Finnart Oil Terminal, also known as Finnart Ocean Terminal or Chap Point, is an oil depot on the eastern shore of Loch Long, Firth of Clyde on the west coast of Scotland, about 2 mi to the north of Garelochhead on the A814 road to Arrochar.
 It has piers extending a short distance into the loch, providing a deep water berth for oil tankers up to 324,000 tonnes.
 Two pipelines connect the terminal across the width of Scotland to the Grangemouth Refinery on the Firth of Forth on the east coast, and extensive oil storage tanks have been built into the hillside on both sides of the main road.
Buncefield oil depot is operated by Hertfordshire Oil Storage Ltd (HOSL) and officially known as the Hertfordshire Oil Storage Terminal.
 It is an oil depot located on the edge of Hemel Hempstead to the north of London in the United Kingdom (UK).
 In December 2005 there was a series of explosions on the site which caused the largest fire in Europe since World War II.
Disaster Masters was a series on BBC1 which followed the workers of the British emergency and non-emergency repairs company Homeserve as they carried out repair work contracted by householders' insurance companies.
 During the different series, they were seen dealing with major disasters such as the Carlisle floods, Birmingham tornado and the Buncefield oil depot explosion.
 They were also seen carrying out more minor repairs such as boarding up broken windows.
The San Juanico disaster was an industrial disaster caused by a massive series of explosions at a liquid petroleum gas (LPG) tank farm in San Juanico, Mexico (outside of Mexico City, Mexico) on 19 November 1984.
 The explosions consumed 11,000 m of LPG, representing one third of Mexico City's entire liquid petroleum gas supply.
 The explosions destroyed the facility and devastated the local town of San Juan Ixhuatepec, with 500–600 people killed, and 5000–7000 others suffering severe burns.
 The San Juanico disaster was one of the deadliest industrial disasters in world history.
Kingsbury Oil Terminal is an oil storage depot located to the northeast of the village of Kingsbury, Warwickshire, England.
 It was opened in the late 1960s and serves the Midlands region.
 It is the largest inland oil storage depot in the United Kingdom.
 The main operators at the site are BP, Warwickshire Oil Storage Limited and Valero Energy Corporation.
 The site also has facilities from Shell and pipeline operations from the British Pipeline Agency.
On 12 August 2015, a series of explosions killed 173 people and injured hundreds of others at a container storage station at the Port of Tianjin.
 The first two explosions occurred within 30 seconds of each other at the facility, which is located in the Binhai New Area of Tianjin, China.
 The second explosion was far larger and involved the detonation of about 800 tonnes of ammonium nitrate.
 Fires caused by the initial explosions continued to burn uncontrolled throughout the weekend, repeatedly causing secondary explosions, with eight additional explosions occurring on 15 August.
The Fateh Oil Field, also called the Fath Oil Field, is an area of offshore oil production approximately 60 mi from Dubai and within that country's share of the Persian Gulf.
 It was discovered in 1966, and was named Fateh (meaning "Conqueror") by Dubai monarch Rashid bin Saeed Al Maktoum.
 In 1968, Continental Oil Company announced plans to construct a 500000 oilbbl underwater oil storage facility to hold petroleum extracted from the field.
 The underwater storage was a world first, as before that time, offshore oil production had been channeled to onshore storage and tanker loading facilities.
 The first of these underwater holding tanks, called Khazzans, was completed in 1969, the date the first barrel of oil was shipped from the field to world markets on September 22, 1969.
The Buncefield fire was a major conflagration caused by a series of explosions on 11 December 2005 at the Hertfordshire Oil Storage Terminal, an oil storage facility located near the M1 motorway by Hemel Hempstead in Hertfordshire, England.
 The terminal was the fifth largest oil-products storage depot in the United Kingdom, with a capacity of about 60 e6impgal of fuel.
 The terminal is owned by TOTAL UK Limited (60%) and Texaco (40%).
The PEPCON disaster was an industrial disaster that occurred in Henderson, Nevada on May 4, 1988 at the Pacific Engineering and Production Company of Nevada (PEPCON) plant.
 The conflagration and subsequent explosions killed two people, injured 372 others, and caused an estimated US$100 million of damage.
 A large portion of the Las Vegas Valley within a 10 mi radius of the plant was affected, and several agencies activated disaster plans.
An Industrial fire is a type of industrial disaster involving a conflagration which occurs in an industrial setting.
 Industrial fires often, but not always, occur together with explosions.
 They are most likely to occur in facilities where there is a lot of flammable material present.
 Such material can include petroleum, petroleum products such as petrochemicals, or natural gas.
 Processing flammable materials such as hydrocarbons in units at high temperature and/or high pressure makes the hazards more severe.
 Facilities with such combustible material include oil refineries, tank farms (oil depots), natural gas processing plants, and chemical plants, particularly petrochemical plants.
 Such facilities often have their own fire departments for firefighting.
 Sometimes large amounts of dust or powder are vulnerable to combustion and their ignition can cause dust explosions. Severe industrial fires have involved multiple injuries, loss of life, costly financial loss, and/or damage to the surrounding community or environment.
