As I'm primarily an engines man (although I'm in the middle of a "cross dressing" course to become a rigger as well. Good ol' RAF. Back to the way it was done 15 years ago!), I always sanitize the area around intakes before starting engines. Mainly because it's me that has to change the bloody engine if it gets FODded.......
Last incident we had was a strap securing bolt on a ground-running guard broke, and got sucked down the intake, necessitating an engine change.
