The transportation of fuel using the tank trucks haved consequences to thefires and explosions incident. This study is a quantitative modeling with input thesecondary data which applied in ALOHA (Areal Location of HazardousAtmosphere) software on one type of hydrocarbon that become Premiumcomponents, namely Pentane. The aims of this study was to determine theconsequences impact range of gas dispersion, fire and explosion due to tankleakage on fuel transportation using the tank truck in Surabaya and Jakarta. Theresults showed that the range and consequences of gas dispersion, fire, andexplosion for the three zones based on the level of concern of each scenario givedrisks to public safety, worker safety, environmental safety, andequipment/installation safety.Keywords: Gas dispersion, fire, explosion, Pentane, pool fire, BLEVE, VCE
Keselamatan kerja tercermin pada keadaan di tempat kerja, yang meliputi kondisi tak aman, tindakan tak aman maupun keadaan Iingkungart kerja, merupakan dasar dari kejadian hampir celaka maupun kecelakaan. Perlindungan keselamatan secara mekanikal peralatan sebagai perbaikan pertama dan langkah umum yang paling awal dilakukan, yang membatasi bahwa kondisi tak aman relatif sebagai penyebab kecelakaan. Inspeksi keselamatan kerja pemboran bertujuan sebagai sarana untuk mengenali potensial keadaan tak aman yang ada diberbagal fasilitas dan peralatan di lokasi pemboran yang berhubungan dengan rig pemboran darat. Temuan hasil inspeksi dianalisa dan diberikan rekomendasi untuk mengurangi dan atau menghapuskan kejadian hampir celaka dan kecelakaan pada operasi pemboran di PT. CPI. Penelitian ini adalah studi evaluasi dengan mempergunakan data tahun 2003 sampai dengan tahun 2005 di PT. CPI. Data penelitian ini adalah data sekunder yang merupakan data dari kebijakan dan program inspeksi keselamatan kerja pemboran serta data primes yang diperoleh melalui kuesioner untuk mengetahui pemahaman program inspeksi keselamatan kerja pemboran. Aspek Input adalah komitmen dan dukungan manajemen, hasilnya baik pada tahun 2003, 2004 dan tahun 2005 yang meliputi kebijakan dan program inspeksi keselamatan kerja pemboran serta dukungan sumber daya manusia. Aspek proses yakni penerapan program inspeksi keselamatan kerja pemboran pada tahun 2003 dan 2004 hasilnya kurang baik dan meningkat menjadi sangat balk pada tahun 2005. Aspek Output yaitu Nilai Positive Indicators yang sangat baik dari tahun 2003 s/d tahun 2005 dari program inspeksi keselamatan kerja pemboran di PT. CPI sudah dapat mencerminkan status pengelolaan keselamatan kerja pemboran dari fasilitas maupun peralatan yang dioperasikan. Komitmen dan dukungan manajemen pada tahun 2003 perlu peningkatan pemantauan program inspeksi, pelatihan dan keterlibatan karyawan perusahaan kontraktor pemboran melakukan inspeksi bersama tim inspeksi. Hasil yang kurang baik pada penerapan program inspeksi keselamatan kerja pemboran tahun 2003 dan 2004 disebabkan kurangnya pengawasan, kurangnya pemahaman pengawasan penyelesaian perbaikan. Pemenuhan keselamatan kerja rig pemboran yang sangat baik dari tahun 2003 s/d tahun 2005 karena perusahaan kontraktor pemboran telah melaksanakan inspeksi internal, mempunyai surat ijin iayak operasi (SILO) dan manajemen telah melakukan pengawasan secara lebih baik, keterlibatan karyawan meningkat serta adanya pemantauan dan evaluasi.
Occupational safety can be seen a lot from the situation at the workplace, which includes unsafe conditions, unsafe actions and also the situation of work environment. Safety protection which is done mechanically as a first improvement and the earliest general action taken, create a limitation that unsafe conditions seem to be considered as the main cause of accidents. Occupational safety inspection at drilling industry is aimed as means to recognize the unsafe conditions exist in many facilities and equipment at the drilling sites, which are related to ground drilling rig. The result of the inspection is then analyzed and given as a recommendation to decrease andlor eliminate nearly-accidents occurrence and accidents at the drilling operation in PT. CPI. This study is an evaluation study using data taken from 2003 until 2005 in PT. CPI. The data is a secondary data obtained from policies and occupational safety inspection program at drilling industry as well as primary data obtained from questionnaires in order to find out the acknowledgement and comprehension of occupational safety inspection program at drilling industry. The input aspect is management commitment and supports, the results are data either from 2003, 2004, or 2005 which include policies and occupational safety inspection program at drilling industry as well as human resource supports. The process aspect is the implementation of occupational safety inspection program at drilling company during 2003 to 2004, the result are not quite good yet improving to be very good in 2005. The output aspect is Positive indicators Value which is considered excellent from 2003 until 2005 in occupational safety inspection program at drilling industry PT. CPI. The program has already shown the status of occupational safety management either the facilities or the equipment being operated. Management commitment and supports in 2003 needs an improvement in the inspection program monitoring, training and workers from drilling industry contractors to perform inspection along with the inspection team. The low quality results in the implementation of occupational safety inspection at drilling industry 2003-2004 is due to the lack of monitoring, supervisor's knowledge of improvement completion. The very good result shown at drilling rig from 2003 until 2005 is because the drilling contractor has performed internal inspection, already has an authorization letter to perform operation (SILO) and the management has done better monitoring, workers involvement has improved and monitoring and evaluation is well-performed.
