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.

The film

Page by page

A vertical film from our own bench — this page contacts nobody's server to play it, and downloads nothing until you press play.

A vertical film, 52 seconds: the cover, the ruling page, then 5 reference pages. Synthesised ambient bed, no dialogue — captions in three languages.

Real pages

Five pages from the Boiler Operation Log laid out as cards: a six-column log page, a section divider, a college-ruled notes page, a conversion table, and the pen test page.
Five pages rendered straight from the print file: the six-column log, a section divider, the lined notes pages, the conversion tables, and the pen test leaf at the back. The columns are the product. A boiler reading with no initials against it answers to nobody, and fixing that is the reason to buy one rather than rule your own.

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.
Michael Faraday, The Chemical History of a Candle, 1861
