i have never seen a hazardous area in a bakery. the flour dust is only a problem in larger quantities,such as a silo.

dave just to cover yourself...write a letter/email to the customer requesting information of any classified areas...he must respond with details of any classified areas if any...if he response and tells you there are no classified areas you can go ahead with a standard coc.
it is not your responsibility to classfiy areas...it is the customers responsibity to inform you of any areas which are classified.
if you are concerned...let me know and we will quote you to assess the installation...but if i were you i would get the customer do it...its not cheap.
always be careful of this...there are lots of different factors which must be taken into consideration for classified areas...gasses...suspened dust...battery charging rooms...spray booths...etc...etc
some big factories have thier own refuel points...so to cover yourself when working in big factory/warehouse enviroments always check and make sure...this would break the bank if you get caught off guard.
always CYA.

i think if i tried it...i would get caught out because if the judge was smart he would tell me but you should have known better...being a master electrician...but in your case so long as your inspector is only an installation electrician he could say but how was i suppose to know and by gettin the customer to give it to you in writting you would have taken precaution...which will count in your favour.
the other thing you need to watch out for are flamable signs located in various locations...but it would still go back to the customer why didnt he notify you.
I think the obvious stuff remains obvious. For example, if we did a panel beaters shop and signed off on the spray booth, I think we'd still be in for the high jump even if the owner signed off as there being no classified areas.

Spray areas would be either zone1 or zone2
Bakery flour would be considered a class I dust
class I – dusts that ignite and propagate flame readily; the source of heat required for ignition being
small (in the case of an electric spark, 40 mJ being a normal value);
