    points and
    performance report

    HL D&I Halla. selects key safety management target points on a monthly basis and offers intensive management on them by sites and reports performance results to the headquarters for feedback

  • Permit-to-Work
    System (PTW)

    The PTW system refers to a system in which accident-prone or hazardous/dangerous types of construction are selected in advance and supervisors from subcontractors for those projects are required to establish safety plans and receive permission from the project manager and safety manager prior to commencement of work. This system enhances safety awareness of supervisors from subcontractors and encourages their voluntary participation.
