TLDR: A Site Safety and Health Officer (SSHO) is the contractor-designated safety professional required on most USACE, NAVFAC, and federal construction projects under EM 385-1-1. SSHO requirements vary by level and include OSHA 30 or an accepted equivalent, documented competency training, similar-project experience, ENG Form 6282 acceptance, and daily site presence. An OSHA 30 card alone does not make someone a qualified SSHO, and the role is contract-driven, not a universal OSHA job title, so contractors must verify every requirement against the specific contract and the applicable EM 385-1-1 edition before mobilization.
Contractors often discover site safety and health officer requirements at the worst possible moment: during bid review, right before mobilization, or when a contracting officer rejects their safety submittal package. The consequences of that discovery range from delayed project starts to lost contract opportunities.
The core problem is that most available information about SSHO qualifications is either too generic (confusing SSHOs with general safety officers) or too thin (listing OSHA 30 and calling it done). The right question is not “Who has an OSHA 30 card?” but “Who can be documented, designated, accepted, and effective for this specific contract, scope, risk level, and crew?”
This guide covers what an SSHO is, when one is required, the Level 1 through Level 3 framework under the current EM 385-1-1, training and experience requirements, daily duties, required documentation, and common mistakes that delay projects.
Looking for qualified safety professionals for a federal construction project?
Quick Takeaway: SSHO Requirements at a Glance
A Site Safety and Health Officer (SSHO) is a contract-mandated safety professional required on USACE, NAVFAC, and federal construction projects under EM 385-1-1. Primary qualifications include:
Training: OSHA 30-Hour card (or accepted equivalent) plus 24 hours of documented SOH competency training within the last 5 years.
Experience: 3 to 5 years of cumulative, similar-project safety management (reducible with an accredited CSP/CHST credential or safety degree).
Mandatory Submittals: Accepted ENG Form 6282 (Designation Letter) signed by corporate safety leadership and the contracting officer before mobilization.
Key Restriction: A Level 1 SSHO must be full-time on-site and cannot double as a production superintendent or supervise non-safety personnel.
What Is a Site Safety and Health Officer?
A Site Safety and Health Officer (SSHO) is the contractor employee responsible for overseeing and ensuring implementation of the prime contractor’s safety and occupational health (SOH) program at the site of work. The role is defined by EM 385-1-1, the U.S. Army Corps of Engineers Safety and Occupational Health Requirements Manual, and tied to required qualifications, site presence, documentation, inspections, safety orientation, and accident reporting duties.
In plain terms, the SSHO is the person the contractor designates, documents, and gets accepted to manage the jobsite safety system. This is not a “safety watcher” role. The SSHO keeps the Accident Prevention Plan (APP) current, helps manage Activity Hazard Analyses (AHAs), inspects the site daily, tracks deficiencies, trains and orients site personnel, and supports incident and near-miss reporting.
The acronym SSHO stands for Site Safety and Health Officer. You will see it on federal construction contracts, USACE project specifications, NAVFAC contract requirements, and sometimes in private-sector or municipal specifications that borrow federal safety language.
When Is an SSHO Required?
The SSHO requirement is contract-driven. Not every construction site uses the title. The role most commonly appears on USACE, NAVFAC, Department of Defense, and other federal construction projects where EM 385-1-1 compliance is written into the contract.
Some private owners, municipalities, utilities, and insurance-driven specifications also require a designated site safety and health officer, especially when the project involves high-risk work or the owner adopts federal-style safety language.
OSHA requires employers to comply with applicable standards, maintain safety programs, provide required training, and implement hazard controls. But OSHA does not make “SSHO” a universal job title for every construction project. Confusing OSHA’s general employer obligations with the contract-specific SSHO requirement is one of the most common mistakes contractors make. Understanding the general duty clause helps clarify where OSHA’s baseline ends and contract-specific requirements begin.
Start with the contract, not the job title. Pull the safety section. Check whether it references EM 385-1-1 and which edition applies. The current edition is effective March 15, 2024, but existing contracts may continue under the prior edition until completion.
Key Differences: Federal EM 385-1-1 vs. Standard OSHA 1926
Understanding the distinction between contract-driven EM 385-1-1 standards and baseline OSHA Construction (29 CFR 1926) requirements prevents costly submittal rejections.
