A survey of UK firefighters revealed them to be seemingly psychologically prepared for what their job would expose them to but not immune to experiencing emotional arousal or perceived risk during emergency events. A number of aspects, such as the event posing serious consequences to their lives/well-being, were singled out as particularly distressing and linked with greater emotional arousal, while other aspects, ones focused on other people/circumstances, reduced perceived risk. Traffic accidents appeared to be a special case, inducing lower arousal and risk than another commonly attended emergency, domestic fires. More years of service had a positive effect on the risk perceived during a stressful event but heightened the emotional arousal in that moment. Received support was one of the most significant predictors of posttraumatic stress and growth, as well as being significantly linked to peri-event thoughts/feelings, although other variables not tested here, e.g. individual differences, might be better at explaining posttraumatic states than event-related variables. The sample reported that safety work with a risk group, migrants, was underway and appeared to be beneficial in reducing instances of "inappropriate behaviour" during emergencies but communication difficulties were an issue and training on this matter would appear desirable. Significant differences in responses across the UK were detected and consequences for international comparisons are discussed
