- A firewall is a partition structure that normally consists of two side walls with a fire retardant material between them. - A firewall does not prevent a fire. - A firewall does not extinguish a fire. - A firewall only delays the propagation of a fire event to the other side. - The characteristics and properties of each side are independent and not necessary equal. - A firewall eventually gets on fire. - Fire retardant performance is dependent on type of fire and subject to change without notice. - A firewall does not prevent against monkeys with matchboxes. - In the event of a fire locate the nearest exit. - Use the exit and wait in a safe place for the arrival of trained personnel to extinguish the fire. - Clean up the mess and get rid of the monkey. - Apply to computer networks as necessary.
