Bir Saha Çalışması: Süt Ürünleri Üretim Tesislerinde Termal Konfor

Öz

Bu çalışmanın amacı, sektörde çalışan işçilerin termal konfor durumlarını belirlemek ve soğuk ve sıcak etkilerine yönelik önlemler sunmaktır. Ölçümler Kocaeli çevresinde bu kapsamda faaliyet gösteren 9 işletmede 2016 Şubat ayı ile Ekim ayı arasında 123 noktada ISO 7726 standardına uygun olarak gerçekleştirilmiştir. Değerlendirmeler üç ana gruba ayrılmıştır; normal, soğuk ve sıcak ortamlar. Bu ortamları değerlendirmek için sırasıyla PMV, IREQ ve WBGT yöntemleri kullanılmıştır. Yöntemlerin kullanılmasında özel bir sıra izlenmiştir. Ayrıca çalışanların sosyodemografik özellikleri ve ortam kaynaklı şikayet ve önerilerini belirlemek için anketler kullanılmıştır. Yapılan ölçümler sonucunda 20 noktada IREQ değeri elbise yalıtım değerinden küçük çıkmıştır. 10 noktada WBGT değeri referans değerin üzerinde çıkmıştır. 36 noktada ise sıcaklık WBGT sınır değerine çok yakın çıkmıştır. Anketlere göre ise genel olarak çalışanların havalandırma yetersizliğinden, iş kıyafetinden ve cereyan (hava akımı) etkisinden rahatsız oldukları görülmüştür.

Anahtar Kelimeler

• Termal konfor
• İş sağlığı ve güvenliği

A Field Study: Thermal Comfort in Dairy Production Plants

Öz

The aim of this study is to determine the thermal comfort conditions of workers in the industry and to provide measures for the effects of cold and heat. The measurements were carried out in accordance with ISO 7726 standard at 123 points between February 2016 and October in 9 enterprises operating in this scope in the Kocaeli region. The evaluations are divided into three main groups; normal, cold and hot environments. PMV, IREQ and WBGT methods were used to evaluate these environments, respectively. A special order has been followed in the use of the methods. In addition, questionnaires were used to determine the sociodemographic characteristics of the employees and their complaints and suggestions related to the environment. As a result of the measurements made, the IREQ value at 20 points was lower than the suit insulation value. At 10 points, the WBGT value exceeded the reference value. At 36 points, the temperature was very close to the WBGT limit value. According to the surveys, it was observed that the employees were generally disturbed by the lack of ventilation, work clothes and the effect of draft (air flow).
