What the domains mean in practice

  • Hazard and risk identification and control (36.6%): the common construction hazards and their controls, from falls and excavations to health exposures, plus how to apply a hierarchy of controls and build a job hazard analysis.
  • Safety program development, implementation and sustainment (22.5%): inspections, competent persons, planning, measuring safety performance and keeping a program current.
  • Leadership, communication and training (21%): training workers, running short crew talks, and leading so people speak up.
  • Emergency preparedness, incident investigation and response (19.9%): emergency action plans, fire protection, first aid, incident command and finding root causes.
