CVA INCOSE cordially invites you to attend a dinner and presentation by: Mr. David R. Sadler, System Safety Engineer Department of the Navy, Naval Ordnance Safety and Security Activity, Indian Head, Maryland Topic: A General Theory of System Safety This is a joint dinner meeting between the Central Virginia Chapter of INCOSE and the Washington DC Chapter of the International System Safety Society.

Humans through various processes create, store, and move energy from one form or place to another. Le Chatelier's principle asserts that when a system is disturbed that it will seek equilibrium. Energy is therefore not passive in these human processes. When energy finds an unmanaged or insufficiently controlled path to equilibrium, an unplanned release of energy occurs. When such a release has sufficient energy, it produces catastrophic harm. All catastrophic harm or mishaps are the effects of human processes involving or associated with energy save for natural occurrences. A general theory of system safety is that energy is the universal hazard for catastrophic mishaps.
