Quick Start — DRA Journey
  1. 1
    Pick an exercise

    The library shows scenes that have an arrival video — click a card and choose DRA Journey, the primary action (Spot-it, Write-it and Reveal are also available on the same card).

  2. 2
    Watch your approach

    You're briefed as the Incident Commander, first on scene. Every scene opens with the information from Control. On scenes with an arrival video, click Begin approach to watch the drive-up; otherwise click Arrive at scene.

  3. 3
    Work through five stages

    Identify hazards from the scene → locate each one in the picture (click, tap, or use the arrow keys and Enter) → weigh the risk: decide what is at stake (saveable life, saveable property only, or already lost) and then what each hazard means for crews (standard procedures, additional controls, or keep crews out) → pick control measures → make command decisions (tactical mode, priorities, resources). Each stage gives immediate feedback with NOG-referenced rationale before you continue.

  4. 4
    Review your results

    The results screen scores each of the five stages separately and averages them into an overall percentage, followed by a debrief listing what you missed with rationale.

The 5 DRA Journey Stages
01
IdentifySelect every hazard you can see in the scene, from a list that mixes genuine and decoy options.
02
LocateClick or tap the scene image to pinpoint where each hazard actually is — or move a crosshair with the arrow keys and press Enter.
03
Weigh the riskAre the risks proportional to the benefits? Decide what is at stake — saveable life, saveable property only, or already lost — then what each hazard means for crews: standard procedures, additional controls, or keep crews out.
04
Control measuresPick the correct control measure for each key hazard.
05
Command decisionsDeclare tactical mode (Offensive/Defensive) with your reasoning, order tactical priorities, and select the resources you'd commit.
Other Modes
🎯
Spot-it A shorter three-stage version of the same idea (identify, rate, controls) without the narrative arrival video or the command decisions stage — the same three-stage exercise as the original HazardGrid.
✍️
Write-it A blank DRA form graded by Claude against the scene's answer key.
👁️
Reveal Instant study mode — shows the full DRA answer key with no scoring.
For Administrators
🔑
Unlocking the scene generator Append ?admin to the app URL and enter the shared admin key. This unlocks a "Generate (admin)" nav link.
🎬
Generating a new scene Pick a scenario type, hazard level, location and optional specific hazards. The scene image, DRA answer key and arrival video are generated together — this can take a few minutes.
⏱️
Daily quota Generation is rate-limited (5 per day per IP); over quota falls back to a random library scene.
Note: only scenes with an arrival video appear in the public library — new generations surface automatically once their video is ready.
