What Does a Site Safety and Health Officer (SSHO) Do on a Federal Jobsite?

On a federal or military construction project, the Site Safety and Health Officer (SSHO) isn’t a formality, it’s a contractually required role, and the person in it carries real authority to stop unsafe work. If you’re preparing for a USACE project, or trying to understand what this role actually involves, here’s a breakdown of the job.

What Is an SSHO?

A Site Safety and Health Officer is the individual responsible for implementing and enforcing the project’s Accident Prevention Plan (APP) and Activity Hazard Analyses (AHAs) on a federal construction site. Under EM 385-1-1, USACE projects require a qualified SSHO to be present, and their role is defined by the contract, not just company policy.

The SSHO isn’t an outside inspector who visits occasionally. On most federal contracts, they’re expected to be on site full-time during construction operations, monitoring conditions, documenting compliance, and having the authority to halt work when a hazard isn’t controlled.

Core Responsibilities of an SSHO

• Implementing and enforcing the project’s Accident Prevention Plan (APP)
• Reviewing and helping develop Activity Hazard Analyses (AHAs) for each phase of work
• Conducting daily site safety inspections and documenting findings
• Leading or coordinating daily safety briefings and pre-task planning
• Investigating incidents, near misses, and documenting corrective actions
• Verifying subcontractor compliance with site safety requirements
• Maintaining the authority to stop work when hazards aren’t adequately controlled

That last point is what separates a real SSHO from a title on an org chart. Stop-work authority has to be explicit, and it has to be something the SSHO is actually empowered to use without needing sign-off from a superior first.

SSHO Qualifications and Certification

EM 385-1-1 sets specific qualification requirements for SSHOs on USACE projects, and they typically include:

• Completion of the 40-hour EM 385-1-1 construction safety course
• OSHA 30-Hour Construction certification
• Relevant field experience in construction safety, often several years, depending on project size and complexity
• For larger or more complex projects, additional credentials like Safety Trained Supervisor Construction (STS-C) may be required or preferred

Contracting officers will review SSHO qualifications before mobilization, and a candidate who meets the training requirement on paper but lacks practical field experience is a common reason projects get flagged during pre-construction review.

Why the SSHO Role Matters Beyond Compliance

It’s easy to think of the SSHO as a documentation role, someone who fills out forms and keeps a project audit-ready. But on an active jobsite, the SSHO is often the person deciding, in real time, whether a crew proceeds with a lift, an excavation, or a confined space entry.

That decision requires field credibility. An SSHO who has actually worked hoisting and rigging operations, or spent time on federal construction sites, carries a different kind of authority than one who only knows the regulations from a classroom.

What to Look for When Hiring or Contracting an SSHO

1. Confirm current EM 385-1-1 (40-hour) and OSHA 30 certifications, not expired or in-progress training.
2. Ask about direct field experience on federal or military construction projects, not just general industry safety work.
3. Verify they understand the specific scope of your project, hoisting and rigging, excavation, confined space, and hold relevant qualifications for those hazards.
4. Make sure stop-work authority is documented and unambiguous, not something that requires escalation before it can be used.
5. Look for someone who treats safety as an active, daily practice, not a paperwork exercise completed after the fact.

The Bottom Line

The SSHO role exists to close the gap between a safety plan on paper and what actually happens on the jobsite. On federal projects, that role carries contractual weight, and the qualifications behind it matter as much as the title.
