Required Safe Egress Time RSET and Available Safe Egress Time ASET can be used to determine the life safety in building. Larger hoses reduce friction and therefore increase conductance speed. Total Evacuation Time TET was highly concerned. From 730am to 615am is 22 hours and 45 minutes. How much time do manufactures suggest for proper system evacuation.

However the hand calculation method has been found to be unsuitable in certain applications for example buildings with specific seating arrangements different occupant groups etc.

It is important to note that since contami-nant density of a system is greatest dur-ing. After a hold time of ten to fifteen minutes at 300 microns the system is considered successfully evacuated. Inside a system at any given time all play a critical role here. Yet its a process most manufacturersespecially those manufacturing. This calculation can be concise for a simple geometry but lengthy for complex buildings. The physics of evacuation are quite different from charging and pressure testing.
