OEMS Welding and Hot Work Calculator

A web version of the "Welding" tab of the OEMS Welding and Hot Work Calculator v1.0 DRAFT Google Sheet. It follows the OEMS Non-Manufacturing Welding and Hot Work Exposure Assessment Methodology v1.6 and Procedure v1.6. Yellow fields are entered or picked; green fields are calculated, as in the sheet.

Plain HTML, CSS, and JavaScript with no build step. Open index.html, or deploy as a static site (on Vercel, leave the framework preset as "Other").

• index.html: the page
• data.js: the Metals library and the Tables, copied from the sheet
• calc.js: the calculation logic, with the sheet cell each piece comes from
• app.js: connects the form to the calculation
• style.css: the styles
• tests/check.js: runs the scenarios in tests/scenarios.js and compares them with values read from the sheet (tests/sheet-results.json). Run node tests/check.js; add --markdown to write tests/results.md.

The ACGIH TLV and adopted other-source codes, which are entered on the sheet's Metals tab, are entered on each Gate 1 row here.

This tool supports the evaluator's professional judgment and does not replace it.
