NEBRASKA -- After the snowfall reached 13 inches in some parts of the state, many Nebraskans will be out on their driveways and sidewalks keeping them clear.

Injuries can happen while scooping snow and it all starts with a few steps.

The cold temperatures already pose a threat to people especially children and the elderly.

The American Heart Association (AHA) says wearing enough layers outside forms insulation and keeps a person warm.

Wearing hats and gloves can also prevent rapidly losing heat from your hands and feet and not allow frostbite.

Without the proper layers of protection, hypothermia can overtake a person’s body before they realize it.

Norfolk Fire Division Assistant Fire Chief Trever O’Brien says staying hydrated is important during the cold.

“Obviously since it’s cold…protect yourself from the cold," O'Brien said. "You’ll be out there working so don’t minimize the thought of dehydration [and] rest frequently as needed. You don’t have to do your driveway or sidewalks all at once if you’re scooping by hand.”

Heart attacks can be another worry and the AHA says to know the signs of a heart attack: chest discomfort, discomfort in other areas of the upper body, and shortness of breath.

The National Safety Council (NSC) says as many as 100 Americans die each year from snow shoveling and thousands more suffer injuries.

Even if there is a lot of snow, the NSC says to take it slow and only shovel if it’s a fresh and powdery snow.

They also say to push the snow instead of lifting it and, when you do lift, make sure to lift with your legs instead of your back.

O’Brien says the department deals with many different types of injuries during the winter season.

“I would say we do see some injuries from snow periodically," O'Brien said. "Big things would be slips, trips, and falls so, obviously, make sure you have a clear path.”
