ABSTRACT
But adopting the NIOSH model to make assessments in the field of manual handling tasks did pose some problems. Here are three of them.
The American authors themselves (Waters et al. 1993) emphasize that the procedure is not applicable in some situations; such caution is quite understandable from a strictly scientific viewpoint, but in some cases it may be overcome by making assumptions based on empirical data. Suppose the load is lifted with one arm only, perhaps this could be included by introducing a further multiplication factor of 0.6.
