What steps should you take to fix or confirm a location in the Major Street Hundred Blocks system during an incident?

• A. Record the block number and street, note the quadrant, and cross-check with nearby landmarks and cross streets; verify with dispatch.
• B. Only record the street name.
• C. Call the dispatcher once and hang up.
• D. Use GPS coordinates exclusively.

Answer: (A)

In the Major Street Hundred Blocks system, pinpointing an incident location relies on a precise, layered description that can be quickly understood by responders. Start by recording the block number and the street name, because this identifies the exact segment of the major thoroughfare where the incident is occurring. Then note the quadrant, which helps place the block within the city’s grid and prevents confusion when streets or intersections span multiple areas. Next, cross-check with nearby landmarks and cross streets to confirm the spot and give responders natural reference points they can recognize on the ground. Finally, verify with dispatch so the official incident record reflects the correct location and can be reliably communicated to units en route.

Other approaches miss important pieces: recording only a street name doesn’t give a specific location; calling and hanging up loses the opportunity to confirm details; and using GPS coordinates exclusively can be unreliable in dense urban areas and doesn’t align with the grid system used for rapid coordination.
