SAFETY WORK CYCLE SIKLUS HARIAN K3L - Morning Assembly - Kiken Yochi Meeting - Pre- operation Inspection - HSE Induction - Daily Patrol - Daily permit to Work - JSA MORNING ASSEMBLY & CHECK PPE dilakukan setiap shift kerja. Supervisor/ Pelaksana memaparkan rencana kerja, potensi bahaya dan pengendaliannya. Safety Officer menyampaikan temuan Daily Patrol kemarin dan tindakan perbaikannya. KIKEN YOCHI MEETING Ada 3 level KY Meeting (TBM) 1. Supervisor / SO berbicara di tengah lingkaran, menyampaikan potensi bahaya dari pekerjaan yang akan dilakukan secara umum 2. Dalam 1 lingkaran (max. 20 orang), Leader (bisa Spv atau Foreman), menunjuk random anggotanya, pekerja yang ditunjuk harus bisa menyampaikan : pekerjaan yang akan dia dilakukan, material dan alat yang akan digunakan, bahaya dari pekerjaan dan pengendaliannya 3. Memberi tepukan psikologis dan membuat Laporan KYM dan Leader mengisi Papan KYM
SAFETY WORK CYCLE SIKLUS MINGGUAN K3L - Safety Talk - General Cleaning - Joint Weekly Site Patrol & Meeting - Blood Pressure Checking - Weekly Inspection SAFETY TALK Bentuk kegiatan hampir sama dengan morning assembly, ditambah dengan penyampaian terkait pencapaian kinerja K3L, safety alert dan isu K3L. Bertujuan menumbuhkan kesadaran pekerja untuk turut mencapai target K3L proyek Weekly Patrol Weekly Meeting Blood Pressure Checking Weekly Inspection SIKLUS BULANAN DAN TAHUNAN K3L - Safety Campaign - Medical Check Up - Emergency Drill - Color Coding Inspection - P2K3 Inspection & Meeting - Management Tour SAFETY CAMPAIGN REWARD
CONTROL SAFETY CROSS INSPECTION Patrol dan Inspeksi K3L di salah satu proyek yang dihadiri oleh perwakilan HSE Coordinator / HSE Manager proyek lainnya HSE PRE CONSTRUCTION MEETING Membahas control dari method yang akan dilaksanakan, dihadiri oleh PM, Spv, dan HSE proyek lain. Bisa dilaksanakan beberapa kali sesuai progress CSMS dan KICK OF MEETING SUBKONTRAKTOR Menyampaikan persyaratan kerja di Kajima Workplace Measurement Emergency Drill Weekly dan Monthly Inspection Lifting equipment

CRITICAL LIFTING Kriteria Umum Critical Lifting: 1. Total beban yg diangkat melebihi ambang batas standar. Contoh angkatan > 80% dari SWL load chart. 2. Pengangkatan orang 3. Material khusus/ Abnormal Size 4. Pengangkatan menggunakan dua crane atau lebih 5. Pengangkatan material yg khusus, mudah rusak, dan bila rusak tidak bisa diperbaiki, mengganggu proses kerja, dll. 6. Pengangkatan material yg akan dibongkar/demolish, ketidaktahuan berat beban yg akan diangkat 7. Pengangkatan di area power lines, over active work areas, occupied buildings, public roadways, transportation systems, etc. 8. Operasional pengangkatan di area terbatas (confined space), keterbatasan ketinggian boom, dll. ALUR KERJA UNTUK AKTIVITAS CRITICAL LIFTING Critical Lifting LIFTING PLAN (diperiksa oleh Safety Engineer) lifting plan approval oleh Top Site Management Pre-lifting meeting (Precons & Training) *Safety Engineering melakukan review pada lifting plan yang diajukan, memastikan lifting plan memenuhi standar atau merekomendasikan standar adopsi standar baru jika perusahaan/ proyek yang bersangkutan belum memiliki acuan terkait pekerjaan baru/ abnormal activity
