Question 1

The 'stability triangle' concept helps operators recognize the hazard of:

Accepted Answer

Understanding the stability triangle allows operators to visualize how speed, load position, and turning affect the center of gravity, helping them prevent tip-over accidents.

Question 2

A 'pinch point' hazard exists:

Accepted Answer

The moving parts of the mast create severe shearing/crushing hazards. Never put hands or feet through the mast uprights.

Question 3

Operating a forklift on a dock with a slippery floor (oil/ice) creates a hazard of:

Accepted Answer

Reduced traction creates loss of braking and steering control, which is deadly near dock edges.

Question 4

Overhead clearance hazards include:

Accepted Answer

Striking overhead objects can cause structural collapse, fire (sprinklers), or electrocution.

Question 5

A 'blind corner' is hazardous because:

Accepted Answer

Blind spots are primary collision zones. Operators must stop, look, and honk.

Question 6

Carbon Monoxide (CO) poisoning is a risk when using:

Accepted Answer

IC engines produce CO exhaust. Without adequate ventilation, this colorless, odorless gas can kill.

Question 7

Loose items on the floor (wood, plastic wrap) can cause:

Accepted Answer

Debris breaks the friction between the tire and floor, leading to loss of control.

Question 8

If a load is stacked too high or loosely:

Accepted Answer

Unstable stacks can collapse on the operator or pedestrians. Loads must be stable and secure.

Question 9

Trailer creep (dock walk) occurs when:

Accepted Answer

The momentum of the forklift entering can push the trailer forward, creating a gap that the forklift can fall through. Wheel chocks prevent this.

Question 10

The 'fulcrum' of the forklift creates a hazard of:

Accepted Answer

Because the front wheels act as a fulcrum, exceeding capacity causes the rear of the truck to lift, leading to loss of steering and tipping.

Question 11

Battery acid contact with eyes is a hazard that requires:

Accepted Answer

Sulfuric acid causes permanent blindness quickly. Immediate flushing is the only first aid.

Question 12

Operating near the edge of a loading dock is dangerous because:

Accepted Answer

A moment of distraction can lead to driving off the edge, usually resulting in a tip-over and severe injury.

Question 13

Hydraulic injection injury occurs when:

Accepted Answer

Pinhead leaks in high-pressure lines can inject fluid into tissue, requiring immediate surgical removal to prevent gangrene.

Question 14

Refueling a hot engine creates a hazard of:

Accepted Answer

Fuel vapors can ignite on hot manifolds or electrical sparks.

Question 15

Wearing loose clothing or jewelry while operating is a hazard because:

Accepted Answer

Snag hazards can pull the operator into machinery or inadvertently activate controls.

Question 16

A 'High Heat' hazard exists when:

Accepted Answer

Paper/lint buildup on the radiator can cause overheating and potential fire.

Question 17

Noise levels in a warehouse can mask:

Accepted Answer

High ambient noise reduces the effectiveness of audible warnings, requiring increased visual vigilance.

Question 18

Carrying a load that exceeds the backrest height creates a hazard of:

Accepted Answer

Unsecured loads above the backrest can tumble onto the operator's head.

Question 19

What is the hazard of 'Bridging'?

Accepted Answer

If the dock plate isn't sufficient, the forklift can fall into the gap.

Question 20

Improperly stacked pallets present a hazard of:

Accepted Answer

Leaning or broken pallets can collapse unpredictably.

Question 21

When entering a dark trailer, the hazard is:

Accepted Answer

Auxiliary lighting (dock lights or truck lights) is required to see hazards inside trailers.

Question 22

If a forklift tire blows out (pneumatic):

Accepted Answer

Sudden loss of tire pressure destabilizes the stability triangle instantly.

Question 23

Static electricity discharge during refueling can cause:

Accepted Answer

A spark near fuel vapors causes ignition.

Question 24

Pedestrians wearing headphones present a hazard because:

Accepted Answer

Auditory isolation makes them unaware of approaching equipment.

Question 25

Operating a forklift with a propane leak in a confined space creates:

Accepted Answer

Propane pools in low areas and is highly explosive if ignited.

Question 26

Why is 'free rigging' (sling on forks) hazardous?

Accepted Answer

Rigging directly to fork tines is unstable; the sling can slide off. Proper attachments (hooks) should be used.

Question 27

Using a forklift to open a door by bumping it poses a hazard of:

Accepted Answer

Violent impact stresses the mast and can dislodge the door onto the truck.

Question 28

The hazard of 'off-center loading' is:

Accepted Answer

Side-heavy loads shift the CG sideways toward the edge of the stability triangle.

Question 29

Sun glare when exiting a building creates a hazard of:

Accepted Answer

Sudden lighting changes (dark to bright) blind the operator momentarily.

Question 30

Accumulation of paper or trash on the floor is a hazard because:

Accepted Answer

Debris is a traction hazard and a fire hazard if sucked into engine fans/exhausts.
