Heating season starts now — the hazards shift from heat to cold, smoke and short days

This is a seasonal outlook, not a forecast for your area. Pull your own local forecast and any watches or warnings from your jurisdiction's weather service before shift. The point here is the pattern that comes with late October: the same addresses that ran heat and dehydration calls through summer start running heating calls instead.

Heating equipment comes back online. That means the first hard cold night usually brings a cluster of furnace, chimney, wood-stove and space-heater fires, and the carbon monoxide calls that ride alongside them. CO moves with the weather — a cold snap that drives people to seal up and run unvented heat is the setup. Treat an unexplained group of occupants with headache, nausea or syncope in a closed building as CO until a meter says otherwise, and meter on arrival rather than on suspicion.

Cold changes the scene itself. Patients down outdoors cool faster than the air temperature suggests once wind and wet ground are in play, and extrication in the cold stalls when gear and hands stiffen. The exposure risk is not only the patient's; crews working a long roadway or wildland-interface incident lose dexterity and judgment before they notice it. Rotate people and watch for it.

Shorter daylight is its own hazard. Roadway operations now run in the dark on both ends of a day shift, so lighting, high-visibility gear and lane protection matter earlier than they did a month ago. Falling leaves hide pavement markings and clog drainage, which turns an ordinary rain into standing water and a routine response into a slower one.

None of this is new to you. The value is in setting it up before the weather does. Confirm heating-related resources, CO meters and cold-weather gear are checked now, while the calls are still light, so the first cold night finds you ready rather than catching up.
