Which NFPA standard helps instructors determine the water supply for a training fire?

The standard that assists instructors in determining the water supply for a training fire is NFPA 1142. This standard focuses specifically on the water supply requirements for fire training activities. It provides guidance on ensuring that instructors have adequate water resources for live fire training scenarios, which is critical for maintaining safety and effectiveness during training exercises.

NFPA 1142 addresses issues such as calculating the necessary water supply based on the type and scale of the training fire, as well as considerations for the environment and potential impacts on local water systems. This standard is essential for instructors to plan and conduct safe and effective live fire training, ensuring that they can meet both training objectives and safety regulations.

In contrast, other NFPA standards like NFPA 1403 relate more to the overall safety of live fire training, NFPA 1001 focuses on firefighter qualifications, and NFPA 1500 deals with fire department occupational safety and health programs, but none of these specifically target the water supply requirements for training fires as directly as NFPA 1142 does.
