How long does OHS training take? Minimum hours for initial and periodic training
“How long will it take?” - that is one of the first questions an OHS officer hears when a company plans training for its team. The answer does not come down to a single number: the Polish regulation on training in the field of occupational health and safety sets separate minimum durations for general instruction, job-specific instruction and periodic training for each job group. And since fines for training gaps rose to PLN 60,000 (from 8 July 2026), vague assurances that “OHS training is an hour, maybe two” have become a mistake that can prove costly.
How long does initial OHS training take?
Every newly hired employee, every student on an internship and every pupil in practical vocational training must complete initial training - always before being allowed to work (§ 10-11 of the regulation). It consists of two parts, and for each of them the framework curriculum (Annex 1) sets a minimum number of lesson hours:
| Part of initial training | Minimum duration |
|---|---|
| General instruction | 3 lesson hours |
| Job-specific instruction - manual work stations and other stations exposed to harmful, nuisance or hazardous factors | 8 lesson hours |
| Job-specific instruction - administrative and office workers exposed to nuisance factors | 2 lesson hours |
The conversion is fixed, because one lesson hour lasts 45 minutes. General instruction therefore takes at least 2 hours 15 minutes of clock time, and complete initial training at a manual work station means a minimum of 11 lesson hours - about 8 hours 15 minutes of clock time. These are minima: the detailed programme drawn up by the employer or the training organiser may provide for more, and the duration of job-specific instruction should additionally be adjusted to the employee’s vocational preparation, length of service and the hazards present at the work station (§ 11 ust. 4). The same values are confirmed by the Polish labour inspectorate (PIP) in its legal advice on OHS training.
How long does periodic OHS training take?
For periodic training, the minimum duration depends on the job group - the five framework programmes (parts IV-VIII of Annex 1) provide five different minima:
| Job group | Permitted forms | Minimum duration |
|---|---|---|
| Employers and other persons supervising employees | course or seminar | 16 lesson hours |
| Manual workers | instruction | 8 lesson hours |
| Engineering and technical staff | course, seminar or guided self-study | 16 lesson hours |
| In-house OHS service, instructors and lecturers | course, seminar or guided self-study | 32 lesson hours |
| Administrative and office workers | seminar, course or guided self-study | 8 lesson hours |
Converted to clock time, a single periodic training session for employers, supervisors and engineering and technical staff therefore lasts 12 clock hours, for manual workers 6 clock hours, and for the in-house OHS service as many as 24 clock hours. The form is not a free choice: for manual workers the regulations provide on-the-job instruction only, while for the remaining groups a course, a seminar or guided self-study is allowed - the colloquial “e-learning”, which we discuss in our article on online OHS training. The employer sets the frequency and duration of periodic training after consulting employees (§ 15 ust. 3), but cannot go below the framework minima.
How often must OHS training be repeated?
The duration of a single training session is half of the answer - the other half is the cycle. The regulation ties the frequency to the job group (§ 15): manual workers repeat periodic training no less often than every 3 years, and every year at work stations involving particularly hazardous work; employers, supervising persons, engineering and technical staff, the in-house OHS service and persons exposed to harmful factors - every 5 years; office workers - every 6 years. The first periodic training must be organised sooner: for employers and supervising persons within 6 months of starting work, for the remaining groups within 12 months. The full schedule of deadlines, including exemptions from periodic training, is described in our article Periodic OHS training: how often? Deadlines for every job group, and our OHS training offer covers current dates for specific groups.
When can training be shortened or skipped?
The regulation provides narrow circumstances in which periodic training is unnecessary, although no provision shortens the minimum hour counts. A person may be exempt from periodic training if they present a valid certificate of completing the required training with another employer within the same period, or completed periodic training for another job group in that period, provided the programme covers the scope required at the new work station (§ 15 ust. 5). In turn, § 17 recognises as equivalent to periodic training the completion, within the given period, of vocational further training or skills improvement, if it covers the periodic training programme appropriate for the work station. In both cases the burden lies with the employer - who must present the certificate or the programme of the completed training.
