Sixty pages, six columns to a page: date, time, pressure, feedwater, blowdown, initials. A pressure reading with no initials against it is a number nobody can stand behind six months later, when an inspector asks who was on shift.
After the log come twenty-nine pages ruled college, twenty-four lines a page, holding what a column cannot: why a blowdown ran long, what the water treatment contractor said about a foaming trip, who signed the boiler back on after it.
It does not print your operating pressure or your blowdown interval. Those are set by the boiler code you are licensed under and the insurer covering the vessel, and they differ by jurisdiction and by boiler. The book gives you somewhere to write the reading down, not the number to write.

In every book
The same six pages open every book: your details, who to call, the signs to point at when you have no shared language, and the map. They sit at the front because the moment you need them is not the moment to be flicking through.
- How to use it
- One page describing this book, not a different one.
- This book belongs to
- One page for your name and number, so a book that goes missing can come back.
- My details
- Blood group, allergies, who to call. Written once, carried everywhere.
- Emergency numbers
- Forty countries, taken from Wikidata property P2852 (CC0), agreed across two sources, every row carrying its QID. Numbers change and a book does not — verify locally on arrival.
- Point at this
- A pictogram grid captioned in English above and Indonesian below, for when there is no shared language.
- World map
- Natural Earth 110m, public domain, equirectangular, with UTC hour meridians computed from the projection rather than from a timezone database. For orientation and for pointing at, not a navigation chart.
- Conversion tables
- Computed from definitions — 25.4 mm to the inch — and not copied from anywhere, so every row can be checked by anyone holding the book.
- Pen test leaf
- The last page, printed for it on purpose. Every notebook is used this way; printing it deliberately is cheaper than losing the last leaf to it by accident.

Questions
What are the six columns?
Date, time, pressure, feedwater, blowdown, initials.
How big is it?
A5, 148 x 210 mm, 100 pages, 5.72 mm across the spine.
Is it dated?
No. Start it on the first shift you log.
Does it print my operating pressure or blowdown interval?
No, and that is deliberate. Those figures come from the boiler code and the insurer covering the vessel, they differ by jurisdiction, and a printed book cannot be corrected. The columns give you a place to record yours.
What ruling are the notes pages?
College, 7.14 mm, twenty-four lines to an A5 page.
Who initials the log?
Whoever was on shift when the reading was taken. The column exists so that question has an answer.
As long as we supply oxygen, so long can we carry on the combustion of the iron, until the latter is consumed.
