A control room or operations center or operations control center (OCC) is a room serving as a central space where a large physical facility or physically dispersed service can be monitored and controlled.
A control room is a room for production control, and it serves as a central space where a large physical facility or physically dispersed service can be monitored and controlled. These kind of central control rooms came into general use in factories during the 1920s.
Control rooms for vital facilities are typically tightly secured and inaccessible to the general public. Multiple electronic displays and control panels are usually present, and there may also be a large wall-sized display area visible from all locations within the space. Some control rooms are themselves under continuous video surveillance and recording, for security and personnel accountability purposes. Many control rooms are manned on a "24/7/365" basis, and may have multiple people on duty at all times (such as implementation of a "two-man rule"), to ensure continuous vigilance.
Other more special-purpose control room spaces may be temporarily set up for special projects (such as an oceanographic exploration mission), and closed or dismantled once the project is concluded.
Examples of control rooms
- Nuclear power plants and other power-generating stations, many oil refineries and chemical plants
- Major transportation facilities, such as bridges, tunnels, canals, airports, and rapid transit systems, may have 24-hour manned control rooms to monitor and report on traffic congestion, and to respond to emergencies
- Various military facilities, ranging in scale from a missile silo to NORAD. The term "operations room" is also used.
- NASA flight controllers work in a "flight control room" in a mission control center; affiliated facilities such as the Jet Propulsion Laboratory have their own control rooms;
- Call centers use a control room to monitor incoming and outgoing communications of customer service representatives, and to provide general oversight of the call center.
- Fire service control rooms (UK). For example, see FiReControl, nine new regional control rooms to handle emergency calls in England.
- Computerized data centers, which often serve remote users in multiple time zones worldwide
- Network operations centers
- Large institutions, such as universities, hospitals, major research facilities (such as particle accelerator laboratories), high security prisons, and theme parks
- Metropolitan police or special security jurisdictions
The control room concept is also used in non-emergency contexts:
- In television production, the master control is the technical hub of a broadcast operation common among most over-the-air television stations, television networks and color suites.
- Sound recording studios typically each have their own control rooms where the recording is actually made
Special hazards and mitigation
Control rooms are usually equipped with elaborate fire suppression and security systems to safeguard their contents and occupants, and to ensure continued operation in emergencies. In hazardous environments, the control room may also serve as an area of refuge for personnel trapped onsite. The rooms are typically crammed with equipment, mounted in multi-function rack mount cabinets to allow updating. The dense concentration of equipment often requires special electrical uninterruptible power supply (UPS) feeds and air conditioning.
Since the control equipment is intended to control other items in the surrounding facility, these (often fire-resistance rated) service rooms require many penetrations for cables. Due to routine equipment updates these penetrations are subject to frequent changes, so that a control room maintenance program must include vigilant firestop maintenance for code compliance.
Due to the nature of the sensitive equipment inside control room cabinets, it is useful to ensure the use of "T-rated" firestops, that are massive and thick enough to resist heat transmission to the inside of the control room. It is also common to place control rooms under positive pressure ventilation to prevent smoke or toxic gases from entering. If used, gaseous fire suppressants must occupy the space that is to be protected for a minimum period of time to be sure a fire can be completely extinguished. Openings in such spaces must, therefore, be kept to a minimum to prevent the escape of the suppression gas.
A mobile control room is designated as particularly in high risk facilities, such as a nuclear power station or a petrochemical facility.[further explanation needed] It can provided a guaranteed life support for the anticipated safety control.
Role of Control Room Design
|This section does not cite any references or sources. (July 2015)|
A control room has a human factor engineered design, where the human-machine interface is what it takes to control and monitor the various mission critical operations inside of it. The ergonomic and aesthetic design integrations within a control room design helps in supporting the environment of the control room as well as the health of its operators. The traffic flow, acoustics, illumination, health and safety are some of the key requisites of a control room design which contributes to the functional health of a mission critical control room.
The relationship between objects and the space they occupy within the assigned environment contributes towards spatial experience. A control room is into a spatial relationship with the humans, door, machines and furniture that contributes as objects to its environment. Spatial considerations are taken into account while designing a control room for the correct operation and interaction of the human-machine interface within a control room environment.
While designing and lay-outing a control room, ergonomic standards are taken into consideration. The placement of human-machine interface within a control room is kept in such a way that, the operators could interact with each other without any hindrances during emergency situations. The entrance and the exit of operators and their movement governed by their respective assigned work type inside a control room are planned and designed such that, to keep these to a minimum level for making the control room environment distraction free and that it does not hinder the operational tasks within a control room design.
In popular culture
Control room scenes dealing with crisis situations appear frequently in thriller novels and action films. In addition, a few documentaries have been filmed with scenes in real-life control room settings.
- The China Syndrome - a 1979 American thriller film that tells the story of a television reporter and her cameraman who discover safety coverups at a nuclear power plant. It stars Jane Fonda, Jack Lemmon and Michael Douglas, with Douglas also serving as the film's producer.
- Control Room (film) - a 2004 documentary film about Al Jazeera and its relations with the US Central Command (CENTCOM), as well as the other news organizations that covered the 2003 invasion of Iraq.
- Fail-Safe (1964 film) - a 1964 Cold war thriller film directed by Sidney Lumet, based on the 1962 novel of the same name by Eugene Burdick and Harvey Wheeler. It portrays a fictional account of a Cold War nuclear crisis.
- Minority Report (film) - a 2002 American neo-noir science fiction thriller film directed by Steven Spielberg and loosely based on the short story of the same name by Philip K. Dick. It is set primarily in Washington, D.C., and Northern Virginia in the year 2054, where "PreCrime", a specialized police department, apprehends criminals based on foreknowledge provided by three psychics called "precogs".
- The Taking of Pelham One Two Three (1974 film) - a 1974 American thriller film directed by Joseph Sargent, produced by Edgar J. Scherick, and starring Walter Matthau, Robert Shaw, Martin Balsam and Héctor Elizondo. Peter Stone adapted the screenplay, from the 1973 novel of the same name by Morton Freedgood (under the pen name John Godey) about a group of criminals taking hostage for ransom the passengers of a busy New York City subway car.
- The Prisoner - a 17-episode British television series, which follows a British former secret agent who is abducted and held prisoner in a mysterious coastal village resort where his captors try to find out why he abruptly resigned from his job.
