Merrimack Valley Gas Explosions
On September 13, 2018, excessive pressure in natural gas lines owned by Columbia Gas of Massachusetts caused a series of explosions and fires to occur in as many as 40 homes, with over 80 individual fires, in the towns of Lawrence, Andover, and North Andover, all within the Merrimack Valley, in Massachusetts, United States. One person, Leonel Rondon, was killed and 30,000 were forced to evacuate their homes immediately. Background According to the NTSB's preliminary report, customers in the accident area received gas from a low-pressure (0.5 psi) distribution network which, in turn, was fed from a high-pressure (75 psi) main pipeline via regulators controlled by sensors measuring pressure in the low-pressure pipes. At the time of the accident, workers were replacing some of the low-pressure piping, but the procedure set out by Columbia Gas for doing this failed to include transfer of a regulator's pressure sensor from the old, disused piping to the new. As a result, when the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Daylight Time
The Eastern Time Zone (ET) is a time zone encompassing part or all of 23 states in the eastern part of the United States, parts of eastern Canada, the state of Quintana Roo in Mexico, Panama, Colombia, mainland Ecuador, Peru, and a small portion of westernmost Brazil in South America, along with certain Caribbean and Atlantic islands. Places that use: * Eastern Standard Time (EST), when observing standard time (autumn/winter), are five hours behind Coordinated Universal Time ( UTC−05:00). * Eastern Daylight Time (EDT), when observing daylight saving time (spring/summer), are four hours behind Coordinated Universal Time ( UTC−04:00). On the second Sunday in March, at 2:00 a.m. EST, clocks are advanced to 3:00 a.m. EDT leaving a one-hour "gap". On the first Sunday in November, at 2:00 a.m. EDT, clocks are moved back to 1:00 a.m. EST, thus "duplicating" one hour. Southern parts of the zone (Panama and the Caribbean) do not observe daylight saving time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Merrimack River
The Merrimack River (or Merrimac River, an occasional earlier spelling) is a river in the northeastern United States. It rises at the confluence of the Pemigewasset and Winnipesaukee rivers in Franklin, New Hampshire, flows southward into Massachusetts, and then flows northeast until it empties into the Gulf of Maine at Newburyport. From Pawtucket Falls in Lowell, Massachusetts, onward, the Massachusetts–New Hampshire border is roughly calculated as the line three miles north of the river. The Merrimack is an important regional focus in both New Hampshire and Massachusetts. The central-southern part of New Hampshire and most of northeast Massachusetts is known as the Merrimack Valley. Several U.S. naval ships have been named and USS ''Merrimac'' in honor of this river. The river is perhaps best known for the early American literary classic ''A Week on the Concord and Merrimack Rivers'' by Henry David Thoreau.

State Of Emergency
A state of emergency is a situation in which a government is empowered to be able to put through policies that it would normally not be permitted to do, for the safety and protection of its citizens. A government can declare such a state during a natural disaster, civil unrest, armed conflict, medical pandemic or epidemic or other biosecurity risk. ''Justitium'' is its equivalent in Roman law—a concept in which the Roman Senate could put forward a final decree (''senatus consultum ultimum'') that was not subject to dispute yet helped save lives in times of strife. Relationship with international law Under international law, rights and freedoms may be suspended during a state of emergency, depending on the severity of the emergency and a government's policies. Use and viewpoints Though fairly uncommon in democracies, dictatorship, dictatorial regimes often declare a state of emergency that is prolonged indefinitely for the life of the regime, or for extended periods of t ...

Asset Integrity Management Systems
Asset Integrity Management Systems (AIMS) outline the ability of an asset to perform its required function effectively and efficiently whilst protecting health, safety and the environment and the means of ensuring that the people, systems, processes, and resources that deliver integrity are in place, in use and will perform when required over the whole life-cycle of the asset. The technical aspects of AIMS are illustrated in Figure 1. Originally developed in the UK, Asset Integrity Management was the result of a collaboration between the HSE and leading oil and gas operators resulting in a series of reports (Belfry Report) and workshops, the outcome being a group of documents called Key Programmes (KP Series), currently publicly available. An Integrity Management System should address the quality at every stage of the asset life cycle, from the design of new facilities to maintenance management to decommissioning. Inspections, auditing/assurance and overall quality processes are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
