Dry Break Couplings are specially designed with an interlock feature in each coupler, this feature prevents the fitting from being opened until securely attached to the adaptor. Once the dry break coupling has opened the coupler cannot be removed until the valve is completely closed. This design means you can eliminate the risk of nasty spills and prevents endangerment to personnel and the environment.
