Safety Boundaries

CalcMason apps provide calculation aids. Results do not approve work, authorize regulated activity, or replace official references.

Construction, Electrical, Plumbing, HVAC, Welding, And Shop Work

Verify results with applicable codes, local authorities, qualified professionals, manufacturers, machine limits, site conditions, and shop procedures.

Aviation And Marine Use

Flight and marine calculations are training and planning aids only. They are not primary navigation, weather, chart data, flight-plan approval, or operational authority.

Dive Gas Use

The dive gas app performs gas arithmetic only. It does not calculate decompression status, no-stop limits, tissue loading, CNS exposure, or dive-table results.

Radio Use

Radio calculations and references do not authorize transmission. Operators remain responsible for license privileges, RF exposure compliance, and current regulations.
