چکیده

اره‌موتوری یکی از خطرناک‌ترین وسایل کار در جنگل است که احتمال آسیب‌رسانی زیادی برای کارگر قطع به همراه دارد. مدیریت خطرات ناشی از کار با اره‌موتوری به ارزشیابی خطرات آن بستگی دارد. تاکنون یک روش مناسب برای ارزیابی ریسک کار با این وسیله ارائه نشده است و عموماً خطرات کار با اره‌موتوری بدون رتبه‌بندی ارائه شده است. این تحقیق با هدف رتبه‌بندی خطرات ناشی از کار با این وسیله طرح ریزی شده است. برای شناسایی خطرات مربوط به کار با اره‌موتوری در هنگام انجام عملیات قطع درختان از روش آنالیز ایمنی شغلی استفاده شد. بدین منظور از نظرات کارگران اره‌موتورچی، ناظران عملیات قطع، کارشناسان بهره‌برداری و کارشناسان بخش ایمنی کار در جنگلِ مجریان بزرگ طرح‌های جنگلداری در جنگل‌های شمال استفاده شد. سپس شاخص‌های ارزیابی ریسک با استفاده از روش دلفی و با کمک کارگران قطع، مدیران حوزه‌های جنگلی، متخصصین و اساتید دانشگاه انجام و توسط کارشناسان ایمنی کار در جنگل جمع‌بندی شد. سرانجام رتبه‌بندی خطرات با استفاده از روش تاپسیس فازی انجام شد. نتایج تحقیق نشان داد که درختان خطرآفرین، برگشت به عقب انتهای تنه درخت پس از افتادن و لگدزدن اره‌موتوری مهم‌ترین خطرات کار با این وسیله می‌باشند. این تحقیق با رتبه‌بندی خطرات کار موجب افزایش قدرت تشخیص خطرات کار با اره‌موتوری و تعیین شاخص‌های صحیح ارزیابی ریسک شد و نتایج نهایی منتج به رتبه‌بندی خطرات کار با این وسیله گردید که با تدوین دستورالعمل ایمنی مناسب می‌توان حوادث ناشی از کار با این وسیله را کاهش داد.

چکیده [English]

Chainsaw is the main dangerous equipment in forest work which has great potential damage to felling crew. Management of the risks arising from working with a chainsaw depends on the assessment of its risks. There is still no suitable method for evaluating the risk of work with this device. Generally, the risks of working with chainsaw are presented without rating. This study was designed to rank the dangers of working with this device. For investigation of dangers related to chainsaw during tree felling Job safety analysis was used. During these phase, comment of chainsaw men, felling operation supervisors, harvesting experts, and Work safety specialists working in forestry plan in Caspian forest were used. Then, the risk assessment criteria were investigated by Delphi method with help of felling workers, forest watershed managers, forestry specialist, and university professors. Results were Conclusion by forest safety experts. Finally, the risk ranking was done using the Fuzzy Topsis method. Risk assessment criteria were obtained using the Delphi method. Ranking of hazards with Fuzzy Topsis was determined. The results of this study showed that the dangerous trees, butt log and chainsaw kickback are the most important risks of chainsaw operation. This study enhanced the ability of risk detection of felling operation with chainsaw and correct risk assessment criteria identification with ranking of felling hazards. The final analysis resulted in rating the dangers of working with this device that it can reduce the incidents caused by working with this device by compiling the appropriate safety instructions.