Requirement | Standard OSHA Construction (29 CFR 1926) | Federal EM 385-1-1 (USACE / NAVFAC) |
Site Safety Role | Requires a “Competent Person” for specific hazardous tasks (e.g., scaffolding, trenching). | Requires a formally designated SSHO overseeing the entire Safety & Occupational Health (SOH) program. |
Full-Time Presence | Required only during high-risk activities as dictated by specific standards. | Mandatory full-time presence for Level 1 SSHO whenever work is actively performed on-site. |
Documentation | Written plans required for specific standards (e.g., HazCom, Respirators). | Requires full Accident Prevention Plan (APP), Activity Hazard Analyses (AHAs), and ENG Form 6282. |
Dual Roles | Production supervisors can serve as the designated competent person. | Level 1 SSHOs are strictly prohibited from supervising production crews or non-safety personnel. |
Continuing Education | No universal annual hours mandate outside standard-specific refresher training. | 24 hours of documented SOH competency training required every 3 years. |
You likely need to verify SSHO coverage if:
Your contract references EM 385-1-1.
Your project is USACE, NAVFAC, DoD, or other federal work.
The contract requires an APP/AHA package before work begins.
The owner requires a dedicated site safety professional.
Your project has high-risk work, multiple shifts, or multiple work locations.
The contract requires ENG Form 6282 or a designated SSHO.
SSHO Requirements at a Glance
The 2024 EM 385-1-1 defines three SSHO levels plus an alternate SSHO. This table summarizes the key requirements for each.
Requirement | Level 1 SSHO | Level 2 SSHO | Level 3 SSHO |
|---|---|---|---|
Safety responsibility | Full-time | Collateral duty | QP/CP with SOH responsibility |
Initial training | OSHA 30 (construction or general industry) or accepted equivalent | OSHA 30 or accepted equivalent | Determined by QP/CP role and work performed |
Ongoing competency training | 24 hours documented SOH training within last 5 years, then 24 hours every 3-year period during contract | Same structure | Based on required QP/CP scope |
Experience | 5 years cumulative in last 10 on similar projects (reducible to 3 with qualifying degree/certification) | 3 years cumulative in last 10 on similar projects (reducible to 2 with qualifying degree/certification) | Experience sufficient to identify hazards and implement controls |
High/extremely high residual RAC projects | Required | Not allowed | Not allowed |
Can supervise non-safety personnel? | No | Collateral role by definition | Per scope |
A critical point many contractors miss: Level 2 and Level 3 SSHOs cannot be assigned to projects with a residual Risk Assessment Code (RAC) of high or extremely high. Only a Level 1 SSHO satisfies that requirement.
Level 1 SSHO Requirements in Detail
A Level 1 SSHO carries full-time safety and occupational health responsibility. This is the default requirement for most federal construction projects, and it is mandatory for projects with high or extremely high residual RAC.
Training requirements:
OSHA 30-hour construction or general industry course completion, or an accepted equivalent.
24 hours of documented formal classroom or online SOH-related training within the past five years.
Continued 24-hour competency training every three-year period during the contract.
A point that trips up many contractors: the initial OSHA 30 does not count toward the 24-hour competency training requirement. These are separate obligations. Someone with an OSHA 30 card but no additional documented SOH training in the last five years may fail the submittal review. For a broader look at what OSHA requires for training, see this overview of OSHA required training.
Experience requirements:
Five years of cumulative safety experience within the last 10 years managing or implementing a SOH program on projects similar in industry type, size, and complexity to the contract scope.
A safety-related degree or qualifying nationally accredited safety certification can reduce the experience requirement to three years.
The word “similar” matters enormously. A safety professional with five years in oil and gas does not automatically qualify for a federal vertical construction project. A residential safety coordinator does not automatically qualify for heavy civil, dredging, or environmental cleanup work. Practitioners on Reddit confirm this gap is real. One job-seeker with over four years of oil-and-gas safety experience and EM 385-1-1 training reported difficulty landing SSHO positions on federal projects because the experience did not align with the project type.
Site presence:
A Level 1 SSHO must be at the site of work whenever work is performed.
