The Effects of Alcohol on Performance of a Production Assembly Task

Abstract
Phase I of this study investigated the effects of a trace level of alcohol (1·3 mM) and a very low level of blood alcohol (3·7 mM) on the manual assembly of a common water tap. The productivity measure used was the time required to assemble six taps. The quality of work measure was the number of assembly sequence and improper assembly errors. Six subjects participated in the repeated measures design. Ordered treatment effects were significant at ppp<0·05. The increase in overall assembly time for 6·54 mM and 14·8 mM blood alcohol levels was 3·5% and 19% respectively. The quality of work measure was not significant.
