Safety is the top concern for everyone camping outside of Bristol Motor Speedway this week. There are a few things firefighters say people can do to keep their home away from home free from danger.

There's a constant buzz outside of Joseph Conner's camper -- it's his generator. It's what keeps his RV running, but it's also a source of concern for him. "You can die from carbon monoxide poisoning and not know it. Because you just start getting sleepy," he said.

As it turns out, carbon monoxide poisoning is a top concern for firefighters as well. "It's odorless and colorless, and has no symptoms until it's too late," said Lieutenant Alan Howard with the Bristol, Tennessee Fire Department.

But there's also a problem firefighters see every time race week rolls around. "The campers are parked close to one another and you might hook your generator up and point it away from your camper. But you could be pointing it right into your neighbor's [window]," said Lieutenant Howard.

Which is why firefighters recommend getting a working carbon monoxide detector and testing the batteries.

But campers parked too close to each other is another cause for concern. "If one should have a problem or a fire it can spread very quickly from camper to camper," added Lieutenant Howard.

News 5 learned to get to a fire quickly in tight quarters, Bristol, Tennessee firefighters use a small vehicle armed with fire extinguishers.

A fire extinguisher and a smoke detector are kept close by at Fred Testament's camper. "We put new batteries in like we do at the house and we get all that done. We brought everything but the sink," he said.

Because at the races, it's better to be safe than sorry. "You never know when something might happen, a fire could start," added Testament.

News 5 learned no fires are allowed inside the campgrounds. Fireworks are also banned within the Bristol, Tennessee city limits and campers are reminded to dial 911 if there's an emergency.
