You do both before you call a lift.<\/li>\n<li>OSHA requires a signal person when the operator cannot see the load or the travel path. A crew member can also call for one.<\/li>\n<li>A third-party card travels with you. A sign-off from your employer&#8217;s own tester works only for that employer.<\/li>\n<li>The record has to be on site, and it has to name each signal type you are cleared to use.<\/li>\n<li>The CCO written exam is <a href=\"https:\/\/www.nccco.org\/docs\/default-source\/2023-handbooks-forms\/signalperson-candidate-handbook_062323a.pdf?sfvrsn=ac04c30e_2\">60 questions in 60 minutes<\/a>. Hand signals are the biggest share, about 31 percent.<\/li>\n<li>The practical exam is <a href=\"https:\/\/www.nccco.org\/docs\/default-source\/2023-handbooks-forms\/signalperson-candidate-handbook_062323a.pdf?sfvrsn=ac04c30e_2\">30 scenarios<\/a>. There is no time limit. Most people finish in about 15 minutes.<\/li>\n<li>A CCO card lasts five years. Renewal is the practical exam again, in the 12 months before it expires. Renewal does not include a new written exam.<\/li>\n<li>A crane operator card does not cover this job. Signaling has its own test.<\/li>\n<\/ul>\n<p>You get certified as a signal person by passing two tests before you call a lift. One test is written. One is hands-on. OSHA requires that qualification. A national card is the record you can take to the next employer.<\/p>\n<p>Crane crews still need that person. In September 2026, data center construction spending was <a href=\"https:\/\/www.agc.org\/news\/2026\/11\/02\/data-centers-power-projects-buoy-construction-spending-september-other-sectors-stall-or-slide-face\">up 90 percent<\/a> from a year earlier. Private electric power spending was up 14 percent. Those jobs move loads the operator often cannot see.<\/p>\n<h2>When does a crane need a signal person?<\/h2>\n<p><a href=\"https:\/\/www.osha.gov\/laws-regs\/regulations\/standardnumber\/1926\/1926.1419\">29 CFR 1926.1419<\/a> names three cases.<\/p>\n<p>The operator cannot fully see the load&#8217;s path or the spot where it will land. The crane is traveling and the view ahead is blocked. Or the operator, or the person handling the load, decides the site needs a signal person.<\/p>\n<p>Signals can be hand, voice, audible, or a new method the employer can show works as well. Hand signals use the Standard Method. Some moves are not in that method. Then the signal person, the operator, and the lift director agree on the extra signals before the pick. The chart of hand signals must be <a href=\"https:\/\/www.osha.gov\/laws-regs\/regulations\/standardnumber\/1926\/1926.1422\">posted on the crane or posted near the hoist<\/a>.<\/p>\n<p>Only one person signals that crane at a time. Every direction is given from the operator&#8217;s point of view. If the signal drops out, the operator stops until it is back and a clear signal is given. Anyone who sees a hazard can call stop. The operator has to obey a stop.<\/p>\n<p>The hand shapes themselves are in the <a href=\"https:\/\/www.operator-school.com\/blog\/crane-hand-signals-explained-standard-signals-every-operator-should-know\/\">crane hand signals<\/a> guide. This article is about the qualification, not the chart.<\/p>\n<h2>What does OSHA require before you signal?<\/h2>\n<p><a href=\"https:\/\/www.osha.gov\/laws-regs\/regulations\/standardnumber\/1926\/1926.1428\">29 CFR 1926.1428<\/a> says the employer must make sure you are qualified before you give any signal. The word in the rule is qualified. A card is one way to show that. It is not the only way.<\/p>\n<p>You have to know the signals in use. If those are hand signals, you have to know the Standard Method. You have to use them correctly. You need a basic grasp of how the crane behaves. That means swing, stopping a load, and boom deflection when the load comes up. You also have to know the signal rules in 1926.1419 through 1926.1422 and 1926.1428.<\/p>\n<p>You show that in two tests. An oral or written test, and a practical test. Both are required.<\/p>\n<p>The employer keeps that record at the job site while you work there. The record must list each type of signal you are qualified to give. Hand signals and radio signals are separate lines on that record.<\/p>\n<p>If your later work shows you do not meet the standard, you stop signaling. You can go back only after new training and a new test.<\/p>\n<h2>Which card can you take to the next job?<\/h2>\n<p>OSHA allows two testers. The definitions are in <a href=\"https:\/\/www.ecfr.gov\/current\/title-29\/subtitle-B\/chapter-XVII\/part-1926\/subpart-CC\/section-1926.1401\">29 CFR 1926.1401<\/a>.<\/p>\n<table>\n<thead>\n<tr>\n<th style=\"background:transparent;background-color:transparent\">Path<\/th>\n<th style=\"background:transparent;background-color:transparent\">Who tests you<\/th>\n<th style=\"background:transparent;background-color:transparent\">What you can do with it<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Third party<\/td>\n<td>An independent body with the skill to judge signal persons<\/td>\n<td>The record can move with you to another employer<\/td>\n<\/tr>\n<tr>\n<td>Employer&#8217;s own tester<\/td>\n<td>A person who works for your employer<\/td>\n<td>That employer can use it.

