. The Arm/Safe Switch was in the "Safe" condition as the weapon left the aircraft. Another analysis by Sandia engineers in 1961 concluded that while in both weapons the MC-772 Arm/Safe Switch operated "as it was designed to do," the lanyard-controlled safing-pins "cannot be relied upon to prevent initiation of the fuzing sequence" in this kind of accident, and recommended implementing a modification to the weapons "as rapidly as possible" that would prevent the fuze power supply from activating except when live release was intended. A 1969 analysis by Sandia supervisor Parker F. Jones concluded that the Goldsboro accident illustrated that "the Mk 39 Mod 2 bomb did not possess adequate safety for the airborne alert role in the B-52."
From 1935–1972, the authorising body governing radiation in Australia was the Commonwealth X-Ray and Radium Laboratory. This was replaced by the Commonwealth Radiation Laboratory (1972–1973), and then the Australian Radiation Laboratory (1973–1999). In 1999, the Australian Radiation Laboratory then merged with the Nuclear Safety Bureau to create one agency that governed radiation and nuclear safety, ARPANSA. Since its establishment, ARPANSA has offices in both Sydney, NSW, and Melbourne, Victoria.
Environmental health laboratories are governmental laboratories that conduct testing to protect human health and the environment. In some states, a single laboratory acts as both the environmental and the public health laboratory. In other states, the environmental laboratory is part of the department of environmental quality or natural resources while the public health laboratory is part of the health department. Environmental health laboratories help to identify contaminants by conducting regular testing of water, air, soil, food and other media to ensure that populations are not being exposed to unhealthy levels of contamination. APHL supports these laboratories by coordinating a response to environmental health issues. They assist in providing information and training to the scientists working in the labs, and serve as a link between member laboratories and federal agencies, including Centers for Disease Control and Prevention's (CDC) National Center for Environmental Health and the US Environmental Protection Agency.

The Association of Public Health Laboratories (APHL) is a membership organization in the United States representing the laboratories that protect the health and safety of the public. APHL serves as a liaison between public health laboratories and federal and international agencies. Membership consists of local, state, county, and territorial public health laboratories; public health environmental, agricultural and veterinary laboratories; and corporations and individuals with an interest in public health and laboratory science. APHL is a non-profit, 501(c)(3) organization with a history of over fifty years.
Annex 13 of the Chicago Convention provides the international Standards And Recommended Practices that form the basis for air accident and incident investigations by signatory countries, as well as reporting and preventive measures. The International Civil Aviation Organization (ICAO) is specifically focused on preventing accidents, rather than determining liability. In Australia, the Australian Transport Safety Bureau is the federal government body responsible for investigating transport-related accidents and incidents, covering air, sea, and rail travel. Formerly an agency of the Department of Infrastructure, Transport, Regional Development and Local Government, in 2010, in the interests of keeping its independence it became a stand-alone agency.
On 1 March, the Department of Food and Veterinary of Lithuania announced that horse meat was found in three canned beef brands sold by Latvian company Kuršu Zeme. Canned beef made by the Latvian company was removed from sale in Lithuania. === Wiljo Import en Export B.V. and Vleesgroothandel Willy Selten B.V. === On 10 April 2013, it was reported that two Dutch trading companies, owned by the same person whom food safety officials had previously investigated, may have supplied 50,000 metric tonnes of adulterated beef containing horse meat since January 2011. On 7 February 2013, it was revealed by the Food Standards Agency that the Findus beef lasagne range in the UK, France, Norway, and Sweden, and the shepherd's pie and moussaka ranges in France, contained horse meat without proper declaration or official scrutiny. The contamination may have gone on since summer 2012 according to a leaked document.
Observant Muslims and Jews consider it sinful to eat certain types of meat, pork for both groups, and also horse and many other animals for Jews, due to religious prohibitions. Professor Reilly stated "for some religious groups or people who abstain from eating pig meat, the presence of traces of pig DNA is unacceptable". On 15 March 2013, a Westminster health and safety survey confirmed that pig DNA had been found in halal chicken sausages produced for schools.
When measured by fatalities per person transported, however, buses are the safest form of transportation. The number of air travel fatalities per person are surpassed only by bicycles and motorcycles. This statistic is used by the insurance industry when calculating insurance rates for air travel. For every billion kilometers traveled, trains have a fatality rate that is 12 times higher than that of air travel, and the fatality rate for automobiles is 62 times greater than for air travel. By contrast, for every billion journeys taken, buses are the safest form of transportation; using this measure, air travel is three times more dangerous than car transportation, and almost 30 times more dangerous than travelling by bus. A 2007 study by Popular Mechanics magazine found that passengers sitting at the back of an aeroplane are 40% more likely to survive a crash than those sitting at the front. The article quotes Boeing, the FAA, and a website on aircraft safety, all of which claim that there is no "safest" seat. The study examined 20 crashes, not taking into account the developments in safety after those accidents. However, a flight data recorder is usually mounted in the aircraft's empennage (tail section) where it is more likely to survive a severe crash. Between 1983 and 2000, the survival rate for people in U.S. plane crashes was greater than 95 percent.
