Analysis on Epidemic Characteristics of Non-occupational Carbon Monoxide Poisoning in Jinan from 2007 to 2016

Objectives This paper analyzed the information on poisoning events of non-occupational carbon monoxide (CO) in Jinan from 2007 to 2016, and knew well its epidemiological characteristics, and explored the targeted and control prevention measures.

Methods Based on the monitoring of the emergency plan for non-occupational carbon monoxide poisoning, the descriptive analysis method was used to analyze the data, and the chi square test descriptive analysis method was used.

Results From 2007 to 2016, there were 3 311 cases of non-occupational CO poisoning reported in Jinan, involving 4 794 cases, 161 deaths and 3.36% fatality rate. The poisoning of 96.22% (3 186/3 311) occurred in the family, and 99.88% (3 307/3 311) of the non-occupational CO poisoning incidents were not classified. Non-occupational CO poisoning concentrated occurred in the winter nights, with the peaks of November to March. There was no statistically significant differences in the fatality rate caused by poisoning events in urban streets and towns (χ²=6.00, P>0.05).

Conclusions To reduce the occurrence of the event, it is necessary to promote the renovation of heating facilities, and to use the stove far away from living room, external heating, or central heating; To promote the installation of CO alarms in residential households; In winter, the prevention of non-occupational CO poisoning is widely used to promote education activities, especially in October before the heating season. Early detection, early rescue can reduce the fatality rate effectively.