Level 1 SSHOs are not permitted to supervise non-safety personnel at the site of work.
That second point is a dealbreaker for contractors who want their superintendent to double as the SSHO. If the contract requires a Level 1 SSHO, the person cannot also run production crews.
Level 2 and Level 3 SSHO Requirements
Level 2 SSHO is a collateral-duty role. The person handles safety and occupational health responsibilities alongside other project duties, but still needs OSHA 30 or an accepted equivalent, 24-hour competency training, and three years of cumulative similar-project experience within the last 10 years. A qualifying degree or certification can reduce the experience threshold to two years.
Level 3 SSHO is a designated qualified person (QP) or competent person (CP) with SOH responsibility. The requirements center on having experience sufficient to identify hazards and implement controls for the specific work being performed. This level is less prescriptive on paper, but the contracting officer still has to accept the designation.
Both Level 2 and Level 3 SSHOs are prohibited on projects with high or extremely high residual RAC. When the risk profile pushes into those categories, only a Level 1 SSHO will satisfy the site safety and health officer requirements.
The contract or the contracting officer (KO), in coordination with the local Safety and Occupational Health Office (SOHO), determines which SSHO level applies. Contractors should not assume a lower level is acceptable without written confirmation.

Is OSHA 30 Enough to Be an SSHO?
No. This is the single most common misconception about SSHO requirements.
OSHA 30 is commonly required as part of the SSHO qualification package, but an OSHA 30 card by itself does not make someone an SSHO. OSHA’s own Outreach Training Program page states clearly that the program is voluntary, does not meet OSHA standard-specific employer training requirements, and none of the Outreach courses is considered a certification.
Despite this, contractors and even some training providers casually use phrases like “OSHA certified” or “OSHA 30 certified.” Those phrases are inaccurate. OSHA issues course completion cards through the Outreach program, not certifications.
Under EM 385-1-1, the SSHO still has to meet the applicable level, documented competency training, similar-project experience, designation requirements, and contract acceptance. OSHA 30 is one piece of a much larger qualification package.
A related concern from the field: practitioners on Reddit have noted that some EM 385-1-1 training courses have not updated to the 2024 edition. Before relying on any training certificate, verify the date, course content, and whether the project’s KO or COR will accept it.
For more on what OSHA 30 training covers and how it fits into broader construction safety training requirements, that guide breaks down the details.
What About CHST, CSP, or Other Certifications?
Certifications like the Construction Health and Safety Technician (CHST) or Certified Safety Professional (CSP) from the Board of Certified Safety Professionals (BCSP) can strengthen a candidate’s profile. Under EM 385-1-1, a qualifying nationally accredited safety certification may reduce the experience requirement for Level 1 or Level 2 SSHOs.
But certifications do not automatically override contract acceptance. The contracting officer must still accept the designated SSHO for the project. A CHST with no similar-project experience is not guaranteed acceptance just because the credential exists.
Safety professionals on Reddit frequently acknowledge that credentials open doors, but employers still judge practical field competence, program-building ability, communication skills, and project fit. The people reviewing your SSHO submittal are looking at the whole package.
What Does an SSHO Do on Site?
The SSHO’s job is not to “own safety alone.” EM 385-1-1 makes clear that the prime contractor, in coordination with the SSHO, is ultimately responsible for SOH program management, communication, and implementation at the site. The SSHO is the field person who keeps the accepted safety system active, documented, and corrected as conditions change.
Core duties under EM 385-1-1 include:
Being present at the site of work with full mobility and access to major operations during the shift.
Reporting to the corporate safety official, senior project manager, or corporate official.
Maintaining safety reference materials onsite, including EM 385-1-1, safety data sheets (SDSs), the APP, and manufacturer instructions.
Conducting daily inspections of work sites, materials, and equipment.
Establishing and maintaining a deficiency tracking system.
Reporting and investigating accidents and near misses.
Attending pre-construction conferences, tailgate meetings, pre-work meetings, preparatory meetings, and in-progress meetings.
Evaluating and updating the APP throughout the project.
Ensuring compliance by project personnel, subcontractors, and visitors.
Providing and keeping records of site safety orientation and indoctrination.
