"That was really bad. They were just running back and I was coming out of the pits. I had to brake and they were very lucky that I avoided them.
"They're normally very good. It's obviously safety, at the end of the day it's most important the safety for the marshals and drivers."
Taking to Twitter to share the video shortly after, the Formula One driver said he hoped he near-miss never happened again.
"After this incident, I'm just very happy with the outcome of my day. That we all can go back home safe and sound with our families. For the safety of the marshals I hope it never happens again!"
Meanwhile, Lewis Hamilton produced a stunning drive, staving off a rampaging Max Verstappen and some destroyed tyres to win his third Monaco Grand Prix in an emotional tribute to Niki Lauda.
Sebastian Vettel was third in his Ferrari and Valtteri Bottas fourth in the other Mercedes but they were elevated to the podium due to a five-second penalty imposed on Verstappen for an unsafe release in earlier pit lane chaos.
