Somewhere in your spec book is a line like “contractor shall provide a certified safety professional.” Simple, until you try to staff it. Does that mean a CSP, the specific senior credential from the Board of Certified Safety Professionals? A CHST? Anyone with an OSHA 30 card? These are different qualifications with different eligibility rules, costs, and candidate pools, and staffing the wrong one can get a submittal rejected or leave you paying for more credential than the project needs. Here is how to tell them apart and match the right one to your project.
First, Separate Training From Certification
The most common confusion on bid day: OSHA 30 is a training course, not a certification. Completing it earns a Department of Labor outreach card showing hours of instruction. Credentials like the CHST and CSP are different animals: accredited certifications from the Board of Certified Safety Professionals (BCSP) that require documented experience, a proctored exam, and ongoing recertification. When a spec says “certified,” find out whether it means a BCSP credential or completed training, because the candidate pools and price tags are very different.
OSHA 30: The Baseline
The OSHA 30-hour construction course is awareness-level training on hazard recognition and OSHA standards, delivered through the agency’s Outreach Training Program. It is the accepted baseline for supervisors, foremen, and anyone with safety responsibilities on a construction site, and many owners and contracts treat it as a minimum for safety staff.
What OSHA 30 is not: proof of competence to run a safety program. It carries no experience requirement or professional exam, and it does not by itself make someone an OSHA competent person or a qualified site safety manager. Federal OSHA cards do not expire, but many owners, and federal requirements such as the USACE EM 385-1-1 SSHO qualifications, expect the course completed within the last five years.
CHST: The Construction Safety Workhorse
The Construction Health and Safety Technician (CHST) credential from BCSP is the certification most often requested for construction field safety roles. Per BCSP’s published criteria, eligibility requires at least three years of experience in construction safety with safety making up at least 35 percent of the role’s duties, followed by a proctored exam and a recertification cycle to keep the credential active. Verify current requirements at bcsp.org, since criteria are updated over time.
For GCs and owners, the CHST signals a construction-specific, field-tested safety professional whose credential can be verified directly through BCSP’s online directory. It is the sweet spot for site safety manager and safety officer roles on most commercial and industrial projects.
CSP: The Senior Credential
The Certified Safety Professional (CSP) is BCSP’s flagship credential for program-level safety leadership. Published requirements include a bachelor’s degree, at least four years of professional safety experience with safety as the primary function, an existing BCSP qualifying credential such as the ASP or GSP, and a comprehensive exam. The pipeline is long, the credential is respected accordingly, and specs for large, complex, or high-hazard projects sometimes name it explicitly.
Worth knowing: the ASP (Associate Safety Professional) is the common stepping stone, generally requiring a degree, at least one year of qualifying safety experience, and its own exam. An ASP holder is often a strong mid-career professional working toward the CSP.
The OSHA Competent Person Is Not a Credential at All
One more term that trips up staffing plans: the competent person. OSHA’s construction regulations define a competent person as someone capable of identifying existing and predictable hazards and authorized to take prompt corrective measures. It is a designation the employer makes for specific activities, such as excavation, scaffolding, or fall protection, based on the person’s ability and authority. No card, course, or certification alone creates a competent person, though training supports the designation.
Side-by-Side Comparison
| Credential | What it is | Core requirements | Best fit |
|---|---|---|---|
| OSHA 30 | Training course (DOL outreach card) | 30 hours of instruction; no experience prerequisite or exam board | Baseline for supervisors and all safety staff |
| CHST | BCSP certification | 3+ years construction safety experience, exam, recertification | Site safety managers and officers on construction projects |
| ASP | BCSP certification | Degree, 1+ year qualifying experience, exam | Mid-career professionals advancing toward CSP |
| CSP | BCSP certification (senior) | Degree, 4+ years professional safety experience, qualifying credential, exam | Program-level and corporate safety leadership |
| Competent person | OSHA designation | Employer-designated ability plus authority, per activity | Required for specific high-hazard activities |
So Which Does Your Project Need?
- Read the contract first. Owner specs and federal requirements override any rule of thumb. On USACE EM 385-1-1 projects, for example, SSHO qualifications are defined in the contract, and credentials like the CHST or CSP can offset experience requirements but do not replace them.
- Typical commercial or industrial project, field role: OSHA 30 as the floor, CHST as the differentiator for the person running site safety.
- Large program, multi-site, or corporate oversight: CSP-level leadership, often supported by CHST field staff.
- High-hazard activities anywhere: confirm competent person designations regardless of which credentials are on site.
Matching the credential to the actual scope keeps you compliant without paying senior-credential rates for a role that does not require them.

Frequently Asked Questions
Is OSHA 30 a certification?
No. It is a training course that earns a Department of Labor outreach card. It is valuable and widely required, but it involves no experience verification, professional exam, or recertification.
How long does it take to get a CHST?
Months at minimum, and years if the candidate is still accruing the required experience. Application review, exam scheduling, and study time add up, which is why projects that need the credential now are staffed with professionals who already hold it.
Can I require a CSP for a field safety officer role?
You can, but expect a smaller candidate pool and a higher cost than the role may justify. Many contractors reserve CSP requirements for program leadership and staff field roles with CHST-credentialed professionals.
Do these credentials expire?
BCSP credentials such as the CHST, ASP, and CSP stay active only through ongoing recertification requirements. Federal OSHA outreach cards do not expire, though owners and some jurisdictions require recent completion.
