Cold is back on the board — treat it as an operational hazard, not weather

The clocks have changed and overnight temperatures are dropping below the point where exposure starts to matter. That shifts the risk profile on routine calls, not just the dramatic ones.

Hypothermia does not need a blizzard. A patient down on a sidewalk, a trapped occupant waiting on extrication, a found person after a short search — all lose heat fast once they stop moving, and faster if they are wet or on cold ground. Mild hypothermia reads as confusion, poor coordination and slurred speech, which is easy to put down to alcohol or a head injury and miss. Get an insulating layer under the patient, not just over them, and cut wet clothing rather than peeling it.

Your own window of work gets shorter too. Manual dexterity drops before you feel cold, so the fine tasks — IV access, knots, tool handling — take longer and go wrong more often. Rotate crews earlier than you would in summer and build rehab in from the start of a long incident rather than after someone flags.

Gear behaves differently. Water on the ground, on apparatus steps and on hose freezes. Standing water from suppression turns to ice around the scene and on access routes. SCBA and tool mechanisms stiffen. Diesel and hydraulics are slower to come up to temperature. Walk your running boards before you trust them.

For drivers, the first hard frost of the season is consistently worse than the depth of winter, because the habits have lapsed. Black ice forms first on bridges, overpasses and shaded bends. Leave more distance and brake earlier on approach.

For dispatch and EM: expect heating-related calls to climb — carbon monoxide, overloaded circuits, open-flame heaters — as people bring equipment back into service that sat idle all summer. Flag CO symptoms early to responding crews so they stage their own monitoring, and watch for clusters that point to a wider utility or supply problem rather than a single address.
