Abstract

Workers in oil and gas production units are at risk of exposure to chemical hazards. One of the ingredients in petroleum is volatile organic compounds (VOC), with examples of ingredients known for their toxicity being benzene, toluene and xylene. This study aims to assess health risks related to exposure to benzene, toluene and xylene of oil refinery workers at PT. X. This study will analyze personal exposure to inhalation routes from benzene, toluene and xylene chemicals using the Chemical Health Risk Assessment (CHRA) method from the Department of Safety and Health, Malaysia. The study results showed that the risk level from benzene was very high, while the risk level from toluene and xylene was at a moderate level. The highest exposure to benzene, toluene and xylene is in distillation units. Based on the results of the study, appropriate controls are needed to overcome exposure to benzene, toluene and xylene. One of the controls that can be done is to improve the ventilation system and tighten the use of personal protective equipment.

Bahasa Abstract

Pekerja pada unit produksi minyak dan gas bumi berisiko memberi pajanan terpajan bahaya kimia. Salah satu bahan dari minyak bumi adalah volatile organic compounds (VOC), dengan contoh bahan yang terkenal akan toksisitasnya adalah benzene, toluene dan xylene. Penelitian ini bertujuan untuk menganalisis risiko kesehatan terkait pajanan benzene, toluene dan xylene pekerja kilang minyak di PT. X. Penelitian akan menganalisis data pajanan personal rute inhalasi dari bahan kimia benzene, toluene dan xylene menggunakan metode Chemical Health Risk Assessment (CHRA) dari Department of Safety and Health, Malaysia. Hasil penelitian menunjukkan tingkat risiko dari benzene sangat tinggi, sedangkan tingkat risiko dari toluene dan xylene berada pada tingkat sedang. Pajanan tertinggi dari benzene, toluene dan xylene berada pada unit distilasi. Berdasarkan hasil penelitian, diperlukan pengendalian yang tepat untuk mengatasi pajanan benzene, toluene dan xylene, Salah satu pengendalian yang dapat dilakukan adalah meningkatkan sistem ventilasi dan memperketat penggunaan alat pelindung diri.
