Gents, Can we allow normal laptops to use in zone 2 hazardous areas, I will have a vendor comes to the site to upload some software informations to the Main valves of Natural Gas, the area is under Zone 2 classification. Can anyone plaese advise me whether there is any laptop's intrinsically safe skins/cover to use on normal laptops to use them in hazardous classified areas, if so please pass me the details?

I would say yes you can, under a hot work permit and all the usual controls.

Once you have classified and demarcated "zones", it is not good practice to bring in ordinary equipment that has the potentail to be a source of ignition. You should have robust procedures by means of permit to work systems if you need to introduce non-intrinsically safe equipment. The ignition risk from a laptop is lilkely to be very low, but I am not an electronics/electrical expert. If you can hermetically seal laptop with a plastic cover, even if there was a spark, it would not ignite the gas should there be an accidental release and at the same time be at the explosive limit level--the probability is very low.

As I recall zone 2 is the least hazardous and is the same status applied to the retail shop part of a petrol forecourt (at the pumps zone 1 and tanks and pipes carrying petrol zone 0) Computers are used in the shop along with other electrical equipment , cash registers ect which dont need to meet the requirements of BASEEFA
