In Denver, what color is used to mark hydrants with a flow of over 1,500 GPM?

In Denver, hydrants with a flow of over 1,500 gallons per minute (GPM) are marked with blue. This color-coding system is designed to provide quick and essential information to fire personnel about water availability and hydrant performance during emergencies. Blue indicates that the hydrant can deliver a high volume of water, which is crucial for addressing large fires effectively.

The use of this specific color helps firefighters quickly identify which hydrants can provide sufficient water flow to combat significant fire incidents, allowing them to make informed decisions about where to connect hoses and allocate resources during an emergency response.

Understanding the color-coding system for hydrants is vital for fire department operations, as it supports quick access to reliable water sources, which is a critical factor in firefighting success.
