HAZOP worksheet Excel template.
A HAZOP (hazard and operability) worksheet is the process safety study document. One row per node-parameter-deviation tuple carries the cause, consequence, severity, likelihood, the existing safeguards, the recommendation if additional protection is required, the recommendation owner, and the closure status. HAZOP guide words are the seven standard deviation modes: NO, MORE, LESS, REVERSE, AS WELL AS, PART OF, OTHER THAN.
HAZOP study worksheet template with 13 columns covering node, parameter, deviation guide word, cause, consequence, severity, likelihood, existing safeguard, recommendation, recommendation id, assignee, status, and closure reference. Pre-formatted with frozen header, auto-filter, and 48 blank rows. Free .xlsx download.

13 columns mapped to how a hazop study worksheet is issued on a real project. Dropdown columns enforce values; free-text columns let house notation preserve as drawn.

What ships in the file.
Worked example
One filled row shows the format for every column so the schema is clear before the engineer starts typing.
Auto-filter
Enabled on every column. Pivot by any field without a single formula.
48 blank rows
Pre-formatted and ready to paste into. Extends without breaking the dropdown or filter range.
Enforced dropdowns
Categorical columns (priority, signal class, status, type) enforce values so the register stays clean.
Cross-tool
Plain .xlsx. Opens cleanly in Excel, Google Sheets, and LibreOffice. No macros, no add-ins.
No tracking
No signup, no email gate, no telemetry inside the file. Download, edit, ship.
Quiet signoff
A single mint-italic line at the bottom: Drag a source document at tagsight.io to fill this automatically. Easy to delete.
Tagsight reads the source document, extracts every row, and returns the same 13-column schema this template defines. Type, tag, vendor, model, and per-row metadata are populated from the document itself.
Scanned binders, CAD-exported PDFs, and image scans all work. House conventions, vendor-specific forms, and dialect-specific tag schemes read as drawn.
