Jobsite Safety and Risk Mitigation
What this domain tests
Jobsite Safety and Risk Mitigation tests hazard recognition, job hazard analysis, toolbox talks, the hierarchy of controls, OSHA's Focus Four hazards, stop-work authority, and incident and near-miss reporting.
Core rules and concepts
- Apply the hierarchy of controls: eliminate the hazard, substitute a safer method, use engineering controls, then administrative controls, and use PPE as the last line of defense.
- Complete a JHA/JSA before a task: list the steps, identify hazards for each step, and assign controls.
- Hold a toolbox talk tied to the day's work, not a generic speech; record topic, date, presenter, and attendees.
- Know the Focus Four: falls, struck-by, caught-in/between, and electrical hazards.
- Every crew member has stop-work authority when a condition is unsafe.
- Report near misses as well as injuries; a near miss is free information about a control that failed.
- Inspect tools and equipment before use, keep housekeeping, and barricade hazards.
Worked example
A crew must cut a concrete slab with a gas-powered saw on a slight slope. The JHA identifies silica dust, kickback, slip/fall, noise, and fuel handling. Controls include wet cutting or dust collection, a properly rated respirator, level footing and a stable stance, hearing protection, barricades, and fueling away from ignition sources. Reasoning: the controls follow the hierarchy where feasible, and PPE is used with, not instead of, engineering and administrative controls.
Traps that cost marks
- Treating PPE as the first control.
- Assuming “no injury” means no report.
- Signing a JHA without reviewing it with the crew.
- Letting a new or transferred worker start without task-specific safety orientation.
- Ignoring housekeeping because the crew is “almost finished.”
