Are these a substitute for the operating manual?

No. They explain how things work and why, and they cover the judgement that manuals leave out. Your plant's own manual, your PESO licence conditions and your written procedures are what govern operation.

How often are guides updated?

Each carries a last-reviewed date on the page. Technical content is revisited when a standard changes, when our own operating experience contradicts it, or when a reader tells us it is wrong.

Guides

Know-how from people who run the equipment

Q: Who writes these guides?

People who operate the equipment, not a marketing agency. Every guide carries a named author and a last-reviewed date, and the technical content is reviewed by a member of the BIS gas cylinders committee. See our editorial policy.

Q: Can I ask for a guide on a specific topic?

Yes, and it is the best way for us to choose what to write next. If a question comes up often enough that you are searching for it, it is worth a page. Tell us what you could not find an answer to.

Practical guidance on operating acetylene plants, handling cylinders and choosing grades — written from operating experience rather than from a brochure, with a named author and a review date on every page.

Not a substitute for the manual

These explain how equipment behaves and why, and cover the judgement a manual leaves out. Your plant's own manual, your PESO licence conditions and your written procedures are what govern operation.
