13.1 Supervising Noncertified Applicators and Service Technicians
Key Takeaways
- 40 CFR 171.201 applies when a certified applicator allows or relies on a noncertified person to use a restricted use pesticide; the supervisor must be certified in each category of that use.
- Federal 171.201 requires 12-month pesticide-safety training (or an equivalent listed qualification), use-specific instructions the person can understand, labeling and PPE access, equipment checks, immediate communication, physical presence when the label requires it, and commercial training records kept two years.
- Oklahoma's Combined Pesticide Law requires a service technician or a certified applicator to be present at each application; an uncertified helper cannot run a 7A restaurant route alone on a radio from another county.
- A temporary certified applicator has passed the written exams but not the practical and does not qualify as the certified applicator for a license and may not act as a certified applicator; 7A, 7B, and 7C practicals are taken at OSU Stillwater within 12 months of the written exam.
- Service technician identification costs $20, is requested by the licensed employer, is issued in the licensed entity's name, and must be returned to ODAFF when employment ends; Core does not replace a category exam.
Why Supervision Is Tested on Core
Passing a Core exam does not make you a licensed pesticide business, and a Core score does not let you send anyone you like to a restaurant with a sprayer. Direct supervision is a competency the U.S. Environmental Protection Agency (EPA) writes into the commercial applicator Core standards at 40 CFR 171.103(c)(9). Candidates must know the duties in 40 CFR 171.201, the pesticide-safety training records for people who use restricted use pesticides (RUPs) under a certified applicator, the duty to give use-specific instructions, and the duty to explain Federal, State, and Tribal rules that apply to that use. Independent OpenExamPrep material for Oklahoma candidates treats 171.201 as the federal floor and then adds Oklahoma Department of Agriculture, Food, and Forestry (ODAFF) presence and credential rules that often decide the exam item.
If a restricted-use product is in the tank, federal supervision rules apply to the certified applicator who allows or relies on a noncertified person to use it. If the job is a commercial or noncommercial application in Oklahoma, a service technician or a certified applicator shall be present at each application. Those two sentences are not the same rule. A radio in another county can satisfy one piece of 171.201 (a means of immediate communication) and still leave you illegal under Oklahoma's presence rule, under a label that demands physical presence, or under both.
Who Is Who on an Oklahoma Crew
Learn the titles as legal statuses, not job nicknames on a schedule board.
A certified applicator has met Oklahoma certification standards. For commercial and noncommercial work that usually means the Core (Phase I) written exam plus at least one category (Phase II) written exam, and, in specified categories, a practical examination. The certification card is not itself a license to operate a pesticide business. A pesticide applicator license must be obtained by the certified applicator or by the employer. You supervise only in categories in which you are certified. 40 CFR 171.201(b)(1)(ii) requires the supervising certified applicator to be certified in each category applicable to the supervised pesticide use. Core knowledge does not replace a category. A person who holds only Core has not finished certification in any use category and cannot be the category supervisor for a 7A restaurant account or a 7B termite job.
A temporary certified applicator has passed the required written examinations but has not passed the practical. ODAFF currently requires a practical, in addition to Core and the category written exam, for 7A General Pest, 7B Structural Pest/Termite, and 7C Fumigation. Those practicals are conducted at Oklahoma State University in Stillwater. The practical must be completed within twelve months of passing the written examination; missing that window means retaking the written exam. Under 2 O.S. § 3-82, temporary certified applicators do not qualify as the certified applicator for a license, and they may not act as a certified applicator. A license will not be issued for a category if the applicant or representative holds only temporary certification in that category. Temporary certified applicators may qualify as a certified service technician. Until the practical is passed, treat that person as a technician-level worker, not as the person named on the business license.
A service technician is a person employed by a licensed commercial or noncommercial applicator who applies the pesticide or employs a device, but is not the certified applicator. The statutory definition itself states that a service technician or certified applicator shall be present at each application performed. The technician is certified upon passing a written service technician examination. The identification card is issued in the name of the licensed entity. The employer submits the application to ODAFF with a $20.00 issuance or renewal fee ($10.00 for a duplicate or a transfer). The licensee must return the identification to the Board when employment ends. The identification is valid for five years unless it is suspended, canceled, or revoked, recertification is required, or the technician leaves that employer. A person shall not act, do business as, or advertise as a service technician unless the identification has been issued. If a current service technician wants to become a certified applicator, the Core exam is still required; the technician exam does not substitute for Core.
