ABSTRACT
The TLV for hand activity is intended to protect most workers from musculoskeletal disorders for the hand, wrist, and forearm. Workers with predisposing health conditions such as arthritis, endocrinological disorders, obesity, pregnancy, old age, or previous injuries may be affected by exposures below the TLV. It is likely that exposures below the TLV may produce some discomfort, but it should not persist from day to day or interfere with activities of work or daily living. The ACGIH TLV is designed to prevent only work-related cases. Employers should educate workers about nonwork-related causes of musculoskeletal disorders and how they can minimize their risk.
