Week 2 Battery Risk Log

Week 2 ends with a decision log, not a diary entry.

Use the fictional swollen-pack incident from this week and produce a record that another student could read tomorrow without needing you beside them.

Your final battery decision

Write one paragraph that answers all four questions:

  • What abnormal evidence was present?
  • Which normal-service assumption did that evidence break?
  • What disposition did you choose: normal service, hold for review, or no-go?
  • Why did you choose it without needing to prove the exact internal battery failure?

Keep the distinction between condition and function visible. A pack previously providing power is not the same thing as current evidence supporting normal use.

Evidence ledger

Create a compact table:

Evidence sourceWhat it actually showsWhat it does not prove
supplied storage photo
prior incident / landing note
label or identification record
charger or storage record

Add one more evidence source from the lesson packet.

One boundary you would never erase

Complete this sentence with a specific condition:

Normal battery service stops when...

Then explain why that condition is a gate, not merely a suggestion.

Incident-review reflection

Answer these three prompts in two or three sentences each:

  1. Which observation was easiest to over-interpret, and what stronger wording did you use instead?
  2. Which corrective control would improve the system most: labeling/status, history tracking, setup documentation, or escalation ownership? Defend one choice.
  3. What evidence would you still need before making a stronger root-cause claim?

Exit standard

Your log is complete when it shows a clear no-go or review boundary, separates observations from assumptions, and leaves one honest statement about what the evidence cannot prove.
