The key procedure of passive fire safety in structures is to enclose the workplace with appropriate fire doors, walls, ceilings, and floors. Integrating fire barriers helps in managing fire by interrupting the spread of smoke, toxic gases and fire itself from one fire zone to the next. Fire doors are key to the stability of fire barriers. They act as an accessway to the spread of fire in case these portals are temporarily broken. To minimise such temporary mishaps in protection, fire doors must be self-closing and have a strong latching technique.
