Employers involved in culvert construction must address the risks of reinforcement bar (reo bar) collapses. A recent incident highlighted the need for proper controls to prevent serious injuries when reo bar cages collapsed during installation.

Key Points

  • Hazards Identified: Reo bar structures, if not adequately supported, can collapse, posing risks to workers nearby.
  • Contributing Factors: Failures included insufficient bracing, poor stability of ground surfaces, and inadequate controls during reo bar installation.
  • Legal Duties: Employers must comply with OHS Regulations by identifying hazards and implementing risk control measures to ensure worker safety.

Safety Tips

  • Develop and implement a safe work method statement (SWMS) for all high-risk construction work, including reo bar installation.
  • Ensure adequate bracing and propping of reinforcement structures during all stages of construction.
  • Conduct geotechnical assessments to ensure stable ground conditions.
  • Supervise work closely to ensure compliance with safety procedures.
  • Regularly inspect temporary supports and adjust as required to maintain structural integrity.

Employer Responsibilities

  • Identify hazards associated with reinforcement bar installation and assess the risk of collapse.
  • Provide adequate training, instruction, and supervision to workers involved in the task.
  • Use a hierarchy of control to minimize risks, including physical safeguards such as bracing and barriers.
  • Monitor and review safety controls to ensure effectiveness throughout the project.

Employee Responsibilities

  • Follow all workplace safety procedures for installing and working near reo bars.
  • Wear personal protective equipment (PPE) as required.
  • Report any concerns about stability or hazards to supervisors immediately.
  • Participate in safety training and follow SWMS for high-risk construction tasks.

By implementing these controls and following safety procedures, employers and workers can reduce the risk of injuries during culvert construction involving reinforcement bars.
