What could go wrong if a worker ignores a lockout/tagout procedure before servicing
equipment?
They might get seriously hurt or even killed if the machine powers on unexpectedly while
they’re working on it. Lockout/tagout is there to make sure all energy sources are shut off and
can't be turned back on.
Why would wearing loose clothing around moving machinery be a major risk?
Loose clothes can get caught in moving parts, pulling you into the equipment. That’s how
accidents like crushed hands or even amputations happen.
A scaffold doesn’t have a guardrail installed. What’s the main hazard here?
Fall risk is high. Without a guardrail, there’s nothing stopping a worker from accidentally
stepping too close to the edge and falling off.
Why is reporting near misses just as important as reporting actual injuries?
Near misses show that something unsafe almost happened. Reporting them helps fix issues
before they lead to real accidents.

What could happen if a worker removes their hard hat in an active construction zone?
If something falls from above—even a small object—it can cause a serious head injury. Hard
hats are your last line of defense.
Why is using a broken extension cord dangerous on site?
Exposed wires or damaged insulation can cause electric shocks or start fires. That’s a major
safety hazard.
What’s the danger in placing tools or materials on top of a ladder?
They can fall off and hit someone below, or shift and throw off your balance while climbing.
Bad idea either way.
Why would entering a confined space without testing the air be unsafe?
There could be toxic gases or not enough oxygen in there. Without testing, you’d have no
idea until it’s too late.
Why is eye protection a must during grinding or cutting tasks?
Sparks, metal shards, or dust can fly straight into your eyes. Safety goggles stop that from
happening.
What risk does horseplay bring to a construction site?
It distracts people and can lead to accidents. On a job site with heavy equipment and sharp
tools, messing around can get someone seriously hurt.
