Where do the default values come from?

They are illustrative plant numbers so each page shows a worked answer. Replace them with the figures from your own OSHA log, time records, payroll and procedures.

Why do some results show a warning?

A warning means the plan fails a limit you entered or one from a cited source, such as an incident rate above your target or a workload beyond the hours available. The message states the gap and what to change.

Can I download the calculation?

Yes. Every calculator has an Excel workbook with live formulas that match the page, so you can check the math or reuse it in a quote.

Why is a result blank?

An input is missing or outside its valid range, so there is no honest number to show. The message above the result names the input to fix.