The inspection log should include the inspector’s name, date, areas and operations inspected, hazards identified, recommended corrective actions, person responsible for correction, and estimated and actual correction dates. This is not a checkbox exercise. It is the documentation trail that protects the contractor during audits, inspections, and incident investigations.
Common daily inspection focus areas track closely with OSHA’s FY 2025 Top 10 most-cited standards: fall protection, hazard communication, ladders, scaffolding, fall-protection training, and eye and face protection, among others.
SSHO Documentation Before Work Starts
Work cannot begin until key documents are submitted and accepted. This is where contractors lose time when they treat documentation as an afterthought.
ENG Form 6282: SSHO Designation Letter
All levels of onsite SSHOs require a designation letter. Contractors must designate SSHOs in writing on mandatory ENG Form 6282. Both the corporate safety official and the SSHO must sign it. It must be submitted to the KO or COR for acceptance. No work can be conducted until it is accepted, and a copy must be maintained at the site of work.
USACE’s Safety and Occupational Health Office lists ENG Form 6282 among contractor reference forms along with ENG Form 6206 (AHA) and ENG Form 6293 (APP Worksheet).
Accident Prevention Plan (APP)
The APP is a written, site-specific SOH plan documenting project hazards plus the policies, controls, and work practices used to minimize them. It must be developed by a competent person, reviewed and approved by the prime contractor and corporate safety official, and submitted to the KO or COR for acceptance before any contract work begins. The SSHO must conduct ongoing evaluations and updates of the APP throughout the project.
Practitioners on Reddit noted that the 2024 EM 385-1-1 changed the APP to a fillable PDF-style form instead of the narrative format many contractors were used to. Official forms should be pulled from USACE’s current forms list, not copied from old project folders. For a related look at whether your existing safety documentation meets standards, this guide on OSHA-compliant safety manuals covers foundational requirements.
Activity Hazard Analyses (AHAs)
AHAs must be prepared and documented before beginning each activity, task, or definable feature of work (DFOW). Each AHA must identify steps, hazards, controls, RAC, training requirements, equipment, inspection requirements, and named competent person or qualified person personnel where required.
Minimum Document Packet Checklist
Before mobilization, the contractor should have:
Contract safety section and any district-specific clauses
Confirmation of which EM 385-1-1 edition applies
Completed ENG Form 6282
OSHA 30 card or accepted equivalent documentation
24-hour SOH competency training records
Resume showing similar project experience (industry, size, complexity)
Degree or certification records if using experience reductions
First aid/CPR certification if required by contract
Task-specific CP/QP documentation
Accepted APP
Prepared AHAs for initial work phases
Daily inspection and deficiency tracking format
Emergency plan with evacuation, accountability, and emergency contacts
Bilingual communication plan when applicable
SSHO vs. Safety Officer, Competent Person, and Qualified Person
These roles overlap in conversation but differ in definition and authority. Mixing them up leads to rejected submittals and contract disputes.
Term | Meaning | Common Confusion |
|---|---|---|
SSHO | Contract-designated person responsible for implementing the prime contractor’s SOH program at the site under EM 385-1-1 | Not automatically anyone with OSHA 30 |
Safety officer / safety manager | Generic company job title with no universal standard definition | May or may not meet SSHO requirements |
Competent person | OSHA-defined person capable of identifying existing and predictable hazards and authorized to take prompt corrective measures | A CP may support or serve as Level 3 SSHO only if contract conditions allow |
Qualified person | Person with recognized degree, certificate, professional standing, or extensive knowledge and experience in a subject area | A QP role is task-specific, not automatically project SSHO |
Superintendent | Production and site supervision role | A Level 1 SSHO cannot supervise non-safety personnel |
OSHA 30 cardholder | Completed the Outreach program | OSHA says Outreach is not a certification and does not replace standard-specific training |
For contractors trying to figure out how site safety manager roles compare to SSHO designations, that distinction often comes down to the contract language and the applicable regulatory framework.
Special Cases: Environmental Cleanup, HAZWOPER, and High-Risk Work
Not every SSHO profile fits every project. EM 385-1-1 adds specific requirements for certain scopes.
