I don’t see how you can NOT comply with all requirements assigned to ESFR sprinklers. They are a suppression mode sprinkler with a smaller remote area so must knock down the fire quickly. Obstructions are a huge issue. It’s not really a content driven thing since Class I commodities have a similar density demand to OHG1 and it still has to comply with the same obstruction rules. Granted the difference it fire growth rate and HRR will impact the issue but most likely it will be in how quickly the system FAILS and not whether the system will fail.
