When should identified hazard controls be implemented?

• A. After an incident
• B. Before starting any work and as new hazards arise
• C. Only during risk assessments
• D. After completion of work

Answer: (B)

Hazard controls should be implemented before starting work and updated whenever new hazards are identified during the job. This proactive approach means you plan and apply the necessary controls during planning and kickoff, then adapt them as conditions change or new dangers are found. It’s about preventing harm rather than reacting after something goes wrong, which aligns with the idea of reducing risk to an acceptable level from the outset and throughout the task. If you wait until after an incident to act, harm has already occurred. If you limit controls to the risk assessment phase, you miss real-time changes that can emerge once work begins. If you only address hazards after the work is finished, risks are left unmanaged during execution. By implementing and updating controls continuously, you use the full range of protective measures—engineering and administrative controls, along with PPE—as needed to keep people safe.
