OSHA 10 common mistakes
OSHA 10 · Understand the traps and how to avoid them.
Treating the 10-hour course as certification prep and memorizing trivia instead of learning the legal duty framework, then missing questions about employer vs. employee responsibilities.
Candidates assume OSHA 10 is a license exam with pass/fail stakes and over-focus on dates and numbers, while the course actually tests understanding of the OSH Act's division of duties.
What to do instead
Before studying, write out the two-column split: employer duties (provide a workplace free of recognized hazards, comply with standards, training, recordkeeping) vs. employee duties (comply with standards, report hazards, use PPE). Test yourself by sorting scenarios into the correct column.
Confusing the General Duty Clause with a specific standard and selecting it as the answer whenever a hazard appears in a scenario.
The General Duty Clause is the most memorable phrase in the introduction material, so it becomes a default answer even when a specific standard (fall protection, scaffolding, excavation) clearly applies.
What to do instead
Adopt a rule: if the scenario names a specific activity covered by a standard, the specific standard wins. Reserve Section 5(a)(1) for hazards with no applicable specific standard. Practice by labeling ten scenarios 'specific standard' or 'General Duty Clause' and stating why.
Mixing up the inspection and citation process, such as assuming employers must be given advance notice of an inspection or that a citation must be issued before abatement can be required.
The procedural material is presented as a list of steps and candidates skim it, retaining only fragments like 'walkaround' and 'penalty' without the order or the rights attached to each step.
What to do instead
Build a one-page timeline: inspection priorities, warrant/consent, opening conference, walkaround with employee representative, closing conference, citation issuance, abatement period, contest window. Annotate each step with who holds the right (employer, employee, compliance officer).
Misidentifying which of the Focus Four hazards caused a described fatality, particularly labeling a struck-by incident as caught-in/between or vice versa.
The four categories overlap in real narratives-a falling object that pins a worker, or a wall collapse that hits someone-and candidates classify by the injury rather than by the mechanism of energy transfer.
What to do instead
Memorize the mechanism definitions: struck-by means force from an object in motion hitting the worker; caught-in/between means the worker is squeezed or crushed between or inside objects. Classify by asking 'was the worker hit, or was the worker trapped?' Then drill mixed scenarios and justify each label in one sentence.
Applying the wrong fall protection trigger height, such as using the 6-foot general construction threshold for steel erection, scaffolding, or excavations.
The 6-foot number is taught first and repeated most often, so it crowds out the exceptions that appear in scenario questions.
What to do instead
Create a trigger-height table covering general construction, scaffolds, steel erection, excavations, and ladders, and note the controlling condition for each. Review the table before each practice set rather than relying on a single remembered number.
Selecting administrative controls or PPE as the primary fix for a Focus Four hazard when an engineering control or elimination was available.
PPE is the most visible and familiar answer, and candidates default to 'wear the right equipment' without applying the hierarchy of controls.
What to do instead
For every hazard scenario, rank all four control levels before choosing. Practice writing the highest-level feasible control first (eliminate the fall exposure, guard the edge, then harness). If your answer is PPE, justify why higher controls are infeasible.
Treating the 'Other Training Resources' domain as filler and skipping the distinction between required training, voluntary training, and outreach awareness courses.
Candidates prioritize the Focus Four and assume the resources domain is not testable, so they never learn what OSHA 10 does and does not certify.
What to do instead
Write a short comparison of what each resource provides (outreach courses, publications, consultation services, training institute) and explicitly note that the 10-hour card is awareness training, not a certification or license. Review this before the exam.
Answering Spanish-language resource questions as if translated materials are optional or identical in content and availability to English materials.
Candidates who work only in English skim this domain and assume it is a note about translation rather than a set of testable facts about training and communication obligations.
What to do instead
Study the training standard's requirement that instruction be delivered in a language and vocabulary the worker understands, then list which OSHA resources exist in Spanish. Frame each fact as 'what the employer must ensure' rather than 'what translation exists.'
Treating the Course Presentations domain as passive review, watching or skimming slides without extracting the specific values, definitions, and hazard controls each module is designed to test.
Presentation content feels like background narrative, so candidates read for flow instead of mining each slide for the one testable fact it contains.
What to do instead
Convert each presentation module into a question set as you go: one definition, one number, one control per slide. Answer them closed-book afterward and revisit only the modules where recall failed.
Confusing recordkeeping and reporting obligations, such as the timeframe for reporting a fatality versus the timeframe for reporting an amputation or in-patient hospitalization, or assuming all injuries must be recorded.
Multiple reporting clocks and recording criteria are taught close together, and candidates collapse them into a single 'report serious injuries promptly' rule.
What to do instead
Build a two-column reference: report to OSHA (fatality within 8 hours; amputation, loss of an eye, or in-patient hospitalization within 24 hours) versus record on the OSHA log (recordability criteria). Add a note that reporting and recording are separate duties, then self-quiz on mixed timelines.
