Update

• Should the MPS Acceptance Criteria be changed to address the issue of agents enhancing the propane explosion at subinert concentrations?

or

• Should we just rely on the MPS statement that says that “the performance of the replacement agent and system [must] provide the same level of safety as the currently used Halon 1301 system”?
