OSHA Powered Industrial Truck (29 CFR 1910.178) Exam Questions & Answers 2026 (1–10)

Question 1

Under OSHA, what is the correct term for the equipment commonly called a forklift?

TheoryPractice · Accepted Answer

A powered industrial truck. OSHA standard 29 CFR 1910.178 covers these machines under the term 'powered industrial truck' (PIT), which includes forklifts, order pickers and similar trucks.

Question 2

What does the truck's nameplate (data plate) class designation, such as a 'G' marking, indicate?

TheoryPractice · Accepted Answer

The year it was built. The designation marks the power source and the classification of hazardous (combustible/flammable) locations in which the truck may be used.

Question 3

An electric forklift is generally preferred over an internal-combustion (IC) model indoors mainly because it:

TheoryPractice · Accepted Answer

Produces no engine exhaust. Electric trucks emit no combustion exhaust, avoiding carbon monoxide build-up in enclosed spaces. IC trucks require adequate ventilation indoors.

Question 4

The overhead guard on a forklift is designed primarily to:

TheoryPractice · Accepted Answer

Protect the operator from falling objects. The overhead guard protects the operator from small falling objects. It is not designed to withstand the full impact of a falling capacity load.

Question 5

What is the purpose of the load backrest extension?

TheoryPractice · Accepted Answer

To stop the load from tipping back onto the mast and operator. The load backrest extension prevents the load, or parts of it, from falling backward toward the mast and operator when the mast is tilted back or raised.

Question 6

The heavy section at the rear of a sit-down counterbalanced forklift is the:

TheoryPractice · Accepted Answer

Counterweight. The counterweight at the rear balances the load on the forks, keeping the truck stable. This is why you must never add or remove unauthorised counterweight.

Question 7

A 'tilt' control on the mast allows the operator to:

TheoryPractice · Accepted Answer

Tilt the mast forward or back to stabilise the load. Tilting the mast back cradles the load against the backrest for travel; tilting forward is used to pick up or set down a load.

Question 8

Which statement about attachments (e.g. clamps, side-shifters) is correct?

TheoryPractice · Accepted Answer

They can reduce the truck's rated capacity and must be accounted for. Attachments add weight and move the load centre, reducing rated capacity. The truck must be marked for the attachment and its derated capacity.

Question 9

An 'order picker' differs from a standard counterbalanced forklift because:

TheoryPractice · Accepted Answer

The operator platform rises with the forks and a fall-arrest harness is required. On order pickers the operator is elevated with the load, so a body harness/lanyard fall-protection system anchored to the platform is required.

Question 10

Modifications that affect capacity or safe operation of a forklift:

TheoryPractice · Accepted Answer

Require prior written approval from the manufacturer. 29 CFR 1910.178(a) requires the manufacturer's prior written approval for modifications affecting capacity or safe operation, and the data plate must be updated.
