Placard
A placard is a notice installed in a public place, like a small card, sign, or plaque. It can be attached to or hung from a vehicle or building A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and func ... to indicate information about the vehicle operator or contents of a vehicle or building. It can also refer to paperboard signs or notice carried by picketers or demonstrators. Buildings A placard is posted on buildings to communicate a wide variety of information, such as fire safety policies, emergency shelters. The International Building Code requires doors in some public and commercial structures, fitted with an internal key lock have a notice "This door to remain unlocked when this space is occupied" in a minimum of text be posted beside or above the door. Some state and local bui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NFPA 704
"NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response" is a standard maintained by the U.S.-based National Fire Protection Association. First "tentatively adopted as a guide" in 1960, and revised several times since then, it defines the colloquial "Safety Square" or "Fire Diamond" which is used by emergency personnel to quickly and easily identify the risks posed by hazardous materials. This helps determine what, if any, special equipment should be used, procedures followed, or precautions taken during the initial stages of an emergency response. It is an internationally accepted safety standard, and is crucial while transporting chemicals. Codes The four divisions are typically color-coded with red on top indicating flammability, blue on the left indicating level of health hazard, yellow on the right for chemical reactivity, and white containing codes for special hazards. Each of health, flammability and reactivity is rated on a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fallout Shelters
A fallout shelter is an enclosed space specially designated to protect occupants from radioactive debris or fallout resulting from a nuclear explosion. Many such shelters were constructed as civil defense measures during the Cold War. During a nuclear explosion, matter vaporized in the resulting fireball is exposed to neutrons from the explosion, absorbs them, and becomes radioactive. When this material condenses in the rain, it forms dust and light sandy materials that resemble ground pumice. The fallout emits alpha and beta particles, as well as gamma rays. Much of this highly radioactive material falls to Earth, subjecting anything within the line of sight to radiation, becoming a significant hazard. A fallout shelter is designed to allow its occupants to minimize exposure to harmful fallout until radioactivity has decayed to a safer level. History North America During the Cold War, many countries built fallout shelters for high-ranking government officials a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Blakeley
Robert Wilson Blakeley (August 30, 1922 – October 25, 2017) was an American graphic designer, known for making the fallout shelter sign. While working for the Army Corps of Engineers, Blakeley designed the sign as a civil defense measure during the Cold War. Born in Ogden, Utah, Blakeley attended public schools and served with the Marine Corps, seeing combat during World War II. He graduated from the University of California, Berkeley, in 1954 and was the president of Toastmasters. Personal life Blakeley was born on August 30, 1922, in Ogden, Utah, to Robert G. Blakeley and Elsie Jean (Wilson) Blakeley. One of four children, he attended Weber College and Utah State University. In 1944, he married Shirley Jeane Brown, with whom he had one son, David Bruce Eppenberger. Robert and Jeane divorced some time later. In 1952, he married Dorothy McArthur, with whom he had two children, Dorothy "Dot" Carver and Robert. She died in 1992. In 2003, he married Irene Allan Davis. Blak ...

Fire Alarm Notification Appliance
A fire alarm notification appliance is an active fire protection component of a fire alarm system. A notification appliance may use audible, visible, or other stimuli to alert the occupants of a fire or other emergency condition requiring action. Audible appliances have been in use longer than any other method of notification. Initially, all appliances were either electromechanical horns or electric bells, which would later be replaced by electronic sounders. Most of today's appliances produce sound pressure levels between 45 and 120 decibels at ten feet. Methods of notification The primary function of the notification appliance is to alert persons at risk. Several methods are used and documented in industry specifications published by UL. Alerting methods include: * Sound (audible signals) ** ~3 kHz / ~3100 Hz tone (high frequency). Used in many current notification devices. ** 520 Hz (low frequency). Used in newer notification devices. ** 45 dB to 120&n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manual Fire Alarm Activation
Manual fire alarm activation is typically achieved through the use of a pull station (USA & Canada) or call point (Europe, Australia, and Asia), which then sounds the evacuation alarm for the relevant building or zone. Manual fire alarm activation requires human intervention, as distinct from automatic fire alarm activation such as that provided through the use of heat detectors and smoke detectors. It is, however, possible for call points/pull stations to be used in conjunction with automatic detection as part of the overall fire detection and alarm system. Systems in completed buildings tend to be wired in and include a control panel. Systems for use during construction can also be wireless or mechanical, it is recommended by the Structural Timber Association in the UK that for timber-framed constructions, interconnecting wireless systems be used. Fire alarm pull station A fire alarm pull station is an active fire protection device, usually wall-mounted, that, when a ...

Fire Alarm System
A fire alarm system warns people when smoke, fire, carbon monoxide or other fire-related or general notification emergency, emergencies are detected. These alarms may be activated automatically from smoke detectors and heat detectors or may also be activated via manual fire alarm activation devices such as manual call points or pull stations. Alarms can be either motorized bells or wall mountable sounders or horns. They can also be speaker strobes which sound an alarm, followed by a voice evacuation message which warns people inside the building not to use the elevators. Fire alarm sounders can be set to certain frequencies and different tones including low, medium, and high, depending on the country and manufacturer of the device. Most fire alarm systems in Europe sound like a siren with alternating frequencies. Fire alarm electronic devices are known as horns in the United States and Canada and can be either continuous or set to different codes. Fire alarm warning devices can al ...

Fire Sprinkler
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standpipe (firefighting)
In North America, a standpipe is a type of rigid water piping which is built into multi-story buildings in a vertical position, or into bridges in a horizontal position, to which fire hoses can be connected, allowing manual application of water to the fire. Within the context of a building or bridge, a standpipe serves the same purpose as a fire hydrant. In many other countries, hydrants in streets are below ground level. Fire trucks carry standpipes and key, and there are bars on the truck. The bar is used to lift a cover in the road, exposing the hydrant. The standpipe is then "sunk" into the hydrant, and the hose is connected to the exposed ends of the standpipe. The bar is then combined with the key, and is used to turn the hydrant on and off. Dry standpipe When standpipes are fixed into buildings, the pipe is in place permanently with an intake usually located near a road or driveway, so that a fire engine can supply water to the system. The standpipe extends into the b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firefighters
A firefighter is a first responder and rescuer extensively trained in firefighting, primarily to extinguish hazardous fires that threaten life, property, and the environment as well as to rescue people and in some cases or jurisdictions also animals from dangerous situations. Male firefighters are sometimes referred to as firemen (and, less commonly, a female firefighter as firewoman). The fire service, also known in some countries as the fire brigade or fire department, is one of the three main emergency services. From urban areas to aboard ships, firefighters have become ubiquitous around the world. The skills required for safe operations are regularly practised during training evaluations throughout a firefighter's career. Initial firefighting skills are normally taught through local, regional or state-approved fire academies or training courses. Depending on the requirements of a department, additional skills and certifications such as technical rescue and pre-hospita ...