For environmental cleanup and investigation activities, the SSHO must meet the initial, refresher, and supervisor training requirements in Chapter 36 of the manual in addition to the standard Chapter 2 SSHO training and experience requirements. The SSHO must also have at least one year of experience implementing SOH requirements on hazardous waste investigation and cleanup projects and training or experience to conduct exposure monitoring, sampling, and selecting or adjusting controls.
Other high-risk scopes that may trigger additional CP, QP, or plan requirements include demolition, crane and rigging operations, confined space entry, deep excavations, radiation work, and diving operations. The contract and the applicable EM chapters govern what additional qualifications the SSHO (or supporting personnel) must have.
Common SSHO Requirement Mistakes
Mistake 1: Assuming OSHA 30 is enough.
It is required but not sufficient. The competency training, experience, designation, and acceptance requirements exist independently of the OSHA 30 card.
Mistake 2: Using a superintendent as the Level 1 SSHO.
EM 385-1-1 prohibits Level 1 SSHOs from supervising non-safety personnel. A superintendent running crews and managing safety simultaneously violates this provision.
Mistake 3: Not having alternate SSHO coverage.
If the primary Level 1 SSHO leaves for more than 24 hours due to an unforeseen situation, an additional or alternate Level 1 SSHO must be on site. Multiple sites, multiple shifts, or large projects may require additional SSHOs identified in the contract. Contractors without a backup plan may lose production days.
Mistake 4: Not reading the full contract.
An SSHO working with USACE emphasized on Reddit that districts frequently add safety requirements above and beyond EM 385-1-1 through additional contract clauses. The manual sets the baseline. The contract may raise it.
Mistake 5: Submitting stale APP and AHA documents.
Copying documents from a previous project without updating them for current site conditions, operations, and personnel is a fast way to get a submittal rejected. The APP must stay current and site-specific, and AHAs must be updated when conditions or operations change.
Mistake 6: Treating language access as optional.
EM 385-1-1 requires SOH program information, documents, signs, and tags to be communicated in a language employees understand. Non-English-speaking worksites must have onsite interpreters or translators fluent in all spoken languages. This is not a nice-to-have. It is a compliance requirement. Contractors working with multilingual crews should explore bilingual safety training approaches that satisfy both EM and OSHA expectations.
Mistake 7: Relying on outdated training.
Training certificates that reference old EM 385-1-1 content may not be accepted. Verify that any EM 385-1-1 course reflects the current 2024 edition before submitting it as part of your SSHO qualification package.
Why SSHO Requirements Exist: The Risk Context
The strict oversight mandated by EM 385-1-1 exists for clear reasons: protecting lives and preventing project failure. Bureau of Labor Statistics (BLS) census data confirms over 5,000 fatal workplace injuries annually in the United States, with construction and extraction occupations accounting for more than 20% of total fatalities—led primarily by falls, slips, and trips.
From a compliance and financial perspective, contracting officers maintain zero tolerance for safety errors. OSHA’s annual inflation-adjusted maximum civil penalties stand at:
$16,553 per serious or other-than-serious violation.
$16,553 per day beyond the abatement date for failure to abate.
$165,534 per willful or repeated violation.
On federal jobsites, non-compliance carries even higher stakes than standard OSHA fines: immediate Work Stop Orders, default terminations, negative CPARS (Contractor Performance Assessment Reporting System) ratings, and potential debarment from future bidding. The SSHO acts as the contractor’s primary barrier against both physical incidents and catastrophic financial penalties.
How Contractors Can Prepare Before Mobilization
Use this sequence to verify SSHO readiness before submitting your safety package:
Pull the contract safety section and identify all USACE, NAVFAC, or district-specific clauses.
Confirm which EM 385-1-1 edition the contract requires.
Confirm the required SSHO level.
Identify the project’s residual RAC and whether Level 2 or Level 3 SSHOs are prohibited.
Verify whether full-time Level 1 presence is required.
Check OSHA 30 or accepted equivalent documentation.
Verify 24-hour documented SOH competency training within required timeframes.
Verify similar-project experience by industry type, size, and complexity.
Confirm whether degree or certification reductions apply and will be accepted.
Gather scope-specific credentials (first aid/CPR, HAZWOPER, fall protection CP, excavation CP, crane/rigging, confined space) as required.
Prepare and submit ENG Form 6282.
