To get all the nets successfully routed out of a BGA can end up being a great escape in its own rights. SOLAS Regulation II-2/13.7.4 Means of escape currently requires escape routes on ro-ro passenger ships to be evaluated by an evacuation analysis early in the design process, and recommends the use of MSC.1/Circ.1238 when conducting the analysis. The economic repercussion of this is overwhelming as well. However, many OSHA guidance materials strongly advocate the use of such maps or floor plans, some to the degree of specifying it as a requirement.

The group of patients with disabilities who used canes (2), moving by their own force, showed the maximum RSET value under the evacuation condition using stairs, and this was found to be the most inefficient evacuation method. The reason why FED was set to 0.3 is that it has been reported that evacuees are incapacitated from the FED value of 0.3 because of the decrease in oxygen due to the inhalation of carbon monoxide and carbon dioxide and insufficient oxygen caused by fire. 2022; 14(10):5998.
