This app is designed to help industrial hygiene and occupational health and safety professionals quickly and accurately calculate various parameters related to occupational health and safety.
On the left side of the screen, you will find a menu with different categories of calculations, such as basic sciences (e.g., area of a circle, TWAs), noise, ventilation, etc. Simply select the category you are interested in to access the relevant equations.
The app allows you to input values in different units of measure, so you can easily convert between metric and imperial units. You can also adjust the number of digits of precision to suit your needs. When using the digits of precision function, be sure to select the digits first before selecting “calculate,” or if you change the digits of precision after calculation, press “calculate” again to get the updated results.
If you need more information about a specific calculation or parameter, simply click on the information button (put the icon here) in the upper right for a detailed explanation.
We hope you find this app helpful in your work and welcome any feedback or suggestions for improvement. Thank you for using the AIHA Industrial Hygiene Calculator app!
