Under what circumstances is it acceptable to chain an exit?

Chaining an exit is strictly prohibited in all circumstances. Exits must always remain accessible and unobstructed to ensure a safe means of egress in emergencies, such as fires or other hazardous situations. The primary purpose of exits is to allow individuals to evacuate a building quickly and safely. Any barrier, such as a chain, compromises this fundamental safety feature, potentially endangering lives in critical situations. This policy is in place to adhere to fire safety codes and regulations, which prioritize immediate access and clear pathways for anyone in a building.

There are no scenarios in fire safety protocols where chaining an exit is acceptable, reinforcing the importance placed on immediate egress access. Other options suggest temporary measures or exceptions for specific situations, but safety regulations universally maintain that exits must always remain open and accessible.
