ORMANCILIK ÜRETİM İŞLERİNDE ÇALIŞMA DURUŞLARININ İŞÇİ SAĞLIĞI AÇISINDAN DEĞERLENDİRİLMESİ

Year 2016, Volume: 18 Issue: 1, 47 - 56, 08.06.2016

Abstract



Orman işçileri gerek fiziksel çevre faktörleri gerekse
yaptıkları işten dolayı çeşitli yüklere maruz kalmaktadırlar. Çalışma
sırasındaki hatalı duruşlar kas iskelet sistemi rahatsızlıklarına sebep olmakta
ve işçilerin performanslarını olumsuz yönde etkilemektedir. Bu çalışmada, motorlu
testere ile çalışan orman işçilerinin bölümlere ayırma çalışmaları sırasındaki
çalışma duruşları belirlenmiş ve bu duruş şekillerinin kas iskelet sistemi
rahatsızlıkları üzerindeki etkileri tespit edilmiştir. Bu kapsamda, en fazla
oranda görülen iki farklı çalışma duruşu üzerinde ergonomik analizler
yapılmıştır. CATIA V5 programı ergonomik tasarım ve analiz modülü yardımı ile
işçilerin çalışma sırasındaki kol-üst vücut kaslarındaki yorulmalar
belirlenmiştir. Yine, biyomekanik eylem analizleri ile işçilerin çalışma
sırasında kas iskelet sistemi üzerinde maruz kaldığı yükler tespit edilmiştir.
Yapılan RULA analizleri sonucu en uygun ergonomik çalışma duruşu belirlenmiş,
analiz final puanı 7’den 3’e indirilmiştir. L4-L5 bel omuru disklerinde oluşan
basınç yüklemesi 176 N/m2’den 94 N/m2’ye (% 53,4) ve moment yüklemesi 3034
Nm’den 2011 Nm’ye (% 66,28) düşürülmüştür. Analiz sonuçlarına göre işçilerin
daha rahat ve güvenli bir şekilde çalışmaları için en uygun çalışma duruşu
belirlenmiş, uyarı ve öneriler sunulmuştur.

EVALUATION OF WORKING POSTURES IN TERMS OF OCCUPATIONAL HEALTH IN FOREST HARVESTING OPERATIONS

Year 2016, Volume: 18 Issue: 1, 47 - 56, 08.06.2016

Abstract

Forest workers are exposed to various loads due
to their jobs and physical environmental factors. Awkward postures lead to
musculoskeletal disorders (MSD’s) and negatively affect worker performance
during the operation. In this study, working postures of forest workers,
working with chainsaw bucking works were determined during the bucking works
and the effects of working postures on the MSD’s have been identified. In this
context, ergonomic analyses were conducted on the most frequently encountered
in two different working postures. Muscular fatigues in the arms and upper
limbs of workers have been identified using ergonomic design and analysis
module of CATIA V5 software. Also, the loads that the workers are exposed to on
their musculoskeletal system at the time of working were found with biomechanics
single action analysis. As a result of the RULA analysis carried out, the
optimum ergonomic working posture was identified and the final analysis score
was reduced from 7 to 3. Compression and moment loads on L4-L5 lumbar disc have
been reduced from 176N/m2 to 94N/m2 (53.4%) and from 3034Nm to 2011Nm (66.3%),
respectively. At the end of the study, the optimal working posture of workers
for more convenient and safe way to work was identified and suggestions were
presented.
