A massive fire broke out Saturday afternoon at a laboratory building on the University of South Florida campus in St. Petersburg, authorities said.

Campus police said fire crews were called to the Marine Science Laboratory building for a structure fire.

No injuries have been reported, and the building was safely evacuated, police said.

The cause of the fire is under investigation.

Large plumes of gray smoke were seen rising from the building late Saturday.

According to the Tampa Bay Times, students and staff were alerted to the fire shortly before 6 p.m.

The school sent an alert reading: “Urgent Alert. Fire reported in MSL, Marine Science Lab. Evacuate building. Avoid area. Emergency personnel responding.”

St. Petersburg Fire Chief Michael Lewis said more than 60 units and about 200 firefighters responded to the scene.

Lewis said around 9 p.m. that the fire was largely extinguished but that the building is likely “a total loss.”

“The entire roof has burned off,” he said, according to the report.

USF police said it will provide additional updates as more information becomes available.

Sometimes we forget how hard it is to be a cameraman. You’ve got to focus on what you’re supposed to be shooting and block out all other distractions.

Of course, sometimes a little eye candy comes along and slips through the goalie, and that’s what happened to one cameraman — and you’ll see in a second why I’m fairly certain it was a cameraman — working in the Formula 1 Miami Grand Prix paddock.

Hey, he’s only human.

After Friday’s Sprint Qualifying session, UK broadcaster Sky Sports was doing some analysis with 2009 World Champion Jenson Button, former driver Naomi Schiff and presenter Simon Lazenby.

However, their coverage was somewhat interrupted when the cameraman got a little distracted by a certain paddock guest.

I bet a couple of husbands got dirty looks from the missus when they yelled, “Hey, that’s Ivana Knoll!”

That’s right, internet sleuths were quick to identify the 2018 World Cup’s “sexiest fan.”

Which is a heck of a title. Do you realize how many people were at that?!

The cameraman managed to get back on track, although it was probably good that one McLaren mechanic wasn’t handling any power tools when Knoll walked by.

That could’ve been disastrous.

I do think Knoll knew what she was doing. One does not stumble into the title of “sexiest fan.”

That’s not the kind of outfit you usually see in a busy paddock with tools and pieces of cars and big stacks of tires all over the place. But Knoll knew there would be cameras, and dammit, where there’s sports and cameras, there’s “World Cup sexiest fan” Ivana Knoll.

Maybe she’ll get a little more facetime at Sunday’s Grand Prix. It was announced on Saturday night that the race’s start time has been moved up three hours to 1 p.m. ET, in an attempt to avoid inclement weather later in the day.
