Abstract:
OBJECTIVE: To compare the applicability of three risk assessment methods on occupational health risk assessment of chemical harmful factors in a resin anchorage production workshop. METHODS: A resin anchoring agent production workshop was selected as the research subject using the judgment sampling method. Contact ratio assessment method and comprehensive index method(both are semi-quantitative evaluation method) and qualitative risk assessment method were applied to estimate the occupational health risks of jobs involved with styrene, dibutyl phthalate and phthalic anhydride. The assessment was carried out, and the obtained risk level was standardized as the risk ratio. The evaluation results of these three methods were compared. RESULTS: The assessment results of exposure ratio method were 1-3, and those of comprehensive index method were 2-3. The risk ratio of the above methods after standardization is consistent with that before standardization. The result of qualitative risk assessment was 2-3, and the risk ratio after standardization was 3-4. The risk ratio after standardization was 1 level higher than that before standardization. Kappa analysis results showed that the result of contact ratio method and the comprehensive index method was in good agreement(Kappa=0.53, P<0.05). The qualitative risk assessment method was inconsistent with the contact ratio method and the comprehensive index method(Kappa values were 0.19 and 0.40, both P<0.05). CONCLUSION: Comprehensive index method is the preferred method for occupational health risk assessment of anchorage agent production workshop under the condition that detection results of occupational hazards can be obtained. Qualitative risk assessment method can be used when the test results cannot be obtained.
