Abstract: High pressure compressed gas pressure vessels and devices utilizing such vessels are disclosed herein. More particularly, aspects of the present invention are directed to high pressure (i.e., nitrogen or N2 based) pressurized gas cylinders with pierceable membranes recessed from the opening of the pressure vessel such that prior art piercing mechanisms cannot pierce the membrane for safety purposes. Additionally, aspects of the present invention are directed to pressurized gas operated devices with elongated pins for piercing pressure vessels with recessed pierceable membranes.
