Personally I seldom enter refineries, because they want to take my cigarette lighter off me at the gate. Surprised I don't have to take off my polyester jacket in case it build up static. Kind of scary to think (the absence of) a cigarette lighter is the only thing between safety and oblivion.

Re the laser thing, from memory there is a minimum current/voltage threshold below which you are OK (to do with ignition energy) so it would pay to check before giving up.

Cheers

I've seen this type of resrictive policy in refineries as well. Mostly it is overkill for visitors.

Often, within secure facilities, the regulars have fun with visitors that are unfamiliar with regulations.
