Accidental deployment of a decompression regulator below its safe Maximum Operating Depth (MOD) can have catastrophic results. To help guard against this, Dive Rite has introduced the Second Stage Safety Shield. This simple device consists of a bright green regulator mouthpiece and an elastic strap and plastic D-ring that are held in place with the same tie wrap used to fasten the mouthpiece to the second-stage body.
  
When not in use, the elastic strap blocks the regulator mouthpiece. Thus, were a diver to place this regulator in his or her mouth by accident, he or she would instantly know that something was wrong.
 

 
To deploy the mouthpiece at safe stop depths, divers simply use the D-ring to pull the elastic strap back and out of the way, as shown above.
