Experience Walkthrough

A Work Order will appear in front of you detailing the customer complaint. Select Show Facility Location to see where the customer's home is located on the Service Map, then walk to their home.

Once you locate the customer's house, select their door with your laser pointer and select Knock on the Door.
1. If the customer did not call, check with nearby NPCs.
Next, note all AOCs and hazards. A few examples of AOCs and Hazards that should be noted are:
1. AOCs — Damaged Meter Missing, Damaged, Severe Tilt, Corrosion, Buried
2. Hazards — Vicious Dog, “Beware of Dog” Sign, Locked Gate, Wasp Nest, Poison Ivy, Ant Hill, or Pothole
Once an AOC or Hazard is discovered, you should respond properly by reporting them through your Wrist Menu and contacting the right personnel.
After responding to AOCs and hazards, you can repair the leak.

Locate the gas leak.
1. To find the gas leak, investigate through the use of sight, sound, questioning people present at the location, and by using your tools.
2. Tools can be accessed through your Wrist Menu > Toolbox.
Once the leak is found, assess the leak’s potential for leak migration by taking CGI readings at the centerline sewer manholes, catch basins, and utility vaults.
1. If gas is found near a building wall or centerline sewer — request assistance, check all buildings for gas, and vent immediately.
Next, classify the leak.
1. Check for definitions of each leak grade within your Wrist Menu by selecting Reference Material > Leak Grade Card.
2. Grade 1 — Hazardous. Act immediately.
3. Grade 2 — Fix or re-classify within 30 days.
4. Grade 3 — Not hazardous, and is not likely to change. Check every 90 days to see if the leak is gone or needs to be re-classified.

After classifying the leak, report the leak and call for assistance if needed based on the leak’s classification.
Lastly, recheck all areas and document through the wrist menu. Select Submit with Final Report to end the scenario.
1. Tip: To submit mid-investigation findings and document hazards without ending the module, you can instead select immediately when choosing when to submit findings.
