Under the 15 March 2024 edition of EM 385-1-1, an SSHO must have taken 24 hours of documented formal classroom or online safety and health training within the past five years, and must keep taking 24 hours in every three-year period for the duration of the contract.
The 2014 manual said eight hours every year. Twenty-four over three years is the same volume, which is exactly why this change slips past people — the arithmetic looks identical, so nobody re-reads it. But the cadence, the look-back and the record-keeping are all different, and the hours an SSHO can actually count are not the hours most training files are built from.
If you were told "eight hours a year", that was the 2014 manual. It is still the number on most consultants' one-pagers, in a lot of job descriptions, and in most of what a search on this returns. The current requirement is 24 hours per three-year period with a five-year look-back, and a training file built as twelve tidy annual eight-hour records is not automatically a compliant one — it depends what is in those hours. The rest of the 2024 changes are here.
The four rules that decide what counts
1. The OSHA 30-hour course does not count
This is the single most common error in an SSHO's file. The initial OSHA 30-hour course is a separate requirement in its own right, and it does not count toward the 24 hours. A file showing a 30-hour card and nothing else shows zero hours of continuing education, not thirty.
2. It has to be formal, and documented
Formal classroom or online safety and health training. Toolbox talks, tailgate meetings and on-the-job coaching are part of the SSHO's own duties — they are not continuing education hours. And "documented" is load-bearing: a course you took without a certificate, a transcript or a dated record is a course you cannot count when somebody asks.
3. Teaching counts — but each course only once
Hours spent instructing safety training count toward the requirement. This is a real benefit for working SSHOs, who often teach. The limit is that each course counts once. Running the same four-hour fall protection class three times in a year is four hours, not twelve. Teaching a different four-hour class is four more.
4. Two clocks, not one
There is a five-year look-back — 24 hours within the past five years — and a rolling three-year obligation for the duration of the contract. They are different tests and you have to satisfy both. Someone who did 24 hours four years ago and nothing since passes the look-back and fails the current three-year period.
Where this actually bites. Not at audit — at designation. The contracting officer or COR is accepting an ENG Form 6282 for a named individual, and the training record is part of what makes that individual qualified. A thin file holds up a start, and starts are expensive. See ENG Form 6282.
How to keep the record so it survives a question
- One row per course, with the date, the title, the provider, the delivery method and the hours. Not a folder of PDFs — a list, with the PDFs behind it.
- Mark the OSHA 30 as excluded on the record itself, so nobody helpfully adds it back into the total.
- Mark teaching hours as teaching, with the course identified, so the count-once rule can be checked rather than assumed.
- Keep two running totals — the trailing five years and the current three-year period — and look at them quarterly rather than when a designation is due.
- Keep it per person, not per company. The requirement attaches to the individual SSHO and travels with them between contracts.
A note on the contracting officer's discretion
The contracting officer, in coordination with the local safety and occupational health office with jurisdiction over the work, may adjust the training and experience requirements, and may accept training covering the same subjects and this manual in place of the OSHA 30. That cuts both ways and it lives in your contract rather than in the manual — so read the contract before concluding that the manual's default is your number.

We are building these hours
We are putting together continuing education aimed at this role specifically — built around what federal construction contracts actually require, on the current edition of the manual, and documented in the form a designation letter needs. It comes in eight-hour modules, because the manual allows the 24 hours to be multiple classes combined, so three of them carry you through a three-year period. What it covers and what it will cost — and to be plain about where it is, enrolment is not open and nothing on this site takes a card. Tell us where to send it when it is ready.
