The discharge point shall be a minimum of 25 feet (7620 mm) away from any outside intake, operable window or personnel passage.
The aeration units shall be ventilated through a nonrecirculating dedicated ventilation exhaust system.
When the drain is not located in the ETO sterilizer equipment room, ventilation is required by a capture box.
The ventilation of sterilizer relief valve is required through a pipe connected to the outlet of the relief valve exhausted directly to the out doors at a point high enough to be away from passers by, and not near any windows that open, nor near any air-conditioning or ventilation air intakes.
