Fire door

A fire door is a <a href="/facts/Door/ts2uMoVm">door</a> with a <a href="/facts/Fire-resistance_rating/JRm45fk8">fire-resistance rating</a> (sometimes referred to as a fire protection rating for closures) used as part of a <a href="/facts/Passive_fire_protection/D0WVYQzU">passive fire protection</a> system to reduce the spread of <a href="/facts/Fire/M6XwR3am">fire</a> and <a href="/facts/Smoke/KRJaumoC">smoke</a> between separate <a href="/facts/Compartmentalization_(fire_protection)/jy3Po08c">compartments</a> of a structure and to enable safe egress from a <a href="/facts/Building/edSjKXje">building</a> or structure or ship. 
In <a href="/facts/North_America/djNjCQIl">North American</a> <a href="/facts/Building_code/CXCHd3IC">building codes</a>, a fire door, along with <a href="/facts/Fire_damper/yoClN9pt">fire dampers</a>, is often referred to as a closure, which can be derated compared against the fire separation that contains it, provided that this barrier is not a <a href="/facts/Firewall_(construction)/G5fK74YR">firewall</a> or an occupancy separation. In Europe, national standards for fire doors have been harmonised with the introduction of the new standard <a href="/facts/EN_16034/wkLqEPur">EN 16034</a>, which refers to fire doors as fire-resisting door sets. Starting September 2016, a common <a href="/facts/CE_marking/F13U8QXp">CE marking</a> procedure was available abolishing trade barriers within the <a href="/facts/European_Union/6GYcR8qM">European Union</a> for these types of products. 
In the UK, it is Part B of the Building Regulations that sets out the minimum requirements for the fire protection that must be implemented in all dwellings this includes the use of fire doors. All fire doors must be installed with the appropriate fire resistant fittings, such as the frame and door hardware, for it to fully comply with any fire regulations. The British Woodworking Federation outlines the difference between a 'Fire Doorset' and a 'Fire Door Assembly'.
