Explosion Proof Circuit Breaker Panel at a Gas Station

[hyprfrco]

Check the attached photo of a gasoline station.

The two panel boxes at the center of the photo (in the corner of the station) are standard panels (IP-67), which enclose standard circuit breakers for the main gas pumps of the station.

They are less than 7 linear meters on separation.

I would like to ask you, if you have experience on electrical EX-proof facilities:

Is there any mistake here? Or is everything right according to the EX-proof codes?

Under the Canadian Electrical Code the separation must be 4.5 meters. An inspector may require the length of the hose plus 4.5 Meters radius.
