An evaluation was conducted to investigate the prevalence of asbestos (1332214) related pleural plaques among seamen. The evaluation was made of seamen over age 50 who were reported to have worked in uncontrolled environments on board ships and who certainly exceeded the latent period for the development of pleural plaques. Among 90 members in the engineering group, nine were observed to have plaques. Their duration of work had been 27 to 39 years. Plaques were demonstrated in only three out of 136 deckmen and stewards whose duration of work was 28 to 37 years. Of the three deckmen with pleural plaques, one had worked exclusively as a wireless radio operator, while the other two had engaged in miscellaneous work before being promoted to deckmen. Plaques were observed in 20 out of 146 workers at steam locomotive repair shops but in none of the 100 clerical staff at the same company. The authors suggest that older seamen or retired seamen be followed carefully in every ocean going country.
