Torrey DeVitto has been working in a "whole new world" since the coronavirus lockdown was eased

Torrey - who plays Dr. Natalie Manning on the show - shared: "It’s been really interesting. For everyone in the world right now, it’s a whole new world, but working under these conditions is really interesting because there are so many protocols in place.

"It was really mind-blowing for me, how well NBC kind of took control of the situation and how much they’re spending just on keeping us safe alone."

The actress revealed that the show's cast comes to set early to be tested five days a week.

The stars of the show are also only permitted to remove their masks when they're filming.

Speaking to Us Weekly, Torrey explained: "We’re only allowed to have our masks off for 10 minutes at a time, so once we take our masks off during shooting, a timer goes off, and we have to do 10 minutes on the dot.

"It’s just very intense. I kind of have to take a moment to remember - and I have to ask [questions] as well because my mind gets so caught up in all these protocols!"

Despite the safety measures, Torrey still felt anxious about having to return to work.

She said: "I have been so mindful and so careful, and I feel it’s been mostly because I’m worried about catching it for other people.

"Obviously, I don’t want to get sick myself, but there’s this element where you think more about protecting the people around you. So, that grew exponentially when I started working because jobs are so few and far between right now. We’re all so grateful to be back at work and to be working and to have a job again.

"So, for me, I was like, I don’t want to be that person that messes it up for everybody. I can’t be."
