All safety rules are written in blood

SEMAKIN SERING BICARA SAFETY, SEMAKIN AMAN

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

3.Hook Weight = 1,3 Ton

Total = 6.78 Ton

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.

LIFTING PLAN (diperiksa oleh Safety Engineer)

lifting plan approval oleh Top Site Management

Pre-lifting meeting (Precons

& Training)

ALUR KERJA UNTUK AKTIVITAS CRITICAL LIFTING

*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

Sequence 6 (Superstructure ) – 2FL Beam & Slab

MAIN PROGRESS

1. INSTALL SCAFFOLDING FOR SUPPORT 2ND BEAM & SLAB

2. INSTALL FORMWORK BEAM & SLAB 2ND

3. INSTALL REINFORCEMENT BEAM & SLAB 2ND

4. CONCRETING BEAM & SLAB 2ND FLOOR
