What should you do if one oxygen tank has two washers in the hanger yoke connection while another only has one?

The appropriate action is to eliminate the extra washer from the tank that has two in the hanger yoke connection. Each oxygen tank is designed to operate safely and effectively with a specific configuration of washers. The primary role of these washers is to create a secure seal that ensures no oxygen leaks occur.

Having a different number of washers on each connection can lead to improper sealing and potentially dangerous leaks, as the seal may not function correctly if mismatched. By standardizing the number of washers used – in this case, ensuring that there is just one washer per connection – the risk of leaks is mitigated, enhancing safety during oxygen use and preventing any operational discrepancies between the tanks.
