Prevalence Study About Occupational Health And The Health Status Of Workers At Gas Station

ObjectiveThe authors hope that through this observational study, understandoccupational health and the health status of workers at gas station of Taian City.Preliminary understanding of the Occupational characteristics in gas station.And regular contact with gasoline pollution hazards status quo, Regular contactwith gasoline pollution Harm Situation. Provide baseline information foroperating environment risk assessment who working in gas station and gasolineexposed populations. Preliminary corrective recommendations for industryoccupational health problem. To provide a scientific basis for occupationalexposure to gasoline poisoning and occupational skin disease prevention,treatment and supervision and management.MethodsStratified randomly selected in proportion to randomly selected114gasstations from the Tai’an City and the use of the national norms detection methodto detect the gas station scene detection data set; using self-designedquestionnaire to the observation group (114service stations operating works),two populations of the control group (not exposed to gasoline supermarketattendant) occupational health examination and to obtain the relevant data.All data for statistical analysis, the quantitative data of the two groupsusing T test, multiple group comparison using analysis of variance, and qualityative data using the chi-square test, logistic regression analysis to identify occupational hazards factors.ResultsPart1Gas station status analysis1、 Gas station establishment and implementation of occupational healthmanagement system. Most of the gas stations didn’t establish various occupational healthmanagement system. Only2gas stations had occupational health managementsystem. While94.7%workers of gas stations didn’t take occupational healthexaminations before take up their jobs.9.6%gas stations didn’t set warning labels and the card to introducing theharmful effects of the occupational disease, meanwhile, workers lack therelevant occupational health knowledge and protective consciousness.2、 Field gasoline concentration detectionThere were114gas stations to be detected with the solvent gasoline, ofwhich112were qualified, accounting for the qualified rate of98.2%. Accordingto the results of the gasoline concentration, the maximum instantaneous massconcentration is426.2mg/m~3, of which98.2%of the sample concentration werelower than the national standard (300mg/m~3), what’s more,the92.7%werelower than100mg/m~3. Consequently, the workers belonged to the long-termexposure to low concentration at their working period.Part2Gas station workers occupational health and the health effects ofoccupational hazard factors.1、 Comparing the survey indicators in the two groups.The workers of the observation group felt dizziness、headache、insomnia、dreaminess、hyporemenber、inattention and had chapped skin, whose proportionof self perception disorders was higher than those of control group（P<0.01）.2、 The satisfaction in the workplace environment conditions.66.9%in the observation group felt dissatisfied with the workingenvironment, while the rate was44.6%in control group. The difference wasstatistically significant（Z=11.984， P<0.01）3、 Physical examination situation analysis.Each index of anomaly detection was respectively: high blood pressure(17.8%),white blood cel（l9.8%）、red blood cel（l12.7%）、hemoglobin（21.4%）、blood platelet cell（7.9%），liver function（5.4%）、blood fat（28.2%）routineurine（25.4%）， fatty liver（18.8%）， neurasthenia syndrome(16.8%）， skindetection and dry chapped skin（14.1%），the above indicators were higher thanthose of control group（P<0.05）. 4、 Recognizing to factors of occupational hazards and the training needOnly58%workers knew more about the occupational hazard, while33.2%knew little about it, and even knew nothing.74%workers thought it extremelynecessary to get the training about the occupational hazard and protectivemeasurements.5、 Analysis of occupational hazard factors in observation groupSingle factor analysis Major professional related factors affecting theworkers health: sex、 working years、 type of work、 working location、 gasconcentration、 gasoline direct contact time per hour(minute)、 the cognizing tothe occupational hazard factors、 implementation of personal protectivemeasures、 satisfaction degree to the working environment.Multiple-factor analysis. Regression analysis results indicate that themajor occupational hazard factors affecting the health of workers are thefollowing: gasoline demonstrating compliance、 working location、 workingyears、cognizing to the hazard factors、satisfaction degree to the working placewhich were statistically significant（P<0.05）.And the most dangerous factorswere substandard gas concentration、 working years(more than10years),whoseOR were2.137and4.830respectively.ConclusionPart1General description of the gas stations1、 There is hardly any management system about the occupational healthstatus, and exist serious shortcoming in workers protective measurements andmanagement.2、 There are1.8%gas stations whose solvent gasoline are not conformingto the national health standards, which need enforced by supervisiondepartment and checked their implementations regularly.Part2Gas station workers occupational health and the health effects ofoccupational hazard factors1、 The research shown that low concentration contact with occupationalharmful factors for a long time will do harm to blood index、 routine urine、nervous system hematopoiesis system and skin. There are few systematicallyepidemiological studies on the health status of the workers in the petrochemical gas station system in our country. It is extremely necessary to do thesystematically detection and follow-up of observational studies.2、 The results of analysis indicate that the workers cognizing to thepoisonous and harmful factors and the protective measurements also have effecton the health, which may be relative to the workplace、 job category、workloadof the fuel charge、 the time exposed to the gasoline and the self-protectivemeasurements and so on.
