Bill,
It does not mean no aisle jump. In the tests that Class I-IV protection
are based on, a test was considered successful even if ignition occurred
across the aisle but was contained (did not burn through to the other
side) of the target rack.

What is the minimum aisle width in order to use the ceiling only
densities for miscellaneous rack storage (Chap 13 - 2007)? Aisle widths
are specified in Chapter 16 but not in Chapter 13. Would this width be
3.5 ft per 3.9.3.7.5?
I'm assuming this would mean there's no ignition across a 3.5 ft aisle
if Table 13.2.1 is applied.
