Your equipment will probably need compliance with the ATEX directive. I do not have much experience with it but what I know is that equipment (wires/ sensors) above a certain (very low) power level need to be enclosed securely with an auto expanding enclosure, enabling a safe release of high pressure gases possibly caused by an internal explosion. The route gases flow to leave the enclosure needs to be long, in such a way their temperature lowers below the calculated ignition point of the environment. To enable electricity to leave such an enclosure, special cables are required, or the power level needs to be reduced to a safe level using redundant parts (f.a. several resistors, several diodes (blocking), etc.
Others may have different opinion or might add to this. I am not saying it's all accurate I was writing above. It's what I picked up from customers needing EMC tests for their equipment.
