California Man Falsely Certified O2 Cylinders
Danniel Hoose returned cylinders to use without properly testing them.

Danniel Hoose, owner of Shasta Fire Equipment in Redding, Calif., pleaded guilty in U.S. District Court, Sacramento, Calif., to one count of falsely certifying more than 570 oxygen cylinders for re-use, including re-use in aircraft. In May, a case was filed alleging that in the spring of 2013 Hoose represented that he performed hydrostatic testing on a special permit oxygen cylinder installed in an aircraft, when, in fact no such testing had been completed.
