Certification Scope and Supervision on a Multi-Site Job

A commercial applicator holds a certified applicator credential in the appropriate category and is scheduled to treat two sites: a farm field (agricultural) and a school grounds (institutional). The school job is added at the last minute, and the applicator's credential category may not cover institutional sites without an additional category. The applicator also employs an uncertified technician who will handle mixing and loading at the farm site under the applicator's supervision. The label for the product used at the school requires a posted notification and a re-entry interval, and the school has children present during the day. The applicator must decide whether to accept the school job, how supervision of the technician must work, and what notifications are required.

1. What must the applicator verify about certification category and supervision before accepting the school job and using the technician?

Read the worked answer

Verify that the credential covers the site category - institutional/right-of-way/ornamental categories differ from agricultural, and applying outside the certified category is a violation. If the school site requires a category the applicator lacks, the job must be declined or reassigned to a properly certified applicator. For the technician: an uncertified person may generally mix, load, or apply only under the direct supervision of a certified applicator as defined by the label and state rules - 'direct supervision' typically means the certified applicator is physically present or immediately available, depending on the state and label. The applicator must confirm the state's supervision standard, ensure the technician has the required PPE and training, and remain responsible for the application. The applicator cannot simply drop the technician at the farm site while working the school site if the label or state requires on-site supervision.

2. What notification and timing requirements apply at the school, and how do they interact with the REI and children's presence?

Read the worked answer

Read the label and state school-integrated pest management rules: many states require prior notification of parents/staff, posting of signs at application points and entrances, and application when children are not present (after hours, weekends, or breaks). The label's posted-notification requirement and REI must both be met - posting does not shorten the REI, and the REI does not replace posting. Because children are present during the day, the application should be scheduled outside school hours or in an area closed off until the REI expires, with signs posted per the label and state rule. Confirm who must be notified (school administrator, parents on a registry) and the required lead time. If the label or state prohibits application while children are present, the daytime schedule must change.

3. What records and documentation should the applicator keep for both sites?

Read the worked answer

For each site: applicator name and certification number and category, date and time, site address/description, product and EPA reg. number, rate, carrier volume, target pest, weather, and the certification basis for the site category. For the school: the notification method and date, posting locations and times, REI start and end, and confirmation that children were absent or the area was closed. For the technician: supervision arrangement, training and PPE verification, and who was on site. Keep records for the state-required retention period and make them available on request. If the category does not cover the school, document the decision to decline or reassign - do not create a record that implies coverage the applicator lacks.
