The ACGIH TLV for Low Back Risk
The Lifting TLV (threshold limit value) was the product of a team of scientists whose goal was to develop
a lifting guideline that was accurate, used the latest scientific information, and easy to use. This group of
scientists consisted of Lawrence J. Fine, Christopher Hamrick, W. Monroe Keyserling, William S. Marras,
Robert Norman, Barbara Silverstein, and Thomas Waters with correspondence members consisting of
Peter Buckle and John W. Frank. The product of this group’s work has been presented as an ACGIH
2005 TLV. This chapter is based upon the work of the committee establishing this NIE (notice of
intent to establish) of which the two authors of this chapter were members.
