Training focus

What this guide should teach

  • Help firefighters understand why the engine may support a sprinkler system through the FDC.
  • Separate sprinkler support from standpipe attack-line support.
  • Discuss fireground signs: water flow alarm, control valve, FDC caps, and impairment indicators.
  • Emphasize SOP and command direction before shutting valves or changing system status.
Station use

Fast drill setup

Pick one objective.Do not teach the whole standard in one drill. Pick the part that matches your apparatus and staffing.
Set local conditions.Use your hose loads, pressure policy, equipment inventory, and safety rules.
Have students explain why.Make the student say what they are checking, calculating, or correcting.
Debrief common mistakes.Use the mistake list below as the after-action review starter.
Checklist

Instructor / engineer review

Use this as a quick station drill checklist. Adjust it to local SOP and equipment.

Review items

  • Correct sprinkler FDC is located, accessed, and supplied per department policy.
  • FDC caps, threads, swivels, and obstructions are checked before connection.
  • Engineer understands whether the system is sprinkler-only, standpipe-only, or combined.
  • Water supply is adequate for sustained support.
  • Crews avoid shutting control valves unless directed through command/SOP.

Common mistakes

  • Pumping the wrong FDC or confusing multiple building connections.
  • Treating sprinkler FDC pressure the same as an interior standpipe attack line.
  • Missing a closed, damaged, or obstructed FDC connection.
  • Stopping sprinkler water too early without command direction.
