A refrigerated container including a ventilation system, the ventilation system comprising: a leak sensor disposed within an interior space of the refrigerated container and arranged to provide a signal indicative of a concentration of a refrigerant within the interior space; a controller arranged to receive the signal; an injection port; a vent door movably disposed on a floor of the refrigerated container, the vent door being movable between a closed position and an open position; an actuator arranged to facilitate movement of the vent door between the closed position towards the open position; a vent port spaced apart from the injection port, the vent port extending through at least one of the front wall, a rear wall, and a side wall, the vent port separate from an opening receiving the vent door, wherein the vent port is normally in a closed position and acts as a ventilation device or pressure relief device to prevent the refrigerated container from exceeding an internal pressure threshold; a pressure sensor in communication with the controller, the pressure sensor arranged to provide a signal indicative of a pressure within the interior space of the refrigerated container; and a compressor fluidly connected to the injection port, wherein the compressor is arranged to apply an airflow through the injection port and into the interior space to pressurize the refrigerated container with air; wherein the controller is programmed to command the compressor to apply an airflow through the injection port and into the interior space, responsive to the signal indicative of a concentration of a refrigerant being indicative of the concentration of the refrigerant within the interior space being greater than a threshold concentration; and wherein the vent port is controlled to open responsive to the signal provided by the pressure sensor being indicative of a pressure within the interior space being greater than a threshold pressure. a leak sensor disposed within an interior space of the refrigerated container and arranged to provide a signal indicative of a concentration of a refrigerant within the interior space; a controller arranged to receive the signal; an injection port; a vent door movably disposed on a floor of the refrigerated container, the vent door being movable between a closed position and an open position; an actuator arranged to facilitate movement of the vent door between the closed position towards the open position; a vent port spaced apart from the injection port, the vent port extending through at least one of the front wall, a rear wall, and a side wall, the vent port separate from an opening receiving the vent door, wherein the vent port is normally in a closed position and acts as a ventilation device or pressure relief device to prevent the refrigerated container from exceeding an internal pressure threshold; a pressure sensor in communication with the controller, the pressure sensor arranged to provide a signal indicative of a pressure within the interior space of the refrigerated container; and a compressor fluidly connected to the injection port, wherein the compressor is arranged to apply an airflow through the injection port and into the interior space to pressurize the refrigerated container with air; wherein the controller is programmed to command the compressor to apply an airflow through the injection port and into the interior space, responsive to the signal indicative of a concentration of a refrigerant being indicative of the concentration of the refrigerant within the interior space being greater than a threshold concentration; and wherein the vent port is controlled to open responsive to the signal provided by the pressure sensor being indicative of a pressure within the interior space being greater than a threshold pressure.
