Control buildings location

Refer to API RP 752 and Cuidelines for Facility Siting and Layout (CCPS, 2003c) for additional guidance on control building location. 

Fugitive emissions from charging and tapping of EAFs should be controlled by locating the EAF in an enclosed building or using hoods and by evacuating the dust to dust arrestment equipment to achieve an emissions level of less than 0.25 kg/t. 

Outside location of process units or equipment required separate control buildings. Initially, their function was limited to displaying process variables. 

A control building is located 125 ft (38 m) from a facility that handles highly reactive materials having the potential for explosion. The building can withstand a 12 psi (0.83 bar) side-on overpressure, 20 ms blast load. 

The company standards classify this facility as "high explosion potential," requiring control buildings that are located at this distance [125 ft (38 m)] from a potential explosion be designed to a minimum load of 10 psi (0.69 bar) side-on overpressure and 20 ms blast load. It was determined that this... 

Denver, Colorado (Refs. 16 and 19) 3 (0 in buildings) A propane release at a polymerization unit in a process plant resulted in a blast that destroyed the process unit. The blast-resistant control house, located only 98 ft (30 m) from the blast center, sustained little damage. 

The location of a control building should be selected with care to ensure that it is exposed to minimal hazards from the processing facility it serves as well as all adjacent units and external facilities. 

Additional analyses are required and special building design features may be needed if the control building in its planned or existing location is exposed to more severe hazards, such as ... 

The control console, located in the center.of the reactor control room (see Section 5.7.1), is made up of five unit panels laid out on a circular arc of 51 in. radius and extending some 240°. At the center of this arc, the operator will be seated in a movable chair, giving him easy access to the information and control elements spread out on the panels. At his left hand is a telephone by which he can communicate with other control and instrument centers, such as the one in the Process Water Building. By looking over the top of the console, which is 40 in. from the floor, he can see the instrument panels, particularly panels D to H, standing in an arc directly in front of him. 

Institutions may consider applying concepts of crime prevention through environmental design. Building location and properly placed en-tryways, windows, lighting, shrubbery, and other physical features can help deter criminal activity, and are cost-effective, systemic improvements that do not depend solely on technology. The security and access control policy should be the basis of the site security plan. 

Reactor auxiliary building is located very near to the RB to avoid long piping lengths. A separate control building has been provided as a common facility. However, the control room and control equipment rooms in this building are so laid out as to cater... 

Other project management systems include planning for end points of a project with passive versus active solutions to minimize large legacy costs. One example would be to plant trees in strategic locations to reduce HVAC requirements for temperature controlled buildings. Another example specific to D D is to install a series of shallow ponds on a property to slow runoff for monitoring purposes in case a cleaned site has future contamination issues or to slow and/or concentrate the movement of contamination should it occur. 

Main and multiunit substations should not be part of administration buildings, shops, control buildings, laboratories, or any other nonrelated structure. In locations where it is deemed absolutely necessary to combine a main or multiunit substation with another structure, the substation should be separated by a 3-hour rated firewall with no direct access or any other penetration through the wall. 

Process-unit control houses should be located at the periphery of the process unit. The structural members and the interior and exterior walls of control buildings should be constructed of noncombustible materials. 

Positive, forced-air ventilation should be provided. The air intake should be taken from a safe, vapor-free location at least 10 meters above grade. If hydrogen sulfide, hydrocarbons, or other toxic or hazardous vapors could be drawn in by the air system, a vapor detection system should be provided. This system should alarm personnel in the control building at 20% lower flammable limit (LFL) and start 100% circulation at 60% LFL. 

In freezing climates, the strainer, control valve manifold, and necessary system drains should either be located in a heated area within the control building, in a heated cubicle, or be insulated and heat traced. 

Access to the powerhouse is by a 5200 ft long vehicular tunnel, or by lift down a 900 ft deep shaft from the control and administration building located on the surface close to the switchyard. 

EPIPs were available in the OSC, and the staff was told that plant equipment documents (e.g., prints, drawings, operations procedures, etc.) could be obtained from the Satellite Document Control Center located in the Reactor Area 105 building. The document control staff is responsible for ensuring the readiness condition of the Satellite Document Control Center. Additionally, the maintenance shops are located near the OSC, where additional equipment, prints, etc., can be obtained for emergency use.