You must be <a href=\"https:\/\/www.nccco.org\/docs\/default-source\/2023-handbooks-forms\/signalperson-candidate-handbook_062323a.pdf?sfvrsn=ac04c30e_2\">at least 18<\/a>. You pass a written exam and a practical exam, in either order. You follow the CCO substance abuse policy and the signalperson code of ethics.<\/p>\n<p>You have 12 months after the first passing exam to pass the other one. A request for more time is usually turned down unless the reason is extreme.<\/p>\n<p>An employer sign-off can be legal on that company&#8217;s job. It dies when you leave. If you want a card you can show the next superintendent, take the third-party route. <a href=\"https:\/\/www.operator-school.com\/rigging_signalperson_training.php\">Signalperson training<\/a> at ATS is built around that test, on the Sun Prairie yard.<\/p>\n<h2>What is on the written exam?<\/h2>\n<p>The CCO Signalperson Written Examination is 60 multiple-choice questions. You get 60 minutes. These shares are from the <a href=\"https:\/\/www.nccco.org\/docs\/default-source\/2023-handbooks-forms\/signalperson-candidate-handbook_062323a.pdf?sfvrsn=ac04c30e_2\">June 2023 candidate handbook<\/a>.

You have to stay where the operator can see you. You also have to act if the operator is not following you.<\/p>\n<p>Crane knowledge is the part people skip. The test asks how the crane reacts under a load. That includes boom deflection, a hoist line that is not vertical, drift, and side loading. It also covers two-blocking and keeping people out of the fall zone. The load&#8217;s size, shape, weight, and center of gravity are on there too.<\/p>\n<p>The rules section covers current OSHA and ASME standards. It includes <a href=\"https:\/\/www.operator-school.com\/blog\/crane-power-line-clearance-the-distances-osha-requires\/\">power line clearance<\/a>, personnel platforms, and a lift with more than one crane.<\/p>\n<p>The passing score is set in advance. You are not graded against the other people in the room. A fail comes back as pass or fail, plus a note on which topics were weak. If you fail the written exam, you wait at least four weeks before you take that same exam again. You reapply and pay the retest fee.<\/p>\n<p>CCO does not print the fee in the handbook. The fee page is on the CCO site, and it can change.<\/p>\n<h2>What is on the practical exam?<\/h2>\n<p>The practical exam checks hand signals and voice commands. It also checks that you understand crane movement under OSHA Subpart CC.<\/p>\n<p>You face 30 scenarios. There is no clock. Most candidates finish in about 15 minutes. A screen shows a picture. You give the hand signal or the voice command that matches it. You give one signal at a time, unless the command is to move slowly. A proper stop is the arm moving back and forth at least once.<\/p>\n<p>Signals follow OSHA Subpart CC. Where OSHA is silent, the proctor uses ASME B30.5 and ASME B30.3. One-handed telescoping-boom signals are an example. You lose points for a wrong signal, or for a signal that does not match those standards.<\/p>\n<p>Only you and the proctor are in the test area. The proctor records what you do. The proctor does not score you on the spot and does not review the sheet with you. CCO scores it off site. Results usually go out by email about 12 business days after CCO receives the sheet. It can take more than three weeks if the proctor batches several test days.<\/p>\n<p>Bring a current government photo ID that shows your date of birth. Bring the practical exam authorization code. Wear the PPE the site requires. That gear has to meet OSHA&#8217;s minimum.<\/p>\n<h2>How do you give a voice signal?<\/h2>\n<p>Before the lift, the operator, the signal person, and the lift director agree on the voice signals. <a href=\"https:\/\/www.osha.gov\/laws-regs\/regulations\/standardnumber\/1926\/1926.1421\">29 CFR 1926.1421<\/a> says that meeting is enough. You meet again only if someone new joins, the words get confusing, or a signal has to change.<\/p>\n<p>Each voice signal has three parts, in this order:<\/p>\n<ol>\n<li>Function and direction, such as hoist up.<\/li>\n<li>Distance, speed, or both.<\/li>\n<li>Function, then stop.<\/li>\n<\/ol>\n<p>The people on that call have to share a language they can all use.<\/p>\n<p>If the signal goes by radio or phone, <a href=\"https:\/\/www.osha.gov\/laws-regs\/regulations\/standardnumber\/1926\/1926.1420\">29 CFR 1926.1420<\/a> adds three rules. Test the radio on site before the lift. Use a dedicated channel. The operator has to hear it through a hands-free setup. A shared channel is allowed in two cases. Several cranes may share one so they can work together. A crane next to railroad tracks may share one so it can move with the trains.