Summary
The Halifax Explosion was a maritime disaster in Halifax, Nova Scotia, Canada, which happened on the morning of 6 December 1917. The Norwegian vessel SS Imo collided with SS Mont-Blanc, a French cargo ship laden with high explosives, in the Narrows, a strait connecting the upper Halifax Harbour to Bedford Basin, causing a large explosion on the French freighter, devastating the Richmond district of Halifax.
Approximately 2,000 people were killed by the blast, debris, fires or collapsed buildings, and an estimated 9,000 others were injured. The blast was the largest man-made explosion at the time, releasing the equivalent energy of roughly 2.9 kilotons of TNT (12,000 GJ).

Summary
The United States flag tanker “Edgar M. Queeny” rammed the Greek tanker “Corinthos,” while the latter was discharging 400,000 bbl of crude oil at a refinery jetty at Marcus Hook on the Delaware River. A huge initial explosion, and subsequent explosions and fires, occurred on the Greek ship as a result.
Twenty-five crew members were killed on board the vessel, in addition to a crewman from the flag tanker. The Corinthos sank shortly afterwards and was later removed for scrapping.

Summary
Some 25 miles of Trans-Andean pipeline disappeared in this event, which also damaged natural gas and gasoline pipelines. All 285 producing wells were shut down and oil exports were suspended and swap arrangement made with Venezuelan suppliers. The first earthquake registered 6.0 on the Richter scale, the second 6.8, and there was a total of 10 earthquakes in total. Repairs took several months.

Summary
On March 11, 2011, the Great East Japan Earthquake triggered an extremely severe nuclear accident at the Fukushima Daiichi Nuclear Power Plant, owned and operated by the Tokyo Electric Power Company (TEPCO). This devastating accident was ultimately declared a Level 7 (“Severe Accident”) by the International Nuclear Event Scale (INES).
When the earthquake occurred, Unit 1 of the Fukushima Daiichi plant was in normal operation at the rated electricity output according to its specifications; Units 2 and 3 were in operation within the rated heat parameters of their specifications; and Units 4 to 6 were undergoing periodical inspections. The emergency shut-down feature, or SCRAM, went into operation at Units 1, 2 and 3 immediately after the commencement of the seismic activity.
Although there were no immediate fatalities, a worker later died from radiation exposure (https://www.reuters.com/article/us-japan-fukushima-radiation/japan-acknowledges-first-radiation-death-among-fukushima-workers-idUSKCN1LL0OA)

Summary
A major explosion occurred at a 145,000-barrels-per-day refinery in the north-eastern city of Sendai, hours after the largest earthquake in the country’s history was followed by a tsunami. The fire at the Sendai refinery originated from a land oil product shipping facility. Workers at the refinery were evacuated, and there was no capacity available to extinguish the fire. Fire in the storage and shipping facilities had also damaged a 35,500 barrels-per-day FCC at the refinery.

Summary
The Alexander L Kielland was a semi-submersible platform accommodating the workers of the bridge-linked Edda oil rig in the Ekofisk field, approximately 235 miles east of Dundee, Scotland, in the Norwegian Continental Shelf. The Phillips Petroleum-operated platform capsized in March 1980, killing 123 people.
Only 89 out of 212 workers survived the accident and most died by drowning as the platform turned upside-down in deep waters. The platform capsized after the failure of one of the bracings attached to one leg of the five-legged platform structure after strong winds created waves of up to 12 m high on the day of the accident.

Summary
On April 9, 1998, an 18,000-gallon propane tank exploded at the Herrig Brothers farm in Albert City, Iowa. The explosion killed two volunteer firefighters and injured seven other emergency response personnel. Several buildings were also damaged by the blast.
KEY ISSUES:
• DESIGN & INSTALLATION DEFICIENCIES
• REGULATORY OVERSIGHT
• BLEVE HAZARD & EMERGENCY RESPONSE
ROOT CAUSES:
1. Protection for aboveground piping was inadequate.
2. The diameter of the pipe downstream from an excess flow valve was too narrow, which prevented the valve from functioning properly.
3. Fire fighter training for responding to BLEVEs was inadequate.
