walls etc. that can resist fire Explanation: Fire barriers (walls etc. that can resist fire) are rated by how long they can resist a "standard" fire. So you can have a 1 hour, 2 hour, etc. fire barrier. Your text is saying that where there are sprinklers, the required quality of the fire barrier can be reduced by one hour. For example, if a 5 hour barrier is initially required, adding sprinklers reduces that requirement to a 4 hour barrier. |
