Objective: To investigate anecdotal reports suggesting that repeated exposure to low-level explosive blast has myriad health impacts, including an array of neurological effects. Participants: A total of 184 anonymous survey respondents from military and nonmilitary law enforcement populations (135 exposed to occupational blast and 49 controls). Design: Survey of self-reported history of occupational exposure to repeated low-level blast (breaching blast) and symptomology similar to concussion. Results: Findings suggest that number and severity of symptoms increase with history of chronic blast exposure (F = 18.26, P < .001) and that symptoms can interfere with daily activity (t = 2.60, P = .010). Conclusion: Given the prevalence of repeated exposure to blast among some military and civilian law enforcement occupations, the results of this survey study support a role for blast surveillance programs as well as continued research on health impacts of low-level repeated blast exposure.
