Understanding the Harris County Fire Flow Calculator
The Harris County Fire Flow Calculator is a vital tool used to determine the adequacy of water supply for firefighting purposes at specific locations. This calculator evaluates whether the available water flow meets the requirements set forth by the Harris County Fire Code. It is essential for ensuring that buildings are equipped with sufficient water supply for fire safety.
Key components of the calculator include:
- Property Address: The location where the water flow will be assessed.
- Building Specifications: Information such as height and square footage, which influence water demand.
- Construction Type: The materials used in the building, affecting fire risk and water needs.
- Available Water Flow Rate: The measurement of water flow from the nearest hydrant at a residual pressure of twenty psi.
Steps to Use the Harris County Fire Flow Calculator
Using the Harris County Fire Flow Calculator involves several straightforward steps. Each step is crucial for accurate results.
1. **Access the Calculator:** Obtain the form or spreadsheet version of the calculator from the Harris County Fire Marshal's office or their website.
2. **Input Property Address:** Enter the complete address of the property being evaluated. This helps in identifying the nearest water source.
3. **Enter Building Specifications:** Provide details such as the height of the building and the total square footage. For example, a two-story building may have different requirements than a single-story structure.
4. **Specify Construction Type:** Indicate the type of construction, such as wood, metal, or masonry. This information is essential as different materials have varying fire resistance levels.
5. **Measure Water Flow Rate:** Use a flow meter to determine the available water flow from the nearest hydrant at a residual pressure of twenty psi. Accurate measurement is critical for reliable results.
6. **Calculate Results:** The calculator will process the input data and provide an output indicating whether the available water flow is sufficient for firefighting needs.
