A fan inside of it circulates air, but once in the bomb suit, Millward works quickly, partly because the bomb suit increases its temperature by 10 degrees for every 15 minutes inside.
He also works fast because the threat of a secondary explosion, snipers or rocket-propelled grenades is very real. Millward's team and the RCP continually search for onlookers who may be watching and waiting to explode the bomb, or perhaps those video taping the EOD's techniques to use against them in future attacks.
When Millward works on the bomb, he has no contact with his teammates. Radios could trigger an explosion. It is a solitary experience that can sometimes be scary.
"If you don't know what you're doing then, yes, it is scary," Millward says in an impromptu interview with himself. "Am I nervous? Absolutely. You don't know if it's going to detonate on you on your way down there or not. Ah, do you enjoy being in the bomb suit? Absolutely not. Ah, it's not one of those things where you go, 'Oh Boy, you know, let me get in there.' But it's a necessary evil to make the job happen."
