Lead the permitting process for high-hazard tasks (Confined Space Entry, Hot Work Permits, LOTO/energization). Monitor subcontractor compliance; stop work immediately if unsafe conditions are observed. Site inspection and audit.
• Incident Management & Investigation Manage the incident reporting system (near-misses, first aid, recordables). Conduct thorough root-cause investigations for any safety incidents. Track corrective actions to closure and ensure lessons learned are shared across the project team.
• Training & Induction Develop and deliver site-specific safety orientations for all new personnel (including GC, MEP, and security staff). Facilitate toolbox talks (TBT) on critical topics such as arc flash prevention, fall protection, and heat stress management. Ensure all workers possess valid qualifications (e.g., WAH certification, forklift licenses).
• Environmental Compliance Monitor environmental controls related to erosion, sediment control, and stormwater management (SWPPP). Oversee waste management protocols, ensuring proper segregation and disposal of hazardous materials (oil, batteries, chemicals).
