Last nights explosion near Savannah serves as a reminder of just how dangerous industrial properties can be. Charleston County is home to many properties considered to have hazardous materials on site. Manufacturers like Rhodia, a chemical plant, take safety very seriously. In Charleston County alone several industrial sites are so close to neighborhoods and other populated areas, the companies often work with the communities to make sure everyone knows what to do when something goes wrong.

Waste facilities, chemical plants and gas companies are scattered all throughout the Lowcountry. Though the risks they present, you may never know, unless an accident happens.

"The County at large is at threat for anything. Especially with some of our industry because you never know what conditions are going to be when something happens," said Kathy Haynes, the Charleston County Emergency Services Director.

Which is why County, City and all local agencies train together.

Haynes says most large events can't be handled by just one organization. In order to keep better track of which companies could put others at risk, all businesses that use or store any chemicals that if accidentally released could pose a threat, are required to report their materials. In Charleston County alone, there are 257.

"One of the things you have to do is figure out what's on fire," said Chief Franklin Finley, who leads the Hazmat team within the Charleston City Fire Department.

Chief Finley leads the City's Hazmat team. He says his men do drills and walk throughs at dangerous locations, but at the time of an incident, they rely on paperwork at the site to point them in the right direction.

"The industries are required by a county ordinance to have this box. It's weather and disaster proof at the entrance of all facilities and in that box is their sight safety plan which lays everything out on site, " said Haynes.
