Heating season is back, and so is carbon monoxide

This is a seasonal outlook, not a forecast for a named storm, and no agency has issued a specific warning that is being passed along here. The point is the calendar: early November is when furnaces, boilers, space heaters, and generators come back online across most jurisdictions, and the call pattern shifts with them.

Carbon monoxide is the first thing that changes. The classic presentation is a household reporting flu-like symptoms that improve when they leave the structure. Dispatch should flag multiple occupants with the same complaint in one address as a possible CO job, not a medical cluster. For fire and EMS, the hazard is that the first crew in can be exposed before anyone meters the air. Treat the detector activation and the vague headache call as the same category until the readings say otherwise.

Cold stress starts low and builds through the season. The at-risk calls are the ones that don't announce themselves: the unsheltered person found down, the older adult in an underheated home, the outdoor worker who kept going past the point of good judgment. Altered mental status in the cold is hypothermia until proven otherwise.

Early ice is the trap that catches people who think it is still fall. Thin ice on ponds and retention basins draws kids and dogs, and the rescues that follow put responders on the ice too. Ice-rescue capability and cold-water protocols should be confirmed now, before the first through-the-ice call, not during it.

Generators move indoors and into attached garages when the power flickers. That is the overlap where CO and cold meet, and it is where whole families go down at once.

Check your own gear this week: metering, cold-weather PPE, and the heater in the apparatus bay. The season does not wait for you to be ready for it.
