When you're waiting it out in the tanker, there's nothing productive you can do, so one may as well take some snaps. Almost all my snaps were taken enroute from one location to another from within the cabin.The few I took outside were when we were taking a quick breather (ie. shoving water and staminade down our throats).That's why we have very few action shots of us at work.EDIT: the crew protection system on the newer tankers is fantastic - basically sprays are located around the outside. You set the pump to minimum pressure and it provides a dripping curtain of water over the whole outside. Our tanker has 3750 L of water, the reserve is 750L (ie 3000L for ff) - we never use that 750L for fire-fighting, it provides about 5min of crew protection (drips not sprays, otherwise the spray would evaporate and not stick to the truck).
