Security location considerations

The location of any premises has a considerable influence on the overall standard of security. With new building, and other things being equal, the site with a low level of local crime should be chosen. In most instances, however. 

The employment of full-time security staff either in-house personnel or contracted out to a professional guarding company (preferably one that is a member of the British Security Industry Association (BSIA) Manned Services Inspectorate) can make a significant contribution to overall security. Consideration should be given to the range of duties to be performed by security staff, their location, and how they will interface with other security measures and external agencies. 

General Considerations 1 Location of people relative to the unit 2 Location of critical systems 3 Dominant wind direction 4 Climate and weather extremes earthquake, flooding, windstorms 5 Site topography 6 External hazards or threats (fire/explosion/toxic release from nearby process or facility aircraft subsidence sabotage) 7 Traffic flow patterns and clearances from process vessels and lines 8 Security and reliability of all critical feeds and utilities 9 Command center and alternate command center locations 10 Evacuation routes, emergency exits, safe rally spots... 

Resource management. This covers the computational and network realities that the workflow must deal with. Data reside in databases and on file servers with their individual networking and security considerations. Similarly, the invocation of an application that is needed to complete a workflow may have specific network requirements. To be useful in a typical organizational network environment, the workflow engine has to maintain information about network locations and network users, plus have the ability to utilize these data in the way that is expected by users and administrators. 

After resolving the issue of matrix design, the next step was to determine a desirable anatomical location. Several considerations were used in determining possible implant sites. The first is the size of the implant and the requirement that it be placed in juxtaposition to well-vascularized tissue. A transplant matrix constructed as a porous sheet-like structure could be at most 200 mm thick, based on estimates of nutrient transport limitations (66). The size of a device required to replace about 5% of the mass of an adult liver would then be about 0.5 m2. Surgical trauma must be avoided when implanting the device, because such trauma produces fibrin clots and hematoma formation around the wounded area, which creates a poor environment for cell survival. Also, the implant may behave better if supplied by the portal circulation rather than the systemic, because the portal circulation contains potential hepatotrophic factors. For these reasons, the mesentery—the vascularized membrane which secures the intestines—was selected as the best potential site (Fig. 15). 

In the spring of 1942, Dr. Stevenson supplied a few federal experimental farms and stations with the small quantity of seed he had on hand. The harvest of that year amounted to 2600 pounds (52 bushels) of seed of Brassi-ca napus species. A considerably larger quantity of seed than this was required for planting in 1943 to relieve the serious shortage of rapeseed oil. Dr. Stevenson located and purchased a total of 41,000 pounds from U.S. seed companies. This seed had originally been secured from Argentina and the name Argentine for the Brassica napus was widely used in the early years of production, and still is applied to the varieties of the Brassica napus species. 

Security of data has become an important consideration. With the expanded use of the Internet, unauthorized individuals may gain access to private and confidential information found in safety software and applications. It is illegal to make some personal information available. Examples are human resource information, medical information, and other data that may link to accident and injury or illness cases. One kind of security involves keeping secure data and information on computers that do not link to other applications. Another kind of security involves encryption techniques for secure data and information. When data and applications reside in other locations, the communicafion interfaces must be secure along with the remote computer systems themselves. 

Small unit volumes of effluent (up to 50 litres) can be treated in a steam autoclave, provided that adequate measures are taken to transfer the material in a safe and contained manner to the autoclave chamber. A Class III cabinet line or contained suite in which the work is performed, and to which the autoclave chamber has direct access provides excellent containment security, but is not conducive to the processing of more than a few litres at a time. Transport of liquid in a leak-proof secondary container permits larger volumes to be handled, but consideration must be given to the logistical problems associated with the transport, especially if the autoclave is situated in a relatively remote location, or is inside another suite. If the autoclave has one door only, procedures must be adopted to ensure that contaminated and safe materials are not mixed. Double door autoclaves permit the uni-directional flow of waste out of the facility, and in the UK are recommended or mandatory for the higher categories of containment. " ... 

As new campaigns began in early 1944, it became obvious that it was no longer possible to start from scratch. In order to keep supplies moving, the Sixth Army Chemical Section had to know what had been expended and what was on hand. Marriott and McKinney experienced considerable difficulty in obtaining expenditure and status reports from task forces in widely scattered locations. This failure was particularly frustrating since, at the expense of much effort, they had secured service detachments or at least junior officers to accompany those task forces without chemical sections. The primary duty of these detachments was flame thrower service, but the officers were also charged... 

ATMs offer all the advantages of direct payment but minimize opportunities for discretion and rent seeking. Other advantages of ATMs include accountability, automaticity, and potential for low operating costs, as well as the added feature of increased coverage and mobility. Box 5-13 describes possible uses of ATMs and their costs, together with point of service (or point of sale) (POS) machines. A combination of the state of infrastructure (especially electricity), security considerations, and costs will determine their suitability for a particular location.