<\/p>\n<h2>How long does a CCO signalperson card last?<\/h2>\n<p>The card is good for five years. To keep it, you finish renewal in the 12 months before it expires. Renewal is the practical exam, the substance abuse policy, and the code of ethics. A new written exam is not part of renewal.<\/p>\n<p>Take the practical up to one year before the card expires. The new five years still starts on the old expiration date. Take it earlier than that 12-month window and the new five years start right away. You give up time on the old card.<\/p>\n<p>You can take the written and practical exams in either order the first time. After that, the practical is the one that comes back every five years.<\/p>\n<h2>Does a crane operator card cover this job?<\/h2>\n<p>Operator certification is a different rule. It covers the person in the seat. The signal rule covers the person giving directions. If you step off the crane and start signaling, 1926.1428 applies to you.<\/p>\n<p>A rigger is a different qualification too. OSHA defines a qualified rigger as a person who can solve the rigging problems on that job. <a href=\"https:\/\/www.operator-school.com\/blog\/how-to-become-a-rigger-training-certification-pay\/\">Rigger training<\/a> is worth having on a crane crew. It does not replace the signal person tests.<\/p>\n<p>The same split shows up in the seat. <a href=\"https:\/\/www.operator-school.com\/mobile_crane_training.php\">Mobile crane training<\/a> prepares you to run the crane. <a href=\"https:\/\/www.operator-school.com\/credentials.php\">NCCCO credentials<\/a> for operating and for signaling are separate cards.<\/p>\n<h2>Conclusion<\/h2>\n<p>Get the third-party card if you want work beyond one employer. OSHA will accept an in-house sign-off, and that sign-off stops at the gate. The written test is heavy on hand signals and on how the crane reacts. The practical test is short, and it grades the signal you actually give.<\/p>\n<p>ATS runs signalperson training in Sun Prairie, with the written and practical exams in view from the first day.

A CCO card is the third-party record. Your employer&#8217;s own tester can also qualify you, and that record stays with that employer.<\/p>\n<p><strong>Q: Can I use my last company&#8217;s signal person sign-off on a new job?<\/strong><br \/>\nA: Only if a third party issued it. A sign-off from the old employer&#8217;s own tester cannot be used by the new employer.<\/p>\n<p><strong>Q: How long do I have to pass both CCO exams?<\/strong><br \/>\nA: You have 12 months after you pass the first exam to pass the other one. You may take the written exam or the practical exam first.<\/p>\n<p><strong>Q: What if I fail the written exam?<\/strong><br \/>\nA: You wait at least four weeks, then you reapply and pay the retest fee. The score report tells you which topics were weak.<\/p>\n<hr \/>\n<h2>Sources<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.osha.gov\/laws-regs\/regulations\/standardnumber\/1926\/1926.1419\">OSHA: 29 CFR 1926.1419 Signals, general requirements<\/a><\/li>\n<li><a href=\"https:\/\/www.osha.gov\/laws-regs\/regulations\/standardnumber\/1926\/1926.1420\">OSHA: 29 CFR 1926.1420 Radio and telephone signals<\/a><\/li>\n<li><a href=\"https:\/\/www.osha.gov\/laws-regs\/regulations\/standardnumber\/1926\/1926.1421\">OSHA: 29 CFR 1926.1421 Voice signals<\/a><\/li>\n<li><a href=\"https:\/\/www.osha.gov\/laws-regs\/regulations\/standardnumber\/1926\/1926.1422\">OSHA: 29 CFR 1926.1422 Hand signal chart<\/a><\/li>\n<li><a href=\"https:\/\/www.osha.gov\/laws-regs\/regulations\/standardnumber\/1926\/1926.1428\">OSHA: 29 CFR 1926.1428 Signal person qualifications<\/a><\/li>\n<li><a href=\"https:\/\/www.ecfr.gov\/current\/title-29\/subtitle-B\/chapter-XVII\/part-1926\/subpart-CC\/section-1926.1401\">eCFR: 29 CFR 1926.1401 Qualified evaluator definitions<\/a><\/li>\n<li><a href=\"https:\/\/www.nccco.org\/docs\/default-source\/2023-handbooks-forms\/signalperson-candidate-handbook_062323a.pdf?sfvrsn=ac04c30e_2\">NCCCO: Signalperson Candidate Handbook, June 2023 (form 102, rev 06\/23)<\/a><\/li>\n<li><a href=\"https:\/\/www.agc.org\/news\/2026\/11\/02\/data-centers-power-projects-buoy-construction-spending-september-other-sectors-stall-or-slide-face\">AGC: September 2026 construction spending, November 2, 2026<\/a><\/li>\n<\/ul>\n<p><script type=\"application\/ld+json\">\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"Article\",\n  \"headline\": \"Certified Signal Person Training: What OSHA Requires\",\n  \"description\": \"OSHA requires a qualified signal person before anyone calls a lift.
