Construction Safety Quiz
Questions: 16 · 10 minutes
1. A crane is moving a suspended load across part of the site. Where should workers position themselves?
Outside the load's path and never directly beneath it
Under the load briefly if they maintain visual contact with it
Close to the load so they can steady it by hand if it swings
Anywhere outside the crane operator's cab-side blind spot
2. Before maintenance begins on a machine, what does an effective energy-isolation process include?
Switching the control button off and telling nearby workers not to restart it
Isolating energy sources, applying controls, addressing stored energy, and verifying isolation
Unplugging one power source without checking for stored or secondary energy
Leaving the machine running until its fuel or pressure is completely exhausted
3. While climbing a portable ladder, which practice provides the most stable body position?
Carry light tools in one hand and grip the ladder with the other
Lean sideways rather than climb down to reposition the ladder
Face the ladder and maintain three points of contact
Climb facing outward when descending for a clearer view below
4. After heavy rain, workers are scheduled to re-enter an excavation. What should happen first?
Pump out visible water while workers begin preparing the trench
Check only the access ladder because the trench was safe yesterday
Have the excavation reassessed by the designated competent person
Let one worker enter briefly to look for new cracks in the soil
5. You find an extension cord with exposed internal wires. What is the safest immediate response?
Wrap the damaged area with ordinary tape and finish the task
Move the damaged section away from wet or high-traffic areas
Use it only for tools that draw relatively little power
Remove it from service, identify it as defective, and report it
6. What is the appropriate way to reach a scaffold work platform?
Climb the outside frame while maintaining three points of contact
Step across from a nearby structure when the gap appears manageable
Climb the cross-bracing if the platform is only one level above
Use the scaffold's designated ladder, stairway, or access system
7. A task will cut concrete and generate respirable silica dust. Which control should be prioritized?
Schedule the cutting near the end of the shift
Have workers stand upwind whenever the wind direction is favorable
Rely on disposable dust masks without changing the cutting process
Use suitable wet-cutting or local exhaust controls for the task
8. Before entering a permit-required confined space, what is a key safety step?
Follow the entry procedure, including appropriate atmospheric testing and required controls
Enter briefly without equipment to determine whether the air smells normal
Rely on a coworker outside the space to notice early symptoms
Open the access cover for a few minutes and assume natural ventilation is sufficient
9. Materials and debris are blocking a frequently used walkway. What should the crew do?
Leave the obstruction in place if experienced workers know about it
Clear the route or establish a properly controlled alternative path
Step over the debris until the scheduled end-of-day cleanup
Add a small warning marker while continuing to use the walkway
10. What information is a Safety Data Sheet primarily intended to provide?
A supplier's recommended retail price and ordering information
A record of which employees have used a chemical during each shift
A chemical's hazards, safe handling guidance, and emergency measures
A guarantee that normal use of the chemical requires no additional controls
11. A hard hat receives a significant impact from a falling object, but no crack is visible. What should happen?
Continue using it because visible damage is the only reason for replacement
Use it only for tasks where falling objects are considered unlikely
Remove it from service and replace it according to the applicable guidance
Press on the shell to test it, then return it to use if it feels rigid
12. A coworker collapses in an area where an unknown gas may be present. What is the best initial response?
Enter immediately while holding your breath and drag the worker out
Raise the alarm, keep others out, and activate the site's trained emergency response
Wait nearby to see whether the worker recovers without assistance
Send the nearest coworker in while someone searches for respiratory protection
13. A worker needs to move a heavy, awkward object. Which plan best reduces manual-handling risk?
Assess the load and route, then use mechanical help or a team lift when appropriate
Hold the object away from the body to improve visibility
Twist at the waist so the feet can remain firmly planted
Lift quickly before muscle fatigue has time to develop
14. A crew must work beside an unprotected floor opening. Which measure best controls the fall hazard?
Mark the opening with bright paint so it is easier to notice
Install a suitable cover or guardrail system before work begins
Ask workers to approach the opening only when necessary
Place materials around the opening to create a visible boundary
15. In the hierarchy of controls, which approach is generally most effective?
Rotate workers to reduce each person's exposure time
Provide personal protective equipment for everyone exposed
Post warning signs near the hazard
Eliminate the hazard so workers are no longer exposed to it
16. A power tool must be used in a damp construction area. What is the best approach?
Use inspected equipment with a suitable protected supply, such as GFCI/RCD protection
Wear dry gloves so an ordinary electrical supply becomes acceptable
Connect the tool through multiple extension cords to increase distance from moisture
Run the tool intermittently so electrical components have time to cool
