Whether transporting fuel for a Jet Ski or fueling a boat for lobster mini-season, officials are asking residents to keep in mind several safety elements.
Here in the Keys, it is typical to see gas cans in the beds of trucks for the purpose of fueling ocean vessels and vehicles.
However, there are strict guidelines for transporting fuel that is not in the tank of a vehicle.
A 25-gallon maximum -- up to five, five-gallon containers -- can be carried together unless licensed otherwise. The containers must also have proper ventilation and an official placard labeling it.
"The key is to haul fuel in the proper container," said Fire Marshal Danny Blanco. "Fuel should be carried in DOT-certified containers with proper ventilation because vapor is the most ignitable ... vapor ignites before liquid."
Even when following all the restrictions listed, transporting fuel is still a dangerous task, said Blanco. It is important to take fuel straight to its destination because heat can cause fumes to ignite.
"Some may not be aware of the allowed container size," said city spokeswoman Alyson Crean. "This is an ongoing thing, people with smaller vessels and Jet Skis have a tendency to haul their fuel in vehicles."
There have been some complaints so there is heightened awareness. The police department is keeping an eye out to ensure safety with fuel transportation and storage because of how hot it has been, said Crean.
With temperatures hovering in the low 90s and the heat index soaring into 100 degrees this week throughout the Keys, according to the National Weather Service, temperature is a real concern.
"Every couple of years we have the same issue," Blanco said. "Hopefully, once the word gets out, people will do the right thing and follow these guidelines."
