The construction of a “H” rated fire door

Hydrocarbon fire, or pool fire, is a fire fuelled by hydrocarbon compounds (oil and gas), having a high flame temperature of 1000°C (1832°F) within 5 minutes and 1100°C (2012°F) after 5 minutes, achieved almost instantaneously after ignition. This fire is more intense, fierce and spreads much more rapidly than cellulosic fire. “H” rated doors need to withstand a much more extreme form of fire in comparison to “A” rated doors.
