Time-Weighted Average (TWA) Exposure

⚠️ MOSH Calculator – TWA Exposure

Calculate the Time-Weighted Average (TWA) exposure to hazardous substances or physical agents over a specified period.

ℹ️ How to Use

1. Enter the concentration of the hazardous substance (e.g., ppm for chemicals or dB for noise) for each time period.
2. Enter the corresponding time interval (in hours) for each concentration period.
3. Enter the total time worked (usually 8 hours for a workday).
4. Click Calculate TWA Exposure to get the time-weighted average exposure.

⚠️ Concentration 1 (ppm or dB): ⏳ Time Interval 1 (hours): ⚠️ Concentration 2 (ppm or dB): ⏳ Time Interval 2 (hours): ⚠️ Concentration 3 (ppm or dB): ⏳ Time Interval 3 (hours):
