What is the normal working limit for air on the KM37?

The normal working limit for air on the KM-37 Portable Surface Supplied Diving System is 190 FSW (Feet of Water). This limit is established based on the physiological effects of pressure on the human body and the capabilities of the diving equipment.

At depths greater than 190 FSW, the risks associated with breathing air, such as nitrogen narcosis and oxygen toxicity, significantly increase. The KM-37 system is designed to operate safely within this limit, ensuring that divers can work effectively and minimize health risks while performing their tasks underwater. Understanding this limit is crucial for maintaining diver safety and ensuring that operations are conducted within safe parameters.