A noncertified applicator, in Oklahoma's rule language (OAC 35:30-17-25), is a person who has not met the exam qualifications of a certified applicator. A nonservice technician is a person who has not met the exam qualifications of a service technician. Those helpers are not "almost technicians." OAC 35:30-17-25(b) requires a certified applicator on site to supervise any pesticide application by a non-service technician. You cannot park an uncertified helper on a 7A restaurant route and call it supervision because someone in the office is reachable by phone.
Oklahoma also sets a hard age 18 line: certified applicators, noncertified applicators, service technicians, and private applicators shall be a minimum of eighteen years of age to purchase restricted use pesticides and to make pesticide applications. Federal 171.201 generally requires a noncertified RUP user to be at least 18, with a narrow 16-year-old exception only for certain private-applicator immediate-family uses that are not fumigants, sodium cyanide, or sodium fluoroacetate, and not aerial. Do not import that family-farm exception onto a commercial Oklahoma crew. For the applications this program describes, plan on 18.
A person who is already certified in one category but not in the category of today's job is still a noncertified applicator for that use under 171.201(c)(4). Oklahoma OAC 35:30-17-25(d) does allow a certified applicator to work as a service technician in other categories for a licensed company without taking the service technician exam. That courtesy does not make them the 171.201 supervisor for a category they do not hold, and it does not let them act as the certified applicator named on a license in a category they have not finished.
| Status | What they passed | What they may do | What they may not do |
|---|---|---|---|
| Certified applicator | Core plus category, plus practical where required | Apply and supervise in that category; be the certified applicator under a license | Supervise a use outside their certified categories |
| Temporary certified applicator | Written exams only; practical still open | May qualify as a service technician | Act as the certified applicator for a license |
| Service technician | Service technician exam; employer-held $20 ID | Apply when the technician or a certified applicator is present | Run the company as the license's certified applicator; advertise as a technician without an issued ID |
| Nonservice technician / uncertified helper | Neither certified-applicator nor service-technician credentials | Work only with a certified applicator on site | Make the application alone on a commercial route |
The Federal Floor: 40 CFR 171.201
Section 171.201 applies when a certified applicator allows or relies on a noncertified applicator to use a restricted use pesticide under that certified applicator's direct supervision. It does not rewrite Oklahoma's presence rule, and it does not shrink a label. The certified applicator must have practical knowledge of applicable Federal, State, and Tribal supervisory requirements, including anything the product labeling says about noncertified users.
Before the noncertified person uses the RUP, the certified applicator must ensure all of the following.
Competence and qualifications. The noncertified applicator must meet 171.201(c) in at least one listed way: pesticide-safety training that meets 171.201(d) within the last 12 months; agricultural handler training under 40 CFR 170.501 within the last 12 months; a certifying-authority program that meets or exceeds 171.201(c)(1); or current certification that simply does not cover this type of application or this jurisdiction. They must also have been instructed within the last 12 months in the safe operation of any equipment they will use to mix, load, transfer, or apply pesticides.
171.201(d) training content is pesticide-safety training, not a substitute for your category exam. It must be presented orally from written materials or audiovisually, in a manner the person can understand (including through a translator). The trainer must stay for the entire program and answer questions. The trainer must be a currently certified RUP applicator, a designated trainer of certified applicators or handlers, or a person who completed an EPA-approved pesticide safety train-the-trainer program for handlers under 40 CFR part 170. Topics include toxicity and exposure hazards, routes of entry, signs of poisoning, first aid and decontamination, when to get emergency medical care, hygiene and wash-water rules, hazards to children and pregnant people, how to read labeling (including the restricted-use statement and when labeling requires the certified applicator to be physically present), PPE, heat illness, spill cleanup, environmental concerns such as drift and runoff, and the supervisor's duties to give site-specific instructions and keep communication open. Independent OpenExamPrep study lists those topics so you can recognize a complete training event; it is not an official ODAFF or EPA course packet.
Use-specific instructions. Before use, the certified applicator must give instructions specific to the site and the pesticide. Those instructions must cover labeling directions, precautions, and requirements for that use and site, and how site characteristics (surface and ground water, endangered species, local population) and application conditions (equipment, method, formulation) might increase or decrease the risk of adverse effects. The certified applicator must provide this information in a manner the noncertified applicator can understand. If the technician's strongest language is not the language printed on the label, you still owe understandable instructions. Pointing at an English label and saying "just follow that" does not meet 171.201 when the person cannot use that label as working instructions.
Labeling, PPE, and equipment. The noncertified applicator must have access to the applicable product labeling at all times during use. Where labeling requires personal protective equipment, the certified applicator must ensure that clean, labeling-required PPE is in proper operating condition and is worn and used correctly. Before each day of use, equipment used for mixing, loading, transferring, or applying must be in proper operating condition as the manufacturer intended, without a reasonably foreseeable risk of adverse effects to the noncertified applicator, other people, or the environment.
