Acute occupational phosphine intoxications in the maritime shipping sector: a scoping review.

The aim is to assess the prevalence and knowledge on acute occupational exposure to phosphine in the shipping industry. We followed PRISMA guidelines for scoping review. We searched in 4 databases without language and date restrictions for scientific articles in peer-reviewed and gray literature. We found 13 peer-reviewed articles and 63 articles in gray literature. These covered 56 incidents from 1963 to 2019 for a total of 254 victims and 22 fatalities. There is an increase in the number of reported cases over the last 20 years. Neurologic and gastrointestinal symptoms are predominant, and hospitalization is needed in 80% of cases. Our review underlined the principal risk as gas exposure through leaks between holds and the ventilation system. Further studies on the knowledge and the prevention in order to improve good practices onboard, prevent the risk of fire explosion, and a global reporting system of new cases are recommended.
