Hand-Arm Vibration Calculator

Hand-arm vibration syndrome can be debilitating condition but it is still easy to prevent by limiting exposure below the threshold limit value. The worker’s exposure level can be determined by knowing the several of power tool's magnitude and the duration each exposure. Therefore the control measures can be determined as a preventive measure in preventing occupational disease caused by Hand-Arm Vibration exposure.

This android-based application was developed as one software that can be used by industrial hygienist practitioners in the field to evaluate the hand. This application is accurate and easy to use wherever even when you are offline.

Enter the tool’s name, tool’s magnitude and exposure duration, this application will automatically:

• Estimate the time to reach the threshold limit value, that indicated how long can safely use the tool

• Determine each partial exposure.

• Display color changes on each worker’s exposure, thus giving a warning signal to industrial hygienist's for extreme exposure to each power tools

• Estimate the worker’s total exposure from the various power tools operated in a series of process (more than 5 type of power tools)
