one of the stumbling blocks to watch out for is liability and onus.

The customer has a high level of responsibility- the service provider has a defined responsibility as does the company who completes the Ex proof conversion.

it should be clear however on who is responsible for the actual equipment supplied. The OEM will have CE marked the equipment (in the EU) and the Exproof converter will then put a CE plate on the equipment.

The act of the Exproof conversion company 'changing' the original specification of the equipment effectively releases the OEM of liability - as the truck no longer conforms to their technical file.

Similarly - the Exproof conversion company should take sole responsibility for the equipment if they are the last to fit a rating plate- this is for the ENTIRE truck.

Any fault in truck design would thus become the responsibility of the company providing the Ex proofing?


Alternatively you potentially sit in the middle of the debacle between the OEM and the converting company both pointing at each other to allocate blame.

NOt a brilliant position to be in when the customer has a contract with you- as service provider- as neither the OEM nor the Converting contractor is under pressure to help resolve the situation
