What OSHA 10 Module 6 Actually Covers
The Crane and Derrick training module is part of the broader OSHA 10-hour outreach program for construction. Module 6 specifically addresses cranes, derricks, lifting equipment, and the safety protocols that come with operating or working around them. The exam tests whether you understand signal procedures, load calculations, rigging basics, and the difference between what the regulation says versus what happens on a job site when things go sideways. I took this module back when the course was still distributed as PDF packets instead of online platforms, and honestly, the exam hasn't changed all that much since then. The core material still revolves around 29 CFR 1926 Subpart CC, which covers crane operations in construction. The test questions are mostly scenario-based rather than straight memorization, which trips people up if they try to cram definitions without understanding the context.

The exam itself is usually a multiple-choice test with anywhere from 20 to 40 questions depending on the training provider. Passing score typically sits at 70% or higher, though some courses require 75%. You get about 30 to 60 minutes to complete it. Time pressure isn't usually the problem — the issue is that several questions describe realistic job-site situations where more than one answer looks correct at first glance, but only one matches what the regulation actually requires. Here is one thing that surprised me when I was going through this module: the signal person requirements. Most people assume a standard hand signal is enough for everyday lifting. But under 1926.1425, if the operator cannot see the load directly, or if the lift requires precise placement, you need a certified signal person. Not just a guy on site who knows the gestures. Certified. The exam will throw in a scenario about a blind lift behind a wall, and the right answer involves a signal person, not just yelling instructions. I ran into this on an actual job when a foreman had a laborer signaling a crane load through an opening in scaffolding. The OSHA inspector stopped the work immediately. That laborer had zero certification. We rerouted the lift path to eliminate the blind zone instead of waiting for a certified person, which added about two hours to the schedule. Learning the rule before you hit the exam saves you that kind of confusion. Another area where people consistently lose points is load chart interpretation. The questions will show you a setup diagram with boom length, angle, and load radius, then ask whether the lift is within capacity. You need to know how to read the load chart correctly and understand that the rated capacity decreases as the radius increases. Many test-takers pick the answer based on the boom length alone and ignore the working radius. The correct approach always considers both variables together.
How the Training Module Is Structured
The Module 6 content breaks down into several key sections. You cover crane types and their operational differences, foundational rigging principles, lift planning requirements, inspection procedures, and emergency response. The rigging section alone can account for a significant portion of the exam questions, which is why I recommend spending extra time on wire rope inspections, sling configurations, and hitch types. A diamond hitch, a vertical hitch, and a basket hitch each distribute load differently, and the exam expects you to know which configuration applies to which scenario. The lift planning portion is where the module gets practical. You learn about pre-lift meetings, the role of the competent person, and when a lift qualifies as critical. A critical lift under OSHA definition includes anything over 75% of the crane's rated capacity, unknown ground conditions, multi-crane lifts, or tandem lifts. If a question describes a scenario that fits any of these criteria, the answer almost always involves a detailed written lift plan and a competent person supervising the operation. One counter-intuitive point that beginners miss: the competent person does not need to be the crane operator. In fact, keeping those roles separate is often safer because the operator is focused on the machine while the competent person evaluates the overall setup, ground conditions, and exclusion zones. The exam sometimes frames this distinction in a way that makes you think the operator should also be the competent person, but that is not the standard. These are two different roles with different responsibilities.

Common Pitfalls on the Exam
The biggest mistake I see candidates make is treating the exam like a recall test instead of an application test. They memorize the OSHA numbers and percentages but struggle when a question puts them in a real situation. For example, knowing that the minimum safe distance from overhead power lines is 10 feet for lines up to 50 kV is useful, but the exam might describe a scenario where the lines are de-energized and grounded, which changes the requirement entirely. You have to read the full scenario, not just scan for keywords. Another trap involves the terminology. OSHA uses specific terms like "competent person," "qualified person," and "designated person," and they mean different things. A competent person can identify hazards and has authority to correct them. A qualified person has formal certification or extensive knowledge in a specific area, like lift planning or rigging design. Mixing these up on the exam will cost you points. I once saw someone confidently choose an answer about a competent person inspecting rigging, when the regulation actually requires a qualified person for certain rigging inspections. The distinction matters in the real world too, not just on the test.
What the Exam Does Not Cover Well
I want to be straightforward about the limitations of this module. The OSHA 10-hour course gives you awareness-level training. It will not prepare you to operate a crane. It will not teach you advanced load dynamics, complex lift engineering, or the kind of site-specific planning that experienced crane operators and lift directors handle daily. If you are looking for operational certification, you need separate credentials through organizations like NCCCO, and you need hands-on training that this course does not provide. The exam questions also tend to simplify ground conditions. In the real world, soil bearing capacity varies across a site, and outrigger pad placement depends on multiple factors including moisture content, compaction, and proximity to excavations. The test might present a single soil type for the entire site, which is rarely accurate on an actual job. If you are using this training for field work, supplement it with a geotechnical report or at least a proper ground condition assessment before any lift.
Study Approach That Actually Works
Rather than re-reading the entire module packet multiple times, focus on understanding the scenarios behind each rule. When you encounter a regulation about swing radius clearance, visualize what happens when the load starts rotating and the radius encroaches on a pedestrian zone. The regulation exists because of real incidents. Connecting the rule to the consequence makes it stick better than rote memorization. Practice with sample questions if your course provider offers them. Work through each one and explain out loud why the correct answer is right and why each wrong answer is wrong. This forces you to engage with the material at a deeper level. I did this for the rigging section and caught a pattern where the exam consistently tests the difference between a safe working load and the breaking strength of slings. Understanding that working load limit includes a safety factor built into the breaking strength is the key to answering those questions correctly. Download materials from your course provider's portal before the exam so you are not hunting for resources during the test window. Most providers allow open-book testing, but you still need to know where to find information quickly. I keep a bookmarked list of the load chart reading guide and the signal person certification requirements from my module packet. When I see a question about signal communication, I go straight to that section instead of scrolling through everything.
Final Notes
The OSHA 10 Module 6 Cranes Exam is passable with focused study if you treat it as a practical assessment rather than a trivia quiz. The content matters on the job site more than most people realize. A solid grasp of rigging fundamentals, signal procedures, and load chart reading can prevent serious incidents. The training does its best within the scope of a ten-hour course, but it is not comprehensive. Pair it with on-the-job mentorship and formal certification programs if crane operation is part of your role.
