1. 5-6-4/13.3 Pump Room Ventilation
Recovered oil pump rooms are to have a mechanical ventilating system capable of providing at least twenty air changes per hour based on the gross volume of the space. The system is to have a mechanical exhaust, natural or mechanical supply, and ducting as required to effectively purge all areas of the space. Fan motors are to be located outside the space and outside the ventilation ducts.
这里提到的Fan motors are to be located outside the space and outside the ventilation ducts，有点不理解。风机的电机总是要装在风管的末端吧，难道这也算outside the ventilation ducts?
2. 5-6-4/13.9 Ventilation Alarms
The alarms to indicate failure of the mechanical ventilation as required by 5-6-4/11.1iii) and 5-6-4/11.3iii) are to provide audible and visual signals at the designated normally manned station. The initiation of these alarms by a fan motor running or fan rotation monitoring device is not acceptable.
这里提到的失效报警，是不允许通过测定电机的运行来实现的，后面的规定提到了The alarms to indicate loss of ventilation overpressure as required by 5-6-4/11.5iii) are to be set to a minimum overpressure of 25 Pa (0.25 mbar) with respect to the adjacent Zone 1 location. 这里是否有什么测气压的压差计，灵敏度能达到25Pa的？
