Free OSHA 30-Hour General Industry Study Companion — 29 CFR 1910 practice questions (2026)

What is the format? These ten original multiple-choice questions introduce OSHA 30-Hour General Industry Study Companion — 29 CFR 1910 study topics. They are practice material, not actual exam items. Not authorized OSHA Outreach training. Does not issue an OSHA card. Cards come only from OSHA-authorized trainers after 30 instructional hours.

What does this prepare me for? Workplace hazard-recognition study, not authorized Outreach training or an OSHA card.

What should I study? Start with introduction to osha, walking-working surfaces, and exit routes, hazard communication, ppe, and electrical, machine guarding, lockout/tagout, and materials handling. This bank uses 29 CFR 1910. Check the current exam objectives, adopted editions, and permitted references before planning your study.

How should I practice? Choose an answer before opening the explanation. Read the cited reference and revisit unfamiliar topics. These samples are general preparation, not jurisdiction-specific advice.

1 / Introduction to OSHA, walking-working surfaces, and exit routes

A new warehouse employee receives safety instructions in a language they cannot understand. Which worker-rights principle should guide the employer's response?

  1. Require the worker to infer hazards from equipment color
  2. Treat a signature as proof of understanding regardless of language
  3. Provide safety and health training in a language the worker understands
  4. Wait until an injury to explain the hazards
Show answer & explanation

Provide safety and health training in a language the worker understands

OSHA's worker-rights guidance identifies understandable safety and health training as a worker right.

2 / Introduction to OSHA, walking-working surfaces, and exit routes

A warehouse lead wants broader hazard-awareness study than an introductory worker course. Which audience does OSHA identify as especially suited to 30-hour Outreach classes?

  1. Only prospective OSHA inspectors
  2. Only licensed electricians
  3. Supervisors or workers with some safety responsibility
  4. Only workers who have already been injured
Show answer & explanation

Supervisors or workers with some safety responsibility

The Outreach FAQ distinguishes basic 10-hour worker awareness from the greater depth of the 30-hour class for supervisors and workers with safety responsibilities.

3 / Introduction to OSHA, walking-working surfaces, and exit routes

An inspection finds loose waste scattered through a storeroom passageway. Which basic walking-working-surface condition is required?

  1. Housekeeping only after a recorded injury
  2. A clean, orderly and sanitary condition
  3. Cleanliness only in customer areas
  4. No requirements for storerooms
Show answer & explanation

A clean, orderly and sanitary condition

The surface rule expressly covers passageways and storerooms as well as work areas. Housekeeping prevents hazards before someone is injured.

29 CFR §1910.22(a)(1)

4 / Introduction to OSHA, walking-working surfaces, and exit routes

A floor opening presents a stepping-through hazard but the lower level is only 2 feet below. Does being below 4 feet eliminate protection?

  1. No; covers or guardrails are required for the stepping or tripping hazard
  2. Yes; all hole protection begins only at 4 feet
  3. Yes; only rooftop openings require covers
  4. No; a warning sign alone is always the required system
Show answer & explanation

No; covers or guardrails are required for the stepping or tripping hazard

The hole rule separately addresses stepping or tripping into holes less than four feet above a lower level. The general fall-height threshold is not a universal exemption.

29 CFR §1910.28(b)(3)(ii)

5 / Introduction to OSHA, walking-working surfaces, and exit routes

A designer uses a 28-inch exit access and assumes it is adequate for any number of occupants. What additional criterion must be checked?

  1. The 28-inch minimum automatically covers every occupant load
  2. Only the length of the route matters
  3. Only employees carrying tools count toward capacity
  4. Width must also accommodate the maximum permitted occupant load
Show answer & explanation

Width must also accommodate the maximum permitted occupant load

Twenty-eight inches is a minimum exit-access width, not a universal occupant-capacity approval. The route must also accommodate the permitted load.

29 CFR §1910.36(g)(2); 1910.36(g)(3)

6 / Hazard communication, PPE, and electrical

An employee brings personally owned protective equipment to the plant. Who remains responsible for assuring its adequacy, maintenance and sanitation?

  1. Only the retailer
  2. Only the employee's previous employer
  3. No one because ownership makes PPE exempt
  4. The employer
Show answer & explanation

The employer

Employee ownership does not remove the employer's duty to assure that equipment is adequate and properly maintained and sanitary.

29 CFR §1910.132(b)

7 / Hazard communication, PPE, and electrical

After supply isolation, capacitors still contain electrical energy that could endanger personnel. What does the electrical rule require?

  1. Treat the equipment as safe after its indicator light goes dark
  2. Release the hazardous stored electrical energy using the required precautions
  3. Assume the open supply switch discharged them
  4. Leave the energy because it is not utility power
Show answer & explanation

Release the hazardous stored electrical energy using the required precautions

Stored electrical energy can remain after source disconnection. The rule requires discharge and specified short-circuiting and grounding of high-capacitance elements where that energy could endanger personnel.

29 CFR §1910.333(b)(2)(ii)(C)

8 / Hazard communication, PPE, and electrical

An employee's unprotected 8-hour TWA is 88 dBA. May claimed earplug attenuation be subtracted to exclude the worker from the hearing-conservation program?

  1. Yes; any earplug makes program coverage optional
  2. No; the program begins only at 100 dBA
  3. Yes; only sound measured inside the earplug counts
  4. No; program exposure is computed without PPE attenuation
Show answer & explanation

No; program exposure is computed without PPE attenuation

Program inclusion uses exposure without credit for PPE attenuation. Hearing protectors do not erase the employer's monitoring, testing and training obligations.

29 CFR §1910.95(c)(1)

9 / Machine guarding, lockout/tagout, and materials handling

What personal identification must a lockout or tagout device provide?

  1. Only the lock's purchase price
  2. Only the date the plant opened
  3. Only the equipment seller's name
  4. The identity of the employee applying it
Show answer & explanation

The identity of the employee applying it

Devices must identify the applying employee. This supports accountability and safe coordination of energy control.

29 CFR §1910.147(c)(5)(ii)(D)

10 / Machine guarding, lockout/tagout, and materials handling

May a worker walk beneath raised forklift forks when they carry no load?

  1. Yes; if the operator sounds the horn
  2. No; no person may stand or pass beneath the elevated portion, loaded or empty
  3. Yes; if the worker walks quickly
  4. Yes; empty forks cannot create a hazard
Show answer & explanation

No; no person may stand or pass beneath the elevated portion, loaded or empty

The prohibition applies whether the elevated portion is loaded or empty. Removing the load does not remove the hazard from the raised equipment.

29 CFR §1910.178(m)(2)
