Example of a worker’s job for illustrating exposure classification. Job1 represents the longest job performed in the day and thus it is the typical exposure for the Strain Index (SI) and Threshold Limit Value for Hand Activity Level (TLV for HAL). Job2 represents the peak exposure for the SI and Jobn represents the peak exposure for the TLV for HAL as it has the highest threshold limit value, which exceeds the TLV.
