The snow may be melting, but with homes and traffic signals without power, plenty of hazards remain both inside and outside your home.

Generators can get the lights back on, but they can also produce deadly fumes.

"The main safety tip is just to make sure that you keep them outside, that you don't have fumes and everything," said Ann Matlack of Vera Cruz, Lehigh County.

"Keep it at least 10 feet away from your house, from any openings," added Capt. Thomas Carl with the Allentown Fire Department.

Carl said, don't even think about bringing charcoal or gas grills inside for heat.  The coroner said one man in Emmaus died after apparently using a charcoal grill to heat his home.  He was likely overcome by carbon monoxide fumes.

"Those [items] are designed to be used outside, not inside," said Carl.

If you've got a fireplace, make sure you have a professional chimney sweep check for obstructions.  That can also trap deadly carbon monoxide in your house.

"A lot of times the leaves will fall and block up the chimneys, so you want to make sure the chimneys are clean and free of leaves and debris," said Robert Burkholder of Burkholder Heating and Air Conditioning in Emmaus.

Carbon monoxide is often called "the silent killer" because it has no taste or smell.  The best defense is having several battery-powered CO detectors.

"You want them outside of all the bedrooms, and located outside the garages," said Burkholder.

There are warning signs of carbon monoxide in your house.  According to UGI, those signs include condensation on walls and windows, house plants dying, pets becoming sluggish, and especially odors from a malfunctioning appliance.  Even a small amount of CO exposure can lead to flu-like symptoms and nausea.

Dangers exist away from your home too. 

Hundreds of traffic signals are still out.  Drivers who don't stop aren't just inconsiderate; they're also breaking the law.

"A rolling stop, they just go through," said Bryan Gruver of Emmaus.

Any traffic light that's out is considered a four-way stop.

"Most people are stopping and waiting and taking turns and letting people go," said Matlack.

The hazards don't end there.  Fire officials say to stay at least 20 feet away from any downed line.

"Even though it would appear there's no electricity going to it, at any time that power could come back on," said Carl.

And then there are all those trees in the road.

"It really looks more like a hurricane came through with all the trees down," said Linda Stothart of Shimerville, Lehigh County.

Carl added that you should stay at least  the distance between two telephone poles away from downed trees.

Most drivers are staying cool and following the rules.  Brian Gruver had one word for those who aren't.

"They're just arrogant, is the nicest way, because you won't want to put [anything worse] on the news."

A lot of this is common sense, obviously, and police report relatively few accidents despite of all the non-working lights and the debris.
