"Latar Belakang: Asam tioglikolat (TGA) yang digunakan sebagai bahan baku corrosion inhibitor dapat menghasilkan H2S (hidrogen sulfida) dan memajan kesehatan pekerja. Tujuan penelitian adalah menganalisis tingkat risiko H2S dari TGA dalam produk CI beserta usulan pengendalian risiko di perusahaan. Metodologi: Chemical Health Risk Assessment (CHRA) menurut DOSH versi 2018 pada dua unit kerja terpajan di PT. X, yaitu Unit kerja 1 (area produksi) dan Unit Kerja 2 (area warehouse). Hasil: Sesuai DOSH, tingkat risiko kesehatan gas H2S termasuk hazard rating (HR) = 5. Analisis exposure rating (ER) secara kualitatif menunjukkan ER area produksi (4) lebih tinggi dari ER di area warehouse (3) karena perbedaan frequency-duration rating (FDR) antar unit kerja. Dengan menghubungkan Magnitude rating (MR) saat aktivitas membuka tutup drum CI = 4, tingkat risiko kesehatan berada pada high risk level (RR = 20 Unit Kerja 1; RR = 15 Unit Kerja 2). Kesimpulan: Risiko kesehatan akibat pajanan H2S dari CI termasuk pada high risk level menurut CHRA DOSH dan langkah utama yang perlu dilakukan adalah subsitusi untuk menurunkan level risiko. Kesesuaian langkah pengendalian teknis, administratif, dan APD sangat penting saat TGA digunakan dalam produk corrosion inhibitor.

Background: Thioglycolic acid (TGA) is used as iron ion reduction in corrosion inhibitor which can produce H2S (hydrogen sulfide) and expose to human health. The purpose of this research is to analyze the risk level of H2S exposure from CI along with the proposed risk control in the company. Methodology: Chemical Health Risk Assessment (CHRA) according to DOSH (2018) in two exposed work units in PT. X (Work Unit 1 as production area and Work Unit 2 as warehouse area). Result: According to DOSH, the hazard rating of H2S is 5. Qualitative exposure rating (ER) analysis shows the ER of the production area (4) is higher than ER in the warehouse area (3) due to the difference in frequency-duration rating (FDR). By considering the Magnitude rating (MR) during drums opening is 4, the level of health risk is at high risk level (RR Work Units 1 = 20; RR Work Units 2 = 15). Conclusion: H2S exposure from CI is at high risk level according to CHRA DOSH and the main required control is substitution to reduce the risk level. Adequacy of technical, administrative, and PPE control measures is critical when TGA is used in corrosion inhibitor."

"Laboratorium Migas merupakan tempat kerja untuk melakukan pengujian, penelitian, dan pengembangan minyak mentah, produk sampingan, hingga produk jadi menggunakan peralatan dan bahan yang ada. Laboratorium memiliki banyak bahaya di dalamnya, tak terkecuali dengan bahaya kimia seperti benzene, toluene dan xylene (BTX). Oleh karena itu, diperlukan kajian risiko kesehatan di Laboratorium Migas untuk mengetahui seberapa besar tingkat risiko BTX terhadap pekerja laboratorium. Kajian risiko kesehatan ini akan mengacu pada CHRA DOSH Malaysia (2018) dimana data yang didapatkan dianalisis menggunakan IHSTAT. Kajian risiko kesehatan dilakukan menyesuaikan dengan SEG yang sudah ditentukan, yaitu unit Crude & Product Classification, unit Facility & Quality, unit Fuel, unit Analytical & Gas, serta unit Petrochemical. Hasil dari penelitian menunjukan bahwa terdapat tingkat risiko yang tinggi pada pajanan benzene melalui rute inhalasi serta rute dermal terhadap unit Fuel. Sementara itu, pajanan xylene dan toluene berada pada tingkat risiko yang rendah untuk rute pajanan inhalasi serta berada pada tingkat pajanan moderat pada rute pajanan dermal. Dari hasil penelitian terkait tingkat risiko keseharan pada pajanan benzene, toluene, dan xylene, diperlukan peningkatan kesadaran pekerja untuk menggunakan APD tambahan serta peningkatan sistem ventilasi di tempat kerja.

The Oil and Gas Laboratory is a workplace for conducting testing, research and development on crude oil, by-products and finished products using existing equipment and materials. Laboratories have many dangers in them, including chemical hazards such as benzene, toluene and xylene (BTX). Therefore, it is necessary to study health risks in oil and gas laboratories to find out how big the risk level of BTX is to laboratory workers. This health risk study will refer to CHRA DOSH Malaysia (2018) where the data obtained was analyzed using IHSTAT. Health risk studies are carried out in accordance with the SEGs that have been determined, namely the Crude & Product Classification unit, Facility & Quality unit, Fuel unit, Analytical & Gas unit, and Petrochemical unit. The results of the study show that there is a high level of risk of exposure to benzene via the inhalation route and the dermal route on Fuel units. Meanwhile, exposure to xylene and toluene is at a low risk level for the inhalation exposure route and at a moderate exposure level for the dermal exposure route. From the results of research regarding the level of health risk from exposure to benzene, toluene and xylene, it is necessary to increase worker awareness to use additional PPE and improve the ventilation system in the workplace."
