Fire hydrants should be flushed prior to every use, before the hose is connected. Most municipalities have a maintenance program in effect, whereby each fire hydrant is inspected, flushed, greased, and winterized(in cold climate areas) annually.

What is the NFPA definition of what is the maximum distance a fire department connection can be from a fire hydrant?
The FDC and hydrant aren't something that connect directly together. In order to put any kind of water pressure into a sprinkler system, an engine HAS to pump it in. Therefore, as long as the fire apparatus has enough hose, or can GET the hose from other apparatus the hydrant could hypothetically be a block away. There may be problems with friction loss with any large distances though. In my local area, the fire department has a maximum of 150 feet from the FDC to the Fire hydrant.
In California how many feet can you park next to fire hydrant?
As long as you aren't parked next to it your OK. Parking in front or behind is fine as long as it doesn't block it.
How long will it take to cook a hot dog in space?
You need oxygen to create fire, (or rather heat) to cook. Though it is possible, I think you'd just eat a anti-hydrant hot-dog.
How long is a fire departments fire hose?
The hoses used by a fire department come in 50 ft. sections. These sections are put together to create a length any where from 50 - 1000 feet. Supply lines are used to supply water from a hydrant to the fire truck, and come in 100 ft. sections which can create any length as needed. Supply lines have been as long as 2000 ft.
when antifreeze is brown should you flush the coolant?
If you waited until the coolant is brown you waited too long. Have the system professionally flushed at that point.
How long should a fire drill last?
Should last about 30 minutez
Should the transmission be flushed fluid and filter changed on a 1986 Ford econoline 350 motorhome with engine 460?
Yes - probably a long time ago
Can the seals be replaced in a hydrant without digging it up?
Fire hydrant that usally leak at the base need to be service by replacing the main gate rubber That depends on the location of the leak. The seals on the part that turns it on at the top can be replaced without digging as long as the water supply to the hydrant can be shut off at another location. The hydrant is bolted to a flange which is attached to an underground pipe which itself probably has a few more underground that you cannot see. Between the hydrant and the flange is a gasket, now if this gasket is leaking the hydrant will need to come off. Sometimes the bolts are exposed but not always. Then if it is a fitting below that is leaking then some major excavation will need to be done. I just recently did a repair on a 12 inch line here at the golf course and the hole was quite large as the pipe was nearly ten feet under the surface at the leak. Pinpointing the exact location of the leak is a problem as well.
How does the fire department connect to a fire hydrant?
There is a suction line on every apparatus with a pump. The engineer, who drives the rig, connects this line to the hydrant and to the pump suction. Some equipment has this line pre-connected to the pump inlet. In many fire hydrant systems there is enough pressure to fill and pressurize an ordinary hose (of large diameter) running from the hydrant to the pumper truck's inlet. That way, there is very little "suction" required in the pump, since the water is already being delivered with some amount of pressure. If it is "dry hydrant" with no pressure, then suction is required. Edit: Typically it is a Firefighter that 'snubs' the hydrant, not the Engineer. It is the Engineer's job to 'Position' the apparatus before transferring the engine into 'Pump' (typically, once the apparatus engine is transferred to 'Pump', it is stationary throughout the incident). There are different options for water 'Intake', they can be long leads whereby a supply line can be a smaller diameter (2 1/2") or a 'Short Sleeve' (4") direct to pump diameter where the Pumper is 'Positioned' close to the hydrant snubbed. There are also situational logistics which require two Pumpers (or more) to 'Relay' a supply line due to the fact that the total amount of hose on a given Pumper is less then the distance from the fire to the hydrant. It is the Engineer's job to figure out what pressure is incoming from the supply line and the amount of nozzle pressure required for firefighting at the nozzle. This determines what pressure you need to be pumping at. This pumping pressure must take into consideration elevation, friction loss of pressure in the amount of hose laid out, etc. It can be a life or death calculation for the Firefighter at the nozzle's fighting end which could very well be 40 stories above the Engineer manning the pump.
How do you maintain an automatic gearbox serviceable for long?
An automatic gearbox is maintained to keep it serviceable for a long time by changing the fluid and filters at regular intervals. The entire system should also be flushed periodically to remove contaminants.
How long you have to do fire drills?
The drill should only last 10-15 minutes.
Will your homeowners insurance rates increase if your local fire dept closes?
It is very possible that this will cause your insurance rates to increase but it could actually cause your rates to decrease as well. You are rated based on the closest fire department to you as long as you are within 5 driving miles of the fire department and have a fire hydrant within 1000 feet of your home. If a class 9 volunteer fire department closes that is 1/2 mile from your house and now the closest is a class 6 full time fire department then your rates will drop in half. So it depends on the situation.
