POWER OUTAGE — TIME AND TEMPERATURE RECORD Original household recording aid. Not an automatic food-safety calculator. Use current local public-health instructions and the relevant food category. Never taste food to test safety. Later cooling cannot erase earlier exposure. EVENT TIMELINE — KEEP THE DATE WITH EVERY TIME Outage discovered / source of this information: Outage actually began / exact, estimated, or unknown: Last known power-on time, if actual start is unknown: Refrigerator / freezer identity: Doors stayed closed / known openings / unknown period: Transfer to cooler or another appliance / time / what was transferred: Power restored / exact, estimated, or unknown: Floodwater, sewage, other contamination, or local notice: ONE READING PER ENTRY — DO NOT MERGE AIR AND FOOD READINGS Date and time measured: Time this note was written, if different: Food / package / appliance or cooler identity: Measured target: appliance air / cooler air / particular food: Reading and unit, exactly as displayed (F or C): Device used / measurement location / method: Method followed the device instructions / uncertainty or error: Reading before or after power restoration or transfer: Earlier exposure actually documented by this reading: Earlier intervals this reading does NOT document: ITEM HISTORY AND NEXT ACTION Food name / ingredients or filling / refrigerated or frozen category: Known relevant exposure interval / evidence: Unknown interval / last known condition / next known condition: Official source and exact food-category row / checked date: Applicable condition and category-specific action: Action taken / time / person recording: Do not infer a continuous safe history from isolated cold readings. Do not reset an exposure clock after transfer or restored cooling. Keep contamination separate from an ordinary loss-of-cooling question.