Availability of the supervisor. Two separate federal duties are easy to collapse into a slogan, and the slogan is wrong. First, a means to immediately communicate with the certified applicator must be available to each noncertified person using RUPs under that supervision. Second, the certified applicator must be physically present at the site of the use when required by the product labeling. Immediate communication is not a substitute for physical presence when the label requires presence. "Radio supervision from another county is always OK" is not a 171.201 rule. Radio or phone can be the required communications link when the label does not demand presence and Oklahoma's on-site person is a lawful service technician or certified applicator. It cannot cure a missing technician, a missing category credential, missing 12-month training, or a label that says the certified applicator must be there.
Records. If the supervisor is a commercial applicator, that person must create or verify records documenting each noncertified applicator's qualifications under 171.201(c) before allowing RUP use under that supervision. For 171.201(d) training, the record includes the noncertified applicator's printed name and signature, the date the training requirement was met, the name of the person who provided the training, and the title or description of the training. Keep those records accessible at the commercial applicator's principal place of business for two years from the date the noncertified applicator used the RUP. Oklahoma's OAC 35:30-17-25(h) independently requires approved safety training consistent with 171.201 before a noncertified applicator applies an RUP, with employer records for at least two years (printed name and signature, trainer name, date completed, title or description). That Oklahoma subsection does not apply to a noncertified applicator making an RUP application on a family farm; it does apply to the commercial restaurant and structural work this chapter uses as examples.
171.201 also carves out laboratory research involving RUPs and physicians or veterinarians applying RUPs to patients in ordinary professional practice. Those exceptions are not a restaurant pest-control loophole.
Oklahoma's Presence Rule Is Stricter for These Applications
OAC 35:30-17-25 restates the field picture in operational order:
- A certified applicator shall be on site to use any pesticide when required by the label or labeling.
- A certified applicator shall be on site to supervise any pesticide application by a non-service technician.
- A service technician shall be on site to make the actual application of any pesticide unless a certified applicator is present at the job site.
- A certified applicator may work as a service technician in other categories for a licensed company without completing the service technician examination.
Put a 7A restaurant route in that grid. Category 7A (General Pest) covers pesticide application within and immediately adjacent to a structure, with "immediately adjacent" meaning not farther than three feet from the structure; applications to restaurants are permitted in this category. It does not cover fumigation, termites and other wood-destroying organisms in or on a structure, or bird and predatory-animal work. If the person on the route has no service technician identification and is not a certified applicator in 7A, Oklahoma requires the certified applicator on site. You cannot let an uncertified helper run that route alone, "because they have been shown the account book," or "because they can call you from the truck." If the person is a properly identified service technician, Oklahoma's presence rule is met by the technician being there—but the label can still demand the certified applicator in person, and any RUP still triggers 171.201 training, instructions, equipment, records, and immediate communication with a supervisor who is certified in 7A.
The supervisor remains responsible for the application. 171.201 is written against the certified applicator who allows or relies on the noncertified user. 2 O.S. § 3-86 separately makes it unlawful to operate in a negligent manner causing off-target drift, to use a pesticide inconsistent with its labeling, to advertise in a category for which no license is held, and to employ people as certified applicators or service technicians unless they have met Board standards and hold valid credentials. If the mix, the site, or the drift is wrong, "I was not in the building" is not a defense when you were the supervising certified applicator who put that person on the account.
Do not supervise outside your category. A 3A ornamental and turf certificate does not authorize you to direct a 7B termiticide application. A 7A certificate does not authorize you to supervise 7C fumigation. If you are certified in 7A and the company also holds 7B, you still need 7B certification (including the practical, not merely temporary written status) before you are the certified applicator for that license category or the 171.201 supervisor for that use.
Worked Decision Path
Before anyone leaves the shop, ask four questions in order: (1) What category is this use, and am I certified in it—not merely Core-tested, and not merely temporary after the written exam? (2) Does the labeling require me to be physically present? If yes, I go. (3) Who will actually apply—certified applicator, service technician with a current employer-issued identification, or an uncertified helper? Helpers require me on site in Oklahoma. (4) If the product is an RUP, have I delivered understandable use-specific instructions, confirmed 171.201 qualifications and equipment training within 12 months, confirmed age 18, confirmed labeling and PPE access, confirmed equipment condition, confirmed a way to reach me immediately, and verified the training record exists?
That sequence is how independent OpenExamPrep study converts 171.201 and the Oklahoma overlay into a go/no-go decision instead of a hope that the radio will cover it.
