Yeah there was, they have burn over protection in case they get overrun by fire, this one from South Australia for example has a few features:

Key features standard across all response vehicles:

• Cabin deluge systems for cabin glass protection.
• In-cabin breathing systems for crew oxygen supply for burn over events.
• Cabin crew protection (window curtains, where required) as radiant heat shields.
• In-cabin pump control to enable operation of Cabin Deluge from the cab.
• Under-cabin heat shields to reduce radiant heat penetration of cabin structures.
• Tyre spray systems to reduce radiant heat.
• Updated visibility markers to new safety standards to improve fleet visibility on fire grounds and when responding.
