To describe the circumstances surrounding firework-related deaths in Denmark, locate similarities and compare findings to the other known literature.Methods: Autopsy files, including police reports, located through searches in the archives of the three Danish institutes of forensic medicine. Data describing the age, sex, toxicology findings, circumstances of the accident, cause of death, autopsy findings and type of fireworks were examined.Results: Eight total cases involving firework-related deaths matched the search criteria, two of which occurred on New Year's Eve. An unknown number of cases that have not been autopsied were confirmed to exist. Data from the included cases suggest that using illegal fireworks, being male and directly handling fireworks play a key role in deaths. Most notably, illegal fireworks account for few injuries overall but caused the most deaths found in this study. Conclusion:Firework-related deaths are a rare occurrence. Autopsy findings often reveal blast wave injury to be the cause of death. Legislation seems to influence both injuries and death, but further action and focus on preventing deaths from illegal fireworks might be needed. Cases not included in this study can possibly help determine further action.
