mobile ventilation unit

can't say that i've ever seen one of these before until one rolled next to me on the outbound edens this a.m.

what, pray tell, is this vehicle? none other than a firefighting mobile ventilation unit. the wide world of info online tells me that......

The MVU works by creating an air-seal at the entrance point, pressurizing the structure. The resulting airflow blows clean, fresh air into the structure, forcing out heat, smoke, gasses and other contaminates. It can be used to ventilate any size or shape structure as long as there is an entrance point for the clean air and an exit point for the contaminated air. It is a proven technique that saves lives, and improves worker and citizen safety.

Places the MVU is at work:
Large Frame Aircraft
Hotels
Chemical Plants(747-400, A-340, A-380)
Tunnels
HazMat Spills
Passenger Terminals
Terrorist Threats
Large Factories
Aircraft Hangars
High Rise Buildings
Open Malls
Freight Warehouse Facilities
Atrium Lobbies
Ship Ventilation

learn something new each day and keep the mind sharp.

i also spied a gleaming white herse en route to the boneyahd with a screaming orange siren on top, followed by two matching white limos. quite a chilly day to bury a loved one.
