Effects of Regulations on the Choice of Ergonomic Methods: A Comparative Survey of California and New York Ergonomists

Abstract

A survey of 57 ergonomists in California and 28 ergonomists in New York State compared which of 19 ergonomic methods were used to assess potential injury risks. Results showed great variability in methods chosen by practitioners both within and between States. The Cal/OSHA regulation apparently has not standardized method selection in California. Apart from use of the NIOSH lifting equation for assessments of lifting and the Borg RPE scale for assessing exertion, there was no evidence of any standardization among practitioners in either State. There was no consensus on methods for assessing posture, repetitiveness, or force. Significant confusion was found among California practitioners regarding the content of the current Cal/OSHA regulation.
