Which of the following is NOT a component of a winter emergency kit?

A winter emergency kit is essential for ensuring safety during cold-weather travel, and it typically includes items that assist in keeping you warm, providing aid in vehicle breakdown scenarios, or assisting in emergency situations. A fire extinguisher, while useful in many circumstances, is not specifically designed for winter emergencies involving vehicle breakdowns or inclement weather.

Warm winter clothing, jumper cables, and a blanket are all components that enhance comfort and safety in winter conditions. Warm clothing helps prevent hypothermia, jumper cables can assist in starting a vehicle with a dead battery, and blankets provide warmth if stranded. Therefore, the inclusion of these items relates directly to managing health and safety in cold weather, whereas a fire extinguisher is more relevant to fire hazards rather than specific winter emergencies.
