The petrochemical field is an industry seeking to increase efficiency, improve safety of workers, and lessen environmental impacts (U.S. Chemical Safety & Hazard Investigation Board, 2007). One way to improve the performance of operators is to investigate their situation awareness (SA). Research has shown that SA is a predictor of performance (Durso et al., 1999). However, there is little consensus on how to measure SA. This study investigated two prominent techniques for measuring SA: the Situation Present Assessment Method (SPAM; Durso & Dattel, 2004) and the Situation Awareness Global Assessment Technique (SAGAT; Endsley, 1995b). These two techniques were examined for their psychometric properties in assessing SA among operators. The results of this investigation showed that probe-type SA techniques can be used to assess SA in this field. This especially applies to the SPAM technique, which was shown to predict performance, not intrude, and was preferred by a majority of operators.