Submit for KO/COR acceptance.
Maintain the accepted form and all documentation onsite.
Plan alternate SSHO coverage for absences, shift changes, multiple sites, or remote work areas.
If the contractor cannot document these items before mobilization, the issue is not just hiring. It is project readiness.
Warning: Red Flags That Lead to Rejected Submittals
Submitting an SSHO candidate without thoroughly verifying their paperwork is one of the fastest ways to delay mobilization. Contracting Officers routinely reject candidates for these common oversights:
The “OSHA 30 Only” Trap: The candidate holds an OSHA 30 card but lacks 24 hours of documented SOH competency training within the last 5 years.
Mismatch in Project History: The candidate has 10 years of safety experience in oil & gas or residential work, but zero experience in federal heavy civil or vertical construction.
The Dual-Role Violation: Proposing a superintendent or production manager to serve as the Level 1 SSHO.
Outdated Training Material: Submitting EM 385-1-1 course completion certificates that reference older manual editions instead of the current 2024 edition requirements.
No Contingency Plan: Failing to designate an accepted Alternate SSHO to cover shift changes, illness, or multi-site operations.
When to Staff a Dedicated SSHO
Several scenarios push contractors toward needing a dedicated, qualified SSHO quickly:
A federal construction project requires a full-time Level 1 SSHO.
The prime contractor needs an accepted SSHO before Notice to Proceed or mobilization.
The existing SSHO resigns, is terminated, or takes emergency leave, and a replacement must be accepted quickly.
Multiple shifts or remote sites require alternate or additional SSHO coverage.
The project has high or extremely high residual RAC, making Level 1 mandatory.
Work includes environmental cleanup, hazardous substances, heavy civil, cranes, demolition, confined space, excavation, or utility operations.
The contractor needs bilingual field safety communication for multilingual crews.
In any of these situations, the contractor’s challenge is not just finding a person with a safety background. It is finding someone whose training, experience, and documentation will be accepted for this specific project.

Frequently Asked Questions
What does SSHO stand for?
SSHO stands for Site Safety and Health Officer. It is the contractor-designated role responsible for implementing the project’s safety and occupational health program at the site of work under EM 385-1-1.
Is an SSHO required on every construction project?
No. The SSHO role is most often required by contract, especially on USACE, NAVFAC, and federal construction projects. OSHA requires employers to maintain applicable safety programs, training, and hazard controls, but the SSHO title itself is not a universal OSHA requirement.
Is OSHA 30 enough to qualify as an SSHO?
No. OSHA 30 is commonly required as part of the SSHO qualification package, but the person must also meet the applicable EM 385-1-1 level, experience, competency training, designation, and contract acceptance requirements. OSHA states that Outreach courses are not certifications.
What is a Level 1 SSHO?
A Level 1 SSHO has full-time SOH responsibility and must meet the most stringent requirements: OSHA 30 or accepted equivalent, 24 hours of documented competency training, and generally five years of cumulative safety experience on similar projects within the last 10 years. This is the only level permitted on high or extremely high residual RAC projects.
Can a superintendent be the SSHO?
It depends on the contract and qualifications, but a Level 1 SSHO cannot supervise non-safety personnel at the site of work under EM 385-1-1. That restriction typically prevents a production superintendent from serving as the full-time Level 1 SSHO.
What is ENG Form 6282?
ENG Form 6282 is the mandatory SSHO Designation Letter required by EM 385-1-1. The corporate safety official and the SSHO must both sign it, it must be submitted to the KO or COR for acceptance before any work begins, and a copy must be kept at the site.
What is the difference between an SSHO and a competent person?
A competent person is defined by OSHA as someone capable of identifying existing and predictable hazards and authorized to take corrective action. An SSHO is a contract-designated role responsible for overseeing the contractor’s full SOH program at the site. A competent person may support or serve in certain SSHO contexts (such as Level 3), but the roles are not interchangeable.
Does an SSHO need CHST or CSP certification?
Not universally. EM 385-1-1 allows qualifying safety certifications to reduce experience requirements for Level 1 and Level 2 SSHOs, but the contract controls. CHST and CSP strengthen a candidate’s profile without automatically replacing contract acceptance.
