Emergency restoring operations

Primary medical treatment facilities may be damaged or inoperable thus, assessment and emergency restoration to necessary operational levels is a basic requirement to stabilize the medical support system. 

The fourth priority is restoring operations and getting things back to normal. Companies or businesses will lose income and production until operations resume. Following an emergency someone must check the condition and safety of equipment. Some items will require repair. Startup procedures may require specialized leadership and skill. Case 29-1 and Case 29-2 illustrate the importance of managing restoration of operations. 

Guidelines are also established for hot functional tests to be performed by the owner-operator in accordance with BTP ASB 10-2. These tests are to verify that unacceptable feedwater system water hammer does not occur when (a) using normal plant operating procedures for normal and emergency restoration of SG water level following loss of main feedwater, and (b) transferring main feedwater during normal operation from the SG downcomer feedwater inlet nozzles to the economizer inlet nozzles. (See CESSAR-DC, Sections 14.2.12.1.63 and 14.2.12.4.13, respectively.)... 

Rice and Caniato (2003) discussed the emerging expectations with respect to supply chain security when they described the need for creating both secure supply chains (e.g., supply chains that maintain advanced security processes/procedures) and resilient supply chains (e.g., supply chains that are able to react quickly and restore operations when unexpected sruptions occur). Given the widespread nature of the food supply chain, creating both a secure supply chain as well as a resilient supply chain is of utmost importance. 

Protecting facilities, equipment, and vital records is essential to restoring operations once an emergency has occurred.

The Lead Operator must take immediate action to restore the out-of-service instrument. On a normal day shift, this will require contact with the supervisor who may direct the efforts of a mechanic, or generate an Emergency work order. On the back shifts or holidays, this may mean having the Shift Supervisor summon the mechanic(s) from home. 

The intervention of well-trained process operators is a vital layer in process safety, as it is usually the last opportunity to restore the process to a safe condition before an emergency shutdown or incident occurs (see Figure 9.1). 

Should an emergency occur requiring immediate shutdown and over-ride of normal sequenhal shutdown, an EMERGENCY STOP pushbutton is provided for this purpose. This device interrupts power to all components in the oxidation unit control circuit, shuts down all motors, and closes the vacuum line valve and the chlorine pressure-reducing valve (PRV). The EMERGENCY STOP pushbutton is also used as a reset device to restore the system to normal operating status after an alarm situation has occurred. 

The electricity supply of a hospital fails. It is restored 2 h later. What is the probability, Ps, for an operation to be carried out, if this requires electricity which has to be supplied by the emergency power generator ... 

The objective of the event-independent part of the Emergency Operating Procedures (EOPs) is to provide means to evaluate and restore the plant nuclear safety. The concept is based on the premise that radiation release to the environment can be minimised if the barriers to activity release are protected (barriers of defence in depth). In order to accomplish this goal, a set of functions has been defined which are critical from the plant nuclear safety point of view. These are the Critical Safety Functions. To be able to evaluate the status of these functions. Status Trees have been designed, one per CSF. Once the state of the CSF is evaluated, based on their state and the rules of priority one can designate a Function Restoration Guideline to be implemented for restoring CSF (see Appendix 3). 

The British Standard recommends that the full load should be carried by the emergency supply for at least one hour in every six months. After testing, the emergency system must be carefully restored to its normal operative state. A record should be kept of each item of equipment and the date of each test by a qualified or responsible person. It may be necessary to produce the record as evidence of satisfactory compliance with statutory legislation to a duly authorized person. 

High-pressure steam may also serve as a driver for turbines. Chlor-alkali plants, which are usually placed in areas of low electrical power cost, are less likely than most other types to justify the use of steam-turbine drives but still may use them as a backup source of power. Furthermore, one of the ways to cope with a major electrical failure is to use steam to operate critical drives imtil all systems are shut down or electrical power is restored. An example of a critical service is the caustic circulation pump on the emergency vent scrubber. A spare pump is always necessary, and it should have an independent source of power. One way to accomplish this is with a steam-turbine drive. Other services may also be considered critical for personnel safety or process security. The latter is especially true in a membrane-cell plant, where some systems are vital for the protection of the membranes from damage. 

This book is meant to be a guide to the various therapeutic concepts through which it has clearly emerged that cases of progressive isthmic-dysplastic spondylodesis should be operatively treated as early as possible. Only then is it possible to restore the lumbo-sacral hinge and above all the position of the sacrum in an ideal way. 

DOE-STD-1120 provides guidance for preparing a DSA for decommissioning of nuclear facilities, as well as environmental restoration activities that involve work not done within a permanent structure (DOE-STD-1120-2005). Methodologies provided in this standard are compliant with 10 CFR 830, Subpart B—Safety Basis Requirements. The standard is written to make the maximum utilization of the provisions of 29 CFR 1910.120 or 29 CFR 1926.65— Hazardous Waste Operations and Emergency Response (HAZWOPER). Derivation of controls is also necessary for facility decommissioning projects that involve more than "low level residual fixed radioactivity."... 

As a result, human intervention and action remain unavoidable. There is a need for maximum information as soon as possible to decide whether an emergency situation has arisen and what action is required to restore normal operating conditions rapidly.
