Abstract

This study aims to evaluate and map the occupational noise emissions generated by band saw machines in the timber and forest products industry under different operating conditions. Field measurements were carried out across 25 active sawmill enterprises in Kahramanmaraş, Turkey, in compliance with the ISO 9612 (2025) standard. Noise levels were monitored using a calibrated TESTO 815 sound level meter at the operator's ear level under two operational states: idle and loaded (active wood cutting). The collected data were analyzed using descriptive statistics and a Paired-Samples t-test. The empirical results showed that the average equivalent noise level (Leq) of band saw machines during idle operation was 85.29 dB(A). Upon transitioning to the loaded cutting state, the noise level increased significantly to an average of 100.05 dB(A) (p < 0.001), representing a net average increase of 14.76 dB(A). Furthermore, the average maximum instantaneous noise level (Lmax) during cutting operations reached 104.95 dB(A), with peak values hitting 108.13 dB(A). These findings indicate that band saws emit hazardous noise levels that systematically exceed the international permissible exposure limits of 85 dB(A) set by the ILO, even while idling. Despite these severe risks, low personal protective equipment (PPE) utilization was observed among the workers. The study concludes that engineering controls, administrative exposure rotations, and comprehensive programs to improve occupational health literacy are urgently required in regional sawmill operations to prevent irreversible noise-induced hearing loss.

Özet

Bu çalışma, kereste ve orman ürünleri endüstrisinde şerit testere makinelerinin farklı çalışma koşulları altında ürettiği mesleki gürültü emisyonlarını değerlendirmeyi ve haritalandırmayı amaçlamaktadır. Saha ölçümleri, Kahramanmaraş'ta (Türkiye) aktif olarak faaliyet gösteren 25 kereste fabrikasında, ISO 9612 (2025) standardına uygun olarak gerçekleştirilmiştir. Gürültü seviyeleri, kalibre edilmiş bir TESTO 815 gürültü ölçüm cihazı kullanılarak, operatörün kulak hizasında iki farklı çalışma durumunda izlenmiştir: boşta (çalışırken) ve yüklü (aktif ahşap kesimi). Toplanan veriler, tanımlayıcı istatistikler ve Eşleştirilmiş Örneklemler t-Testi kullanılarak analiz edilmiştir. Ampirik sonuçlar, şerit testere makinelerinin boşta çalışma sırasındaki ortalama eşdeğer gürültü seviyesinin (Leq) 85,29 dB(A) olduğunu göstermiştir. Yüklü kesim durumuna geçildiğinde gürültü seviyesi, net ortalama 14,76 dB(A)'lık bir artışı temsil edecek şekilde, anlamlı bir artış göstererek ortalama 100,05 dB(A)'ya (p < 0.001) yükselmiştir. Ayrıca, kesim işlemleri sırasında kaydedilen ortalama maksimum anlık gürültü seviyesi (Lmax) 104,95 dB(A)'ya ulaşmış, pik (en yüksek) değerler ise 108,13 dB(A)'yı bulmuştur. Bu bulgular, şerit testerelerin boşta çalışırken bile ILO tarafından belirlenen 85 dB(A)'lık uluslararası izin verilebilir maruziyet sınırlarını sistematik olarak aşan tehlikeli gürültü seviyeleri yaydığını göstermektedir. Bu ciddi risklere rağmen, işçiler arasında kişisel koruyucu donanım (KKD) kullanımının düşük olduğu gözlemlenmiştir. Çalışma; geri dönüştürülemez gürültüye bağlı işitme kayıplarını önlemek amacıyla, bölgesel kereste fabrikası işletmelerinde mühendislik kontrollerinin, idari maruziyet rotasyonlarının ve mesleki sağlık okuryazarlığını artırmaya yönelik kapsamlı programların acilen uygulamaya konulması gerektiği sonucuna varmaktadır.
