Fall Protection and Scaffold Training questions for the CHST

Question 1

A roofing crew has current written fall protection training certifications. All of their training covered guardrail systems, which they have used for months. The contractor now switches the job to personal fall arrest systems with rope-grab lifelines, which none of the crew has used. The crew's supervisor wants them on the roof tomorrow. What must the employer do?

1. AKeep the existing certifications on file, because the training records are current and the crew is already certified
2. BRetrain the affected workers on the new system, because the change in fall protection equipment makes their earlier training obsolete
3. CWait until a worker shows unsafe use of the new equipment, and retrain only that worker
4. DHave the supervisor give a brief verbal explanation at the start of the shift and update the certification date

Question 2

A crew of laborers will work from a supported scaffold set up beside a building, with energized overhead power lines running near the work area. A qualified person trained them on proper use of the scaffold, handling materials on the platform, and fall hazards. Electrical hazards were not discussed. The superintendent says the training is complete because a qualified person delivered it. What does the standard require here?

1. AOnly the employees who erect and dismantle the scaffold need electrical hazard training
2. BThe training must also cover the nature of the electrical hazards in the work area, since the power lines are present
3. CThe laborers need no further training until a near miss involving the power lines occurs
4. DThe training is adequate, because a qualified trainer covering fall hazards and scaffold use satisfies the requirement
