Fire hydrant

Provide an adequate number of fire hydrants for fixed monitors for drenching the stacks with water. Stack drums 2 m from any hydrants and leave clear access. 

Regarding fires, water is the primary extinguishing agent, and it should be available in adequate supply and pressure at all of the locations in the plant. The layout for various types of installations and the appropriate recommendations are found in the standards of the National Fire Protection Association. Fire hydrants, hose lines, automatic sprinkler and water spray systems should all be a part of the permanent equipment facilities of the plant. 

Define location of fire walls, fire hydrants.

Monitors are fixed water hydrants with an attached discharge gun. They are also installed in process areas and storage tank areas. Fire hydrants and monitors are spaced 150 -250 ft apart around process units, located so that all areas of the plant can be covered by 2 streams. The monitor is usually located 50 ft from the equipment being protected.14 Fire monitors discharge water at a rate of 500-2000 gpm.

Fire fighting equipment should be mounted at heights that are easily accessible by the average person. This includes portable fire extinguishers, hose connections to fire hydrants, access to emergency shutoff valves, emergency stop/ESD push buttons, etc. 

Red a. Stop buttons or electrical switches used for emergency stopping of machines. b. Emergency stop handles or bars on machines. c. Hazardous operation indicating lights on control, alarm panels, or in the installation. d. Fire protection equipment and systems (e g., fire hydrants, monitors, reels, alarms, etc.). e. Portable flammable liquid containers. f. Stop condition. g. Identification of ESD isolation valves and actuators. 

Water distribution within a facility involves fire mains, valves and fittings, and fire hydrants and monitors. 

The local fire department arrivedjust after the explosion at 11 22 A.M. With the limited water supply on two of the fire trucks and the utilization of another fire truck to pump water directly from a nearby cooling water tower basin, the firemen were able to slow the fire spread. By 11 30 A.M., the Maintenance Department was able to transfer the set of batteries from the impaired diesel fire pump to the other diesel fire pump. On completion of this task, this diesel fire pump was started. The automatic deluge sprinkler protection was severely damaged by the fire/explosions and had to be valved into the off position. Three fixed monitors were turned onto lull flow and directed at the fire. Also, the firemen and fire brigade used two hose streams olF nearby fire hydrants for fire fighting purposes. At 11 58 A.M., the fire was under control. Final fire extinguishment was accomplished by 12 10 p.m.

Firefighters must routinely fight structure fires that require more water than is carried on the fire truck. Water must be obtained from a fire hydrant. This water is fed through fire hoses to the truck holding tank and then pumped through additional hoses to the fire as needed. Several mechanical devices are used in this process. 

The tops and caps of your department s fire hydrants have a hexagonal stud extending about an inch from the base. Which of the following basic tools could you use to open the hydrant or remove the cap ... 

Preplans are similar to floor plans except they will often show features on the outside of the building in addition to the floor plan, although they may have somewhat less detail on the interior of the building. Preplans are frequently made for businesses, churches, and similar types of commercial buildings. These plans are often carried on the trucks for reference by the crews at an incident. A preplan may include information on access roads around the building, connections to sprinkler systems, location of gas or bulk material storage, locations of fire hydrants, information on alarm systems in the building, and other critical information for the crews.

Antoine Lavoisier, shown here with his wife, Marie-Anne, who assisted him in many of his experiments, was a concerned citizen as well as a first-rate scientist. He established free schools, advocated the use of fire hydrants, and designed street lamps to make travel through urban neighborhoods safer at night. To help finance his scientific projects, Lavoisier took part-time employment as a tax collector. Because of this employment, he was beheaded in 1794 during the French Revolution. Soon after his execution, however, the French government was erecting statues in his honor. 

One of the initial requirements made of the Modesto Project was installation of a comprehensive fire system. The large and unwieldy tire pile was surrounded by an underground sprinkler system and fire hydrants. Further, tire removal from the pile follows a carefully drafted plan to result in optimal fire lanes among the tires.1...

It is also a best practice to collect run-off water from the plant area and treat it in the site waste water plant before discharging it to the environment. Run-off water can come from rain, fire hydrant flushing, and equipment washing. As the water flows over the ground around the plant, it can become contaminated with organic chemicals that have leaked from the plant. Most plants are designed so that all the run-off is collected into local sewers or ditches that are routed to the site waste water treatment plant. 

Deininger (2000) also described potential attack points to our water-supply system upstream of the water intake or treatment plant (which would require large amounts of contaminant) the water intake or treatment plant a service reservoir and a point in the distribution system such as a fire hydrant. Individual houses and buildings, not isolated by backflow prevention devices, could also become attack points to the distribution system. He also concluded that there would be greater chances of success if contamination occurred after the treatment plant. There are many and varied agents that could be introduced into water-supply systems, and any one of the contaminants, or even the threat of contamination of the water supply, could cause panic, societal and political dismption. 

Samples were collected from eight fire hydrants of drinking water distribution net on three separate occasions, in May, July and September, 2004 (see Results and discussion). Before filling bottles we have opened fire hydrants to maximum rate of flow for two minutes to flush off biofilms from the walls of pipes and to aviod stagnant water sampling.
