The following methods are comprehensive tools designed to provide a detailed analysis of various types of manual material handling tasks. They can be used to evaluate lifting, lowering, pushing, pulling, carrying, and other activities.
NIOSH Lifting Equation
The NIOSH Lifting Equation is a tool used to evaluate manual lifting tasks. This equation allows the user to insert the exact conditions of the lift (e.g., height, distance lifted, weight, position of weight relative to body, etc.). This equation accounts for asymmetrical lifts and objects that are diffi cult to grasp.
ACGIH Threshold Limit Values (TLVs) for Lifting
The American Conference of Governmental Industrial Hygienists (ACGIH) recommends guidelines for safe lifting. The Threshold Limit Values (TLVs) for lifting recommend upper and lower limits based upon frequency, duration, and other risk factors associated with lifting.
The following ACGIH Publications may be helpful:
- TLVs and BEIs (#0106)
- Lifting: TLV Physical Agents (7th Edition) Documentation (#7DOC-734)
To purchase publications, go to www.acgih.org/store or call (513) 742-2020.
University of Michigan 3D Static Strength Prediction Program
3D Static Strength Prediction Program software predicts static strength requirements for tasks such as lifts, presses, pushes, and pulls. The program provides an approximate job simulation that includes posture data, force parameters, and male/female anthropometry. The results include the percentage of men and women who have the strength to perform the described job, spinal compression forces, and data comparisons to NIOSH guidelines. The user can analyze torso twists and bends and make complex hand force entries. Analysis is aided by an automatic posture generation feature and three-dimensional human graphic illustrations.
Ohio State Lumbar Motion Monitor
Traditionally, most workplace ergonomic assessments have focused on joint loading in static postures. However, epidemiologic studies have shown that three-dimensional dynamic motion is associated with an increased risk of occupational injury and illness. The Biodynamics Lab has developed a unique research program that focuses on the study of occupational joint loading under realistic dynamic motion conditions.
The program's goal is to obtain a better understanding of how much exposure to realistic risk factors is too much.
Snook's Psychophysical Tables
These tables are based on psychophysical data and provide the maximum acceptable weights and forces for various common tasks including lifting and lowering weights, pulling and pushing forces, and carrying objects. Values are given for different lift heights, number of lifts per minute, and percentiles of male and female populations capable of the task.
