Stream of thoughts:
Is in a storage application does the storage itself create areas where the
water can't reach because it hits things that are not on fire. Just like FF
can't use monitor nozzles at the doors most times.
In a large venue many times the throw is to get over seats for example. The
target area, sports floor, is relatively small compared to the space around.
Also, typical fire hazards in an arena are low in height compared to storage
up to the joists. You can sometimes lob the water over because you have
clear space over what's not burning. But not in a typical storage occupancy.
Ever heard whining about the 3' with sprinklers.
Certainly it's viable depending on what the performance objectives are.
Accept you will lose the building and some protection that fails is better.
Just kidding.
Either way sprinklers or cannons you are just as screwed in a failure of any
kind. No testing to support it will control the fire.
Another concern is the blast from the cannon breaking up whatever is burning
into several chunks of burning stuff. Think aerosols rocketing about. I've
pushed down walls with master streams. Granted they were weakened from fire
to start.
I'd certainly love to see the fire testing this was put through, the China
version. Easily I can see combining CCTV fire detection and current
robotics and current auto-oscillating nozzles used in hangers. But together
does it actually put out the fire.
Like all good ideas and this may very well be the only things slowing it
down is money.

Subject: Automated Water Cannons for Use in Storage Applications and
LargeOpen Areas
Has anyone ever heard of automated water cannons being used for fire
protection in the US? This technology is being employed in China and was
mentioned in a recent article in NFPA magazine about the new Beijing Olympic
stadium and swimming venue. It sounds like basically a remote controlled
monitor that can throw water up to 200 feet which is actuated and controlled
using a vision system that can detect fires. They apparently use them
frequently in large open-space applications. This sounds like an excellent
application for the dry storage of boats possibly and other storage
configurations. Imagine having three or for of these monitors in a
warehouse or marine with some cameras to cover everything. Then upon
detecting a fire, it could feed live video to the monitoring station and
even turn itself off automatically after visually confirming the fire was
out.
Just kicking around an idea. Any thoughts?
