Winter gives rise to many different dangerous weather conditions, such as snowstorms, reduced visibility, cold temperatures, and frigid wind chills. One dangerous weather condition combines all of these into one weather event: snow squalls!
Snow squalls are intense snowstorms that develop quickly and only persist for a brief time. One of the most dangerous aspects of snow squalls is how rapidly they develop—catching many people off-guard—and creating additional hazards for outdoor workers and drivers alike.
Know the Risks
- Whiteout Conditions – Strong winds and intense, heavy snowfall result in reduced, or even zero visibility. Drivers may not be able to see more than a ¼ mile ahead in dangerous road conditions—leading to motor vehicle accidents causing property damage, injuries, or fatalities.
- Cold-Related Injuries and Illnesses – Acute exposure to cold stresses can lead to hypothermia, frostbite, or trench foot when the body loses heat rapidly, exposed tissues freeze quickly, or large quantities of melting snow cause outdoor workers to get wet.
Keys to Keep You Safe
-
- Drivers should pull over and use their amber, flashing hazard lights when visibility is poor. If you can’t see, don’t drive!
-
- If you can’t pull over, drive with headlights on—help others to see you.
-
- Stay inside buildings or vehicles to stay warm during snow squalls.
-
- Have a plan in place for dangerous weather events—know where to go, who to contact during an emergency, and access stored emergency supplies.
-
- Keep extra clothing handy in case your clothes become wet or damaged.
