Wet riser inlet

While I’m on the subject of One Blackfriars, as I was last night, here is a rather charming piece of urban sculpture to be seen outside its front door, photoed earlier on the day I photoed the photo in the previous posting:

I’ve heard this expression but never understood what it was about. Having read this, I now understand it a bit better:

Wet risers are used to supply water within buildings for firefighting purposes. The provision of a built-in water distribution system means that firefighters do not need to create their own distribution system in order to fight a fire and avoids the breaching of fire compartments by running hose lines between them.

Wet risers are permanently charged with water. This is as opposed to dry risers which do not contain water when they are not being used, but are charged with water by fire service pumping appliances when necessary.

Part B of the building regulations (Fire Safety) requires that fire mains are provided in all buildings that are more than 18 m tall. In buildings less than 50 m tall, either a wet riser or dry riser fire main can be provided. However, where a building extends to more than 50 m above the rescue service vehicle accesslevel, wet risers are necessary as the pumping pressure required to charge the riser is higher than can be provided by a fire service appliance, and to ensure an immediate supply of water is available at high level.

NFL photoer photos The City Cluster (plus video of a stadium roof opening)

I do like an interesting hat, when I photo a photoer:

And I admire this photoer’s choice of subject matter. The Scalpel was looking especially fine, its angle catching what was left of the setting sunlight. We’re at the top of the Tate Modern Extension, by the way. A favourite spot of mine.

But, going back to that hat. What does it say on it? P……..S? Philadelphia Eagles? Pittsburgh Steelers? A bit long, but conceivably one of those.

Hang on, I wonder if I photoed any more photos of that same photoer, which might shed light on the matter.

Yes:

I hope a robot couldn’t identify this guy from that photo, what with it being so blurry, although I dare say his loved ones could. But, anyway, what that says is that the hat goes P….OTS. And we have our answer. He is a supporter of the New England Patriots.

And no wonder he is proud to be sporting this celebratory headgear. The Patriots are due to contest Super Bowl “LIII” (53), against the Los Angeles Rams, this coming Sunday, which I will be watching on my TV. Here is a Daily Telegraph report about that.

The game will be played in Atlanta’s Mercedes Benz Stadium, of which, the Telegraph says:

That jagged-looking roof opens and closes in a very pleasing way:

The “:” is there because there then follows video of this pleasing effect (that being it on YouTube). I greatly enjoyed this.
