Life Safety Code and HC refrigerants

As a healthcare organization we are concerned about the transition to flammable HC refrigerants in refrigeration as mandated by the EPA.  These new units come with a risk of fire or explosion label and NFPA101-2012 appears to indicate that explosion potential moves these items into a high hazard category requiring additional protective consideration.  I can see where the NFPA has acknowledged the additional hazard presented by these SNAP refrigerants through holding at least one workshop to reconcile the hazards presented to first responders but I cannot find any direction in relation to life safety code considerations.  We are at the tipping point where the non-flammable (explosive) options are becoming few and expensive but we don't want to be caught in a position where we are introducing an unreasonable or difficult/expensive to mediate hazard into an environment where the reduction of hazards has been a primary driver.  Any help resolving this will be appreciated.
