The relationship of subjective distress and emergency response experience to the effective use of protective equipment

A total of 11 1 chernical emergency response team members were evaluated on the effective use ofpersonal protective equipment (PPE) and self-contained breathing apparatus (SCBA) whde participating in a series of simulated hazardous material accidents. Performance ratings of PPE and SCBA use were conducted via behaviourally anchored rating scales (BARS), self-estimates of effectiveness, and cohort ratings. Subjective distress was assessed via the Subjective State Change Measure (SSCM), State-Trait Anxiety Inventory, and the Framingham Type A Behaviour Scale. Results indicated that effective use ofprotective breathing apparatus was correlated with prior emergency response experience and state anxiety. BARS scores were negatively related to state anxiety when controlling for experience. Self-ratings for effectiveness was positively related to both type A behaviour pattern and state anxiety.
