Standard EN 60079-10, as area 1 (place where it is possible, during normal operation, that an explo
forms due to the presence of gas).
According to Standard EN 50272-3, distance d for drive batteries is equal to 0.5m.
The distance varies depending on the battery features and, therefore, in the presence of more types of batteries, it
must be identified for each of them.
According to Standard EN50272-2, distance d for stationary batteries is identified by the following formula:
With natural and/or artificial ventilation with adequate availability, we can consider, for the purposes of safety,
providing around area 1, a boundary area 2.
