Does anyone have any idea what this writing is on a UKF Tank?

[Esmedune]

Hello all,

I am struggling with this line of white on black writing at the bottom of this tank. I have purchased a couple of images from Paul Bartlett, and he has also been kind enough to check all his other images, and he cannot make it out either.

 

 

These are from a 35mm slide scanned at 9600dpi, but I still can't even begin to have a guess.  Has anyone been up close and personal with one, that could tell me what it says?  I am building a transfer set for it and this one has stopped me dead in my tracks..

Thanks

Found this site. One of the tank writings reads: 'No Naked Light'. May be worth contacting their customer support? They might be able to answer your question.

…looks like maintenance dates/schedule to me, have a look at images of other STS tanks of the period to compare.

NOT TO BE LOOSE OR HUMP SHUNTED

It says "Don't spill this on your skin or else you'll smell like stale piss for weeks"

A lot of tanks were just marked 'Not to be loose shunted' as opposed to 'loose or hump shunted'

Looks more like that than anything else. Plenty of wagon images at  https://www.flickr.com/photos/hmillington/2034966881/in/album-72157603195747980/  but only found three of Ammonia tanks on page 12....

The text on petrol tank wagons say (more or less):

 

No naked light
to be brought near tank
Keep cover securely fastened
whether loaded or not
Max working pressure 10 psi

 

I would guess this is the same type of information - basically safety instructions. Ammonia is not flammable, but safety data sheets do say keep sources of ignition away, so may well be there. The maximum pressure will be well over 100 psi, and looks to be the second line of text? The other lines look like they start "no" to me.
