What is one of the main fire and life safety requirements in building code regarding exits?

The requirement for two means of exit in building codes is a critical aspect of fire and life safety. This is designed to ensure that in the event of an emergency, occupants have multiple pathways to escape, reducing the risk of being trapped. The presence of two exits allows for better accessibility and redundancy, especially in larger or more complex buildings where the likelihood of a single exit being compromised during an emergency is higher.

Additionally, having two exits provides an effective escape route even if one is blocked or inaccessible, which can be crucial during a fire or other emergency situations. It is a standard principle of building design to prioritize occupant safety by allowing for quick and safe egress from a structure, making this requirement vital in various building types, including residential, commercial, and assembly occupancies.
