The Air Force Research Laboratory Propulsion Directorate, nicknamed the rocket lab, is down to 10 500-pound cylinders of pentaborane, a fuel that ignites spontaneously if exposed to air warmer than 78 degrees Fahrenheit.
The pentaborane cylinders are placed on 2,500-square-foot pads - five cylinders to a pad - at the rocket lab, which is across Rogers Dry Lake east of the main base.
Pentaborane first was produced commercially in the 1950s as a potential aviation fuel.

The Air Force Research Laboratory Propulsion Directorate, nicknamed the rocket lab, has begun burning its stockpile of pentaborane
, a fuel that ignites spontaneously if exposed to air warmer than 78 degrees Fahrenheit.
EDWARDS AIR FORCE BASE - Four 500-pound canisters of a rocket fuel called pentaborane
were disposed of in a controlled burn Thursday at Phillips Laboratory, Air Force officials said.
The bill also includes $2 million for the disposal of 200,000 pounds of pentaborane, a chemical commercially produced in the 1950s as a potential advanced aircraft fuel.
Pentaborane was tested as high energy liquid rocket fuel at Phillips Laboratory, but the fuel never lived up to its potential.
Initial environmental monitoring indicated that the fuel - called pentaborane - burned completely, but extensive analysis will be done before the next six cylinders of fuel are destroyed, he said.
Air Force officials said pentaborane is highly toxic, but when burned produces boric acid and boric oxide, which they called "relatively benign.
