Safety Curtain
A safety curtain (or fire curtain in America) is a fire safety precaution used in large proscenium Theater (structure), theatres. It is usually a heavy fibreglass or iron curtain located immediately behind the proscenium arch. Asbestos-based materials were originally used to manufacture the curtain, before the dangers of asbestos were widely known. The safety curtain is sometimes referred to as an iron in British theatres, regardless of the actual construction material. Occupational safety and health regulations state that the safety curtain must be able to resist fire and thereby prevent (or at least hinder) fires starting on stage from spreading to the auditorium and the rest of the theatre, reducing injuries to Patrons, audience members and members of staff. The curtain is extremely heavy and therefore requires its own dedicated operating mechanisms. In an emergency, the Stage management, stage manager can usually pull a lever backstage which will cause the curtain to fall ...

Intermission
An intermission, also known as an interval in British and Indian English, is a recess between parts of a performance or production, such as for a theatrical play, opera, concert, or film screening. It should not be confused with an entr'acte (French: "between acts"), which, in the 18th century, was a sung, danced, spoken, or musical performance that occurs between any two acts, that is unrelated to the main performance, and that thus in the world of opera and musical theater became an orchestral performance that spans an intermission and leads, without a break, into the next act. Jean-François Marmontel and Denis Diderot both viewed the intermission as a period in which the action did not in fact stop, but continued off-stage. "The interval is a rest for the spectators; not for the action," wrote Marmontel in 1763. "The characters are deemed to continue acting during the interval from one act to another." However, intermissions are more than just dramatic pauses that are parts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Backdraft
A backdraft (North American English) or backdraught (British English) is the abrupt burning of superheated gasses in a fire, caused when oxygen rapidly enters a hot, oxygen-depleted environment; for example, when a window or door to an enclosed space is opened or broken. Backdrafts present a serious threat to firefighters. There is some debate concerning whether backdrafts should be considered a type of flashover (see below). Burning When material is heated enough, it begins to break down into smaller compounds, including hydrogen. This is called pyrolysis, and does not require oxygen. If oxygen is also provided, then the hydrogen can combust, starting a fire. If material undergoing pyrolysis is later given sufficient oxygen, the hydrogen gas will ignite, and therefore, combustion takes place. Cause A backdraft can occur when a compartment fire has little or no ventilation. Due to this, little or no oxygen can flow into the compartment. Then, because fires reduce oxygen, the ...

Proscenium Arch
A proscenium ( grc-gre, προσκήνιον, ) is the metaphorical vertical plane of space in a theatre, usually surrounded on the top and sides by a physical proscenium arch (whether or not truly "arched") and on the bottom by the stage floor itself, which serves as the frame into which the audience observes from a more or less unified angle the events taking place upon the stage during a theatrical performance. The concept of the fourth wall of the theatre stage space that faces the audience is essentially the same. It can be considered as a social construct which divides the actors and their stage-world from the audience which has come to witness it. But since the curtain usually comes down just behind the proscenium arch, it has a physical reality when the curtain is down, hiding the stage from view. The same plane also includes the drop, in traditional theatres of modern times, from the stage level to the "stalls" level of the audience, which was the original meaning of t ...

Sprinkler Head
A fire sprinkler or sprinkler head is the component of a fire sprinkler system that discharges water when the effects of a fire have been detected, such as when a predetermined temperature has been exceeded. Fire sprinklers are extensively used worldwide, with over 40 million sprinkler heads fitted each year. In buildings protected by properly designed and maintained fire sprinklers, over 99% of fires were controlled by fire sprinklers alone. History In 1812, British inventor Sir William Congreve patented a manual sprinkler system using perforated pipes along the ceiling. When someone noticed a fire, a valve outside the building could be opened to send water through the pipes. It was not until a short time later that, as a result of a large furniture factory that repeatedly burned down, Hiram Stevens Maxim was consulted on how to prevent a recurrence and invented the first automatic fire sprinkler. It would douse the areas that were on fire and report the fire to the fire sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flood
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees, and larger environmental issues such as climate change and sea level rise. In particular climate change's increased rainfall and extreme weather events increases the severity of other causes for flooding, resulting in more intense floods and increased flood risk. Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting ...

Smoke
Smoke is a suspension of airborne particulates and gases emitted when a material undergoes combustion or pyrolysis, together with the quantity of air that is entrained or otherwise mixed into the mass. It is commonly an unwanted by-product of fires (including stoves, candles, internal combustion engines, oil lamps, and fireplaces), but may also be used for pest control ( fumigation), communication ( smoke signals), defensive and offensive capabilities in the military (smoke screen), cooking, or smoking (tobacco, cannabis, etc.). It is used in rituals where incense, sage, or resin is burned to produce a smell for spiritual or magical purposes. It can also be a flavoring agent and preservative. Smoke inhalation is the primary cause of death in victims of indoor fires. The smoke kills by a combination of thermal damage, poisoning and pulmonary irritation caused by carbon monoxide, hydrogen cyanide and other combustion products. Smoke is an aerosol (or mist) of solid particl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Door
A fire door is a door with a fire-resistance rating (sometimes referred to as a ''fire protection rating'' for closures) used as part of a passive fire protection system to reduce the spread of fire and smoke between separate compartments of a structure and to enable safe egress from a building or structure or ship. In North American building codes, it, along with fire dampers, is often referred to as a closure, which can be derated compared against the fire separation that contains it, provided that this barrier is not a firewall or an occupancy separation. In Europe national standards for fire doors have been harmonised with the introduction of the new standard EN 16034, which refers to fire doors as fire-resisting door sets. Starting September 2016, a common CE marking procedure was available abolishing trade barriers within the European Union for these types of products. In the UK, it is Part B of the Building Regulations that sets out the minimum requirements for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iroquois Theatre Fire
The Iroquois Theatre fire occurred on December 30, 1903, at the Iroquois Theatre in Chicago, Illinois, United States. It is the deadliest theater fire and the deadliest single-building fire in U.S. history, resulting in at least 602 deaths. Theater The Iroquois Theatre was located at 24–28 West Randolph Street, between State Street and Dearborn Street, in Chicago, Illinois. The syndicate that bankrolled its construction chose the location specifically to attract women on day trips from out of town who, it was thought, would be more comfortable attending a theater near the police-patrolled Loop shopping district. The theater opened on November 23, 1903, after numerous delays due to labor unrest and, according to one writer, the unexplained inability of architect Benjamin Marshall to complete required drawings on time. Upon opening the theater was lauded by drama critics; Walter K. Hill wrote in the ''New York Clipper'' (a predecessor of ''Variety'') that the Iroquois was "the ...

Fifth Avenue Theatre
Fifth Avenue Theatre was a Broadway theatre in New York City in the United States located at 31 West 28th Street and Broadway (1185 Broadway). It was demolished in 1939. Built in 1868, it was managed by Augustin Daly in the mid-1870s. In 1877, it became the first air-conditioned theatre in the world. In 1879, it presented the world premiere of ''The Pirates of Penzance'' by Gilbert and Sullivan and the New York premiere of ''H.M.S. Pinafore'', followed by other Gilbert and Sullivan operas throughout the 1880s. The theatre continued to present both plays and musicals through the end of the century. At the beginning of the 20th century, the theatre presented English classics and then vaudeville, and later films, as well as plays and musicals. History The theatre was built in 1868 and was originally named Gilsey's Apollo Hall, in 1870 renamed the St. James Theatre. Its capacity was approximately 1,530 seats.
