Got another blog tip in the mailbag today...this time it's an excellent blog on US 40 specifically the National Pike in Maryland and Pennsylvania. It's called, '125 N to B: The National Pike and National Road' and is run by Christopher Busta-Peck. Check it out!
...and here's why. You will find White, Red, Yellow and Violet colored fire hydrants pretty much everywhere. But there's a reason for this - and it's because of the National Fire Protection Association (NFPA). This association has issued guidelines for color coding standards for fire hydrants. These color codes from the body of the hydrant, top of the hydrant, and in some municipalities the outlet caps are designed to allow fire fighters to know what type of system, water flow rate (Gallons Per Minute or GPM), and level of water pressure. This guideline is known as NFPA 291 and is intended to be used universally throughout the United States. The NFPA guidelines are specific to the body and the top cap of the hydrant. If a hydrant is WHITE or YELLOW - it means that it is connected to a public/municipal water system. If a hydrant is RED - the hydrant is connected to a private system, typically a well. These are most common in rural or unincorporated areas
