Final answer:

The NFPA 1710 does not specify fire attack flow rates based solely on the square footage of a residence. Firefighting flow rates are determined by a combination of factors including fire size, conditions, and building materials.

Step-by-step explanation:

The question pertains to the National Fire Protection Association (NFPA) 1710 standard, which specifies the minimum initial flow rate for a fire attack in a specific context. However, neither NFPA 1710 nor usual documentation on firefighting specifies flow rates based on square footage alone, without considering fire conditions, construction materials, or fire compartmentation.

In a practical situation, fire departments determine the necessary flow rate using various factors including the size of the structure, the fire load, the potential for fire spread, and the effectiveness of the attack technique.

Nonetheless, there is a general guideline known as the Iowa formula (GPM = Length x Width / 3 for residential structures), which could suggest that for a 2000 ft² (around 186 m²) single-family dwelling, an approximate starting flow rate might be near 100 GPM. Keep in mind, this is not directly from NFPA 1710, and actual strategies and required flow rates might differ.

To obtain specific information regarding NFPA standards, it is advisable to consult the latest edition of NFPA 1710 or contact your local fire department for criteria based on your area's firefighting protocols.