How to document training durations - a checklist for employers
During a labour inspection, PIP verifies not only whether the training took place, but also whether it had the correct form and duration. Three things are worth keeping in check:
- Check that the training programme for each job group, drawn up on the basis of the framework curriculum in Annex 1, specifies the subject matter, the form of delivery and the duration (§ 7).
- Confirm completed training in writing: initial training on the initial training card kept in the personnel files (§ 12), periodic training with a certificate issued after a positive exam before the commission, with a copy in the personnel files (§ 16).
- For an inspection, prepare the programmes, class registers and certificates - PIP’s legal advice confirms that the training form, the exam and the documentation are all subject to verification.
Well-kept documentation settles most disputes: when the question arises whether “the training lasted as long as required”, the answer is the card or the certificate with the hours itemised, not the participants’ memory.
Key takeaways
- Initial OHS training is a minimum of 3 lesson hours of general instruction plus 8 lesson hours of job-specific instruction (manual and other exposed work stations) or 2 lesson hours (office work stations exposed to nuisance factors).
- Periodic OHS training takes a minimum of 8 lesson hours for manual and office workers, 16 for employers, supervising persons and engineering and technical staff, and 32 for the in-house OHS service; one lesson hour is always 45 minutes.
- The minimum hour counts cannot be shortened by going online or by industry - only the number of training sessions can be reduced, and solely under the conditions of § 15 ust. 5 and § 17.
Need to organise OHS training for your company?
If you do not have time to track the minima and deadlines, an external OHS service will take over the task: it will calculate the dates, select the formats and handle the documentation. Check our OHS training offer or contact us - we will advise how long training in your company will take and when it needs to be repeated.
FAQ - frequently asked questions about OHS training duration
How long does initial OHS training take? A minimum of 3 lesson hours (2 hours 15 minutes of clock time) of general instruction plus job-specific instruction: 8 lesson hours (6 clock hours) at manual work stations and stations exposed to harmful factors, or 2 lesson hours for office workers exposed to nuisance factors. In total at least 11 lesson hours - about 8 clock hours - at a manual work station (§ 8 and Annex 1 of the regulation).
How long does periodic OHS training take? It depends on the job group: 8 lesson hours for manual workers and administrative and office workers, 16 lesson hours for employers, persons supervising employees and engineering and technical staff, 32 lesson hours for the in-house OHS service (parts IV-VIII of Annex 1). In clock time that is 6, 12 and 24 hours respectively.
How long does online OHS training take? The online form (guided self-study) does not reduce the minimum number of hours - the same minimum applies as in the classroom form. Moreover, guided self-study is legal only for the periodic training of selected job groups and requires consultations with persons meeting the requirements for lecturers, as well as an exam before the commission (§ 1a pkt 5, § 15 ust. 2, § 16).
Is a lesson hour the same as a clock hour? No. In the framework training curricula all durations are given in lesson hours lasting 45 minutes (Annex 1 to the regulation). To convert to clock time, multiply the number of lesson hours by 0.75 - e.g. 16 lesson hours is 12 clock hours.
How often must OHS training be repeated? Manual workers: no less often than every 3 years, and every year for particularly hazardous work. Employers, supervising persons, engineering and technical staff, the in-house OHS service and persons exposed to harmful factors: every 5 years. Office workers: every 6 years (§ 15). The first periodic training: within 6 months (employers and supervising persons) or 12 months (remaining groups) of starting work.
How long is OHS training for interns and students? Students on internships and pupils in practical vocational training complete general instruction before being allowed to work (§ 10 ust. 1), and job-specific instruction - when the internship concerns a manual work station or a station exposed to harmful factors (§ 11 ust. 1 pkt 3). The same minimum hour counts apply as for employees; the regulations provide no separate, shortened programmes for interns.
