Abstract: | Objective To grasp the occupational hazards status in workplace,and guide the work of the occupational hazards prevention and control. Methods Worksite survey of occupational health included survey on the production process,occupational hazards distribution,occupational disease prevention facilities and personal protective protection equipment.Testing and evaluation work was on the basis of national standard. Results The occupational hazards in this project were limestone dust,noise and so on. As the test results showed,the dust concentration of all detecting points met the national standard,and the heaviest dust concentration was 2. 93 mg /m3. The noise exposes of operators on in- the- hole drill and excavating machinery were 86. 0 dB and 90. 6 dB,which were over the occupational standard limit. Conclusion The harm of dust and noise should be paid more attention. Protection from occupational hazards should be focus on the management of occupational disease prevention facilities and individual protective equipment wearing. |
