Occupational Carbon Monoxide Poisoning Associated with Diesel Motor Operation in an Air-raid Shelter in June 2015, Jinan City, China-An Epidemiological Investigation.

Occupational carbon monoxide (CO) poisoning related to diesel motor fumes in an air-raid shelter (ARS) was first identified in Jinan City, China, in June 2015. A total of 17 cases were identified, including 14 possible cases of firemen and 3 confirmed cases of water channel clean-up workers. The overall attack rate (AR) of firemen was 42% (14/33). The firemen had a significantly higher AR with a longer exposure and more protracted time of rescue in the ARS (P < 0.05). All the cases stated that they did not realize the potentially high level of exposure to CO in the ARS. CO poisoning posed a risk to both patients and service providers. Occupational safety and health education should be promoted and enforced in all workplaces where CO sources exist.
