Ventilation is crucial in tunnels to control smoke during a fire, allowing for occupant egress and providing access for emergency services. The standard provides formulas and criteria for: outlining the testing and commissioning checklists

Fiber-optic linear heat detection cables along the tunnel ceiling.

While historical configurations relied purely on ventilation, modern versions of the standard outline fixed water-based suppression. Systems using deluge water spray or water mist can reduce a heavy goods vehicle (HGV) fire's peak heat release rate (FHRR) by , creating tenable conditions for evacuees and emergency personnel. 4.
