The Dane was required to quickly get out of his car after returning to the pits at the end of his installation lap, with a fuel leak causing the Renault to catch fire. Magnussen was out of the car within five seconds as he jumped out of the front of his cockpit - with the fire at the rear - and suggested the Halo would have slowed his exit beyond an acceptable amount.
"Personally I’ve never run the Halo so I’m not the best person to ask," Magnussen replied when asked if it would have been a different story if he had a Halo fitted to his car. "In my opinion five seconds is too long. If the car is on fire you don’t want to take five seconds. I don't know, it's an interesting question..."
With Magnussen's team radio telling him to get out of the car, he said he reacted to the smoke he saw and was out before the message reached him.
"No, I didn’t know [before the fire started]. Everything worked well on the car on the in lap, so just saw the smoke and hopped out.
"I was already out when they were talking [on the radio]."
However, Magnussen said he had no concerns getting back in the car for FP2, with Renault having an understanding of the likely cause of the fire.
"I kind of knew what caused it when it happened. We had some new parts on the car on the fuel system so…
"It's quite nice to know that the car is not likely to go on fire!"
