What changed for SSHOs in the 15 March 2024 edition of EM 385-1-1
The manual most SSHO summaries still quote was superseded in March 2024. Eleven things about the role changed. Here they are, side by side, with paragraph references.
SSHO guides
Plain-English guides to the Site Safety and Health Officer requirement on federal construction contracts, written against the current 15 March 2024 edition of USACE EM 385-1-1 rather than the 2014 edition most summaries still quote. Every guide says which paragraph it comes from, so you can check it.
Guides
Is there an SSHO certification?
Nobody can sell you an SSHO certification, because no such thing exists. What does exist is a credential that takes two years off the experience bar.
SSHO vs competent person
They get used interchangeably on site and they are not interchangeable. The difference decides who can sign an AHA and who can run a crew.
ENG Form 6282, the SSHO designation letter
A mandatory form, two signatures, and a hard gate: work must not be conducted until the government accepts it. It did not exist in the 2014 manual.
How to become an SSHO
There is no course that makes you one. There is a sequence, it takes three to five years, and the order you do it in changes how long it takes.
Does NAVFAC require an SSHO?
Usually yes, but not for the reason people give. The requirement does not come from EM 385-1-1 on a Navy job — it comes from the specification.
SSHO continuing education: what counts toward the 24 hours
The requirement changed in 2024 and the volume did not, which is why almost everyone still has the cadence wrong. Four rules decide what counts.
Does my contract actually require an SSHO?
There is no dollar threshold that switches the requirement on. It is in your own paperwork, and it takes about ten minutes to find.
Can my superintendent be the SSHO?
It is the first thing every contractor asks, because it would save a salary. The answer rests on one sentence, and that sentence changed in 2024.
Who covers when your SSHO leaves site?
The Designated Representative no longer exists. If someone offers you one, they are quoting a manual that was superseded in March 2024.

What is an SSHO?
The role itself: the three levels, who it reports to, what the job covers day to day, and why it is not a second hat for your superintendent.
SSHO requirements
The qualification bar item by item — training, documented experience, keeping current, and the designation letter the government has to accept.
Which of these are you?
I need an SSHO
You have a contract that requires one and you are short a person, or you are not sure the person you have qualifies.
I want to work as an SSHO
You already meet the bar, or you are close, and you want to be on somebody's designation letter.
I want to become one
You are starting from further back and want to know the route, the timescale and the shortcut.
