I am a fire consultant and I specified that the Elen C1 series, one 80 and one 60 kVA, installed in a room 4 m x 3m x 4.5 m in height, must be installed in accordance with IEC 62040-1. 151 4.5 ah lead-acid batteries are installed. The electrical engineer concluded that ventilation of the room at ceiling level is not required and a internal circulating aircon unit is installed. My understanding of IEC 62040-1 is that the room must be ventilated at ceiling level at a rate of 0.054x151 x 4.5 m3 per hour. This room has literally no ventilation. Plastered brick walls and concrete slab ceiling. The entrance door is a hollow core door and that is all. On entrance a movement sensor at ceiling level switch on a light at ceiling level, neither is flameproof. My question is must the room be ventilated for hydrogen built-up at ceiling level. Attached a plan drawing of the relevant room.
